Since the publication by one of us (Bishop, 1924), of the Revision of the Pisauridae of the United States, a number of specimens have come to hand which provide material for the description of four males not previously known. Several specimens of Dolomcdcs pinicola Hentz were received from Mr. Stanley Mulaik of Edinburg, Texas, and Dr. W. J. Gertsch of the American Museum has sent us specimens of Thanatidius dnbins Hentz, Dolomcdcs striatiis Giebel and Thaninasia pcreyrina Bishop. The records of a few additional species are added.

The specimen described by Chamberlin as Trip pus lamprus is a young individual less than half grown. $ . Length, 10 mm. Cephalothorax, length, 5 mm., width. 4.5 mm. Cephalothorax with the ground color orange yellow, on either side of the mid-dorsal line a broad dusky band with a narrow anterior extension enclosing a light oval area back of the eyes, extreme margins slightly dusky; the light areas of the sides of the thorax clothed with soft white hairs, the light area back of the eves and the duskv bands clothed with brown 240 ENTOMOLOGICAL NEWS | X()V., '36 hairs ; extreme margin of the cephalothorax and median ocular area clothed with long white hairs directed forward. Viewed from above, the cephalothorax is broad, evenly rounded on the sides to the posterior eyes then sharply converging to the rather truncated front ; viewed from the side, the posterior declivity short and steep, then gently rounded over to the cervi- cal groove, top of head flat and nearly level. Posterior eyes in a strongly recurved line, equal, the median separated by three-fourths the diameter and from the lateral by the diameter. Anterior eyes in a very slightly recurved line, the median larger than the lateral, separated by two-thirds the diameter and from the lateral by one-third the diameter. Median ocular area broader than long, height of clypeus two and one- half times the diameter of an anterior median eye. Chelicera orange yellow, lower margin of the furrows with three teeth on one and four on the other. Abdomen above yellowish white, finely reticulated and with a median, basal, lanceolate area smooth, followed by two rows of small brown spots slightly converging and decreasing in size posteriorly. Sides of abdomen dull yellowish, clothed with short white hairs ; venter yellowish and clothed as on the sides ; back of the epigastric furrow a broad white area, widest in front, converging posteriorly and marked with two indistinct lines of brown dots extending to the spinnerets. Legs and palpi dusky orange yellow, the legs in order of length 1-4-2-3; 29-27-25-21 mm. respectively; tibiae of first and second legs beneath with 4-4 spines, the apical short, others long but not overlapping. Sternum orange-yellow with a broad submarginal dusky band. Labium and endites orange yellow. Tibia of palpus moderately long and stout, the distal meso- ventral angle produced into a broad lobe ; the apophysis broadly attached at base, deeply excavated distally and armed at base on the ventral side with a short, curved black tooth. The tegulum is roughly horseshoe-shaped, the distal arm longer and broader than the ventral ; the median apophysis narrow at base, widened distally and expanded into a thin transparent flange which is drawn out to a beak-like point on the lateral side; the long, slender, whip-like embolus arises at the back of the bulb and curves forward and ventrally, its tip resting in the groove of the fulcrum and covered by the membranous conductor. By the form of the tibial apophysis and the structure of the bulb, this species is evidently related to Dolomedes (ill'inciis and D. script us. xlvii, '36] ENTOMOLOGICAL NEWS 241 Fig. 1.

Femur of the palpus long and slender, somewhat compressed at base and slightly widened distally ; armed above with a trans- verse, curved row of four dark spines just back of the tip. followed by a row of three spines along the mid line; patella short and with the sides nearly straight, slightly convex above and armed above at base with a long slender black spine; tibia slender at base, evenly widened distally, produced at the tip ventromesally into a distinct tooth-like projection ruid dorso- laterally into a broad ear-shaped apophysis diagonally truncate at tip ; tibia armed above at the middle of its length with a single long black spine and mesally by a pair of black spines. In the form and position of the tegulum and embolus. this species closely resembles D. pinicohi; the median apophysis, however, is of nearly uniform width throughout and the tip on the lateral side is a much sharper point. Since this species was reinstated in 1924, a number of addi- tional specimens have been found. NEW YORK : Mendon Ponds, Monroe Co., Sept. 28, 1928, 1 juv. $ (Bishop).

Gertsch has compared this specimen with one from Southern Pines, North Carolina, and found them to he identical and there are several males in the collection of the Museum of Comparative Zoology at Cam- bridge from the same locality. '' . Cephalothorax, length, 4.5 mm. ; width, 3 mm. The cephalothorax has the characteristic markings of the female. They consist essentially of a broad, median, brown band in which there is a light line through the dorsal groove ; the light line widens anteriorly to the width of the ocular area then nar- rows and passes between the posterior median eyes ; sides of the cephalothorax dull yellowish. The eyes are in four rows as in the female but the posterior lateral and median eyes are slightly larger than the anterior. The legs are too much broken to determine the relative lengths. Femur of palpus rather long and slender, somewhat widened distally ; patella short, convex above ; tibia viewed from above, narrow at base and with the mesal side nearly straight, strong! v protuberant on the lateral side, at the middle of the length, where the apophysis is borne; apophysis a broad, black, shovel- shaped process bearing on its dorsomesal angle a long sharp spine. Base of cymbium, on the lateral side with a low rounded protuberance ventrad of which there is a longer, heavier pro- cess. The bulb of the palpus is comparatively simple ; the embolus arises on the mesal side, makes a half-turn around the bulb next to the cymbium and emerges near the tip on the lat- eral side.

Femur of palpus narrow at base, concave on the mesal side and widened distally, marked above near the middle of its length by an indistinct grayish patch and armed above with six long, stout, black spines, four fornrng a transverse cu.-ved line near the tip of the segment, the other two in the mid-line near the middle of the length; patella short, stout, strongly con- vex above and armed above near base with a slender black spine and distally by a very long, stout, sinuous, black spine; tibia narrower than patella and with the sides nearly straight, aimed above at base with a pair of long black spines and on the mesal side at base by a basally stout, apically slender black spine set at right angle to the segment ; the tip of the tibia above strongly compressed and produced into a long point from the lateral side of which the tibial apophysis extends laterally at nearly a right angle ; the tip of the apophysis is slender, flattened and curved forward. The bulb of the palpus differs markedly from that of other genera of Pisauridae and in the absence of sufficient material to permit the expansion of a palpus for detailed study, the parts are difficult to homologize. The tegulum is narrow and is exposed only at the base of the bulb; the embolus is a stout, black, sharply curved rod which arises at the back of the bull), makes one complete turn around the end, the tip emerging on the- lateral side above a long stout process which extends the entire length of the bulb on the lateral side. The t\pc of the species, a female, was taken at Hot Springs, ARKANSAS. TEXAS: Rio Grande City, Starr Co., July, 1934, 1 ad. S, (Allotype) 1 juv. $, 1 juv. 9 (Mulaik).
