Hottes The two species described herewith, were sent me as imma-ture specimens by Mr, Dennis Grassi who collected them on branches of Pinus edulis near Springerville, Arizona. It is a pleasure to acknowledge his assistance. It was not until one of the species had been determined as new, that I became aware of the fact that I had taken three specimens a year earlier. Cinara rustica s.sp. Oviparous female. Size and general color: — Length from vertex to end of anal plate vary-ing from 3.00-3.33 mm. Head black slightly powdery. Prothorax black with a few spots of powder. Meso and metathorax black mottled with powder. Anterior portion of abdomen black, almost free from powder, whatever powder is present is confined to a small amount at sides and an indistinct powdery median stripe. Just anterior to the cornicles there is a wide band of powder. The cornicles are black. Median to the cor-nicles there is an indistinct powdery stripe. Surface of abdomen not powdery reticulated, somewhat rough, and with some polish. Posterior portion of abdomen faded black with a greenish tinge. Ventral surface of abdomen powdery, not banded at rear. First antennal segment con-colorous with head, second and third antennal segments pale dusky and uniform in color, fourth and fifth antennal segments pale dusky with ends much darker, sixth segment uniform dark dusky. Metathoracic femora pale at base to about middle, remainder much darker. Hind tibia with short region near base dusky, this followed by a region which is dusky yellow, this region is followed with dark dusky. Tarsi dusky. Cornicles with constricted area much darker than basal region. Posterior to the cornicles there are a few irregular shaped pigmented spots. An-terior to the Cauda there are two pigmented spots. Head and thorax. — Antennal segments with the following lengths: III .34-.375mm., IV .135-.15mm., V .15-.18mm., VI .075-.10 + .03mm. Third antennal segments may be without sensoria, or with one, the fourth antennal segment has the primary sensorium only, the fifth segment has the primary and one secondary senorium, both of these are large and have wide rims. Antennal hair moderately numerous, fine, and with exceptions almost at right angles to segment. On the third segment the hairs vary in length from shorter, to just longer than width of segment. 14— Proo. Biol. Soc. Wash., Vol. 69, 1956 (83) «EP7 pmm
