208 PSYCHE, [May— July 18S9. allow the passage of the largest eggs. There are nowhere the so-called com-partments for nutrition ; each egg fol-lows the other, but the ripe ones are connected by darker funiculi, containing epithelial cells, and around them rounded cells with a nucleus. The interior membrane of the &^^ tubes is structure-less and hyaline, not very easily seen. The exterior membrane is fibrous, and around the larger eggs shows often lacunes and holes filled with epithelial cells with nuclei. The connecting parts around the lacunes are often small and of decided muscular appearance. In the jDart between two eggs the membrane is striated longitudinally. The chorion of ripe eggs in the tubes shows sexangular spaces, the borders be-tween them comparatively wide and hyaline. The centre of these spaces are darker and filled with pavement cells, round, of .015 mm. in diameter, with numerous fine dark spots. I was not able to find the micropyle in ^'g'g'a contained in the ovarium. The micropyle of laid eggs is dorsal a little before the inferior pole ; there are ten to twelve little holes somewhat different in situ^ forming small funnels with a stem as long as the diameter of the holes. Near them numerous filiform sperma-tozoa ( ?) were seen. The eggs are cylindrical, concave on one side, the ends rounded a little ; often one end thicker ; the yolk corpuscula .01 2 to .025 mm. in thickness. The dissected queens of E. rippertii were from Jamaica and Cuba, of T. gil-viisixoxw Rangoon, Burmah. E. rip-pertii is probably the long sought for imago of Termes devastans^ Kollar.-The above is a part of a proposed mono-graph of the anatomy of the terntitina for which a large number of figures have been made. SECOND CONTRIBUTION TO A KNOWLEDGE OF THE AUTUMN LIFE-HISTORY OF CERTAIN LITTLE KNOWN APHIDIDAE.* BY CLARENCE MOORES WEED, COLUMBUS, OHIO. The present paper is the result of a continuation of the study of the autumn life-history of the aphididae^ begun in Illinois in 1S87. The observations here recorded were made at Calumbus, Ohio, during the autumn of 1888, upon the grounds connected with the Ohio State University. * For the first article of this series see Psyche, Nov.-Dec, 18SS, V. 5, p. 123-134. Melanoxanthus salicti (Harris). This species was first described by Dr. Harris in his treatise on insects injurious to vegetation as Aphis salicti.* In the Flint edition of the Treatise, however, Mr. Uhler states in a foot-note that the specific name had been "long ago appropriated by * 15/ ed., 1842, p. 190-191; 2nd ed. 1852, p. 20S-209 Flint ed., 1S62, p. 239.
