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.

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
