llie male. Unfortunately the tip of the abdomen has been so compressed 



it is impossible to describe exactly the form of the last ventral segment, 



but apparently it is short and truncated or feebly rounded behind, without 



a median notch ; the pygofers are long, yellowish, with the narrow 

 margins and the oviduct deep black. The yellow margin of the con- 

 nexivum is narrower than in the male. 



Cicadtda 6-notata^ Fallen. — Island Lake, August 12th. 



Cicadiila lepida^^2i\\ Duzee? — Two females that seem to be pale 

 examples of this species were taken at Island Lake and on Fox Island, in 

 Red Cedar Lake. 



Cicadu/a, sp. — One example from Island Lake. 



Gnathodus viridis, Osborn. — One unusually large example from Red 

 Cedar Lake. This has the basal angles of the scutellum infuscated, but 

 does not seem to differ otherwise. 



Empoasca atrolabis, Gillette. — One specimen taken at Island Lake, 

 August 1 2th. 



Empoasca unico/or, Gillette. Several from Swamp Creek. I have 

 taken this species at Milan, Ohio, and in numbers at Hamburg, N. Y. It 

 is a little larger and deeper green than Empoasca obttcsa, Walsh. 



Empoasca ??iaii, Le Baron. — A pair of this species is in the material 

 from Fox Island. 



Typhlocyba teiierrima, H. S. — Two examples of this European 

 species were taken at Swamp Creek. 



Psylla carpini^ Fitch. — Island Lake. Three examples. In a revision 

 of this group this name will have to be changed, as it is preoccupied by 

 an European species in the same genus. 



Livia, sp. — One specimen, too immature to admit of correct deter- 

 mination. 



THE PUPATION OF EUVANESSA ANTIOPA, L. 



BY JAMES FLETCHER, OTTAWA. 



On the morning of November 8th I was fortunate enough to watch 

 the pupation of a caterpillar of Etivaiiessa antiopa, L. The operation has 

 often been described, but it seems worth while putting another observation 

 on record, which was carefully watched by Mr. Arthur Gibson and myself, 

 from the time the larval skin first burst until the cremaster was firmly
