82 STUDIES IN NORTH AMERICAN MEMBRACIDjE 



hyaline, the smoky apex small and pale. Face coarsely punc- 

 tured; clypeus broad, moderately produced, and strongly in- 

 curved. Length 6 mm., height 3 mm. 



Of this form I have seen but three examples, all females, 

 one of these I took at Atlanta, Georgia, in May 1899; another 

 was taken on Staten Island in July by Mr. W. T. Davis, and 

 the third was found by Prof. Barlow at Waltham, Mass. In 

 these the tip of the pronotum just about reaches the apex of the 

 elytral areoles but does not surpass them. In fenestratus and 

 its near allies the pronotum is strongly and regularly arched 

 from its base almost or quite to its apex and represents the 

 typical form of the genus. 



2. Cyrtolobus ovatus n. sp. PI. 2, fig. 14. 



Form nearly of fenestratus but the outline of the pronotum a little 

 more elliptical and the posterior process more produced and acute and 

 distinct^ deflected. Color of the dried specimen soiled yellowish testa- 

 ceous, sparcely but quite evenly dotted with smooth pale points; the dorsal 

 carina minutely dotted with brown and marked with a nearly obsolete 

 hyaline line in the posterior sinus. Face small, closely punctured; the 

 clypeus prominent; abruptly incurved at apex but not exceeding the cheeks. 

 Beneath and legs concolorous, pale; tarsal claws and oviduct fuscous. 

 Elytra nearly hyaline, its apex very faintly smoky. Length 6 mm. 



Described from four females. One of these was taken by 

 me at Atlanta, Georgia, in May and three were taken by Mr. 

 W. T. Davis, two at Lakehurst, N. J., and one on Staten Island. 

 This species is nearest to fuliginosus but the form of the prono- 

 tum is quite different. 



Cyrtolobus arcuatus Emmons must be closely related to this 

 but his figure shows a form much more sinuated posteriorly and 

 he indicates a transverse brown or fuscous vitta behind the 

 middle which is not discernable in this species. 



3. Cyrtolobus fuliginosus Emmons. 



Dr. E. P. Felt has kindly sent me for study, from the 

 State Museum at Albany, an example of what I believe to be 

 the species figured and described by Emmons. It is near to 

 the species here described as ovatus but the pronotum is pro- 

 portionately more elevated with a deeper sinus both before and 

 behind the crest. The face is more convex and uneven; the 

 margin of the cheeks are nearly rectilinear; the clypeus and 

 lorae are more strongly differentiated with the former more
