90 STUDIES IN NORTH AMERICAN MEMBRACID^E 



14. Cyrtolobus intermedius Emmons 



This is a small dark ferruginous or chestnut brown species 

 in which the dorsum is but very little elevated. The head is 

 lighter in color and strongly punctured with brown and there 

 may be some light marks along the humeral margins. Here 

 the clypeus and lorae are fused as in maculifrontis with their 

 basal suture almost obsolete and their apical margin obtuse and 

 nearly continuing the apical contour of the face. Of this species 

 I have seen but four examples ; two were taken by me about 

 Buffalo, N. Y. , and two from Ithaca, N. Y. , are in the Cornell 

 University collection. These latter are paler with faint suggest- 

 ions of the dorsal median spot and of another mark below this 

 on the margin, the latter apparently the base of the anterior 

 vitta. Cyrtolobus pallidifrontis Emmons is still unknown to me. 



15. Cyrtolobus inermis Emmons. 



Closely allied to inornata Say. Female pale green or yel- 

 lowish in the dried specimen, immaculate. Dorsum moderate- 

 ly elevated and regularly arcuated. Male smaller and less 

 elevated than the female; the pronotum deep black polished, 

 the base and extreme tip brown; crossed posteriorly by two 

 transverse white vittse; one behind the middle interrupted on 

 either side, and a wider one before the pale apex; head choc- 

 olate brown with the clypeus black above ; beneath and legs 

 pale testaceous. Length; male 4, female 5 mm. 



Of this interesting little species Mr. W. T. Davis has sent 

 me several taken at Lakehurst, N. J., including the only males 

 I have seen. I took one female at Ogden, Utah, in July 1900. 

 Although so near inornata Say it has more of the Cyrtolobus 

 aspect and I prefer to place it here rather than in Atymna. 



16. Cyrtolobus griseus n. sp. 



This form, which is very near ctnereus, is of an almost uniform dark 

 cinerous, closely punctured with fuscous. The only conspicous marking is 

 the oblique blackish vitta which in cinereus bounds the hind margin of the 

 anterior oblique vitta. Before and behind this brown band or line the sur- 

 face is a little lighter and there is a suggestion of the median dorsal spot 

 and transverse posterior vitta. In some specimens there is an arcuated 

 longitudinal brown vitta on either side of the metopidium. Here the 

 elytra are hyaline with the costal base ferruginous-grey and punctured, and 

 the apex has a small fuscous cloud. The tergum is black with a broad
