IOO STUDIES IN NORTH AMERICAN MEMBRACID^E 



The male is black with the face and a few irregular marks 

 on the front of the metopidium white, the former with some 

 black points and lines, including the clypeal sutures. On either 

 side of the pronotum is an arched vitta from the humeral angle 

 to the middle of the lateral margin and a transverse band before 

 the apex white. In both sexes the elytra are brown or blackish 

 almost to the apical areoles with a paler subbasal band, and the 

 apex has a deep brown angular patch. 



The Cornell University collection has a fine series of both 

 sexes of this species taken about Ithaca and I have seen a few 

 others from New York and Massachusetts. It probably has 

 about the same range as the preceding species. 



3. Ophiderma flavicephala Goding, PI. 2, fig. 28. 



The female of this species is easily recognized by its 

 castaneous or piceous brown color and the broad yellowish mar- 

 ginal vitta from behind the eye to the middle of the lateral 

 margin ; the face, front of the metopidium and more or less of 

 the apex is paler. The elytra are castaneous at base followed 

 by a hyaline space broadest on the costa and a deep brown 

 apex. The males have the lateral vitta raised so there is a 

 narrow margin of the ground color below it, and there is a sub- 

 apical pale transverse vitta. In all the males I have seen the 

 ground color is paler, and in one the callosities are black. I 

 have before me specimens of this species from Ithaca, N. Y. , 

 Lakehurst, N. J., and Florida. 



4. Ophiderma flava Goding. 



Readily distinguished by its green, or in the dried speci- 

 mens yellowish, color, with the face and base of the metopidium 

 pale, sometimes tinged with fulvous next the eye. Elytra pale 

 fuliginous, darker at apex, before which is a hyaline area. In 

 the Cornell University collection are specimens of this species 

 from Ithaca, N. Y. and Mr. W. T. Davis has taken it on Staten 

 Island. 



5. Ophiderma pallida n. sp. 



Pale yellow with a narrow slender pronotum. Face uneven but almost 

 impunctate; basal margin and the sinuated edge of the cheeks a little re- 

 flexed. Clypeus broad, convex, polished, much produced and incurved. 

 Pronotum low smooth and much flattened; metopidium receding from its
