13. Metopidium moderately low, transversely convex; anterior 

 edge broadly feebly arcuated above the vertex; face 

 short, rugose, 15, uniformis Fairm. 



-. Metopidium high, sides rectilinear and but slightly diverg- 

 ing upwards, its surface transversely almost flat, anterior 

 edge strongly sinuated above the vertex; face long, min- 

 utely striate, 12, brevis Walk, male. 



1. Ceresa diceros Say. PI. 1, fig. 12. 



This common and widely distributed species may be dis- 

 tinguished by its transversely banded pronotum. Amyot and 

 Serville have figured and redescribed it as Ceresa postfasciata. 

 Here it is most commonly found on elder bushes. The hind 

 edge of the last ventral segment of the female is sinuated and a 

 little oblique either side of the deep linear median notch; this 

 notch is as wide as the oviduct and reaches at least half way to 

 the base of the segment. The plates of the male attain the 

 apex of the anal tube. 



2. Ceresa albescens n. sp. PI. 1, fig. 18. 



A little smaller and paler than diceros to which it is closely allied. 

 Pronotum as in diceros but with the suprahumeral horns more acute and 

 recurved and tipped with black, and the apex longer and more slender. 

 Face, front, and superior surface of the pronotum greenish- or yellowish- 

 white with scarcely a trace of the maculations found in diceros; apex of the 

 head less produced, the tylus scarcely longer than the cheeks. Sides of the 

 pronotum paler, ferruginous, becoming somewhat fuscous posteriorly, irro- 

 rate with paler and marked with a pale marginal line and sometimes with an 

 oblique median vitta; protracted apex whitish with a black tip and ferru- 

 ginous median vitta; outer surface of the suprahumerals dark ferruginous, 

 differentiated from the ferruginous sides by the pale lateral line which 

 nearly attains the apex of the horns. Legs and beneath ferruginous, the 

 femora darker. Last ventral segment of the female a very little oblique and 

 rounded to the median notch which is triangular, acute and reaches the 

 middle of the segment. Plates of the male not attaining the apex of the 

 anal tube. Elytra almost hyaline, not smoky brown as in diceros, nervures 

 ferruginous. Length 8-9 mm. 



Described from several examples representing both sexes 

 taken by me at Hamburg and Niagara Falls, N. Y. , and at 

 Effingham, Ks. This species looks much like a small pale
