Key to Species. 



1. Uniformly fulvous-yellow with the elytra whitish-hyaline fulvus 



Front banded with black ; various dark markings 2 



2. Elytra with a longitudinal fuscous vitta at apex pictifrons

M. pictifrons Stal. 



Berl. Ent. Zeit, vi, 307, 1862. 



Front broad marked with a conspicuous black band at base and 

 another at apex ; color a dull fulvo-testaceous, the outer angles of 

 the mesonotum marked with a fuscous vitta; elytra hyaline, the 

 nervures heavy and distinctly dotted ; a sinuous fuscous vitta from 

 the base of the inner anteapical areole to the inner apical angle 

 of the elytra. Length 5 mm. This species has been reported 

 from New York to the District of Columbia and must occur in 

 Connecticut. 

 M. sordidipennis Stal. 



Berl. Ent. Zeit., vi, 308, 1862. 



Differs from the preceding in being more strongly tinged with 

 fulvous, in having a wider vertex, and in having no apical fuscous 

 vitta on the elytra and the nervures more slender. It lives 

 throughout the eastern United States and Canada.

 1911, II July, 1920 (B. H. W.). 



Subfamily Issinae. 



Thick-set insects usually with broad heads, more or less trun- 

 cated before but occasionally produced a little. The elytra when 

 fully developed are often convex and more or less gibbous near 

 their base. 



Key to Tribes. 



Head rostrate-produced, or having the clypeus strongly inflexed and 

 shouldered, thus forming nearly a right angle with the line of 

 the front Caliscelini 



Head not rostrate-produced, the clypeus on nearly the same plane as 



the front Issini 



Tribe CALISCELINI. 



In this tribe the elytra are usually short, rarely surpassing the 

 middle of the abdomen; long- winged individuals may, however, 

 be found in any of the species.
