reticulate, the sides margined and very much rounded, furnished with an erect black seta on each side

but rather narrower than the head and thorax, deeply and irregularly asperate, the sides margined and 
slightly rounded, furnished with an erect black seta on each side near the shoulder and another behind the 
middle, the apex slightly contracted and pale; antennz long, piceous, or black; legs yellow. Long. corp. 
= lin. =1-1-12 millim. 
Hab. GUATEMALA, Totonicapam 10,500 feet (Champion ?).—Kuror ! 2. 
A single specimen of this species was found by Mr. Champion. It seems strange 
that this very common European insect should occur in such a locality and at so high 
an altitude in Central America. But after the most careful examination, I can discover 
no point of form or sculpture in which this specimen differs from the European 
examples of the female, the sides of the thorax in this sex being always less dilated 
than in the male.

Hab. Guatemaa, Capetillo, San Gerénimo (Champion 1). 
Differs from its allies in the broad and peculiar form of the thorax, and in the short 
and narrow elytra.
