A. (Lepyromia) 4-angularis Say is also similar in habits and 
appearance, being brownish, covered densely with microscopic 
hairs, and black beneath. Here the wing-covers are marked with 
two oblique darker brown bands, which run together near the 
middle forming a sort of cross. 
In the allied genus Clastoptera we have a number of insects 
that are quite different in shape, possessing a blunt head and a 
plump and short body, sometimes nearly hemispherical. All are 
small, seldom measuring more than one to two-tenths of an inch 
in length.

Clastoptera proteus Fitch. (The Cranberry Spitile-insect). 
In its younger stages it is found in the early part of June 
in little masses of froth upon the growing shoots of the cranberry 
vines; it also occurs upon the blueberry bushes in swampy places. 
The adult insects, which vary greatly in coloration and mark- 
ings, hence the name proteus, jump with the agility of fleas. A 
very distinct example is deep black, highly polished, marked with 
two yellow bands on the vertex and one on the thorax, with two 
oblique stripes on the base of the wing-covers; and a cross-bar 
near the tip. At the base of the pale brown membrane and also
