body is black, as are also the eyes. legs, and antenna?. The dorsal sur- 
face is mostly red. with the middle portion of the thorax black. The 
elytra are ornamented with three stripes, a rather narrow sutural one. 
and a shorter black stripe on each side, about midway between the 
suture and the margins. (See tig. 11.) The punctation of the elytra 
is dense and rather line. The form of the body is elongate oval. The 
length is about one-fourth inch or longer. The species belongs to a 
genus represented by several forms in Europe, but it is the sole rep- 
resentative of its genus in this country. Zoologically. Entomoscelis 
is placed near Chrysomela: hence this insect is a relative of the Colo- 
rado potato beetle {Chrysomda [Doryphor<i\ decemlineata). It is char- 
acterized by having a long metasternum and closed front e-oxal cavities. 
having .the tibia? gradually but not strongly dilated at the apices, the 
outer face deeply concave, the distal edge 
obtusely angulated. and the claws simple. 
The egg is elliptical in form, twice or a little 
more than twice as long as wide at its greatest 
diameter, deep blood-red in color, and finely 
hexagonally granulated, the areas being just 
discernable with a one-fourth-inch hand lens.

DISTRIBUTION. 
This species is common to North America. Europe, and Asia, and 
evidently belongs to what is known as the circumpolar fauna: in other 
word.**, it is not of recent introduction, but is native to the boreal 
region- of both the old and new world. 
According to Doctor Hamilton Trans. Am. Em. Soc., Vol. XXI. 1894, p. 397 I, it is 
•ry where through the Rocky Mountains at 8.000 to 11.000 feet eleva-
