Scymnus, Herbst, contains a considerable number of very small black 
species, easily recognized by their downy surface, and the usually tawny 
tips of the elytra, or margins of the thorax, characters which appear to 
have suggested the generic name, which literally means a young lion ; 
a name, however, which had already been given by Cuvier to a genus 
of fishes of the shark family. Pysllobora, Chev., contains the P. 20-mac- 
ulata, Say, a little species a tenth of an inch or less in length, readily 
distinguished from all our other Coccinellidae by its white color densely 
sprinkled with black dots. Two other and similar species have been 
described, which perhaps are only varieties. (Eneis, Mulsant, is repre- 
sented by the minute <23. pusilla, LeC., only a fifteenth of an inch in 
length, almost globular in form, and of a shining black color. The male 
has the head, sides of thorax and legs yellow.
