RED BUGS. 67 
FAMILY PYRRHOCORIDAE. 
(Red Bugs). 
There is considerable difference between the members of 
the last family and the one now described. Bugs belonging to 
the latter are stouter and much more heavily built; they are 
generally large insects marked with strongly contrasting colors, 
among which red and black are conspicuous. The venation of

broad, ovate, with an opaque upper surface; the under side is 
coated with a fine bluish pubescence. The prothorax is mar-

colored margin extends along the costal margins of the wing- 
covers; the trochanters and the bases of the femora are marked 
with the same color, which varies greatly in intensity in the dif- 
ferent specimens. The males are usually much narrower than 
the females, who measure a little more than one-half an inch 
in length. The younger stages of this insect look quite different 
from the adult ones, being of a brilliant steel-blue color, with
