shaded with very dark brown spots on em- 
bolium; an area at middle, and a triangular 
patch at outer apical angle of corium, pale 
yellowish and translucent; cuneus largely 
black with yellowish spots and a variable 
yellowish area at base. Membrane fuscous 
with a pale marginal spot on either side ex- 
tending irregularly toward middle. Legs 
colored almost as in canadensis Van Duzee, 
but hind femora with large irregular pallid 
spots on anterior face, these spots connected 
by a longitudinal pale bar which does not 
attain subapical pale band. Genital clasp- 
ers and flagellum distinctive for species, fig.

Hasirs.—I have collected this species 
most frequently on the bark of hickory trees 
(Carya sp.) in shaded, humid surroundings. 
The color of this mirid matches the bark so 
closely that it is difficult to see when it 1s 
crouching in crevices on the trunk of the 
tree. Predacious habits are indicated.
