The pale head and pronotum, difference of colouring in tlie 
antennae, absence of the triangular white spots on the corium, and pale 
hinder tibiae, will readily lead to the separation of the species. 
The wonderful resemblance these species have to those of 
pliorus , Hahn., and Mimocoris , Scott, will strike any observer at first 
sight as remarkable, but the ocelli settle the question at once.
