EUSCHISTUS. | 59 
The large specimens with bluntly rounded angles have not yet been collected by me in 
company with the other form.” These, agreeing with the E. lwridus, Dall. (the form 
we have figured, with a black-coloured variety), have hitherto been received only from 
Guatemala; but the Berlin Museum contains both forms from Mexico. Prof. Uhler 
also states that in North America “it sometimes occurs in large numbers in late summer 
on bushes in damp situations.” “A whitish bloom often covers the mature specimens 
in this region.” ‘This is also observable in the individuals of this species received from 
Guatemala.
