An abundant species throughout our country, extending northwards into Colorado 
and Arizona, and southwards into South America. 
In the long series of about 130 examples of both sexes before me, I find that the 
elytra vary a little in length, and also slightly, according to maturity, in the intensity 
of the punctuation; well developed males (one of which is figured by Dr. Horn, loc. 
cit.) may, however, always be known, as pointed out by Dr. Horn, by the broad angular 
horizontal extension of the sides of the head, concealing a small and short horn beneath 
in front; poorly developed males have the sides of the head formed very much as in 
D. cucujiformis, but have the antennary orbits much less extended laterally and almost 
rounded externally, and the tubercle beneath almost obsolete ; the thorax in both sexes 
is only slightly constricted behind the middle, and, as in the other species, the disc 
in some examples appears to be broadly flattened and feebly concave. 
This is the smallest species of the genus. 
D. plana is sometimes to be seen in collections labelled D. furcata, and under other 
MS. names. 
2. Doliema cucujiformis. 
Schedarosus cucujiformis, Reitter in litt. 
Longer and larger than D. plana; the head broader and more coarsely punctured ; the antennary orbits more 
swollen in the female, in the male broadly and angularly produced (but only slightly) on each side in front 
(extending but. little beyond the epistoma, which in this sex is deeply transversely impressed on each side 
in front), beneath which is a short tubercle ; the prothorax rather more convex anteriorly, more constricted 
behind, more evidently punctured, the hind angles usually sharper and more prominent; the elytra com- 
paratively longer, more evidently punctate-striate, the interstices more distinctly punctured.

Numerous examples, Also a common species in our country, and often found in 
company with D. plana. D. cucujiformis is very closely allied to D. platisoides, Pascoe, 
the type of which (a female), kindly lent me for examination by the describer, only
