ANTHRIBIDZ—BASITROPINI. 165 
ANTHRIBUS SORDIDUS. 
Pip, Pig. 27. 
A single, unfortunately rather poorly preserved specimen seems to fall 
in the Basitropini and probably in or very near the restricted genus Anthri- 
bus. The head appears to be quite smooth, but to be ornamented above 
with a large black impressed triangle, the apex forward; the eyes are 
moderately large and transverse, the beak shorter than the head, apically 
narrowed as seen from the side, the antennz nearly half as long as the body 
and coarse, but unfortunately too poorly preserved to show the joints ; nor, 
indeed, is there any apical enlargement to a club, so that probably they are 
broken. The prothorax is well rounded, the surface very faintly, very 
sparsely punctate, the ridge completely basal. Elytra faintly striate. 
Length, 5"; height:at thorax, 15™; length of (probably incomplete) 
antennz, 2°3"™". 
Florissant, Colorado. One specimen, No. 2675. 
CRATOPARIS Schoénherr. 
South America is the principal home of this genus, though species are 
found in almost all parts of the world. In our country we have but two 
species, found in the Atlantic States. The discovery of no less than three 
species in our Tertiaries, one at Florissant, Colorado, and two at Green 
River, Wyoming, may perhaps be looked upon as an indication of a sub- 
tropical climate where they occur.

The cast of a single specimen, showing in relief what should be in 
depression, and presenting a side view, is the sole relic of this species. The 
head is nearly smooth, with very faint and feeble delicate punctures, as well
