THE BROAD-NOSED GRAIN WEEVIL. 23 
In June, 1909, Mr. G. C. Champion 13 published a note on this 
species, having particular reference to its synonymy and distribution. 
In October of the same year 14 he furnished a synoptic table of four 
species of the genus, figured the species under consideration, and gave 
the full synonymy and a list of known localities in which it occurs, 
notes on variation, etc. 
SUMMARY OF LIFE HISTORY AND HABITS. 
In addition to what has been said in the introductory portion of 
this article, it may be added that in Insect Life 9 the species of Caulo- 
philus a are stated to have similar habits to other Cossonini, which 
live under bark and in decaying wood. Doubtless this was the 
original habit of the genus, and perhaps even at the present time it 
bores in dead roots and perhaps even in twigs, but there is at hand 
no evidence that such is the case. 
To distinguish this species from the granary and rice weevils it 
may be called the broad-nosed grain weevil, the descriptive adjective 
being a translation of the specific name latinasus. 
BIBLIOGRAPHICAL LIST. 
As the literature of this species is limited and the references have 
not hitherto been brought together the systematic papers as far as 
known are included in the following list. References to C. sculptu- 
ratus are also included on the strong probability of its specific identity 
with latinasus: 
1. Say, Thos. — Descriptions of North American Curculionides, p. 30, July, 1831. 
(LeConte edition, 1859, p. 299.) 
Original description as Ehyncholus latinasus, from Florida.

Description of genus Caulophilus and of C. sculpturatus , with distinctions from Phlceophagus 
and Caulotrupis. Original colored figure of C. sculpturatus.

1861, p. 368.

Description as Cossonus pinguis; Boheman's description of R. latinasus quoted and the species 
doubtfully referred to Stenoscelis.

pp. 499, 586. 
Characterization of the genus; notes on C. sculpturatus with reason for its separation from Rhyn- 
colus cylindrirostris Oliv. (lignarius Marsh.). 
a The generic name Caulophilus, from two Greek words meaning literally a stalk 
lover, was applied by deduction from analogy, since Wollaston, writing later, says 
nothing of the habits of the species from observation, his type having been picked up 
under a stone.
