than the German one used by Taschenberg. He calls it the “ Get- 
reide-Kapuciner ”—the significance of which name is apparent to 
anyone familiar with the appearance of the insects of this and related 
genera. The object of the likeness is the hoodlike prothorax covering 
the insect’s head. 
DESCRIPTION OF THE SPECIES. 
This is one of the smallest of the beetles which are injurious to 
grain in the kernel, being considerably shorter and narrower than 
the grain weevils. The beetle is about one-eighth of an inch long and 
about one-thirty-second of an inch in width, quite narrow, being 
therefore, approximately, four times as long as wide. The form is 
nearly cylindrical; the head is comparatively 
large and prominent, and bent down under the 
thorax in the manner peculiar to most mem- 
bers of the family Bostrychide; the antenne 
are also prominent, as are the eyes and the 
mandibles. The antenne are ten-jointed and 
terminate in a prominent three-jointed club. 
The color is dark brown or castaneous and

ae apiass size. cording to M. P. Lesne, was published by 
ers Fabricius in 1792, antedating the Synodendron 
pusillus of the same writer, by which specific name (Rhizopertha 
pusilla) the insect has generally found mention until very recent 
years. The description reads as follows: 
S[ynodendron]. leve nigrum obscurum elytris striatis, pedibus piceis. 
Habitat in America meridionali Dom. Pflug.
