CRYPTORHOPALUM. 663 
28. Cryptorhopalum brevicolle, sp. n. 
Breviter oblongo-ovale, sat convexum, nigrum, subtiliter fulvo-pubescens, antennis pedibusque rufis, crebre, 
subtiliter punctatum; maris antennarum clava sat magna, articulis minus disparibus. 
Long. vix 2 millim. 
Hab. Panama, Tolé, David (Champion). 
The smallest of our species of this genus, and one in which there is least disparity 
in the sizes of the two joints of the antennal club. The club in the male is a good 
deal larger than it is in the female, and the first joint is distinctly larger than the 
second ; in the female the two joints are even less unequal in size. The punctuation 
of the thorax is quite fine, that of the elytra a little coarser; the surface is not shining, 
and the tawny or flavescent pubescence does not detract much from the black appear- 
ance. ‘Three specimens. 
We have five others almost as small as C. brevicolle, but they apparently represent 
as many different species. 
29. Cryptorhopalum chontalense, sp. n. 
Subhemisphericum, nigricans vel rufescens, dense equaliter griseo-pubescens; antennis pedibusque rufis, 
illarum maris clava elongata.

Long. 23-22 millim. 
Hab, Nicaragua, Chontales (Janson). 
The surface in this insect is densely covered with a pallid pubescence that entirely 
conceals the sculpture, which, however, is extremely fine. The club of the male 
antenna is elongate, the terminal joint a little infuscate, nearly half as long as the 
preceding ; in the female the club is much shorter and is oval. The pubescence of 
the under surface is very dense, and on the metathorax has a slight blue tinge. The 
colour of the surface varies from red to nearly black. In the male the pubescence of 
the last ventral plate forms a very short tuft on each side of the middle projecting 
backwards. Four specimens. 
30. Cryptorhopalum ochraceum, sp. n. 
Breviter ovale, convexum, omnium densissime ochraceo-griseo-pubescens, antennis pedibusque rufis; maris 
antennarum Clava ovali. 
Long. 2-22 millim. 
Hab. British Honpuras, Belize (Blancaneaux) ; Guatemata, Cahabon (Champion). 
Distinguished from all the other forms here described, except C. chontalense, by 
the extremely dense pubescence, which everywhere covers the surface and conceals the 
sculpture. The club of the antenna of the male is moderately large, oval, the terminal 
joint infuscate, fully half as long as the preceding one. In the female the club is 
much smaller. Distinguished from C. chontalense by the very dense ochraceous 
pubescence and narrower form; the tufts at the apex of the last ventral plate of that 
insect are not present in C. ochraceum. Three specimens.
