CAMPTODES. 327 
alone any of our species with insects described from South America. The number of 
species really common to our region and to South America appears, however, so far as 
collections at present enable one to judge, to be very small; indeed only two or three 
are known to me as common to the two regions. I have seen, however, no Camptodes 
from Venezuela. 
The genus has been divided into two sections by Erichson by means of the structure 
of the claws, which in some species have a rather large lobe at the base, while in others 
the lobe is small or altogether absent. This character, though of importance, does not 
satisfactorily divide the genus into two groups, and I have therefore abandoned it, using 
in preference some other characters. Indeed, by two or three minor structural characters 
the genus is so sharply divided into two sections that I have little doubt the two will 
ultimately be considered distinct genera. Ihave at present, however, treated them only 
as subgenera, giving a fresh name to the section with fewer species, and reserving 
Erichson’s title specially for the division containing the larger number of species. 
In addition to those enumerated below we have received a few specimens, which more 
or less certainly represent other species; these I have not thought it proper to attempt 
to characterize with insufficient material. 
All the species of Camptodes are, I believe, found on flowers, and some of them appear 
to be common insects, though many are very rare. 
Subgen. nov. EKucAMPTODES. 
Metasternum much produced in the middle between the intermediate core, its front 
margin indistinct or interrupted there ; terminal joint of antenne pointed ; sutural 
stria of elytra placed at a distance from the suture, the sutural interstice more 
or less punctate. (Species 1-19.) 
1. Camptodes principalis, sp. n. 
Rotundatus, convexus, late rufus, capite prothoraceque nigris nitidis, hoc ad basin utrinque rufo-maculato ; 
elytris lete viridibus, crebre sat fortiter punctatis. 
Long. capite inflexo 7 millim. 
Hab. Mexico, Jalapa (Hoge, M. Trujillo). 
Antenne red, with the club concolorous. Thorax shining black, with a large red 
mark on each side at the base, very sparingly and finely punctured. Elytra rather 
coarsely punctate, with traces of striation between the punctures. Pygidium coarsely 
punctate. Male with the pubescence on the mentum, submentum, and front of pro- 
sternum longer and denser, and the hind margin of the last ventral plate bisinuate ; in 
this sex the extremity of the hind body exhibits in the middle some longer pubescence, 
the pubescence being attached to the extremity of the supplementary segment, which, 
except for this, is quite internal.
