230 HETEROMERA. 
10. Anthicus foveiventris. (Tab. X. fig. 9, ¢.) 
Elongate ; the head reddish-testaceous, shining; the prothorax fusco-ferruginous, dull; the elytra rather 
shining, piceous, with a transverse testaceous fascia a little below the base and another beyond the middle, 
the suture very narrowly and the space beyond the second fascia brownish; the upper surface clothed 
with fine appressed pubescence, with scattered intermixed erect bristly hairs. Head broader than long, 
a little dilated at the sides behind, with a shallow occipital groove, very finely, shallowly, and closely 
punctured ; the eyes black, coarsely granulated, large, rather prominent ; antennee moderately long, very 
stout, submoniliform, joints 9 and 10 transverse, 1-7 reddish-testaceous, 8—11 piceous-brown, the tip of 
the eleventh ferruginous; prothorax longer than broad, a little narrower than the head, rounded at the 
sides before and strongly constricted behind the middle, the anterior portion transversely convex, the 
posterior portion short and feebly dilated at the base externally, the base without distinct margin, the 
flanks moderately excavate, the surface finely rugulose, dull; elytra rather long, a little narrowed in 
front, with a deep transverse post-basal depression (occapied by the first fascia) and moderately convex 
beyond this, the humeri somewhat obtuse, the surface very finely and closely punctured; legs very stout 
(the femora especially), testaceous, the tibie in great part and the hind femora (except at the base) piceous, 
the four hinder tarsi fusco-testaceous ; fifth ventral segment deeply foveate in the middle behind and 
emarginate on either side at the apex, the median portion angsty produced, and all the tibie slightly 
sinuate on their inner side, in the male. 
Length 3 millim. (<¢.) 
Hab. Guatemata, El Reposo (Champion). 
One male example, found in the Pacific coast-region. 
This and the following species have the antenne very stout and submoniliform, and 
the elytra piceous, with two testaceous, almost straight, transverse fascie. They are not 
closely allied to any others known as yet from Central or South America. In A. fovei- 
ventris the legs are very stout, the femora especially, and the transverse post-basal 
depression of the elytra is deep; the male has all the tibie a little sinuous on their 
inner edge and somewhat dilated, and the last ventral segment very deeply foveate in 
the middle. 
11. Anthicus crassicornis. 
Very closely resembling A. foveiventris, and differing only as follows:—The antenne shorter, a little more 
slender towards the base, and with joints 7-10 transverse; the elytra proportionately narrower, less 
densely pubescent, and not so closely punctured; the legs not so stout, the anterior and intermediate 
femora also infuscate in their outer half; all the tibie slightly sinuate within, the hind pair distinctly 
curved (not straight) without, and the fifth ventral segment truncate at the apex and unimpressed, in 
the male. 
Length 3 millim. (<¢.) 
Hab. Guatemaa, San Gerénimo (Champion). 
One male example. This insect so exactly resembles the preceding at first sight as 
to appear indistinguishable from it; the form of the fifth ventral segment in the 
male is, however, totally different from that of the same sex of A. foveiventris, and this 
peculiarity is accompanied by the other above-mentioned less important points of 
distinction. Owing to the more strongly transverse penultimate joints and the rather 
less stout basal ones, the antenne appear to be more widened outwardly than in 
A. foveiventris ; the hind tibie in the male are distinctly curved outwardly in A. crassi- 
corms, the outer edge being almost straight in A. foveiventris.
