hollowed down the middle. Prothorax transverse, rounded at the sides, nearly as wide at the apex as at 
the base; feebly granulate and densely finely punctate. Elytra at the middle nearly twice as wide 
as the prothorax, convex, rounded at the sides ; with ten rows of scattered rather coarse punctures placed 
upon almost obsolete striz, the punctures separated one from another by a smooth transverse or rounded 
tubercle. 
Length 101, breadth 43 millim. (@ ?)

One specimen, from the last collection made by Hoge, and given to us for description 
by Signor A. Solari. 
TRACHYPHLGINA. 
TRACHYPHLG@OMIMUS, gen. nov. 
Rostrum short, stout, the scrobes lateral, deep, descending direct to the lower anterior margin of the eyes ; 
eyes coarsely facetted, not prominent, moderately large; antenns with a gradually widened scape, 
reaching the front of the prothorax, the funiculus rather slender, joints 1 and 2 equal in length, 
3-7 short and moniliform, the club stout and ovate; mentum small; prothorax transversely oval; 
scutellum very minute or not visible; elytra short, oval; metasternum short, the episterna very narrowly 
exposed; ventral segment 2 as long as 3 and 4 united, the first suture feebly arcuate ; femora clavate, 
unarmed; tibia sinuate within, strongly unguiculate, and each armed with a row of closely placed stiff 
bristles at the apex (fig. 816); tarsal claws long, divergent; body densely squamose and setose, and also 
coated with an earthy incrustation, apterous. 
Type, 7. spurcus. 
This genus also includes Trachyphlaus solitarius, Sharp, both species differing from 
Trachyphleus in having the tibiz closely ciliate with short stiff bristles at the apex 
(in Trachyphleus they are armed with from three to five tooth-like spines along the 
apical margin), the funiculus more slender, and the prothorax more developed. 
Hypsometopus, type H. inguinatus, Kirsch (the type of which I have seen), from 
Colombia, comes near these Mexican insects; but it has the scrobes descending at 
some distance before the eyes, the antennal club longer, the legs more elongate, &c. 
The N.-American Phyxelis, Schénh., has superiorly placed scrobes, &c. 
1. Trachyphleomimus spurcus, sp.n. (Tab. XV. figg. 31, 31a, 3.) 
Oblong-ovate, black, the antenne (the scape excepted) and tarsi ferruginous; densely clothed with brown 
scales, which are partly hidden beneath an earthy incrustation, the entire surface (antenne and legs 
included) also set with rigid, scattered, stout sete, those on the elytra long, clubbed, and uniseriately 
arranged down each interstice. Rostrum subquadrate, feebly transversely depressed at the base, 
obsoletely canaliculate, the head also feebly depressed behind the eyes. Prothorax transverse, strongly 
rounded at the sides, a little wider at the base than at the apex; uneven, closely punctured and 
subgranulate, obsoletely canaliculate. Elytra somewhat flattened on the disc, coarsely punctate-striate, 
the alternate interstices costate. 
Length (excel. rostr.) 4, breadth 2 millim.
