338 SUPPLEMENT. 
33. Pantomorus sulfureus, sp. n. (Tab. XV. figg. 24, 244, 3.) 
Moderately elongate, convex, black, the tarsi sometimes obscure ferruginous ; densely, uniformly clothed with 
pale green scales and when fresh covered with a yellow exudation, the elytra also set with rather long 
fine erect hairs, the ventral surface pilose. Rostrum flattened, canaliculate, the upper portion slightly 
narrowing forwards; eyes oval, depressed ; antenne moderately slender, joint 2 of the funiculus one- 
half longer than 1. Prothorax transversely convex, strongly so and as wide as the elytra in ¢, much 
broader than long, rounded at the sides, the base bisinuate (appearing obliquely truncate on each side) ; 
densely, finely punctate and obsoletely canaliculate. Elytra convex, oval, the base (as seen from above). 
conjointly hollowed in the middle and obliquely cut off on each side; finely punctate-striate, the 
interstices almost flat. Anterior tibie denticulate; intermediate tibie feebly unguiculate in d ; 
posterior tibie with an oval squamose area at the tip. 
Length 63-114, breadth 23-44 millim. (¢ @.) 
Hab. Mexico, Salina Cruz in Oaxaca, Pacific slope (nad, in U.S. Nat. Mus.). 
Twelve specimens, mostly in beautifully fresh condition. Amongst the described 
Mexican species of the genus this insect can only be compared with P. (Phacephoiis) 
uniformis, from which it is at once separated by the depressed eyes, and the more 
strongly sinuate base of both the prothorax and the elytra. P. suifwreus has the 
prothorax globose in the male, as in P. (Athetetes) globicollis; but the middle tibie 
are much more feebly unguiculate in this sex. The second ventral segment of the 
male is without tubercles. 
PSEUDOPANTOMORUS, gen. nov. (to follow Pantomorus, p. 166). 
Head very broad, short, together with the eyes as wide as the widest part of the prothorax ; eyes very 
prominent, convex, strictly lateral; rostrum short, subquadrate, narrowing a little towards the apex, 
the scrobes narrow, deep, sinuous, descending to slightly below the eyes; prothorax transverse, truncate 
at the base; scutellum minute or invisible; elytra oval, truncate at the base, the humeri distinct ; 
ventral segment 2 about as long as 3 and 4 united; legs short, stout; femora unarmed, the anterior 
pair subangulate ; anterior and intermediate tibiw unguiculate, the anterior pair obsoletely denticulate ; 
posterior tibie with a narrow squamose area at the tip, the glabrous articular area extending upward ; 
tarsal claws connate at the base; body oblong, robust, densely squamose and setose, apterous. 
Type, P. latefrons. 
The single species belonging to this genus may be briefly described as a small 
Pantomorus with a very broad head, short rostrum, prominent eyes, short, stout legs, 
and basally conuate tarsal claws. It bears a superficial resemblance to Caulostrophus 
and various elongate species of Strophosomus (S. ebenista, &c.). 
1. Pseudopantomorus latifrons, sp. n. (Tab. XV. figg. 25, 25a, 3.) 
Convex, black ; variegated above with a dense clothing of light and dark brown scales, the dark brown scales 
on the elytra condensed into a transverse or curved mark below the base, extending forward along the 
third interstice to the anterior margin, an angulate median fascia (not reaching the suture), and a small 
triangular patch on the disc towards the apex, the scales along the exposed basal margin of the head, at 
the base of the femora above, and on the under surface paler or whitish ; the elytra also thickly set with 
long, stiff, erect seta, and the rest of the surface with short setiform scales. Head and rostrum finely 
canaliculate, the rostrum hollowed towards the apex; joint 2 of the funiculus nearly twice as long as 1. 
Prothorax much broader than long, rounded at the sides, in the ¢ not narrower at the apex than at the 
base, densely, finely punctate. Elytra oval, convex, rather short, constricted immediately below the base,
