slightly widened, near the base externally; rostrum (2) long; prothorax 
feebly binodose on the disc, the lateral tubercles small; elytra deeply 
punctate-striate, the alternate interstices more or less raised; meta-

1. Hypoceliodes inzqualis, sp.n. (Tab. VIII. figg. 28, 28 a, ¢.) 
Short ovate, broad, robust, black, alutaceous ; the under surface and legs sparsely clothed with small, cinereous, 
hair-like scales, the upper surface almost bare. Head densely, rugosely punctate, carinate on the vertex 
and depressed between the eyes; rostrum very stout, arcuate, as long as the prothorax, rugosely punctate, 
not carinate. Prothorax rapidly narrowing from the base, abruptly constricted in front ; the disc gibbous 
and canaliculate, the dorsal elevations separated from the prominent lateral tubercles by an oblique sulcus ; 
the anterior margin somewhat produced and notched in the middle; the surface shallowly, confluently 
punctate. Elytra very broad, rounded at the sides, depressed at the base, below the shoulders, and on 
the dise beyond the middle ; with interrupted rows of coarse, deep, oblong punctures placed in shallow 
strie, the interstices here and there transversely confluent, alutaceous, and minutely granulate. Meta- 
sternum declivous, the excavation reaching to the apex. Ventral segment 5 foveate in the middle in the ¢. 
Anterior and intermediate femora with a minute tooth. Intermediate tibis rounded at the base externally, 
unguiculate at the inner apical angle in the ¢, unarmed in the 9. 
Length 4-43, breadth 34-32 millim. (d 2.) 
Hab. Panama, Bugaba (Champion). 
Three specimens. This insect has the facies and sculpture of a Chlamys, except 
that the shape is different. ‘The very uneven, seriato-foveolate elytra separate it from 
all others of the genus. 
2. Hypoceliodes granulatus, sp. n. 
Short ovate, broad, robust, black, alutaceous; the under surface and legs sparsely clothed with narrow 
cinereous or whitish scales, the upper surface almost bare, but often coated with a fulyous waxy secretion.
