12. Omotyphus carinatus. (Tab. XLII. fig. 4.) 
Subquadrate, black; the antenne fulvous, the sixth and seventh joints fuscous; thorax with two high tri- 
angular ridges; elytra scarcely pubescent, deeply punctured, with longitudinal tubercles at the base and 
near the apex. 
Length 14 line. 
Head finely rugose, the frontal tubercles in the shape of small oblique dark fulvous ridges, the intermediate 
space with some short pale fulvous pubescence; palpi moderately thickened; antenne extending very 
little beyond the base of the elytra, fulvous, the sixth and seventh. joints fuseous, the fourth and fifth of 
equal length, shorter than the third, the following joints transversely subquadrate; thorax nearly quadrate, 
the sides straight, obsoletely angulate before the middle, the surface here and there clothed with some very 
short fulvous hairs, granulate, with two very highly raised, acute, triangular ridges, the intermediate space 
with some obsolete transverse elevations, the sides with an obsolete longitudinal one; scuteilum thickly 
clothed with yellow pubescence: elytra much wider at the base than the ‘thorax, subquadrate, black, | 
opaque, the punctures deep and not very regularly placed, with scattered spots of very short silvery 
pubescence, which are more distinct below the middle, and the following tubercles or ridges—one, strongly 
raised, at the centre of the base, three, less distinct, below the middle, placed transversely, and two near 
the apex,—the apex perpendicularly deflexed, and with its surface concave; underside black, sparingly 
covered with fulvous hairs; tibiz and tarsi obscure fulvous. ; ,

One specimen. 
HYPOLAMPSIS. (To follow the genus Omotyphus, p. 476.) 
Hypolampsis, Clark, Cat. of Halticide, p. 280 (1860). 
More than thirty species have been placed in this genus by Clark. Its principal 
distinguishing characters are the subquadrate thorax, the incrassate palpi, the single 
spine to the posterior tibia, and the appendiculate claws. 
1 Hypolampsis inornata. 
Subdepressed, black, very finely pubescent; thorax subquadrate, finely granulate; elytra depressed near the 
suture and at the sides, punctate-striate anteriorly, the punctures becoming obsolete posteriorly ; legs 
more or less fulvous, the posterior femora darker. 
Length 2 lines. 
Head finely rugose, black, the lower portion more or less flavous, the frontal elevations short, the clypeus in 
the shape of a triangular ridge; penultimate joint of the palpi but moderately incrassate, flavous; antenne 
extending to about the middle of the elytra, black or piceous, the lower joints more or less flavous at their. 
apex, the third, fourth, and fifth joints nearly equal, more elongate than the following ones; thorax about 
one fourth broader than long, narrower at the base, the sides being slightly widened and rounded before 
the middle, the anterior angles a little thickened, and each with a single hair, the surface somewhat 
depressed at the base, finely granulate, and clothed with thin, short, yellowish-grey pubescence; scutellum 
broad, pubescent; elytra obsoletely depressed below the base, and more distinctly and longitudinally so 
near the lateral margins, the pubescence similar to that of the thorax, the punctures rather strong 
anteriorly, becoming gradually more obsolete towards the apex, where the striz are more prominent ; legs 
pale fulvous, the femora sometimes darker, the posterior tibiee with a small spine at the apex ; claws 
appendiculate. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
This species is of a sombre black colour; and the fine silky pubescence, which covers 
the entire upper surface, gives it an opaque appearance. ‘Two specimens.
