Hypsonotus mexicanus, Gory, in coll. Pascoe *. 
Oblong, rather convex, black or piceous, the legs often in part ferruginous; thickly clothed with small pale 
brown, cupreo-cinereous, or cinereous scales, the elytra with several cinereous or whitish (or, rarely, 
metallic) patches—one, triangular, rounded, or transverse, at about the middle of the disc, another in a 
line with it on the flanks (these two sometimes connected, or the outer one extending forward to the 
shoulder), an angulate curved subapical fascia (in some specimens very broad, in others divided into two 
spots), and (rarely) an oblong patch at the base of the suture,—the upper and under surfaces and the 
legs occasionally with additional intermixed smaller patches of green or cupreous scales ; the surface also 
set with scattered, short, fine, pallid, decumbent sete. Rostrum about as long as the prothorax, rugosely 
punctate and finely carinate; head with an oblong inter-ocular fovea, closely punctate ; joints 1 and 2 
of the funiculus subequal in length. Prothorax transverse, arcuately narrowed anteriorly, densely, 
confluently punctate and also granulate. Elytra much wider than the prothorax, acuminate at the 
apex, oblong-subtriangular in g, subparallel in their basal half in 9, the humeri prominent, obliquely 
truncated in front; coarsely punctate-striate, the interstices rugulose and feebly convex. Beneath finely 
punctate and sparsely granulate ; first ventral segment slightly hollowed down the middle in g. Tibi 
strongly unguiculate in ¢, unarmed in Q. 
Length 8-15, breadth 23-6 millim. (¢ 2.)

A common insect in the warmer parts of Central America, ranging from the 
Mexican State of Vera Cruz to Colombia. It superficially resembles the Palearctic 
Alophus triguttatus. ‘The elytral markings vary greatly in development, sometimes 
becoming transversely or longitudinally confluent, and sometimes barely traceable, and 
occasionally (as in most of the examples from the Polochic Valley) (fig. 8) metallic. 
The specimens (2) in the British Museum, standing under the above-quoted MS. 
interstices convex, here and there transversely confluent on the disc.— Q. Larger and broader than 
H. macularis (3; clothed with brown and cinereous scales, the elytra much longer than in ¢, some- 
times with the disc and apex mottled with brown and the scales on the rest of their surface cinereous, 
the two small obliquely placed spots more or less distinct. Length, g 11, 9 14-18; breadth, ¢ 43, 
Q 54-73 millim. 
Hab. AntitiEs, Grenada and St. Vincent. 
One male, from Grenada [type], and seven females, from St. Vincent, the latter mostly worn, presumably 
belonging to the same species, and evidently distinct from the variable H. macularis. In these insects there 
is no trace of a curved paler subapical fascia, and the two small whitish spots on the middle of each elytron 
are more obliquely placed than in H, macularis.
