278 RHYNCHOPHORA. 
HOPLORRHINUS. 
Hoplorhinus, Chevrolat, Bull. Soc. Ent. Fr. 1878, p. eviii. 
The two described members of this genus both inhabit Brazil, and one or two other 
southern forms exist in collections. The two from our region are not very closely 
allied to any of them. 
1. Hoplorrhinus mexicanus, sp.n. (Tab. XIV. figg. 15, 15 a, d, ¢; 16, 2.) 
Elongate, narrow, moderately convex, shining; testaceous, the elytra with a broad, common, outwardly 
widened, post-median fascia, and the suture and lateral margin thence to the base, black ; clothed with a 
very fine yellowish pubescence, the elytral interstices each with a series of short, semierect, similarly- 
coloured, fine, bristly hairs, these also extending over the pronotum. Head minutely punctate, the eyes 
large, finely facetted, and somewhat widely separated ; rostrum (¢ ) slender, feebly curved, a little longer 
than the prothorax, flattened above, dull and alutaceous, finely carinate down the middle and also at the 
sides, (Q ) of the same length, but more curved and convex above, punctured at the base, and for the rest 
smooth and shining ; antennz slender, in the 9 inserted at about one-third from the base, and in the ¢ 
at a little behind the middle, of the rostrum, joints 1-3 of the funiculus elongate, 1 much longer than 2, 
2 and 3 subequal in length, the club ovate, with joint 1 shining and as long as the others united, the 
scape reaching to the middle of the eyes. Prothorax a little longer than broad, rounded at the sides, 
narrowed and somewhat attenuate anteriorly and also narrowed behind, distinctly constricted in front, 
the surface alutaceous and also minutely punctate. Elytra elongate, slightly wider than the prothorax, 
parallel to the middle, truncate at the base, with the humeri a little produced in front; finely seriate- 
punctate, the interstices flat and closely, minutely punctate. Beneath alutaceous and minutely punctate. 
Legs elongate, the femora each with a small tooth, the tibie and tarsi slender, the claws feebly angulate 
towards the base. 
Var, The dark markings of the elytra nearly or quite obsolete. 
Length 4-43, of the rostrum 12, breadth 14-14 millim. (¢ 9.) 
Hab. Muxico, Manantial, ? Sierra de Durango (ez coll. Flohr). 
Numerous specimens of both sexes, varying in the coloration of the elytra. 
2. Hoplorrhinus crispus, sp.n. (Tab. XIV. figg. 17, 17a, 2.) 
Elongate, narrow, moderately shining, testaceous; sparsely clothed with a very fine, scattered, yellowish 
pubescence, the upper surface with intermixed, short, curved, bristly, similarly-coloured hairs, which are 
semierect on the elytra and arranged in a somewhat close series down each of the interstices. Head 
finely alutaceous ; eyes large, coarsely facetted, and somewhat widely separated ; rostrum (¢) curved, a 
little thickened towards the base, considerably longer than the prothorax, punctato-sulcate to near the 
middle, and polished and very sparsely punctate thence to the apex ; antennew inserted near the centre of 
the rostrum, joint 2 of the funiculus slightly shorter than 1 and about twice as long as 3. Prothorax 
nearly as broad as long, rounded at the sides, almost equally narrowed in front and behind, feebly 
constricted at the apex, the surface alutaceous and also sparsely punctate. Elytra elongate, a little wider 
than the prothorax, very finely seriate-punctate, the interstices closely punctate. Legs moderately long, 
the femora each with a rather long, acute tooth. 
Length 33-32, breadth 1j-13 millim. (¢.) 
Hab. Britist Honpuras, Rio Hondo (Blancaneaux); GuatemaLa, Chacoj in the 
Polochic Valley (Champion). 
Two specimens. Smaller and less elongate than H. mevicanus, the rostrum more 
curved, shorter, and in the male polished beyond the middle, the prothorax shorter,
