200 RHYNCHOPHORA. 
MACRORHOPTUS. 
Macrorhoptus, Leconte, Proc. Am. Phil. Soc. xv. p. 208 (1876) ; Dietz, Trans. Am. Ent. Soc. xviii. 
p. 184. 
Two species of this genus have been described, both from the Southern United 
States, one of them extending into Mexico, whence another is now added. They are 
wholly unlike the Anthonomids in general facies. 
1. Macrorhoptus estriatus. 
Macrorhoptus estriatus, Lec. Proc. Am. Phil. Soc. xv. p. 209°; Dietz, Trans. Am. Ent. Soc. xvii. 
p. 185, t. 5. fig. 2 (head) *. 
Hab. Norvn America, Illinois 2, Kansas 2, Texas }2, California!?.—Norta Mexico, 
Juarez (Cockerelt). 
A single specimen of this species has been sent us from just within our limits. 
2. Macrorhoptus mexicanus, sp.n. (Tab. XI. figg. 21, 21 ac.) 
Black, the tibie and tarsi, and the base of the scape and of the funiculus, ferruginous ; densely clothed with 
long, coarse, grey or brownish-grey scales, the prothorax brown on the disc and whitish at the sides, 
the base of the elytra also whitish, the elytral interstices each with a series of short, fine, decumbent 
sete. Prothorax and elytra densely punctate, the latter without strie. Anterior femora with a short 
triangular tooth. 
Length 21-22, breadth 15-14 millim. 
Hab. Mexico, Guanajuato (Sallé). 
Four specimens. Extremely like I. estriatus, but with the femora, and the antenne 
in great part, black, the femoral tooth less acute. From M. hispidus, Dietz, from 
Arizona *, it differs in having the vestiture a little less coarse, with the sete much 
shorter and finer, and the femoral tooth not so sharp. J. meaicanus has much the 
facies of some of the squamose Barids, amongst which it was placed in the Sallé 
collection. 
Sect. RHYNCHANIDES. 
Orchestides, Lacordaire ; Rkynchenini, Bedel. 
URSIDIUS, gen. nov. 
Mandibles bifid at the apex ; rostrum strongly curved, moderately long, deflexed, the serobes short and lateral ; 
antenne rather long, inserted towards the base of the rostrum, the scape slender, sinuous, clavate at the 
tip, and reach backward to a little beyond the eye, the funiculus 7-jointed, the club elongate-ovate, 
moderately stout, and loosely articulated ; eyes large, rounded (oval as seen from above), and moderately 
prominent ; prothorax convex, about as long as broad, truncate at the base; scutellum very small ; 
elytra much wider than the prothorax, oval ; prosternum exceedingly short in front of the anterior coxe 
which are contiguous ; intermediate coxe narrowly, the posterior coxe more widely, separated ; meta- 
sternum short, convex ; abdomen very convex, segments 1 and 2 connate at the middle, 3 and 4 subequal 
in length, each shorter than 2; legs elongate; posterior femora exceedingly stout and sharply unidentate, 
* We are indebted to Mr. Wickham for a specimen of this species.
