184 Mr. F. P. Pascoe on new Neotropical Curculionidm. 



curved ; eyes large, round ; antennas ferruginous ; prothorax 

 remotely punctured at the sides and in front, more closely 

 at the base ; scutellum quadrate ; elytra parallel with the 

 thorax, finely striate, the interstices flat, each with a row of 

 oblong or linear punctures ; body beneath with scattered 

 whitish scales ; tarsi ferruginous, the claw-joint only slightly 

 exserted. 



I may mention here that M. Fauvel's genus TrigonojJtei'us, 

 which, as the name was preoccupied, he in 1872 changed to 

 Trigonus, is identical with Idotasia, which I published in this 

 work in April 1871 (ser. 4, vol. vii. p. 261). Lacordaire saw 

 nothing in the description that recalls u un Baridiide," with 

 which M. Fauvel had connected it. It is, in fact, with 

 several other genera, related to Arachnopus among the Zygo- 

 pinai. M. Fauvel's species (Trigonopterus insignis) is distinct 

 from the nine or ten now known ; but his name, both generic 

 and specific, is misleading. It is from New Caledonia, 

 and should stand as Idotasia insignis (Fauv.). M. Fauvel 

 published his description in the "Bulletins" of a local society 

 in Normandy. 



Madams crassirostris. 



M. oblongo-ellipticus, supra leviter convexus, niger nitidus ; rostro 

 breviusculo, subvalido ; elytris subtiliter punctato-striatis ; femo- 

 ribus mnticis. Long. 4| lin. 



Hah, Chontales. 



Oblong elliptic, slightly convex above, glossy black ; ros- 

 trum rather stout, scarcely longer than the prothorax, almost 

 obsoletely punctured ; antenna? black, first two joints of the 

 funicle nearly equal in length, the rest very short ,* prothorax 

 conical, longer than broad, finely and remotely punctured ; 

 scutellum very short, broadly triangular; elytra very deli- 

 cately punctate-striate, the interstices broad and flat, the 

 apices rounded and leaving the pygidium entirely uncovered, 

 the latter closely punctured ; body beneath finely punctured ; 

 a well-marked impressed line on the metasternum ; post- 

 coxal portion of the presternum broadly emarginate ; legs 

 with a sparse yellowish pubescence ; femora not toothed. 



A much narrower species than M. corvinus (Fab.), with a 

 shorter rostrum, broader scutellum, and striated elytra.
