236 DESCRIPTIONS OP NEW SPECIES. 



asperities (very much as in Leptostylus aculifer), and behind the 

 middle several of these combine to form an elevation, which runs 

 transversely from the side, and then bends abruptly backwards, 

 and is curved to the suture. But the most striking characters 

 are found in the antennae; which are 4 or 5 times as long as the 

 body, very slender, fringed with short fine hair beneath, as in the 

 $ of the other genera of the group ; with the scape extending to 

 the base of the prothorax, the inner edge acute towards the base, 

 2d joint very short, 3d reaching to the extremity of the elytra, 

 4th joint excessively long, nearly or quite three times as long as 

 the 3d, with an apical tuft of stiff bent black hairs on the inner 

 side ; the seven following joints united not longer than the 4th 

 joint. 



The legs are moderate, thighs very feebly clubbed, middle tibiae 

 with an oblique groove on the outer side, hind tarsi much shorter 

 than the tibiae, with the 1st joint as long as the others united. 



564. Ell. asper. Niger, dense breviter cinereo-pubescens, haud pilosus, 

 thorace subinaequali, parce punctate, variegato ; elytris parce punctatis, 

 granulis nigris, parcis asperatis, vittaque nigra sublaterali a basi ultra 

 medium extensa ornatis. Long. 14 mm. 



Cape San Lucas ; Mr. Xantus. I have no doubt from the 

 characters above detailed that the 9 has a long ovipositor. 



EUPOGONIUS LEC. 



565. Ell. pubescens. Plumbeo-niger, aequaliter tenue cinereo- 

 pubescens, et longe villosus, prothorace confertim punctato, latitudine 

 longiore, spina lateral! minuta ; elytris latioribus fortiter punctatis, 

 elongatis cylindricis. Long. 6.5 mm. 



Ohio; Mr. Ulke. More slender than Eu. vestitus (Say) with 

 the pubescence much finer, and altogether uniform and unrnottled. 

 Eu. pauper Lee. seem to be scarcely different from vestitus (Say). 



To this genus belongs Amphionycha subarmata Lee. (Col. 

 Kansas, 22), which as observed (Pr. Ac. Nat. Sci., Phil. 1861, 

 354), bears a deceptive resemblance to A. jlammata Newm., but 

 has the eyes coarsely granulated, and the claws simple and di- 

 varicate.
