184 DESCRIPTIONS OP NEW SPECIES. 



Enaphalodes simplicollis, without generic definition. It is use- 

 ful to mention, as showing the instability of the characters relied 

 on as of value in the classification of CerambycidaB, that there is 

 before me a specimen of E. rufulum in which the left front 

 coxal cavity is open as much as in any Hesperophanes. 



Thersalus bispinus Pascoe, Journ. Ent. ii, 372 (1855), is 

 closely allied to if not identical with E. (R.) atomarium, and 

 the fact that it was previously described (Trans. Ent. Soc. Lond., 

 3d, i, 562) as Phacodes, indicates tolerably clearly that the genus 

 Phacodes should be partly suppressed, as being merely a slight 

 Australian geographical variation upon Elaphidion. 



7. E. mucronatum (Fabr.), Hald., = muricatum Hald. 



8. E. incertum Newn., = aspersum Hald., = vicinuni Hald. 

 = neglectum Lee. 



9. E. truncatum Hald., which has been cited as synonymous 

 with E. inerme Newman, is quite distinct by the characters given 

 above. The type, now in my possession, is probably Mexican, 

 but the species has since occurred in Texas and is = E. debile 

 Lee. 



12. E. villosum (Fabr.) = Stenocorus putator Peck.; $ with 

 5th ventral rounded at tip. 



13. E. parattelum Newman, = arctum Newm., = oblitum 

 Lee. ; with 5th ventral truncate at tip. 



15. E. subpubescens Lee., New Jersey and Texas. The palpi 

 in this species are very unequal, but this character hardly indi- 

 cates a distinct genus. 



49$. E. aculeatum. Valde elougatum, piceo-testacetim, parce 

 longius pnbescens, et pilis volatilibus villosnm, prothoraoe latitudine 

 sesqui longiore, medio paulo latiore, confertim grosse punctato, callo 

 dorsali inconspicuo laevi ; elytris minus dense punctatis, nitidis, apice 

 fortiter bispinosis, spina exteriore elongata ; antennarum articulis 3io 

 et 4to spinis longis, 5to autem brevi armatis. Long. 15 mm. 



One $ , Texas, Dr. Horn. Nearly allied to E. subpubescens 

 Lee., but easily known by the prothorax being less cylindrical, 

 the outer spine of the elytra and the antennal spines much longer, 

 by the flying hairs much longer, and the body beneath coarsely 

 not densely punctured. The hind angles of the metasternum are 

 densely pubescent, the scent pores moderately distinct, and the
