DESCRIPTIONS OP NEW SPECIES. .185 



legs coarsely punctured. The ventral segments diminish rapidly 

 in length, and the 5th joint is broadly truncate. 



17. E. unicolor ; Stenocorus un. Randall, Stizocera un. Hald., 

 Psyrassa un. Pascoe. I can find no sufficient characters for 

 separating this as a distinct genus, much less placing it in 

 another tribe. 



499. E. mmctatum. Elongatum piceum, fortiter punctatum, pilis 

 longiusculis griseis parce vestitum, prothorace latitudine longiore, linea 

 dorsali laevi calloque elongate indistincto utrinque notato ; elytris paral- 

 lelis, apice rotundatis haud spinosis, scutello luteo-pubescente ; palpis 

 antennis pedibusque ferrugineis, pube subtili pallida vestitis, his vix 

 punctulatis, pilis volatilibus elongatis sat numerosis, antennis haud 

 spiuosis ; metasterno poris odoriferis nullis. Long. 10 12 mm. 



Two females, Cape San Lucas, Lower California; Mr. Xantus. 

 The body beneath is finely punctulate and pubescent, with longer 

 hairs intermixed. The general form is as slender as in E. 

 parallelum. 



19. E. cinerascens Lee., Anoplium unicolor || Hald.; with 

 5th ventral emarginate, leaving the 6th visible. Placed by 

 Lacordaire in his group Callidiopsides, but I can see no reason 

 for separating it so widely from Elaphidion, to which it is evi- 

 dently most closely related. 



ANEFLIJS LEC. 



This genus is rendered necessary for certain species which 

 completely resemble the elongate forms of Elaphidion, (subpu- 

 bescens, etc.), in appearance, sculpture, and pubescence, but 

 differ by having the joints of the antennae from the 5th flattened, 

 and distinctly carinate along the middle of the flat sides. The 

 legs are coarsely punctured and pubescent, the tibise are finely 

 carinate, but not more distinctly than in many species of Elaphi- 

 dion, and except in E. tenue, the carinae are not visible on the 

 hind pair ; the spurs are well developed. The 1st ventral is 

 evidently longer than the others, and the 5th in $ is broadly 

 emarginate. 



The species may be tabulated as follows : 



A. Prothorax distinctly dilated and feebly angulated on the sides ; elytra 

 bispinose at tip; hind tibiae scarcely carinate; palpi unequal, with 

 the last joint dilated triangular ; 



Very large, spines of antennae moderately long. 1. PROTENSUS.
