67. I(. igiiava n. sp. — Oblong, cylindrical, chestnut-brown, shining. Head 

 broad, eyes moderately prominent. Clypeus fiat, feebly emarginate, the border 

 very narrowly reflexed, surface densely and rather coarsely punctate, front 

 similar. Thorax rather short, very little narrower at apex than at base, sides 

 arcuate, margin coarsely creiiate, surface with rather coarse, subvariolate punc- 

 tures closely, but somewhat irregularly placed. Elytra parallel, not wider than 

 the thorax, jiunctures as coarse as on the thorax and moderately closely placed, 

 less deeply impressed near the apex, sutural costa rather feeble, the discal costie 

 indistinct, the submarginal feeble near the apex. Pygidium coarsely sparsely 

 punctate. Metasterimm closely punctate, the hair moderate in length, not dense. 

 Abdomen sparsely rather finely punctate, without hair. Claws feebly curved, a 

 moderate tooth at middle. Last joint of maxillary palpi moderate in length, 

 slightly flattened externally. Length .60 — .65 inch ; 15 — 16.5 mm. 



Male. — Club of antenna a little shorter tlnui the entire stem. 

 Abdomen without characters. 



Female. — Club shorter than the funiculus. Posterior tarsi a very 

 little shorter than in the male, the pygidium a little longer. 



Variations. — About a dozen specimens have been seen in various 

 collections without variation, except slightly in color. 



This species and hoops are more nearly truly cylindrical than any 

 others in our fauna. It is also one of the few with absolutely no 

 sexual differences in the abdomen. 



Occurs in Texas and New Mexico (Prof. Snow). 



The following species should })robably be referred to this group if 

 it really is a member of our fauna. The description is from Blanch- 

 ard supplemented by notes taken by myself from the type : 



68. L<. long^icornis Blanch. — Oblong, nearly parallel, subcylindrical, brown, 

 shining, slightly paler beneath, glabrous. Clypeus feebly emarginate ("integer" 

 Bl.) and with the front densely punctured. Thoi'ax with feebly arcuate sides, 

 the margin crenulate, surface densely punctured and with a pseudo-strigose ap- 

 pearance. Elytra moderately punctate, the costfe very indistinct. Pygidium 

 finely punctate. Legs somewhat reddish. Metasternum with pale hairs. Claws 

 with a small tooth slightly in front of the middle. Length 18 — 19 mm. 



M.\LE. — Antennal club longer than the stem. Abdomen vaguely 

 impressed at middle, the last two segments without sexual characters. 



The locality is indefinitely given as " Amer. Bor." Du voyage de 

 M. de Castelnau. 



Two reasons have caused me to doubt that this species belongs to 

 our fauna. First, nearly all the species given by Castelnau described 

 in Blanchard's catalogue are from Brazil; secondly, the tooth of the 

 claw is small and in front of the middle, a character entirely unknown 

 in our large series of species.
