CERAMBYCID^E 305 



obsoletiis Thorns., but on reading Mr. Bates' description of that 

 form, I have no hesitation in announcing it as distinct; the posterior 

 fascia is obsolete in obsoletus but is very pronounced in procerus. 



Glaucotes n. gen. 



The type of this proposed genus is Leptostylus yuccavorus Fall, 

 from southern Arizona; it differs from Leptostylus in the smooth 

 surface of the elytra, varied only by three very even and feebly 

 elevated discal costules, more densely pubescent, vanishing basally 

 and wholly devoid of clustered erect hairs of any kind ; it also differs 

 from any form of true Leptostylus in the rounded and not truncate 

 elytral apices. Its general habitus is very different from any 

 Leptostylus, although apparently not distinguished by structural 

 peculiarities other than those mentioned. There are probably 

 several species of Glaucotes, judging by my material. 



Leptostylus Lee. 



This is a very large and, as organized at present, not very sharply 

 limited genus, of wide distribution in the North and South American 

 continents; in the rather stout, roughly sculptured body it is some- 

 what intermediate between Lagochirus and the Leiopi. In this 

 country it is most abundantly represented in Florida. The fol- 

 lowing apparently new species have come to light more or less 

 recently : 



Leptostylus lecontei n. sp. Moderately stout, dark brown, clothed 

 densely with luteo-cinereous vestiture, mottled with paler and darker 

 areas; front between the eyes before the antennal prominences much 

 wider than long; antennae (9) mottled, a third longer than the body; 

 prothorax four-fifths wider than long, nearly as wide at apex as at base, 

 the prominences moderate, broadly rounded; surface with a few small 

 widely scattered punctures and more in transverse line at apex and base, 

 also with five moderate tubercles, the vestiture uniform; elytra three- 

 fifths longer than wide, much wider than the prothorax, the sides ar- 

 cuately rounding, more so apically, to the transversely and sharply 

 truncate apices, the humeri rather prominent; surface with small sparse 

 penicillate black warts, some of which are on an oblique discal raised line 

 at outer third, also darker in a large post-humeral lateral area, extending 

 to the middle and obliquely truncate internally somewhat on the disk; 

 also a fine oblique line on each just behind the middle, meeting the other 

 on the suture and before which, and between it and the lateral dark area, 

 the vestiture is whiter; also with two small dark, and two or three paler,
