Longicorn Coleoptcra of Chontales. 229 



third as in most cases, the apical portion being indicated 

 in outline, but of a brown colour; it does not reach the 

 base, or sides, and is emarginated laterally, about the 

 middle, by a broad lobe of the dark-brown marginal 

 colour. The apex of the elytra is truncated, with the 

 sutm-al angle acute and slightly produced, the exterior 

 angle prolonged into a sharp spine. The long, clavate 

 femora have a fulgiu:ated gray mark.

Agrees with Mexican specimens, which I believe are 

 correctly referable to this species. 



Le-ptostylus palUatus, n, sp. Oblongus, fuscus, capite 

 thoraceque ochraceo-cinereis, elytris albo-cinereis, maculi 

 apicali magna atro-fusca antice undata, setisque cinereis 

 seriatim ordinatis. Long. 5 lin. 



One example. 



Similar in shape, degree of convexity and colour to 

 L. transversus (Gyll.), but the surface smooth and not 

 tuberculated, and the dark apical patch of the elytra 

 having its anterior margin sharply undulated. The head 

 and thorax are very smoothly and thickly clothed with 

 laid ochreous-ashy pile, so that scarcely any punctuation 

 is visible and no tubercular elevations, the lateral tubercles 

 being obtuse and the base slightly depressed and con- 

 stricted. The elytra are gradually declivous and narrowed 

 towards the apex, wliich is narrow and obliquely and 

 sharply truncated; the surface is smooth and furnished 

 Avith rows of short, stiff whitish bristles springing from 

 raised lines; two-thirds of the surface is whitish-ashy, 

 and this colour is sharply separated from the dark apex by 

 a line of whiter colour, a narrow stripe of broMTi extending 

 on each side fi'om the shoulder but scarcely protruding on 

 the white dorsal surface. The antenna are brown and 

 speckled ; the apical joints ringed with ashy.

 hand productis ; elytris fasciculis acumiuatis setarum seri-
