66 Mr. G. C. Champion's Revision of the Mexican 



prothorax at the base, widened towards the apex; closely, very 

 finely punctate. 



(5*. Anterior tarsi with the prolonged upper portion of joint 2 

 rather stout, reaching the apex of 3. 



Length 21 mm. (c^.) 



Eah. Panama, San Lorenzo (Champion). 



One male (somewhat immature), captured in January, 

 1883. ' Recognisable by its very broad, short head, large, 

 prominent eyes, ample prothorax, interruptedly flavo-fas- 

 ciate elytra (the triangular lateral patch extending inwards 

 to near the suture), and shining surface. A. megalops has 

 the elytra marked much as in ^. subfasciatus, Gorh., from 

 Sonora, differing from that insect in its less convex form, 

 broad head and prothorax, more elongate elytra, longer 

 hmbs, etc. 



31. Attalus debilicornis, n. sp. 



Comparatively short, widened posteriorly, shining, the elytra 

 somewhat opalescent; nigro-piceous, the mouth-parts, antennae, 

 front of the head (the pallid coloration limited behind by the an- 

 teriorly bidentate dark portion), the basal margin of the prothorax, 

 a common, post-basal, transverse fascia on the elytra (extending 

 forwards at the sides to beneath the humeri), the apices of the 

 latter, and the trochanters and legs, pale testaceous; sparsely 

 pubescent, and also set with a few dark bristly hairs. Head short, 

 broad, polished, very minutely punctulate, shallowly bifoveate; 

 antennae short, slender, joints 4-10 about as broad as long. Pro- 

 thorax strongly transverse, minutely punctulate. Elytra very 

 little wider than the prothorax at the base, much widened posteriorly, 

 minutely punctate. 



(J. Anterior tarsi with the prolonged upper portion of joint 2 

 stout, nearly reaching the apex of 3. 



Length IJ mm. ( (J.) 



Hab. Guatemala, Capetillo (Champion). 



One male. Closely related to A. anthobioides, Gorh., 

 differing from it in the bifasciate elytra, and the shorter, 

 more feebly developed antennae.
