DYNASTIN/E 207 



and finely, closely rugose, the extreme base smooth; carina long, 

 entire, sharply and strongly elevated, not attaining the sides though 

 joined to the sides by a feeble supplementary ridge; clypeus concave 

 and finely rugose, almost exactly as in gibbosus, the denticles very 

 small, approximate and spinuliform; prothorax two-thirds or more 

 wider than long, the sides almost evenly arcuate, strongly con- 

 verging at apex, the punctures sparse but strong and impressed; 

 scutellum wider than long, nearly smooth, ogival; elytra barely 

 visibly longer than wide, rapidly very broadly and obtusely rounded 

 at apex, at apical third much wider than the prothorax, about twice 

 as long; punctures fine, sparse, arranged as in the preceding, more 

 close-set in the double series; pygidium polished, finely, remotely 

 punctate; hind tibiae notably slender, fully as long as the femora 

 and much longer than the tarsi, which are unusually short relatively. 

 Length (cf 1 9) 15.0-16.5 mm.; width 8.7-9.8 mm. Honduras (San 

 Pedro Sula). Three examples. [Podalgus nasutus Burm.] 



*nasutus Burm. 



Pronotum tumid along the median line apically. Body more oblong, 

 parallel and less abbreviated, more convex, smooth and shining, 

 blackish-brown, obscure rufous beneath and with long dense con- 

 spicuous sternal vestiture, the femora brighter rufous; head small, 

 but little more than a third as wide as the prothorax, the front 

 evenly and feebly convex and with widely separated short transverse 

 rugulosities, the carina completely though narrowly interrupted at 

 the middle, the ridges fine, rather elevated and completely fused 

 with the side margins; clypeus finely, more closely and granularly 

 rugulose, of the usual form but with the apex more broadly obtuse 

 than in nasutus or gibbosus and with two small, erect and rather 

 approximate denticles; mandibles as in gibbosus; mentum of the 

 usual form, punctate and setose throughout; prothorax exactly as 

 in the preceding but rather more narrowed at apex, smooth, ex- 

 tremely finely, sparsely and feebly punctulate, the punctures rather 

 abruptly distinct and closer near the sides; scutellum barely wider 

 than long, smooth, very acutely ogival; elytra not quite a fourth 

 longer than wide, parallel, faintly dilated behind the middle, circu- 

 larly rounded in about apical third, nearly a fifth wider than the 

 prothorax and much more than twice as long; punctures very sparse, 

 fine and feeble but arranged nearly as in the preceding; pygidium 

 with the punctures rather larger and more close-set than those of 

 the elytra but extremely feeble and shallow, almost wanting medially; 

 hind tibiae rather stout and apically, strongly flaring, fully as long 

 as the femora and distinctly longer than the tarsi. Length (9) 

 17.5 mm.; width 9.7 mm. Chile. [Podalgus lillosus Burm.] 



*villosus Burm. 



In both nasutus and villosus the maxillary galea is clearly tri- 

 dentate as in normal Ligyrus, but in my single example of fossor 

 the galea is not exposed to view. The prominent surface of the 

 pronotum toward the middle apically in villosus, is an opposite
