Heteronydviis fovcipennis, Fairm., may be placed in the 

 genus Anodon. It is probably not distinct from Londwtm 

 niuticus, Burm. In addition to the last misplaced species, 

 only three species of Lonchotus have been described, 

 although they appear to be rather numerous. Two, which 

 are represented in the Museum by series consisting of 

 both sexes, are described here. 



Lonchotus punctatissimus, sp. n. 



Niger, vel nigro-piceus, convexus, modice elongatus, capite crebre 

 rugoso, antice minute hand acute bidentato ; protborace baseoa medio 

 excepto dense punctate ; scutello impunctato ; elytris stria suturali 

 crenata completa lineisque sex postice abbreviatis punctarum ocella- 

 tarum, pimctis magnis crebris, externis magis irregularibus, intersti- 

 tiis alternis punctis nonnullis, sculpturatis, lateribus lasvibus, 

 apicibus modice baud profunde punctatis ; propygidio subtilissime 

 transversim strigoso, pygidio sat minute punctate, apice fere lajvi ; 

 metasterno creberrime rugoso et rufo-birto : 



^ , breviter acute cornuto, cornu recurvato ; protborace profunde 

 sat anguate excavato, fossoe lateribus acute carinatis, antice et post 

 medium utrinque obtuse dentatis, fundo undique transverse 

 ruguloso. 



Long. 25-27 mm. Lat. max. 14-15 mm.

This closely resembles Z. lentus, Burm., but is larger 

 and differs by the distinctly bidentate clyjaeus, more 

 rugose head, and much more strongly and closely punctured 

 pronotum, the excavation of which in the male is a little 

 broader. The puncturation of the elytra is very similar, 

 but rather more distinctly linear. The most strongly 

 marked difference is to be found in the stridulating surface 

 of the propygidium, which in L. lentus is comparatively 

 coarse and in the present species is extremely fine. 



Lonchotus politus, sp. n. 



Niger, nitidus, convexus, sat breviter ovatus, capite dense punctate, 

 antice obtuse acuminate ; protborace punctate, postice medio fere 

 Isevi ; scutello impunctato ; elytrorum parte antica late baud 

 profunde punctata, stria suturali antice obsoleta, apicibus leviter 

 punctatis, aliis locis Isevibus ; propygidio subtilissime transversim
