Genera and Species of Coleoptera. 349 



phia, although the oldest (1842), is almost unknown to continental 

 entomologists, while Praonetha (1853) seems to be generally adopted, 

 nor am I sure that Pterolophia has not been already used. It is 

 always more difficult to suppress an old genus than to establish a 

 new one. 



Praonetha undulata. 

 P. olivaceo-brunnea ; capite prothoraceque griseo pubescentibus ; elytris 

 subunicostatis, apice truncatis, plaga magna ante medium fasciaque 

 dentata apicem versus albescentibus. 

 Sab. Moluccas (Batchian). 



Pale olive-brown ; the head and protborax sparingly punctured, and 

 covered with a short thin greyish pubescence, the latter about equal 

 in length and breadth ; scutellum transversely subcordate ; elytra 

 slightly compressed posteriorly, a broad but slightly elevated carina 

 near the shoulder, with a very thin greyish pile principally at the base 

 and sides, a large oblique patch before the middle and a very irregular 

 zigzag band behind it white ; mandibles glossy black ; eyes brown ; 

 antennae scarcely so long as the body. Length 8 lines. 



Near P. albosignata, Bl., and, after that, the largest of the genus. 



Praonetha costalis. 



P. rufo-brunnea, pube grisescente varia ; elytris tricostatis, costa interiore 

 basi elevata, apice truncatis. 



Hab. Batchian. 



Pale reddish brown, varied with a greyish pubescence; head and 

 protborax yellowish grey, with small punctures and patches of brown, 

 the latter nearly quadrate, with the sides slightly rounded ; scutellum 

 transverse, rounded behind ; elytra subtrigonate, irregularly and rather 

 sparingly punctured, tricostate, the innermost costa elevated or forming 

 a slight crest at the base, the intermediate one less prominent than the 

 inner or outer, the apex truncate, greyish, a broad but indistinct rufous 

 brown band in the middle ; antennas longer than the body, rufous 

 brown; eyes brown; legs obscurely varied with greyish; body be- 

 neath didl rufous brown. Length 5 lines. 



The abdomen, in my example, is exceedingly small and contracted. 



Praonetha penicillata. 

 P. pallide brunnea, obscure griseo varia ; elytris basi subcristatis, postice 



fasciculatis, apice rotundatis. 

 Hab. Cambodia. 



Pale brown, obscurely varied or clouded with grey ; head and pro- 

 thorax of a nearly uniform grey, finely punctured, the latter subqua- 

 drate ; scutellum slightly transverse, rounded behind ; elytra subtri- 

 gonate, seriate-punctate, slightly crested at the base, the apex rounded,
