COLEOPTERA 381 



(31) Eopcnthcs paii'itlits, sp. nov. 



Rufulus, capite nigro : elytris pallidis, subtiliter striatis, strils ad apicem perparum 

 impressis ; tarsis articulis bene dilatatis, articulo quarto minuto. Long. 6 mm. 



This is one of tlie smallest Eopenthes. We have only 6 specimens ; they are all 

 females, and are distinguished from E. dehilis by the rather smaller size, and the more 

 delicate striation of the elytra. The distinctness of the species requires confirmation 

 by comparison of larger series of the two forms.

(32) Eopenthes marginains, sp. nov. 



$ Niger, elytris pallidis, nigro-marginatis, antennis pedibusque fusco-testaceis ; pro- 

 thorace crebrius fortiter punctato, elytris striatis, striis apicem versus obsoletis. Long. 

 5^ mm. 



This is the smallest of the Eopenthes. We have only one specimen ; it is a male, 

 and comes very near E. pai\<iilus, though extremely difterent in colour. Uur specimens 

 of E. panmlns are all females, and E. niarginatns therefore is at present a doubtful 

 species. It may prove to be a variety of the male of E. parvulus. The elytra are very 

 pallid with the suture and the extreme tips black, and the black colour extends forwards 

 along the extreme outer margin ; the extreme base of the elytra is also black. The 

 interstices ot the elytra are very narrow, and the apices are very attenuate.

{t^'},) Eopenthes tarsa/is, sp. nov. 



? Niger, pedibus flavis, elytro singulo plaga magna pallida, antennis fusco-flavis. 

 Long. 8^, lat. 2 mm. 



This species is very readily recognisable by the remarkably definite coloration and 

 the fact that the dilatation of the tarsi here reaches its maximum. We have only one 

 female. The form is rather elongate and parallel ; the thorax is rather closely and 

 coarsely punctured. The elytra have a black triangle at the base, the apical portion 

 is broadly black, and the suture and side-margins narrowly black. L^nderneath the 

 colour is intensely black : the legs are yellow. The dilatation of the tarsi is as well 

 marked in the hind as it is in the front pair.
