new Species of Histeridse. 269 



Apobletes cavifrons. 



Ovalis, planatus, niger, nitidus ; fronte excavafca, stria transversa 

 nulla, mandibulis distincte punctatis ; pronoto lateribus rugose 

 punctato, stria marginali post caput interrupta ; elytris striis 

 1-3 integris, 4 apicali ; pygidio dense et fortiter punctato. 



L. 3|-3f mill. 



Oval, flat, black and shining ; the head, forehead excavated 

 and evenly, not closely, punctured, the stria over the eyes is 

 strong and bent, there is no transverse stria, but the suture 

 dividing the forehead and the epistoma is straight and clear ; 

 the labrum is punctured like the forehead and is minutely 

 strigose at the base; the mandibles are densely and rather 

 rugosely punctured; the thorax, marginal stria strong laterally, 

 but fine behind the head, and it does not meet in the middle, 

 lateral borders are rugosely and densely punctured, especially 

 behind the anterior angles ; the elytra, the outer humeral 

 stria is wide, basal, and dimidiate, inner humeral is wanting, 

 oblique basal fine but clear, 1-3 dorsal complete, 4 apical 

 and very short. The elytra, striaa are almost similar to those 

 of A. Sckaumi, Mars., and also closely similar to those of 

 A. tener, Mars., but in the last the third dorsal stria is inter- 

 rupted in the middle. The propygidium is somewhat impressed 

 and punctate on either side, with the middle and posterior 

 border smooth ; the pygidium is deeply punctate, punctures 

 clear and of equal size, set close together, the posterior margin 

 is slightly elevated ; the presternum, the anterior lobe is 

 marginate, and in this and other respects it is similar to that 

 in A. tener; the mesosternum also resembles that of A. tener , 

 but the anterior border is more distinctly bisinuous ; the 

 anterior tibiae are 4-5-dentate. 



This is a very distinct species, but resembles the species 

 named superficially. 



Hab. Patkai Mountains, Assam (Doherty). 



Apobletes macilentus, sp. n. 



Oblongo-ovatus, parallelus, depressus ; fronte sat dense punctulata ; 

 pronoto lateribus punctulato, stria integra ; elytris striis 1-3 

 integris, 4 apicali ; pygidio subconvexo, dense punctato. 



L. 2f-3 mill. 



A. macilentus differs from A. nirvana, Lew., in being 

 smaller, more depressed and more parallel laterally, the head 

 and thoracic borders are much less distinctly punctured, the 

 elytral striae are finer and nearer to each other, the fourth stria 

 is short and apical and the fifth is either wholly wanting or
