new Species of Histeridse. 85 



interstices are obscurely reddish, the other dorsal atrial are 

 wanting ; the propygidium is transversely punctured along 

 its basal half, the posterior half is smooth ; the pygidium is 

 reddish, convex and oblong, it is twice as long as broad and 

 irnpunctate ; the prosternum, keel is very narrow and smooth 

 and acuminate anteriorly ; the mesosternum has two patches 

 of ferruginous bristles, well separated from each other, on 

 its posterior border; the first segment of the abdomen has a 

 punctate stria along its posterior margin ; the legs, the tibiaj 

 are a little dilated with fine bristles on the outer edges, which 

 are bowed, not angulate, the tarsal grooves are nearly straight, 

 and the upper surfaces of all the tibiee are finely and closely 

 puncticulate.

Type in the British Museum. 



Iletcerius carinistrius, sp. n. 



Breviter ovatus, nitidus, piceo-brunneus, supra setosus ; front o 

 impressa, dense puncticulata, raargine elevata; pronoto trans- 

 verso, margine laterali late incrassato ; elytris striis 1-2 integris, 

 basi carinatis, 3-4 apice abbreviates, basi leviter carinatis, mar- 

 gine postice minute rugosis ; propygidio parum dense puncticu- 

 latis ; tibiis angulato-dilatatis. 



L. 2 mill. 



Shortly oval, pitchy brown, setose ; the forehead opaque 

 and densely puncticulate, edges elevated ; the thorax is trans- 

 verse, with an oblique lateral sulcus and a broad thickened 

 margin punctured and a little opaque, broadest anteriorly and 

 slightly sinuous on its outer edge before the base, at the base 

 there is a small elongate elevation and within the sulcus is a 

 basal fovea, the disc is smooth ; the elytra, first dorsal stria 

 is complete and distinctly carinate, especially at the base, 

 second complete but less carinate and only at the base, third 

 and fourth striae are shortened apically and again art; less 

 carinate, the apical margin is narrowly and finely rugose ; 

 the propygidium is reddish and finely but rather densely 

 punctulate ; the pygidium is almost smooth, with a micro- 

 scopic strigosity at the apex, reddish ; the prosternum, striae 

 widen out at the base and are sinuous before the coxaa, and 

 do not meet anteriorly, being lost in the dense rugosity of the 

 anterior surface of the keel, the sculpture of the keel gradually 

 lessens in density to the base ; the mesosternal foveae are 

 deep ; the tibiae are dilated, especially the intermediate and
