16 Mr. G. Lewis on 



approaching in fact the form in the genus Contipus] hut it 

 is a Hister of the American type, whicli includes Hister cavi- 

 frons and iinpressifrons of Marseuh It is the only species of 

 Ulster at present known with a bluish tint on the elytra. 



Flah. Santarem and Benevides {H. H. Smith). Twelve 

 examples. 



IHster striatipectus, sp. n. 



Breviter oralis, subconvexus, niger, iiitidus : fronte levitcr impressa ; 

 pronoto stria laterali interna integra ; el^tris striis 1-2 integris, 

 3 intorrupta, 4-5 brevissimis, suturali utrinque abbreviata ; pro- 

 pvgidio j)ygidioqixe grosse punctatis : prosterno bistriato. 



L. 5| mill. 



Shortly ovalj rather convex^ black and shining ; the head 

 feebly im])vessed, stria complete, bisinuous anteriorly and 

 sulcata over the eyes; the thorax, inner lateral stria deep, 

 shortened just before the base and continued behind the head, 

 very feebly sinuous behind the eyes, outer stria short and 

 confined to the region of the angle, marginal very tine and 

 ceasing behind the eye; the elytra, stride, inner humeral tine, 

 oblique and basal, outer wanting, dorsal 1-2 complete and 

 deep, .3 basal, dimidiate, with a siiort apical appendage, 4-5 

 very short and apical, sutural dorsal, much shortened ante- 

 riorly, rather less so behind ; the propygidium and pygidium 

 are very coarsely punctate, punctures close but not dense, the 

 punctures are larger than those of H. coroyiatus, Mars., and 

 more closely set ; the prosternum is remarkable, it is bordered 

 by a very tine but clear stria, wdiich continues along the base, 

 but anteriorly stops at the suture without turning inwards ; 

 the mcsosternum is widely sinuous in front, marginal stria 

 complete but abruptly ending before the metasternal suture ; 

 the nietasternum, lateral stria fine and continued along the 

 anterior suture, being rounded oflf on either side, not angu- 

 late ; the tibiie, anterior apically bifid, with four small teeth 

 behind them, hinder tibia? somewhat dilated, tarsi short. 



This species should be placed next to //. Sallet, Mars. In 

 B. Sallei the punctuation of the pygidium is not nearly so 

 coarse, the prosternal striai are similar but do not reach the 

 anterior suture, and the metasternal transverse stria is 

 distinctly crenulate and angulate on either side.
