approaching in fact the form in the genus Contipus ; but it 

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

 frons and impressi/rons of Marseul. It is the only species of 

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



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

 examples. 



Ulster striatipectuSy sp. n. 



Breviter ovalis, subconvexus, niger, nitidus ; fronte leviter impressa : 

 pronoto stria lateral! interna Integra; elytris striis 1-2 integris, 

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

 pygidio pygidioque grosse punctatis ; prosterno bistriato. 



L. 5| mill. 



Shortly oval, rather convex, black and shining ; the head 

 feebly impressed, stria complete, bisinuous anteriorly and 

 sulcate 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 fine and 

 ceasing behind the eye; the elytra, striae, inner humeral fine, 

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

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

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

 riorly, rather less so behind ; the propygidium and pygidium 

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

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

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

 by a very fine but clear stria, which continues along the base, 

 but anteriorly stops at the suture without turning inwards ; 

 the mesosternum is widely sinuous in front, marginal stria 

 complete but abruptly ending before the metasternal suture ; 

 the metasternum, lateral stria fine and continued along the 

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

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

 behind them, hinder tibiee somewhat dilated, tarsi short. 



This species should be placed next to H. Sallei, Mars. In 

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

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

 anterior suture, and the metasternal transverse stria is 

 distinctly crenulate and angulate on either side.
