new Species o/" Histeridse. 81 



The oblique interstitial elytral stria is obliterated in 

 poggei by the rugose sculpture, but it is traceable in singu- 

 laris, Sell., and shows that the inner humeral stria is complete 

 and similar to the stria o£ those species I have assigned to the 

 genus Exorhabdus. The outline of the mesosternura is formed 

 the same in both genera, and they should be placed close 

 together in the Catalogue. The outer humeral stria in 

 poggei extends from the base, where it is carinate, to beyond 

 the middle; in singularis it is wholly carinate but short, 

 ceasing where in poggei it is no longer carinate. 



Macrolister curvistrius, sp. n. 



Ovatus, convexus, niger, nitidus ; labro excavato, emarginato, stria 

 frontali Integra tenuiter impressa; pronoto stria interna hand 

 interrupta; elytris striis 1-3 integris, 4 basi abbreviata apico 

 couspicue sinuata, 5 et suturali obaoletis ; propygidio punctu- 

 lato, margine postice in medio loevi ; pygidio dense punctato ; 

 prosterno baud striate ; mesosterno stria marginali interrupta ; 

 tibiis anticis 3-dentatis.

This species is very similar to laiipes, Palis. Beau v., but 

 the labrum is rather less wide, the inner thoracic stria is 

 complete, not interrupted behind the head, and the outer 

 stria quite reaches the base, the elytral fourth stria is not 

 punctiform, but shortened by about one-third at the base, and 

 posteriorly it is markedly sinuous, the propygidium is much 

 more clearly punctured, with a median smooth space on the 

 posterior border ; the sterna are similar to those of latipes. 

 The thoracic stria being complete is of importance, as the 

 other known species placed in the first section of the genus 

 (in which the mesosternal stria is interrupted) have this stria 

 interrupted. In one specimen I have seen the labrum is 

 impressed, not excavated, and in others the short apical 

 dorsal striae are punctiform.
