new Species of HUteridse. 87 



co\a?, near which, ou either side, is a small but distinct 

 puncture or fovea ; the mesosteruuui is margiuate and bi- 

 sinuous. 



Resembles P. formosus, Sch., and cregoei^ Lew., but it 

 differs by the fine punctuation of the head, deeper dorsal 

 striae (which liave no specially wide interstice), and by 

 the interrupted prosternal striffi and fovea. P. formosus and 

 cregoei have the head more distinctly punctured and the 

 sternal striie are similar in both species. 



Hub. Bolama, Portuguese Guinea. 



Pehrurus pumicatus, sp. n. 



Brevitcr ovalis, supra depressus, nigro-cupreus ; elytris obacure 

 viridi-caerideis ; fronte tenuiter impressa, leviter punctulata ; 

 pronoto lateribu? sat fortitcr punctato ; elytris striis 1-2 gemi- 

 natis integris, 3-4 posticis geminatis, 5 apicali, sucurali integra 

 baud geminata ; tibiis anticis denticulatis. 



L. 5| mill. 



Shortly oval, somewhat depressed above, thorax coppery, 

 elytra somewhat obscurely greenish blue ; the head lit^htly 

 impressed behind the clypeus, surface very lightly and finely 

 punctulate; the thorax somewhat coarsely punctured laterally, 

 with a line of irregular points at the base before the scutel- 

 lum ; the elytra, inner subhumeral stria is broken or 

 punctiform, and shortened at the base, 1-2 dorsal complete 

 and geminate, 3 geminate only in the posterior half, 4 double, 

 but apical only, 5 is single, short, and apical, with basal 

 puncture as an appendage, sutural single, very slightly 

 shortened at the base and approaches the suture posteriorly ; 

 the propygidium is clearly, eveulv, and rather densely 

 punctate ; the pygidium has a few irregular fine points ; 

 the prosternum, the striae are fine and not very clearly 

 impressed and the marginal stria of the mesosternum is 

 similar ; anterior tibiae denticulate. 



The very fine punctulation on the head, the thoracic line 

 of punctures before the scutellum, and the form of the 

 elytral striae distinguish this species from its congeners. 



Hab. Harrar, Abyssinia. 



Microchates costatiiSy Macleay, 1871. 



Lea states that the above, Trans. Ent. Soc. Lond, p. 145, 

 1907, is identical with Epiechinus tasmani, Lew., 1899. 

 Macleay confused the Histeridae with theByrrhidae, describing 

 one as a Limnichus and the above as a Microchcetes. 

 Macleay's specific name has precedence to mine.
