Species rt/'Histerida?. 471 



striis subparallelia ; mesosterno in medio acuminato marginato, 

 stria transversa terminato : metasterno punctato, linea in medio ; 

 pygidio tenuissime strigoso-rugoso, pnnctato. L. 3^- mill. 



Hah. Abyssinia (Bo fray). 



This is near parasita, but is more cylindrical and more elon- 

 gate. The punctuation is more general, the marginal strias 

 of the prosternum are more parallel and only slightly divergent 

 in front. A transverse line divides the meso- from the meta- 

 sternum, and in this and in the wide interstice of the thoracic 

 margin it agrees with picijpes. The pygidium under the 

 microscope is very finely strigosely rugose between the rather 

 large punctures. 



Teretrius brunneiis, Lewis, 1879 —pidex, Fairm. 1877. I 

 am enabled to determine the synonymy of the above through 

 the kindness of Mons. R. Oberthiir, who has sent me a type 

 of pulex. 



Homalopygus commensalis, n. sp. 



Oblongo-ovatus, subconvexus, piceus, nitidus ; antennis pedibusque 

 rufo-brunneis ; fronte dense subocellato-punctata, stria utriuque 

 sat distincta ; pronoto antice subocellato-punctato, postice punc- 

 tato, stria interna integra, media in angnlo cessante : elytris 

 undique punctulatis, striis 2 et 3 dorsalibus integris, 1 et 4 basa- 

 libus brevibus, suturali basi et apice interrupta ; propygidio pygi- 

 dioquc punctulatis ; prostcrno lateraliter marginato ; mesosterno 

 stria integra. L. 2- 1 - mill. 



This species is less wide and more convex than longipes y 

 and the thoracic and elytral stride, which are short or nearly 

 obsolete in the latter, are long and well defined in commen- 

 salis. 



Hah. Blumenau, Brazil, and has been found, Herr E. 

 Reitter informs me, in the galleries made by Termites.
