b6 ON COLEOPTKRA FROM EQUATORIAL AFRICA. [Jan. 17, 



6. On some Coleoptera from Eastern Equatorial Africa, 

 received from Emin Pasha. By Charles O. Water- 

 house, F.E.S. 



[Received January 6, 1888.] 



The small series of Coleoptera received from Emin Pasha is inter- 

 esting as containing examples of one species new to science, and of 

 six which had })reviously been received at the British Museum, from 

 West Afiica only, as indicated in the following list. The localities 

 from whicli the other species have been recorded are also here given, 



1. Tefflus hacquardi, Chaudoir. Zanzibar. 



2. Tefflus carinatus, Klug. Mozambique. 



3. Catharsius SESosTRis, Dej. {in Hit.). Egypt. 



A single male example which agrees well with one from Egypt 

 from Dejean's collection and labelled by him ' sesnstris.' 0. sesostris, 

 Dej., according to Gemminger and Harold's Catalogue of Coleoptera, 

 is the same as C. pithecius, Fabr., and has the habitat Tropical 

 Africa placed to it. Scarabceus pithecius, Fabr. (Syst. Ent. p. 21), 

 however, is an Indian species (as Fabricius correctly states), and the 

 type in the Biitish Museum collection is simply an immature spe- 

 cimen of ScarabcEus sabceus, Fabr. (Spec. Ins. i. p. 23), the type of 

 which is also in the British Museum. 



The African species differs from the true sabceus in having the 

 sides of the thorax less rounded anteriorly, and the anterior angles 

 are punctured all over, whereas in C. sabceus they are impunctate\ 



4. CoRYPHOCERA africaNa, Drury. W. Africa. 



5. Sternocera klugii, Thomson. Nubia. 



6. Tetralobus subsXjlcatus, Guerin. Abyssinia. 



7. Tetralobus dufouri, Candeze. SenegaL 



8. Tetralobus cribricollis, n. sp. 



Piceo-niger, parum nitidus, subtiliter griseo-pulescens ; capitis 

 Jronte antice modice aiigustata, medio fovea elongata impressa, 

 vei'lice carina breviniunito; thorace niyro, bene convexo, confertim 

 sat fortiter rvgoso-jmnctafo ; elytris creberrime subtiliter punc- 

 tatis, striis dorsaiilus obsoletis, striis duabus abbreviatis prope 

 humeros distinctis. 

 Long. 13-16|, lat 4^-5^ lin. 



Allied to T. rotuniJifrons, but narrower, less shining, and with the 

 thorax rugosely punctured. Frontal plate distinctly narrowed in 



^ C. cribricollis, Walker, placed as a synonym of C. sabceus in Geniminger's 

 Catalogue, differs from tliat species in being less shining and in having only the 

 outer half of the antcnor angles of the thorax punctured.
