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



6. On some Coleoptera from Eastern Equatorial Africa, 

 received from Emin Pasha. By Charles O. Water- 

 house, F.E.S. 



[Eeceived 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 Atiica only, as indicated in the following list. The localities 

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



1. Tefflus HAcauARDX, Chaudoir. Zanzibar. 



2. Tefflus carinatus, Klug. Mozambique. 



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



A single male example which agrees well with one from Egypt 

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

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

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

 Africa placed to it. Scarabcevs 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 Scarabaus 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. CoRYPUocERA africana, Drury. W. Africa. 



5. Sternocera klugii, Thomson. Nubia. 



(). Tetralobus subsUlcatus, Guerin. Abyssinia. 



7. Tetralobus dufouri, Candeze. Senegal. 



8. Tetralobus cribricollis, n. sp. 



Piceo-iiiger, parum nitidus, subtililer ffiiseo-pubesccns ; capitis 

 /route antice modice angustata, medio fovea elovgata impressa, 

 vcrtice carina brevimunito; thorace nigra, bene convcxo, confertim 

 sat foriiter rvgoso-pvnctaio ; elytris creberrime subtiiiter punc- 

 tatis, striis dorsaiilus obsoletis, striis duabtis ubbreviatis prope 

 humeros distinctis. 

 Long. 13-1G|, lat 4|-5| lin. 



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

 thorax rugosely })unctured. Frontal plate distinctly narrowed in 



'^ C. cribricoUis, Walker, placed as a synonym of C. sahcens iu Geuuuinger's 

 Catalogue, differs from tliat species in being less .shining and ju Laving only the 

 outer half of the anterior angles of ihe thorax punctured.
