Not uncommon on the banks of the Zaire. 



This may be the Trichius barhatus of Afzehus. As the speci- 

 mens agree closely with the male collected by Mr. Cranch and 

 described by MacLeay from the example in the British Museum, 

 I give his name : this is the insect alluded to by Dr. Leach in the 

 Appendix to Tuckey's Narrative (p. 41 8) as " a new genus of the 

 family Scarahceidea." I am inclined to think there may be three 

 species of Platygenia. 



Amongst the Buprestida occur two apparently undescribed spe- 

 cies of the genus Sternocera, Eschscholtz. Of a species nearly 

 allied to one of these, two specimens already exist in om* collec- 

 tion, brought by Dr. Burchell from S. Africa, to which the MS. 

 name of Buprestis liturata has been applied by that enterprising 

 and learned traveller. The following specific character may di- 

 stinguish it from the Sternocera interrupta ; it is, like all its con- 

 geners, variable in size ; the least specimen is 1 inch 5^ Hues, the 

 largest I inch 7 lines. 



The thorax is more coarsely punctured than in S. interrupta, 

 and not so much so as in S. castanea ; the abdomen beneath has also 

 only a few slight hairs on its general surface, and the fom* last 

 segments have on each side, between the side and middle, a patch of 

 close-set hairs ; that on the anal segment elongated. In Dr. Bur- 

 chell's S. liturata the elytra are differently sculptm'ed, showing 

 symptoms of ridges ; the spots are smaller, especially the hind 

 ones. My species may tui'n out a local variety of this ; meanwhile 

 I describe it as 



Sternocera liturata (var. Currori). St. eenescenti-nigra, thoracis la- 

 teribus singulis plaga magna depressa tomentosa (sub pilis super-
