translucent spaces of the thorax it ought rather to be placed in the 

 genus Diaphanes. The thorax is shorter and has the hind angles 

 less produced than is usual in this genus ; the apical ventral plate 

 and the pygidium are yellow; the head, breast, and the extreme 

 base of the legs are yellow, but clouded in parts with fuscous. 

 One specimen.

[Eeceived December 23, 1891.] 



In the following paper the Coleoptera of the families Cleridse, 

 Bostrychidse, Chrysomelidae, Galerucidse, Cassidse, Hispidse, 

 Erotylidse, and Ccccinellidse collected by Mr. W. Bonny during the 

 Emin Relief Expedition are noticed and the presumed new species are 

 described, in continuation of the accounts already furnished by 

 Mr. Bates (P. Z. S, 1890, pp. 479-492, and Mr. Champion, pp. 637- 

 646). The species of which examples were represented were not 

 numerous, but the same remarkable coincidence specifically with the 

 Coleoptera of the West Coast, especially of Old Calabar, will be 

 noticed. 



The Phytophaga, with the exception of the Cassidae and Hispidae, 

 have been kindly worked out by Mr. Gahan of the British Museum.
