mit a first instalment relating to the Family Pentatomidæ, which 
was so numerous in species as to comprise about half of the whole 
collection. 
The material has been derived from the following localities : 
Gabon and its vicinity . Mons. J. Carradot. 
Congo. . . . . . Capt. Van Gele and M. V. Moerenhout. 
Lankoungou . . . . Lieut. Franqui. 
Niam-Niam . . . . Herr Bohndorff. 
The collections from the three first named localities are small, 
but the largest and most important is that from Niam-Niam, an 
entomological region of which we pratically knew nothing. Of the 
Rhynchota of Niam-Niam we may affirm that its relationship is 
with that of Western Africa, but with a very large proportion of 
distinctive specific characters. 
The remainder of the collection will be enumerated and des- 
cribed in a subsequent paper, and I have given a complete list of 
the species with their habitats, as the geographical distribution 
of tropical African species is a knowledge much to be desiderated 
and at present little known.
