shorter in the middle than at the sides, its length at the 
former point being about equal to that of 3 or 4. Legs 
rather short and stout; tibize with a sharp mucro, the 
corbels of the hind pair open and bare; the claws connate. 
All the specimens examined appear to be females. 
Genotype, Strophosomus granicollis, Boh. 
Thanks to the kindness of Prof. E. B. Poulton, F.R.S., 
I have been able to examine the cotypes of S. granicollis, 
Boh., in the Sommer collection, which he recently presented 
to the Oxford Museum. 
From the description, it seems fairly certain that Stropho- 
somus verrucicollis, Fst.(Ann. Soc. Ent. Belg. 1899, p. 390), 
from the Congo, also belongs to this genus. 
The angulate elytra and tuberculate thorax would at onee 
distinguish these insects from the other African “ Stropho- 
somus,” and they have more the appearance of very small 
Blosyrus, which may however be distinguished by the very 
different structure of the epistome and lower surface of the 
rostrum, the more prominent eyes, and the straight hind 
margin of the first ventral segment.

with an indefinite pale stripe ; the apical area with irregular 
dark brown and paler patches ; these markings may become 
more or less obsolete.
