Obs.—There is a genus indicated in Dejean’s catalogue, between 
Hybosorus and Ochodeus, under the name of Acallus, (Atimus, De}. 
Cat. 3rd edit.,) composed of three species ; emarginatus, Wiedemann 
[ Wiedemann has described no species under such name], from 
Java, affinis, Dej., and ciliatus, Dej., both from Senegal. This 
genus is evidently identical with Pheochrus of Laporte, (Hist. 
Nat. Ins. Col. vol. ii. p. 108,) placed between Geobius and Acan- 
thocerus, and composed of two species, P. Senegallensis and P. emar- 
ginatus (from Java). From the very short and slovenly description 
given of this genus, it is impossible to say whether it be identical 
with Sz/phodes or not.
