with observations on the name Dorydium. A13 
Perch., and percheroni, Guér.,* from South Africa, and 
C. marginatus and brunneus, G. R. Waterhouse, from 
Australia. I may say that the two latter are closely allied 
to, if not actually congeneric with, Dorydium (?) west- 
woodi, and do not belong to the South African genus 
Cephalelus. Next to Cephalelus, Signoret places the 
genus Dorydiwm, with the two species, D. lanceolatum 
and paradovum, Burm.; but for the latter he gives the 
locality Paris; and his insect is evidently paradowus, 
Herrich-Schiiffer ; Burmeister’s species being, as we have 
seen, Cephalelus infumatus, Perch., or a closely-allied 
species. 
It is clear that D. lanceolatum, Burm., must be 
regarded as the type of Dorydiwm, and that most of 
the species referred to Dorydiwm will have to be 
removed either to Cephalelus or new genera formed for 
them, if necessary. But this task I will leave to the next 
specialist who takes up the Jassidz.
