the gap between this and Stephanodes, for example, which is 
very great, is partially bridged by Mr. Enock’s discovery, and 
possibly other links may be found in the future. 
ArricAN CuHaraxes.—Mr. H. Rownann-Brown exhibited 
some drawers of Miss Founrainn’s bred series of African 
Charaxes. PRoressor PouLTon commented on these, regretting 
that the parent had not been preserved with the corresponding 
offspring in each case. 
A Pompitip Mimickep sy A Repuviip Bue.—Dr. CHArpMan 
exhibited a box of. insects to illustrate a case of mimicry, on 
which he read the following note :— 
“In March and April, both at Hyéres and at Amélie-les- 
Bains, my attention was attracted to a Reduviid bug, P2rates 
hybridus, Scop. I followed up one or two on the wing, 
taking them for Pompilid Hymenoptera, and when they settled 
on the ground their movements were precisely those of 
Pompilus when hunting on the ground—sharp, active, jerky, 
and taking wing at once if alarmed. The red colouring on 
the elytra was, when running, much like the red of a Pompilid 
body between or under the wings. After the first one or two 
specimens one of course easily distinguished the bug for what 
it was. 
“One would, at first, take this for a case of Batesian 
mimicry, but on picking up the bug, it often occurred that 
one was stung, about as sharply as many Pompilids do, and 
some are fairly proficient therein. The sting was of course 
the thrust of the beak or proboscis, of which not a few Reduviid 
bugs can make effective weapons of defence. The sting not 
only enhances the resemblance to an Aculeate, but gives a 
thoroughly Miillerian aspect to the association. 
‘There are very many bugs of similar form and brilliant 
coloration, Pyrrhocoris, etc. These are mostly slow-moving 
and harmless, and have, I imagine, no connection with the 
species under notice, but are probably cases of warning 
coloration of distasteful morsels. 
“In the Cambridge Nat. History, Dr. Sharp quotes Seitz as 
recording a Reduviid at Corcovado in Brazil that exactly re- 
sembles a wasp of the genus Pepsis, and moves in the same 
wasp-like manner, and Prof. Poulton tells me of a British
