Ixvu 
were submitted to Dr. Warren of the Natal Museum, Maritz- 
burg, and they were sent on by him to Dr. L. Péringuey, 
the well-known Coleopterist of Cape Town. All the informa- 
tion that these gentlemen could impart was that the insects 
appeared to be a species of an ordinary dung-beetle (Aphodius 
marginicollis).’ 
“There is much more on the subject contained in the 
article, which, if you can get hold of it, might interest you. 
I am sending you all this to show you how gullible some 
white men are, when confronted with the trickeries of some of 
these wily native medicine-men. If you read the rest of what 
Mr. Bryant says on the subject you will notice that these 
doctors must use a considerable amount of dexterity in the 
‘way they immediately transfer their live stock to the passed 
excreta to keep up the deception.” 
In view of the facts brought forward by Mr. Barker, the 
statement made by R. A. Senior White, in “ The Indian 
Journal of Medical Research,” Calcutta, Vol. 7, No. 3, p. 568, 
required confirmation, and was, on the face of it, highly 
improbable. The “ disease,’’ as it is there stated to occur in 
Ceylon, was curiously similar to that described in Africa, 
and there was a vernacular name (“* Kurumini Mandima ” — 
“* Beetle-disease ’’) in the former as in the latter. Mr. G. J. 
Arrow had informed Prof. Poulton that the beetle, said to 
have been passed by a boy in Matale Hospital and figured on 
Plate LV, was certainly Onthophagus bifasciatus F. (probably 
a g and not, as represented, a 9), but that the other two figures 
supposed to be of the same species were different from it and 
from each other. 
Mr. DonistHoRPE exhibited a specimen of Argynnis ewphro- 
syne taken -in cop. at Darenth Wood on May 10, 1921, 
pointing out that it still retained part of the pupal sheath on the 
head, but was able to fly. Some discussion arose as to the 
effect of damage to the antenne on the flight of butterflies. 
EVERSIBLE GLANDS IN CHRYSOMELID LARVAE.—Dr. C. J. 
GAHAN exhibited larvae of the Chrysomelid beetle, Phytodecta 
viminalis L., and said his object in doing so was to call attention 
to the existence in these larvae of a glandular structure, which 
under certain conditions was everted between the 7th and
