Mate Branps avracKep By Pexsts.—Professor KE. B. 
Poutton, F.R.S., exhibited male specimens of the Danaine 
butterflies Amauwris egialea, Cram., and Limnas chrysippus, 
L., collected at Ibadan, near Lagos (December 5-12, 1906), 
by Mr. H. 8. Gladstone. The interest of the specimens 
lay in the fact that the scent-producing patch near the anal 
angle of the hind-wing had been eaten out on both sides— 
very cleanly and neatly in the case of the Amauwris—although 
only a minute portion of any other part of the wing-surface 
had been attacked. The abdomen was almost entirely want- 
ing, but the basal portion which remained showed that it had 
been almost certainly devoured. The head and thorax also 
appeared to be quite empty. Professor Poulton stated that 
he had occasionally observed the evidence of such attacks upon 
the supposed scent-patches of Danainx, but he believed that 
the Amauris was the best and clearest case he had ever seen. 
This special attack upon Danaine scent-patches becomes of 
even greater interest and significance when we remember that 
dead specimens of this and the allied sub-family, the /thomine, 
are less liable than other specimens to be injured by the pests 
which destroy insect collections.* On the other hand, the fact 
that the whole interior of the body was devoured appears to 
indicate indifference on the part of this particular pest to any 
specially protective substances existing in a desiccated state ;
