tearing open the egg-cocoon of a spider. These insects were 
determined by Mr. B. P. Uvarov as Mantispa annulicornis 
Gerst. 
BUTTERFLIES FROM NEW GUINEA AND Peru.—Mr. G. 
TatBor exhibited on behalf of Mr. J. J. Jorcey :— 
(1) A red-banded Mimetic Combination consisting of 
Papilio euterpinus G. & 8., 3, Papilio cacicus inca R. & J., 2, 
Pereute cheops Stgr., 2, and Adelpha lara Hew. 
The red-banded 2 form of inca is different to the similarly 
coloured 2 f. zaddachi Dew., and is strikingly like ewterpinus. 
This combination exists in Peru, Colombia, Venezuela, and 
Kceuador. 
(2) A new Papilio from Ecuador, allied to cutorina Ster. 
(3) Troides lydius Feld. A male with a remarkable colora- 
tion, of deep copper or morocco red. This specimen was 
given to Mr. C. Pratt in Amboina, and was stated to have 
come from the island of Morotai, north of Halmaheira. 
(4) Troides from the Wangaar District, south of Geelvink 
Bay.—T. paradisea Stgr., 2, which may not be different from 
the typical form, 7’. meridionalis Roths., 9, known previously 
only from British New Guinea, and 7. tithonus misresiana 
J. & N., 2, apparently quite the same as the Arfak specimens. 
A RARE British ApHip.—Mr. DonistHorPE exhibited a 
specimen of the rare Aphid, Stomaphis quercus L., several 
specimens of which he had taken on the trunk of an oak tree 
attended by ants, Acanthomyops (Dendrolasius) fuliginosus 
Latr., at Woking on September 22 and October 7, 1921. 
This Aphid appears to be very scarce in Britain, the only 
other published record being from Dulwich, where it was 
taken by Walker many years ago. 
Mr. A. T. J. Janse concluded his account of methods of 
collecting while travelling in South Africa, illustrated with 
lantern slides.
