was not Ochromyia jejuna, as stated in the publications re- 
ferred to above, but O. obscurepennis, Bigot. The following 
note by Col. Yerbury accompanied the series of this species in 
the British Museum :—* Very common in shady places. I 
have more than once seen this fly trying to take her burden 
from a large ant (Lobopelta sp.)—regular ‘ pulley-hauley ’ 
game.’ Col. Yerbury believed that the hold of the fly’s 
tongue was given by suction and not by piercing—a conclusion 
probably supported by Mr. Lamborn’s observation that the 
fly could drop the pupae at any time. It was clear, however, 
that the tongue was used asa piercing organ when the fly 
was feeding on the Termites and ant-pupae. The following 
note by Col. F. W. Thomson, I.M.S. (Dehra Dun, U.P., India, 
Nov. 1907), was borne by a specimen of the Indian species 
Ochromyia jejuna in the British Museum :— 
‘T always noticed specimens of this species on the ground, 
or on a stone or leaf near an ant’s nest. On watching, I saw 
them swoop down on any ant carrying an ‘egg’ or larva, 
take it from the ant, carry it away a short distance, and proceed 
to suck it.” 
Col. Thomson’s record pointed to habits similar to those 
here described by Mr. W. A. Lamborn. It was to be noted 
also that the Ponerine ant Lobopelta, robbed by Ochromyia, 
was allied to the Driver ants and itself hunted in companies 
somewhat after the manner of a driver. 
Mr. E. E. Green observed that Dorylus orientalis was a 
garden pest, eating potatoes, dahlia roots, etc. Unlike the 
African forms it was largely or wholly a vegetable feeder. 
Col. YeRBuRY said that in Ceylon Ochromyia was predaceous, 
and took sugar and other things away from Camponotus ants. 
Mr. KE. E. Green also remarked on the structure and habits 
of Ochromyia. 
South American Papiiios.—Dr. K. Jorpan exhibited 
a series of species of the two groups of Papilios called by 
Haase Cosmodesmus and Pharmacophagus respectively, and 
said :—The American mimetic forms of Cosmodesmus, which 
contrast so strongly with their more normally coloured 
relatives, are undoubtedly modifications derived from a more 
generalised type, such as is represented by Papilio asius.
