antenne, the right side of the abdomen, and the left side of 
the genitalia were obviously 9 ; and its other sexual characters 
(as far as they could be recognized) seemed to be distinguished 
in much the same way—the ¢ and 2 elements being every- 
where separated by the longitudinal axis of the insect, but 
some of each lying to the right, and others to the left of 
that axis. 
Mr. Morice said that Mr, Harwood had kindly authorised 
him to present the specimen to the National Collection at 
South Kensington. 
A discussion followed on the occurrence and forms of 
gynandromorphism in the various orders of insects, in which 
Mr. Merririetp, Mr. A. J. Cuitry, Mr. Hues Main and 
other Fellows joined, Mr. H. St. J. DonistHorre mentioning 
that in his experience the phenomenon never appeared in 
Coleoptera, while the Presipent gave it as his opinion that 
the form assumed in the exhibit under notice was unique. 
Protection 1n TrnemD Pupa.—Colonel Cuarzes T. BrncHam 
exhibited the remarkable pupa of a Tineid, in appearance 
exactly like the head of a snake. This pupa and the moth 
shown with it, and figured in the Society’s Transactions for 
the current year, were procured at Maymyo in Upper Burma 
by Col. Waller-Barrow, R.A.M.C. 
ASSOCIATION OF BUTTERFLIES WITH APpHIDES.—Colonel 
Bryeuam also explained an exhibit made by him in illustra- 
tion of the curious habits of butterflies belonging to the 
genera Gerydus and Allotinus, Col. Waller-Barrow discovered 
that these butterflies join with ants in attending Aphidz for 
the sake of the sweet liquid exuded by the latter when touched 
gently. For this tapping the ants, as is well known, use their 
antenne, Gerydus,and Allotinus, it seems, use for the same 
purpose their abnormally long fore-legs. In the specimen of 
Gerydus boisduvalt, Moore, which was exhibited, it was to be 
noted that the tibie of the legs were flattened. Whether 
function in this case has modified form or not he could not 
presume to say: he only drew attention to the fact of the 
flattening. Col. Waller-Barrow had informed him that the 
butterflies hover over the aphides for a long time before set- 
tling, and that though numerous ants might be attending the
