Brenthis selene from La Granja and a pair of B. hecate from 
Hungary, showing the remarkable approximation of the two 
species in the markings of the under-side. 
Association of Ants. —Mr. H. St. J. Donisthorpe brought 
for exhibition a case containing a small nest of about 30-40 
living examples of Formica rujibarhis, vax.fusco-rujibarbis, from 
Whitsand Bay, August 1909, into which had been introduced 
a queen of Formica rufa from Nethy Bridge (May 1909). 
The queen had been accepted by the other ants in a few days. 
Male Beetle with Female Antennae. —Mr. C. 0. Water- 
house, on behalf of Mr. J. C. Moulton, of the Sarawak Museum, 
exhibited a Longicorn beetle of the genus Cliloridolxmn, in 
which the right antenna was much shorter than the left. 
The specimen appeared to be a male in every respect except 
in the length of the right antenna, the joints of which were 
a trifle shorter than those of a female. Mr. Moulton was 
inclined to think the specimen might be gynandromorphous. 
Mr. Waterhouse suggested that it might rather be regarded 
as a malformation, 
Teratological Example of a Beetle. —-Mr. W. E. Sharp 
exhibited an example of Calathus mollis, having the right 
anterior tibiae and tarsus in triplicate. He said that such 
reduplication was not uncommon, but that it was seldom so 
perfect in detail. The occurrence raised the whole question 
of the cause of the reduplication of such parts, whether it was 
due to hereditary defect, or to external stimulus exciting cell 
reduplication. A discussion folloAved in which Professor E. 
B. PouLTON, F.R.S., Dr. T. A. Chapman, Mr. J. W. Tutt, the 
Rev. F. D. Morice, and Professor Hudson-Beare and other 
Fellows participated. 
Zygaenid Forms. —Mr. L. W. Newman showed a case contain¬ 
ing the following forms of Zygaena liippocrepidis, all taken in 
June 1908 in one small field in the neighbourhood of Bristol, 
by Mr. H. J. Smallcombe: (a) analogous to A. fili'pendidae, 
var, chrysanthemi, {b and c) examples with the normal carmine 
coloration replaced by yellow, analogous to A. Jilipendulae, ab. 
jiava, Robson, and by pink; and {F) an example with yellowish 
spots, otherwise normal. Also a specimen of Z. lonicerae 
captured at the same place, with the markings broadly confluent.
