approximation of the two species in the markings of the under-side. Mr. H. 

 St. John Donisthorpe broug-ht for exhibition a case containino- a small nest of 

 about 30-4.0 § ^ living examples of Formica rufibarbis, var. fuscoruilharUs, 

 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 otlier ants in a few days. Mr. C. O. Waterhouse, on behalf of Mr. J. C. 

 Moulton, of the Sarawak Museum, exhibited a Longicorn beetle of the genus 

 Chloridolum, in which tlie right antenna was much shorter than the lef t ; the 

 specimen appeared to be a male in every respect except in the length of the 

 riglit antenna, the joints of which were a trifle shorter than those of a female. 

 Mr. Moulton was inclined to tliink the specimen might be gynandromorphous. 

 Mr. Waterhouse suggested that it might rather be regarded as a malfonnation. 

 Mr. W. E. Sliarp exhibited an example of Calathus mollis, having tlie right 

 anterior tibia and tarsus in triplicate ; he said that such redixplication was not 

 uncommon, but that it was seldom so perfect in detail. Mr. L. W. Newman, a 

 case containing tlie following forms of Zyg^na hippocrepidis, all taken in June. 

 1908, in one small iield in the neighbourhood of Bristol .- (a) analogous to A 

 fiUpend^da^, var. chrysanthemi, (h and c) examples with the normal carmine 

 coloration replaced by yellow, analogous to A. fiUpendul^, ab. /am, Eobson, and 

 with pink, and (d) an example with yellowish spots, otherwise normal ; also a 

 specimen of Z. lonicerm captured at tlie same place, witli tlie markino-s broadly 

 confluent. Mr. G. Bethime-Baker, three nests of a species of Lasiocampid from 

 Mount Elgon, Albert Nyanza, belonging to the same group as TAatmaiopca 

 VTocessxonea ; he had been consulted relative to the possibilities of using the 

 silk of which the long pouch-like "nests" were constructed. Mr. G. A. K 

 Marshall said that they belonged to a species of Anaphe. Professor E B 

 Poulton, F.R.S., read a "Preliminary Note on Mr. A. D. Millar's experimental 

 breeding of forms of the Nymplialine genus Euralia in Natal," by Mr Eoland 

 Trimen, M.A., F.E.S., and exhibited examples of the species and forms referred 

 to; he said that Mr. Millar was greatly to be congratulated on his success in 

 obtaining the long-wished-for proof that Euralia wahlbergi and E. mima were 

 foiins of the same species. Prof. Poulton also exhibited a set of six Euralia 

 anthedon, Doubl., and four E. duUa from Lagos, tlie western representatives of 

 E. xmMhergi and E. mima respectively, giving it as his opinion that after the 

 proof obtained by Mr. MiUar, the western butterflies were also tlie diinorpliic 

 forms of a single species. 



The following papers were read :-" Tliird Paper on the TetrigimB (Ortho- 

 ptera) m the Oxford University Museum," by J. L. Hancock, M.D. " Descrip-
