136 THE ENTOMOLOGIST'S RECORD. 



year : — Mr. G. T. Bethune-Baker, Mr. J. Hartley Durrant, and 

 Commander J. J. Walker, R.N. He also announced that three 

 Committees, Finance, Publications, and Library, had been formed in 

 place of the Business Committee, and the names of the Fellows 

 appointed to serve thereon respectively. 



Breeding of C. hirundinis. — Mr. A. Bacot exhibited living 

 specimens of Gimex hirundinis, and gave an account of his breeding 

 experiments therewith. 



Stridulation in Saturniids. — Dr. K. Jordan exhibited samples of 

 the Saturnian genera Holocerq, LinJia, and Ortjiogonioptilntn, and 

 demonstrated the presence of a kind of stridulating organ, absent in 

 the male; also two species of Graphipterns, Gr., G. rotundatns, Klug, and 

 G. pelletieri, Castln., from Algeria, both provided with stridulating 

 organs. He said that the latter was found in association with 

 Cicindela touquii, Guer., and that although the difference was apparent 

 in the cabinet, in nature they were practically indistinguishable. Dr. 

 C. J. Gahan remarked on the great interest in the discovery of these 

 organs in the female Henucha ; the only other instance known to him 

 being that of Phonaphale, a genus of beetles of the family Boxtvichidqe. 



A rare Locust. — Mr. 0. E. Janson exhibited a fine specimen of 

 Markia hyatrix, Westw., a rare and remarkable locust from Costa Rica. 



Migration in a Mimetic Association. — Professor E. B. Poulton, 

 F.R.S., a case of butterflies and mimetic moths which had been 

 observed migrating together from one valley to another in Selangor, 

 F.M.S., and read a letter from Mr. A. R. Anderson, the observer and 

 captor, as to the conditions under which the exhibited specimens were 

 taken. 



Hibernating Diptera. — The Professor also exhibited examples of 

 Musca autumn alis, De G., found hibernating, as in previous years at 

 St. Helens, I.W. The numbers appeared to be greater than in any 

 winter except that of 1914-15 (cp. Prac. Ent. Sue, 1915, p. 21). 



Habits of Ants. — Mr. Donisthorpe brought for exhibition a number 

 of workers of Acanthomyops (Dendrolasiiis) futiginosus, all of which had 

 workers of A. umbratiis fastened by their mandibles on to their legs, 

 etc., taken at Woking in August, 1915, when a fierce battle was in 

 progress between the two species. It served a good opportunity to 

 establish how soon the Myrmecophils entered the new nest, and those 

 observed in the five ensuing years were also exhibited. 



Bkekding of C. dispar race rutilus. — Mr. Lachlan Gibb showed 

 several forms of the female of Chrysophanu s dispar race rutilus, bred 

 by Capt. Bagwell Purefoy. After eight years experimental breeding 

 in this country, it was found that the blue sheen on the undersides of 

 the species approximated more generally to that of tbe extinct form, 

 but the broad orange band on the underside showed a tendency 

 to diminish. 



Papehs. — Tbe following papers were read: "Notes on the 

 Orthoptera in the British Museum. The group of Etqirepocnemini," 

 by Dr. B. P. Uvarov. " Notes on Synonymy and on some types of 

 oriental Carabidae in various foreign Collections," by Mr. Andrewes. 



March 2nd. — This being the first meeting held at the Society's 

 new premises, 41, Queen's Gate, South Kensington, S.W., the Presi- 

 dent, the Rt. IrJon. Lord Rothschild. F.R.S., delivered an address of 

 welcome to the large number of Fellows and visitors present.
