nesting habits of the species and his experience of the difficulties of 

 obtaining records of them with the camera. (See page 17.) 



Mr. F. W. Frohawk exhibited a selection of a series of Anosia 

 ple.rippus bred by him from ova in this country. This was the 

 first recorded breeding of the species in Europe. He received a 

 living female on August 8th, 1911, from Mr. Gerould, of Hanover, 

 N.A., and eggs were laid on that day. In about 90 hours they 

 commenced to hatch. The larval stage lasted 16 days, and the 

 pupal stage 15 days. Thus the total time taken from ovum to 

 imago was between 34 and 35 days. One male bred was very large, 

 measuring 4fin. = 115mm. Mr. Frohawk recounted the instances 

 of this species being captured in this country, some 24 in number, 

 from the year 1876. 



Mr. Hugh Main exhibited larvae of a species of Trmgrcorn (Cole- 

 optera), yacerdes iiielaniira (CEdemeridfB), obtained from logs of 

 timber lying on or in the ground. He also showed a very fine 

 gynandromorphic example of Erini/aster lanestris, bred by Mr. E. 

 P. Sharp, of Eastbourne. The left wings and antenna were male, 

 and the right wings and antenna female. The abdomen was like 

 that of a female, but the genitalia had not yet been examined. 



Mr. Edwards exhibited a fossil shark's tooth, Carcharodon 

 megalnda, from Mexico, and contributed the following note : — 



"The interesting genus Carcharodon has one extinct species in 

 the Cretaceous, and several others distributed in Tertiary formations 

 in nearly every part of the world. The teeth of some of the 

 Tertiary species measure five inches along the margin and four 

 inches across the base, and it is evident that they belonged to 

 sharks so gigantic as completely to dwarf the existing species. 

 That these giant Lamnida; have only recently become extinct, is 

 proved by the fact that similar teeth have been dredged from the 

 bottom of the Pacific. Carcharodon rondeletii, found from the 

 Mediterranean to Australia and New Zealand, is said to grow to 

 a length of 40 feet." 



Mr. W. J. Kaye exhibited two plants of the beautiful South 

 American orchid, Sophronitis grandiflora, and called attention to 

 the intense coloration of the flowers on one of the plants. He 

 also showed specimens of the syntomid, Diptilon hallerate from 

 South America, in which the secondaries were so shaped and rolled 

 towards the abdomen as to give the moth the appearance of a 

 dipteron.
