24 ? of M. autuitiiialis. Spider's web was far more evident 

 than in previous years and perhaps pointed to the reason for 

 the lessened number of the flies. The position of the groups 

 was as described in Proc. Ent. Soc, 1915, p. xxi, and 1918, 

 p. xxii, where it was also recorded that the females were far 

 more numerous than the males, 



Ophion undulatus, Gray., bred from Bombyx quercus, 

 l., cocoons, from n. staffordshire. — prof. poulton 

 exhibited six examples of this fine Ichneumonid, said by Mr. 

 Claude Morley to be common neither here nor on the continent 

 (■' Brit. Ichneumons," vol. v, Ophionmae, p. 279). The 

 specimens were bred by Mr. F. C. Woodforde and appeared in 

 following order:— 1918, June 11—1 c?, June 21—3 ?; 1919, 

 June 12 — 1 o, 1$. The first was from B. quercus, the others 

 from the var. callunae, Palmer. The cocoons were from wild 

 larvae, those of the first four from the Burnt Woods, Market 

 Drayton, of the last two from Ashley Heath in the same 

 district. 



ObSERVAIIONS ON THE RED (GREGORYI, DiST.) AND GREEN 



(sPECiosA, Melich.) forms of the Homopteron Ityraea 

 nigrocincta, Walk., at Kibwezi, B.E. Africa. — Prof. 

 PouLTON said that, after receiving the specimens exhibited 

 at a previous meeting (Proc. Ent. Soc, 1918, p. Ixxviii), 

 he had written to Mr. W. Feather at Kibwezi, suggesting that 

 it would be interesting to watch a particular set of nymphs, 

 so as to determine whether the imagines emerged in batches 

 of each colour. Although this point was not definitely settled, 

 the following observations recorded by Mr. Feather, who had 

 recently returned to this country, were of much interest. 

 In bringing them forward a fine series of specimens collected 

 Dec. l-ll, 1918, by the same naturalist, was also exhibited 

 to the meeting : —
