Mr. R. C. Bradley showed Ephenella marginata from Bournemouth. Mr. E. 

 C. Tye read a paper (written conjointly with Mr. Gr. W. Wynn) on the Lepuloptera 

 of Marston Green ; it was written with the purpose of showing what might be done 

 in that district rather than what had been done ; and to recommend members to 

 work it, as it lies very near to Birmingham, and is easily got at. The paper de- 

 scribed the ground, which includes Packington Park and many fine woods and lanes, 

 and also gave a list of species already taken there. 



March 2nd, 1891.— Mr. R. C. Bradley in the Chair. 



Mr. J. J. Quirke, Jun., Haudswortli, was elected a Member. 



Mr. R. C. Bradley showed Trypeta centaurere from Moseley. Mr. Q-. H. Ken- 

 rick showed a specimen of TriphcBna pronuba, bred this January from eggs found on 

 a withered lime leaf early last September. Mr. Kenrick read a paper on " Tempera- 

 ture : its effects on some insects not found in this district." He pointed out the 

 great importance of temperature in affecting the distribution of insects ; he said 

 that most insects were very susceptible to heat or cold during some period of their 

 existence, which period varies in different species ; and that a difference of a few 

 degrees would kill them off or prevent their development. He quoted a number of 

 species in illustration, showing how their distribution was affected by various 

 temperatures. He believed that this extreme susceptibility often assisted evolution 

 very materially by isolating species. The paper was illustrated by some admirable 

 maps and specimens of the species treated of. — Colbean J. Wainwkight, Hon.

 different ; the paper was illustrated by the author's preparations, thrown on a screen
