 R. Adkin, Esq., F.E.S., President, in the Chair. 



Messrs. W. White, F.E.S., A. J. Hodges, T. H. Leech, 

 F.L.S., F.Z.S., etc., G. H. Verral, F.E.S., F. Grut, F.L.S., 

 F.E.S, F. J. Winkley, E. A. Waterhouse, H. A. Yardley, and 

 G. B. Routledge, were elected members. 



Mr. Sheldon exhibited examples of the spring and 

 summer broods of Scoparia angiistea, St., and stated that 

 he found the larvae of this species in the neighbourhood of 

 Croydon early in February last, the imagines from which 

 emerged in the following March. About the middle of 

 August of the same year he again took the larvae and 

 pupae of this insect in the same locality, the imagines 

 emerging the same month. This was, therefore, conclusive 

 evidence that the species was certainly double brooded in the 

 Croydon district. The examples of the spring brood were 

 more sluggish, and also much smaller than those of the 

 summer brood. 



Mr. Ince exhibited a comparative series of Nepa cmerea, 

 L., and remarked on the variety in colour of the abdomen, 

 ranging from red in some specimens to black in others. 



The following note from Mr. T. D. A. Cockerell was 

 read by Mr. Fenn : — 



" From observations made during the last few months, it 

 would appear that cases of mimicry are unusually prevalent 

 in the Colorado Rocky Mountain Region, some of them 

 being very remarkable. Vanessa antiopa is one of the 

 commoner butterflies, but is nevertheless considerably ex- 

 ceeded in numbers by one of the Locnstidce, which it 

 closely resembles on the wing. This grasshopper is nearly 

 of the same size as the Vanessa, and has its lower wings 

 of a black colour, with a broad yellowish-white border, the 

 general effect of the coloration being similar to that of V. 

 antiopa. Its manner of flight is also somewhat similar. Of 

 course, on close examination the two insects appear totally 

 different, and to anyone who has seen them in a cabinet only 

 it may appear incredible that one could be mistaken for the
