ABSTRACT OF PROCEEDINGS, 



JANUARY 9th, 1890. 

 T. R. BiLLUPS, Esq., F.E.S., President, in the Chair. 



Messrs. T, Grover, F, H. Atkinson, and C. F. Johnson 

 were elected members. 



Mr. Billups exhibited Andrena nigro-cBua,, Kirb. and its 

 internal parasite Sty lops, taken at Dulwich, June, 1889; and 

 a living series oi Andrena clarkella, Kirb. and its rare parasite 

 Nomada borealis, Zett., dug from its nidus on the 6th inst. in 

 the neighbourhood of Hastings, by Mr. Bennett, one of the 

 Society's country members. 



Mr. Jenner Weir exhibited specimens of Hesperia lineola, 

 Ochs. (the new British butterfly discovered by Mr. Havves), 

 which he had obtained many years ago, but was not certain 

 whether in Kent or Sussex ; and a Sussex specimen of Hesperia 

 thaumas, Hufn., which bore a very close resemblance to H. 

 lineola, and could only be distinguished from that species by 

 the light brown tips to the antennae, which in the latter were 

 black. For comparison he showed undoubted H. thaumas, 

 British, and H. lineola, from Chamouin. 



Mr. Hawes, who was the first to notice this butterfly in 

 Britain, also exhibited the specimens taken by himself, and 

 remarked that it was quite by accident that he met with the 

 species, which was undoubtedly distinct from H. thaumas. 

 Being in want of a series of the latter for his collection, in 

 July, 1888, he caught a good number, and on reaching home 

 he noticed that three of those taken were different to the 

 others; and on reference to the European collection at the 

 British Museum, it was ascertained that they were H. lineola — 

 a species not hitherto recorded as occurring in Britain. Ow- 

 ing to its close resemblance to H. thaumas, there was little 

 doubt that it had been overlooked in this country. The 

 chief point of distinction was found in the coloration on the 

 under side of the antennae. In H. thaumas this was of a faint 

 buff, while in H. lineola it was a decided black. 



Mr. Carrington remarked that he thought all would con- 

 gratulate Mr. Hawes in adding a butterfly to the British list — 

 it was a privilege that fell to the lot of very few. When Mr,
