widespread grasshopper in Europe. Two 9 9 of a species 

 peculiar to the mountain, St. cazurroi, were also shown, one 

 torn, one not torn. But of the common St. viridulus almost 

 every specimen was mutilated. 



Mr. F. W. Pierce exhibited drawings of the genitalia of 

 Noctuid moths, and also with tho lantern a number of slides 

 showing the respective peculiarities of many members of the 

 Genus. Among other things he drew attention to the fact 

 that in the case of the Txhiocampidx the genitalia were 

 widely dissimilar, while his investigations had led him to 

 conclude that ashworthii, at present ranked as an Agrolis, 

 should more properly be included in the Noctua group. 



Mr. L. B. Prout suggested that the arrangement was a 

 physiological necessity for the separate existence of the various 

 species of Tamiocampa, as they all observed practically the 

 same habits and emerged simultaneously. 



A discussion followed upon the value of the genitalia for 

 the purpose of distinguishing species, in which Mr. O. C. 

 Champion, Mr. A. W. Bacot, and other Fellows joined.

Exhibits. 



Mr. H. St. J. Donisthorpe exhibited a melanic specimen 

 of a Grammoptera, discovered by Mr. C. J. C. Pool at Enfield, 

 which appeared to be quite distinct from any member of the 

 genus recorded in Britain, though Mr. E. A. Waterhouse had 

 taken a similar example thirty years ago in Yorkshire. Mr. 

 C. J. Gahan, to whom the specimens had been referred, 

 considered them to be a form of G. ruficomis, F.
