insects impaled by shrikes. Dr. Sharp, Mr. K. Trimen, and 

 Mr. McLachlan made some remarks on the subject of the 

 impalement of insects by birds. 



Mr. Goss exhibited, for Mr. Cameron, an apterous male of 

 MiitUla contraeta taken by Mr. Rothney in Barrackpore, 

 India. The specimen was stated to be the first recorded 

 instance in this species of a wingless male, and was also 

 abnormal in having the thorax incised laterally. 



Dr. Sharp called attention to the fact that at a recent 

 meeting of the Society (March 20th, 1895, see Proc, 1895, 

 p. X.) a specimen of a supposed dimorphic form of one of the 

 species of Dytiscm was examined, and Prof. Stewart enquired 

 whether any anatomical examination had been made of the 

 sexual organs. Dr. Sharp said that in the Comptes Rendus 

 Soc. Bordeaux, 1894, there was an account of the examination 

 of the sexual organs of the supposed second form of D. mar- 

 lliu'ilis by Mons. Peytoureau, who came to the conclusion 

 that it was really a distinct species, which he called D. herheti. 

 Dr. Sharp suggested that there must be some doubt as to 

 M. Peytoureau's conclusion as there was a series of these 

 double forms in connection with this genus, and it would be 

 a very extraordinary fact if in one case the second form 

 should be a distinct species, while in other species of the 

 same genus the form corresponding to it should be only a 

 variety. Mr. Champion and Mr. Tutt made some remarks 

 on the subject. 



Prof. Poulton exhibited examples of the type labels now in 

 use in the Hope Collection at Oxford, and illustrated their 

 employment by projecting on the screen, by the lantern, a 

 photograph of the Westwood types of African Eusemm 

 described in F. Gates' " Matabele Land " (Lond., 1881). He 

 said that such labels, having been once set up in type, could 

 be reproduced in electrotype very cheaply and efficiently. 

 Black ink was considered better than red on account of its 

 greater permanence. Mr. Verrall said he was of opinion that 

 no species should be described from a single type, but from 

 many specimens, and he wished every so-called " type " could 

 be destroyed as soon as a species had been described from 

 ■it. He knew of cases in which a "species" had been
