MEETINGS. 173 



taries, and all the interesting finds duly noted. The gist of 

 these and similar monthly records will be embodied in the 

 annual sectional reports. 



A promised paper not having arrived, Mr. E. D. 

 Marquand filled up the evening with some extempore re- 

 marks (illustrated by black-board sketches) on the " Sexual 

 Scales of Butterflies." These peculiar scales, he said, were 

 to be found only on the male insects, and it was very curious 

 that they occurred only in certain families of Butterflies, such 

 as those containing the Garden White, the Meadow Brown, 

 the Blues, and a few others ; in other families nothing of the 

 kind was found. The scales assumed various shapes in 

 different species, being often tufted or plumose, or in the case 

 of the Blue Butterflies, shaped like a battledore; but in all 

 cases they were very unlike the common scales with which 

 they seem to be promiscuously mixed without pattern or 

 symmetrical order. There is every reason to believe that 

 they merely serve the purpose of ornament. 



Monthly Meeting held on July 13th, 1892, Mr. J. Whitehead, 

 President, in the chair. 



The minutes of the last meeting having been read and 

 confirmed, Mr. T. W. Palmer was unanimously elected a 

 member. 



Since the last meeting five weekly excursions of the 

 Society had taken place in accordance with the programme, 

 and interesting accounts of the various finds and objects of 

 interest were given by the sectional Secretaries ; this, with the 

 discussion which followed at various points, pleasantly occu- 

 pied the whole evening.
