A lecture was delivered by Mr. F. N. Pierce on " The Androconial Scales of 

 Butterflies." He explained that these scales were oidy found upon the males of 

 the various species, and were even in that sex uncertain. The lecturer instanced 

 the entire absence of this kind of scale in the case of the large group of the 

 Lycasnidse, in such species as had brown males. Mr. Pierce described a hitherto 

 unobserved scale, which he had discovered when examining the male of Lycxna 

 agestls, which appeared to be not only confined to the " blues," but to a very small 

 area consisting of a few of these new scales, on the under-side of the fore-wings, at 

 the extreme base of the inner margin. He also enumerated some of the theories 

 put forward from time to time as to the utility of these androconials. The lecture 

 was fully illustrated with micro-photos of the actual scales, shown through the 

 lantern. A discussion followed, in which most of the Members present took part. 



Mr. F.N. Pierce exhibited specimens of the British Lycxnidx in illustration 

 of his paper. Mr. Wm. Mansbridge, a short series of Pygsera curtula from Ireland, 

 one specimen showing failure of the brown scales at the tips of the fore-wings.

 papilionaria and Ellopia prosapiarhi, the latter showing the dusky-greyish suffu- 

 sion characteristic of the locality. Dr. J. Cotton, a lantern slide of several British

 Sweeting and Wm. Mansbridge, lion. Sees.
