Somerset, and in it found two males of this species. Tiie 

 captor remembered taking the specimens, in 1874, close to a 

 small quarry iu the ueighbourhood of Frome. These speci- 

 mens were exhibited by Mr. St. John at a recent meeting of 

 the Entomological Society of London. By the kindness of 

 Mr. Cambridge I have been enabled to examine the two 

 Bloxworth specimens also, and can readily understand how 

 easily the species may be overlooked. The capture of an- 

 other example at Bournemouth, by Mr. P. Tudor, is recorded 

 by Mr. Cambridge in Tlic Entomologist, 1885. In the Young 

 Naturalist for 1889, Mr. J. Chappell, of Manchester, states 

 that about twenty-iive years earlier, Mr J. Clegg, of Oldham., 

 whilst collecting F. Alexis at Blackpool, caught a specimen 

 with tails. This passed into Mr. Chappell's possession, but 

 was regarded as L. Batica, and has only recently been recog- 

 nised. If no accidental misplacement of specimens occurred, 

 this capture is very remarkable indeed, and difficult to 

 explain. 



The foregoing are our only records of this species. The 

 localities in which taken seem to preclude the idea of 

 accidental introduction among plants, and it is possible that 

 in the wide extent of heaths ranging from Surrey through 

 Hants and Dorset a permanent locality for this species may 

 yet be discovered. 



Genus 1. POLYOMMATUS. 



Antennae slender, with a narrow club. Wings rounded, 

 the hinder without a tail. Upper surface in the male usually 

 blue, rarely brown ; in the female generally brown. Under 

 sides with numerous black spots, usually in white rings. 



Larv.e onisciform, feeding principally on papilionaceous 

 plants. 



PuP.iE blunt and rounded.
