116 POLYOMMATUS (LYCjENA) MGOTX. 



greenish-yellow line running between two green ones 

 darker than the ground colour. 



At the bottom of the sides along the lateral ridge is 

 a whitish line commencing on the third segment and 

 continued round the anal extremity. Between the 

 dorsal and subdorsal lines on segments three to ten 

 are faintly paler oblique lines of yellow-green, viz. one 

 on each segment sloping downwards and backwards ; 

 the warts on the twelfth segment are very often sud- 

 denly projected considerably, and then a circle of fine 

 short hairs is visible on their extremities. The surface 

 of the body is also clothed with similar hairs. The 

 head is black, having the base of the papillae and a 

 streak across above the mouth of buff colour. 



They had all turned to pupae by the 24th of June, 

 one of them being slightly attached to a stem of the 

 plant by the anal extremity, and lying, like the others, 

 amongst a few loose threads at the very bottom of the 

 stems and partly in the earth. 



The pupa is about five lines long, smooth, but with- 

 out polish, the top of the head slightly projecting, the 

 thorax rounded, the abdomen plump, curving on the 

 back outwards and backwards towards the tip, which 

 is hidden in the larva skin, the wing-cases prominent 

 and long in proportion. It is of a dull green tint, 

 with a dark brown dorsal line of arrow-head marks. 



The butterflies appeared July 5th to 17th. (W. B., 

 2, 69 ; E.M.M. V, 241.)

"When Professor Zeller in 1867 published his most 

 interesting history of this species in the 'Entomo- 

 logist's Monthly Magazine' (vol. iv, pp. 73-77), he 

 stated it to be generally accepted that Lyccena Arta- 

 xerxes is only a variety of Medon, Hufnagel (Agestis, 

 Ochs.) ; and yet it appeared to him extremely impro-
