NOTES ON THE GENUS LYC.ENA. 



By Richard South, F.E.S. 



(Continued from p. 52.) 



First, a word concerning Lyccena corydon. Prof. Blachier, of 

 Geneva, has most kindly informed me that the variety, PL I., fig. 1, 

 has been named lucretia by M. Garchet (' Annales de la Societe 

 entomologique de France, 1877,' bulletin, p. 79). Such a remark- 

 able form is certainly worthy of a distinguishing appellative. 

 Prof. Blachier also mentions a small grizzled (grisatre) example 

 of corydon, which was taken in the Valais, and expands only 

 27 mm. Mr. C. A. Briggs has British specimens even smaller 

 than this; two (male and female), which he has most courteously 

 shown to me, measure respectively 25 mm. and 22 mm.

Male. — Blue, with either a tinge of violet or mauve, more 

 frequently the latter. The specimens figured, Pl.II., figs. 1, 2, 3, 

 have each a distinct shade of blue : that represented by fig. 1 is 

 from Aberdeenshire, and is blue shot with mauve, while fig. 2 

 shows a male icarus, closely approaching male bellargiis in 

 colour; and fig. 3 is a decidedly violet specimen. These two 

 last are from Ireland, and were kindly sent me, together with 

 others (to which more particular reference will presently be made), 

 by Mr. Percy Russ, of Culleenamore, Sligo. Several of the males
