104 THE ENTOMOLOGIST. 



albinism, particularly round the outer margin of the hind wings. 

 In conjunction with this there was a great deal of distortion, the 

 affected wings often being shortened or crumpled, and one which 

 I noticed to be flying awkwardly was found to be entirely desti- 

 tute of the left hind wing. 



Melanargia larissa was the only species of this genus that I 

 secured, although I occasionally saw Marbled Whites in the 

 neighbourhood of the Spanc Kiver near Kurkut at the end of 

 May. Probably they were all of this species, for their flight was 

 considerably stronger than that of the British galatea. This 

 specimen is larger than mentioned by Kirby, measuring 63 mm., 

 and it is darker, having a broad, almost unbroken submarginal 

 black band. 



Thecla acacice. — The Hair-streaks are very local, and one 

 might live in a locality for years and never find a species, which 

 might nevertheless occur regularly and freely in one restricted 

 spot. So it is not surprising that I only encountered two species. 



Acacice I found in fresh condition flying round large clumps 

 of a fine species of vetch under a rough hedge near Kukus in the 

 last week in May. 



Callophrya ruhi. — I found one specimen in a ravine near 

 Irikli in April. 



Chrysophanus thersamon. — This very handsome little butterfly 

 was exceedingly abundant on Janes plain, but elsewhere I only 

 met two isolated specimens, one near Kasimli in July and the 

 other at Yenikeuy on the Ardjan river in August. At Janes it 

 was abundant from the end of August throughout September, 

 1917. In 1918 the first brood appeared the first week in May 

 and continued throughout June, after which only a few isolated 

 specimens were met with until the end of August, when it again 

 appeared abundantly. Its flight is somewhat difierent to phlaas, 

 being shorter and rather more rapid. It was addicted to the 

 blossoms of Poli/gonum rumicis and heliotrope — the latter a plant 

 which is abundant in the district on newly-turned land and is 

 very attractive to numerous small species of Lepidoptera. It was 

 charming to see several pairs of thersamon flying round and 

 settling upon this plant, the intense colour of their wings forming 

 a striking contrast to the white of the flowers. I took several 

 specimens of the var. omphale, which are distinctly smaller, 

 expanding only 27-30 mm. The ground-colour is rather more 

 yellowish than in the type, and the spots above are larger while 

 beneath they are distinctly smaller. The tails are longer and 

 more slender. 



C. phlceas. — Proved very interesting in some respects, the 

 specimens I obtained being strikingly different to British forms. 

 One solitary specimen approaches the British type, but in this 

 the spots on the fore wings are larger. The vast majority of 

 specimens were darker than the darkest British forms I have
