294 THE ENTOMOLOGIST. 



the end of May or in the beginning of June I could have netted 

 with ease a hundred specimens in a morning. It was most abundant 

 in the small woods in the valleys of the hills some miles on the road 

 to Tsaritsyn ; but it was also exceedingly common in the " Tschapurnik 

 Wald," and specimens were to be found in every small wood that we 

 worked. I took the first specimen on May 22nd. 



Polygonia c-albitm. — I only saw two examples of this species ; 

 these were taken on June 12th in a wooded valley opposite Sarepta; 

 they have very pale under sides and are extreme forms of 

 var. hutcliinsoni. 



Eugonia 2Jolychloros. — A single example was taken on June 20th, 

 sunning itself on a wooden barn. One or two hibernated specimens 

 were seen at lalta. 



Pyrameis cardui. —Common wherever we collected in Eussia, 

 and especially so at Sarepta ; a succession of emergences occurred 

 there during the whole period of our stay. 



P. atalanta. — A few at lalta. At Sarepta only seen in the 

 "Tschapurnik Wald," where there was an abundant growth of 

 nettle ; a plant usually rare in the district. 



Melitaea aurinia var. sareptana. — This handsome form of 

 M. aurinia was seen not uncommonly, when its localities were 

 discovered, but it was very local, haunting bushy slopes. It was 

 first seen on May 22nd, on which day all the specimens were worn ; 

 eventually, about a week afterwards, I found a locality in which 

 there was a small and late brood flying, and there managed to get 

 about a dozen good specimens. It probably emerges at Sarepta 

 about the first week in May. 



M. cinxia. — One of the most abundant and widely distributed 

 butterflies we met with. The form found at lalta and Novorossisk is 

 very normal, but at Sarepta all forms from the type to var. obscitrior 

 occurred. There was a succession of emergences during the whole 

 time of our stay, and perfect examples were to be obtained quite at 

 the end of it. 



31. phcebe var. aetheria. — Common and in good condition at 

 Sarepta during the first few days of our stay, after which it rapidly 

 became worn, 



M. aurelia var. seminigra. — A very remarkable form of a melitaea, 

 the genitalia of which are practically identical with Hungarian 

 M. aurelia, was found rarely in the "Tschapurnik Wald." This 

 form, which has superficially many aurelia characteristics, is much 

 darker than the type, both on the upper and under sides, and the 

 female especially is darker on the upper side than M. dictynna. It 

 agrees with M. aurelia var. seminigra, figured and described by Seitz 

 from specimens taken near Lake Baikal. Only three specimens were 

 captured, a male by myself on May 29th, and on June 6th a female 

 by each of us. This eastern form of M. aurelia is considerably 

 larger than Swiss or Hungarian examples of that species ; my male 

 and female expand respectively 44 mm. and 47 mm. as against 38 mm. 

 and 42 mm., the average size of my Hungarian and Swiss specimens, 

 and these again appear somewhat larger than the average, judging 

 from the fact that Mr. Wheeler in his ' Butterflies of the Alps,' 

 gives 32 mm. as the wing expanse of this species.
