been subjected to. A second brood was abundant during the last few 

 days of May ; I should call these intermediate between the type and 

 var.' hellidice. 



Anthocharis belia. — A very pretty form with light grey tips to the 

 superiors was not infrequent at lalta ; the second brood became 

 plentiful at Sarepta by June 7th ; the upper sides of these are 

 similar to South European var. ausonia, but the under sides are 

 much darker, and closely resemble var. simplonia. I suppose they 

 should be called var. nraleiuis, Bartel, but they do not seem quite to 

 agree with his description of this variety. 



Euchloe cardamines. — A remarkable race was abundant in the 

 " Tschapurnik Wald " at the end of May ; they are much larger than 

 any I have seen from elsewhere, expanding up to 56 mm. The average 

 expanse of British and European specimens I make to be about 

 42 mm., and Mr. Wheeler, in his ' Butterflies of Switzerland,' gives 

 the same expanse. It will thus be seen how large this steppe form 

 is. The discoidal spot on the superiors is smaller than in the type, 

 and the under sides of the inferiors have very much less green. I 

 propose for this local race the name of var. volgensis, n. var. Typical 

 specimens were not infrequent at lalta, and in the woods between 

 there and Sebastopol ; it was also seen at Novorossisk. 



Zegris eiqjheine. — Not uncommon on the railway banks at Sarepta 

 during the first day or two w^e were there ; but, as happens in the 

 case of the Spanish race, it disappeared all at once, and not a speci- 

 men was seen afterwards. 



Lejitosia sinains. — Frequent at lalta, also at Novorissisk, and 

 one or two were seen in the " Tschapurnik Wald," at Sarepta. The 

 examples I brought home are very typical first-brood forms. 



Colias hyale. — Fairly numerous at Sebastopol ; abundant at 

 Novorissisk, and common at Sarepta at the date of our arrival, and 

 a second brood was flying there in the middle of June. 



C. erate. — This beautiful eastern species was abundant at Sarepta at 

 the date of our arrival, and from its condition then it had evidently 

 been flying some time. There was a series of emergences during the 

 whole time of our sojourn, and it was particularly abundant during our 

 last few days. The male is a particularly vigorous creature, flying at a 

 tremendous pace, and very difficult to capture, unless one can intercept 

 it in its course. The female is much less active, and frequently settles 

 to suck at flowers. The white form of the female, var. iMllida, was 

 almost as abundant as the type. At Sarepta G. crate frequented 

 chiefly the railway banks and cuttings, no doubt being influenced 

 largely in its choice of locality by the luxuriant growth of leguminous 

 plants on which the larva feeds, which are to be found there ; the 

 male was, however, to be seen at intervals, wildly scurrying along, 

 all over the surrounding country. I was successful in breeding an 

 imago from an ova obtained from a captive female. 



C. edusa. — Common in the Crimea and at Novorossisk. At 

 Sarepta I saw one or two worn examples on May 21st, and there was 

 a second brood which I saw first on June 9th ; these were not by 

 any means abundant. 



Colias hybrids. — It has long been noted that, when two or more 

 of certain species of this group are found on common ground, inter-
