880 MR. H. J. ELWES ON THE BUTTERFLIES [NoV. 15, 



I have never seen C. erate from N.E. Asia, though it is recorded 

 by Bremer from Possiet Bay and by Murray from Japan. The 

 yellow form of 0. hyule, which is so like the female of C. erate, that 

 I could not tell them apart, has probably been mistaken for it. 



I would here take the opportunity of saying, in answer to Mr. 

 Butler's repeated assertion (see Ann. & Mag. Nat. Hist. ser. 5, vii. 

 p. 1 37) that G. helictha, Led., cannot be a hybrid, that I am assured 

 by Dr. Staudinger that the two species C. edusa and C. erate which 

 produce it do fly together in abundance at Sarepta on the Volga, and 

 that Kindernian, Becker, and Christoph have not once, but repeatedly, 

 taken them in copula. Mr. Strecker also tells me that hybrids 

 between Colias philodice and C. eury theme t^yc not uncommon in both 

 sexes in the United States, and that they look much like the Russian 

 hybrid C. helictha. 



P.S. Mr. Strecker writes me that he has trne erate from Japan 

 smaller than the Russian ones, the female darker on upperside of 

 hind wings, but the male has the unspotted border just like the 

 Russian examples. In a second letter he writes that " the Japanese 

 male C. erate is undoubted ; what I take to be the female, and which 

 I got along with it, is like the female Russian C erate suffused with 

 dark scales on the upperside of hind wing, whilst in C. simoda 

 (C hyale, var.j the clear lemon-yellow prevails." 



Colias melinos, Evers. Bull. Mosc. 1847, iii. p. 72. 



Found on the Schilka and the Amur by Radde, but appears very 

 rare in collections. It is nearly allied to C. phicomone. 



C. AURORA, Esp. t. 83. f. 3. 



Found at Raddefskaia, Blagovestchensk on the Ussuri, and other 

 places in Amurland ; but the females seem rare. There are two forms 

 of this sex, as in other species of this section of the genus — G. chloe, 

 Evers. Bull. Mosc. 1847, t. iv. figs. 3, 4, being the pale-coloured one ; 

 the other is extremely bright reddish orange. This species represents 

 C. edusa in North-eastern Asia ; no species of that section is known 

 to me in Japan or China at present. 



Terias ljlta, Boisd. Sp. Gen. i. p. 674 ; var. jjegeri, Men. 

 Cat. Mus. Petr. p. 84, t. ii. fig. 1 (1855). 



The variety found in China and Japan differs from the majority 

 of Indian specimens in having a narrower black border to the fore 

 wings, which is sharply interrupted near the hind margin in the 

 way shown in Menetries's figure. 



Some Himalayan and Khasia specimens have the band interrupted 

 in the same way ; but the Japanese examples can, as far as I have 

 seen, be distinguished. Menetries, by mistake, says that T.jaegeri 

 came from Hayti, where, of course, no such insect exists. It seems 

 common iu Japan, and is found at Shanghai.
