Halthia couaggaria Uuen. 

 The fact of Guenee's querviiig the ::.pt-iios as from the East Indies will account 

 for its non-recognition by all the authors who subsequently renamed it. There can 

 be no doubt that Gnenee's description refers to the form called Euryniede by 

 Motschulsky, that being the S of EurypyU Menfitr. In this Amur and Jajxm form, 

 as also in Felder's interrwptaria, the two large white blotches which form the central 

 fascia of the forewings, are never sejarated. but always coalescent, and the correspond- 

 ing fascia of the hindwing is always broad, and has its two edges parallel. In the 

 usual Chinese form represented by Walker's litlwsiar la, and in examples from Thibet, 

 the two blotches of the forewings are aUvays separated by the confluence of the black 

 from either side, and in the hindwing the fascia is sinuous, narrow, and sometimes 

 almost or quite obsolete. In both forms the ? ? , as a rule, show more white than 

 the (7 c?. The name should be erased fi-om Swinhoe's Catalogue of Indian Moths. 

 I have said above that Felder's intei'ruptaria agrees with the Amur and Japan forms, 

 rather than with the Chinese. A word with regard to this is necessary. In the 

 W. E. M., 1862, p. 39, the type is described as a S, and it is added, "This species 

 does not seem rare on the mountains of the province : Tsekiang." On Felder's 

 type label on the insect, Tsekiang is also given as locality ; but above the large type 

 label is a smaller one containing the word Japan. Now at the head of the article in 

 the W. E. M., p. 22, after speaking of the insects received fi-om China, the Felders 

 say, " we add a few insects sent by Dr. Siebold from Japan." It seems to me, 

 therefore, permissible to doubt whether the insect said to be from Tsekiang, and miide 

 the type of interi'uptaria Feld., really came from that place ; it is quite possible 

 that examples of the two forms came from both places, and that the type label 

 referring to an insect from one locality was inadvertently placed on the jjin of an 

 insect from the other. Moreover, the description agrees well with the Cliiuese form 

 iithosiaria Wlk., but does not agree with tlie jiarticular insect marked as tyi)e bv 

 Felder, and figured in the Novara Reise.

Omophyseta albiplaga sp. nov. 



Forewings black ; in the cj with two white spots near; the base separated by a 



black one ; in the ? the black shading predominates to such an extent that only two 



small white dots are visible, one close to the base, the other, wedge-shaped, at base of 



the cell ; a large oblong white blotch in the cell, and another below it between the
