BUTTERFLIES FROM THE INDO-MALAYAN REGION 393 



Hind wing pure white, the costa, apex and abdominal margin narrow- 

 ly fuscous ; a small fuscous spot at the apex of the discoidal cell, 

 another of the same size near the middle of the first median 

 interspace, and a much larger one in the middle of the submedian 

 interspace. Head and thorax above fuscous, abdomen anteriorly 

 fuscous, but the four or five posterior segments, as well as the 

 extreme tip, ringed with pure white ; hody beneath grey. 



Near to T. minuta, Moore (Lep. Cey., vol. i, p. 176, pi. lxviii, 

 figs. 4, 4a (1881)), from which it may at once be known by the 

 large white patches on the upperside of the hindwing and the 

 terminal segments of the abdomen being ringed with white. It is 

 evidently allied also to the Heteropterus ? {Sferopes) scopas of 

 Staudinger ("Iris," vol. ii, p. 161, pi. ii, fig. 12, wale (1889) ), from 

 Palawan, from, which it may be known on the upperside by 

 not possessing three considerable-sized spots placed in the form 

 of a triangle on the middle of the disc ; the hindwing also in 

 H. ? scopas does not appear to be blotched with white ; on the 

 underside the hindwing is a good deal like T. tripura, but the latter 

 lacks the black marginal spots present in H. ? scopas. Furthermore, 

 T. tripura is even more closely allied to the Heteropterus ? catoleucos, 

 also of Dr. Staudinger, from Palawan (1. c., p. 162, pi. ii, fig. ]3^ 

 male (1889) ), but lacks the one (or two) subapical spots present 

 in the forewing of that species, and the white area of the hindwino- 

 is far less extensive on both surfaces, but esj:>ecially so on the 

 underside. 



With regard to the genus Sferopes, Boisduval, used b}^ Dr. Staudinger 

 for one of the two species above referred to, it cannot be used for 

 Lepidoptera as it is preoccupied in CoJeoptera. The type of the 

 genus Heteropterus, Dumeril, is morpheas, Pallas, which occurs in 

 Europe and Northern Asia, and can have, I think, nothing in 

 common generically with minuta, scopas, catoleucos, and tripura. 

 For the present all these species had better, perhaps, remain in the 

 genus Tagiades, in which Mr. Moore has placed minuta, the first- 

 described of this group. 



Described from a single example in Mr. H. J. Elwes' collection 

 captured by Mr. W. Doherty in the Perak State, Malay Peninsula, 

 in Januarv-Februarv, 1890.
