OF THE FAMILY URAPTERTGIDiE. 203 



tlie secondaries, especially beyond the middle. Expause of wings 

 68-73 millim.— Tokohama, Tokei, Nikko. Type B.M. This 

 species represents T. crocopterata in Japan. 



4. TniisroPTERTx ijebulosa, sp. n. — Near to T. delectans but 

 larger ; the markings, and. especially the external borders, mottled 

 with orange ; the yellow spots on the primaries forming a less 

 distinct band and less central ; there are also two blackish lines 

 across these wings as in T. croGopterata,\>ut less strongly defined, 

 and the discocellulars are dark; the disk of the secondaries is 

 always crossed by a more or less defined curved series of orange 

 spots, and the border is interrupted by a blackish patch ex- 

 tending into the tail. Expanse of wings 69-71 millim. — E. 

 India, Silhet. Type B.M. 



This species evidently represents T. delectans in India. It was 

 regarded by Kollar as a variety of T. crocopterata. It seems to 

 me, however, to come decidedly closer to T. prcmtoraria. Of 

 course it is possible, although hardly probable, that the three 

 are forms of a trimorphic species. They are all represented in both 

 sexes.

Xeeoptertx, gen. nov. (Plate IX. figs. 5, 6.) 

 This genus is so distinct from Urapteryx in neuration, that I 

 feel some hesitation in placing it here, the subcostal having 

 five branches, all being given oE from a long footstalk emitted 

 before the end of the cell — the first and second upon a separate 

 stem emitted from the main footstalk at less than a third the 

 distance between the cell and the apex ; the third and fourth 

 forming a short apical costal fork ; the fifth emitted from below 

 the maia stem soon after the emission of the two first branches : 

 lower radial emitted from the centre of the discocellulars, which 

 form an uneven concave line ; second and third median branches 

 emitted separately: neuration of secondaries as in the preceding 

 genus ; form of wings also very similar, but without the second 

 angulation of the secondaries : antennae of male ciliated.
