616 Pieter C. T. Snellen on a 



Genus Heterocnephbs, Led., Wien. Ent. Mon., vii., 

 p. 402. 



173. Heterocnephes reniferalis, nov. spec. 



Three males and a female of 26 — 28 mm. expanse. 



Allied to acamasalis (Chabula), Walker, Moore, Lep. of Ceylon, 

 p. Sn ^ strangulalis, Snellen, Tyds., 23, p. 224; 27, p. 35, pi. 8, 

 f. 1, la; all generic characters and the shape of wings the same, 

 but a larger insect, the ground colour more brownish, the clear 

 part is not so pure white, though also a little iridescent, the second 

 large white spot of fore wings more distinctly reniform ; no 

 white fascia after the white line behind the said spot ; on hind 

 wings the dark discal streak confluent below with the discal fascia, 

 and after the white line, which is limiting this fascia behind no 

 white spot, but an ill-defined pale yellowish patch. Labial palpi 

 whitish, with two black spots ; front black, white-edged. Thorax 

 brownish grey, with longitudinal white lines. Ground colour of 

 wings fuscous, darkest in the middle, pale along costa of fore wings ; 

 basal fourth of fore wings with two or three (the second wanting 

 or indistinct in two specimens), outwardly oblique, straight white 

 lines ; after the last an elongated white fascia, extending from 

 the costa to cell 1 6, in one specimen connected by a pale luteous 

 line with the inner margin ; beyond the middle a large, reniform, 

 black-margined, iridescent white spot, extending from costa to 

 vein 2, and between it and the first fascia a luteous C on vein 1 ; 

 after the reniform spot a black-margined transverse white line, 

 widening at the costa and also a little at inner margin, as in 

 acamasalis, but less undulated; marginal fourth of wing pale 

 olivaceous grey, uniform; marginal line black. Basal half of 

 hind wings white, a little transparent, with an indistinct black line 

 along inner margin, a black discal streak, connected with an 

 undulated black discal fascia by means of a projection of this in 

 cell 2 ; behind the black fascia is a white discal line, running from 

 two-thirds of costa to anal angle ; opposite the discoidal cell it is 

 narrower ; marginal third of wing fuscous, with an elongate pale 

 luteous patch, pointed towards anal angle. Fringes yellowish 

 white, with an interrupted black discal line, which is diffused at 

 the apices and in cells 2 — 4 of all wings. Abdomen dark grey, 

 indistinctly marked with white. Under side of wings marked 

 nearly as the upper side, not so distinctly. 



The genus Chabula, Moore, may be united to Hetero- 

 cnephes ; there are no perceptible differences. 



Sikkim; Moller.
