5. Pterotosoma biliueata spec. uov. 



ForeiciiK/ : lilac-grey, slightly tlark-specldcd ; the lines rnsty-browu ; the 

 first from one-third, and the onter nearly from two-thirds, of the costa, below 

 which they are somewhat curved, then vertical and parallel to each other to 

 a little beyond one-third and two-thirds of inner margin respectively, the outer with 

 a short projection below vein 4 ; a bilnnate brown blotch before margin between 

 veins 4 and 6, with a dark spot or two above and below. 



Hindwiiig : with similar lines, but the outer one plainly edged with ochreous 

 and bent on vein 5, both stopping short at vein 2 ; a black-edged yellowish sub- 

 marginal lunnle on each side of vein 4 ; fringe rather darker ; the fold whitish, the 

 tuft of hair yellowish and glossy. 



Underside paler, without any markings. 



Face and palpi black ; vertex and base of antennae cream-coloured ; thorax 

 and abdomen like wings ; the tips of the lateral tufts pale. 



Expanse of wings : 22 mm. 



1 S. 



Superficially the insect is not at all unlike E. simplex Warr. from India. 



Family DREPANULIDAE. 

 6. Oreta sub vino sa Warr. 



Along with a S example, agreeing exactly with the type lately described in 

 Nov. ZooL. X. p. 255, from Etna Bay, New Guinea, there has come another from the 

 Upper Aroa River, differing in that the dark tints of both wings are all dull rufous 

 brown, and the oblique line thin, inconspicuous, and curved, not straight and dark. 

 On the underside and in all other points this example agrees with the type. 



The two specimens, both SS, were taken in March 1903. 



7. Tridrepana fulvata Snell., ab. fasciata nov. and olivacea nov. 



This species, described in the first instance from Java by Snellen, afterwards 

 under the names alboiwtata Moore and ochrea Butler from India, and lumdata 

 Butler from the Solomon Islands, is widely spread. In the British Museum there 

 are examples from Hong Kong, and in the Tring Museum from Japan, Penang, 

 Sumatra, Bali and New Guinea. In the last locality it appears to be subject to 

 aberrational forms not met with, except in one solitary instance, elsewhere. The 

 form I c^XiJ'asdata consists merely in the area between first and second lines of the 

 forewings being filled up with fulvous, generally without any alteration in the rest 

 of the wing, though in one instance the deeper shade is diffused over the whole 

 wing and the markings become thickened and blurred. Only in one example, from 

 Gunong Ijau, has a similar development been noticed, as far as I know, out of 

 New Guinea. The other form, olivacea, has not presented itself before. Out of 

 9 examples just received from the Upper Aroa River, 3 (2 c?c?, 1 ?) are of the 

 typical form, 3 (2 (?<?, 1 ?) belong to ah./asciata, the remaining 3, all cJc?, are on 

 the upperside dull olive-brown without a vestige of yellow, with the markings 

 precisely as in the type, but the central fascia deeper, as in the ab. faiiciala. 

 Underneath the coloration is of the typical yellow, the only difference being that 

 the cell-spot, the costal portion of the outer line, and the fringes are olive-brown ;
