B. olivescens Warr. (14 h). Antennal structure of fenestrata (14g). Hindwing with the tooth at 1st radial 
rather slight. In venation also similar to fenestrata, but with the 1st radial of the forewing scarcely stalked, 
the 2nd subcostal about opposite to the 5th, often anastomosing slightly with the 1st; costal further from sub¬ 
costal than usual, so that the point-anastomosis of the two is sometimes produced to a very short bar. Described 
from Fergusson Island, not rare in British New Guinea and has been found on Aru und Sudest Islands. 
B. anteplaga Prout (14 h). Pectination rather less long than in chrysolineata. Wings somewhat less 
irregular in shape; venation nearly as in hemisponsa, the anastomosis of the costal of the forewing stronger; 
characterized by the distribution of the white markings, which are mostly small, while one beyond the cell 
of the forewing is large, subquadrate. Founded on 3 <$<$ from the Khasis. 
B. albiplaga Warr. (= discolor Warr.) (15 a). In structure near olivescens, 2nd subcostal of forewing 
arising just before 5th. Readily known by the large white central spot of the forewdng. Naga Hills (type) and 
Sikkim; I have not found any racial difference in the Malayan discolor. 
B. vaga Walk. (15 a). Apparently a very rare species; I have seen no good specimens. By shape and 
structure a true Berta, but with more of the aspect of an Iodis. The type came from Sarawak, a second specimen 
(in coll. Swinhoe) from Sumatra. 
101. Genus: Comostolopsis Warr. 
A small genus, chiefly African, formed for the accommodation of those Comostola which have not the 
characteristic discocellulars of the latter (see Vol. 16, p. 44). On this basis, it has been necessary to attach a 
few of the Indian species to Warren’s genus; but as there exist also more or less intermediate forms, it might 
be better to re-unite Comostolopsis with Comostola. 
C. regina Th.-Mieg , founded on a defective $, without a head, is unknown to me. “15 mm. Pale 
rather bluish green, recalling the tone of P. pyrrhogona Walk. Distal margin of the 4 wings bounded by a fine 
red line, this bordering edged internally by a fine white line. Costa of forewing apparently white proximally, 
perhaps in the last (apical) third a little tinted with red. Underside pale white-greenish, with the fringe white, 
and without any trace of the red bordering. Abdomen above red from end to end, the sides bluish green.” 
Christmas Island. 
C. dyakaria Walk. (15a). Hintibia of rather strongly dilated, all the spurs excepting the inner proximal 
one short. More yellowish green than most Comostola, the red cell-spots quite small (punctiform), the lines 
obsolete or only very faintly indicated. Borneo (the original locality), Selangor and Luzon, always rare. 
C. albifimbria Warr. (15 a). Certainly very near dyakaria, perhaps a race. Structure the same; apex 
of forewing perhaps sharper; cell-spots, at least on hindwing, enlarged; the hindwing perhaps a trifle narrower. 
Hitherto only recorded from the Khasis, but the Seitz collection contains an example from Nepal, here figured. 
C. variifrons Prout (= acteana West ) (14 h). Named from the unusual frons — green, more or less varied 
with red and white. Hindtibia of <$ strongly dilated, the spurs short. Larger than the two preceding, the red 
terminal line vestigial, etc. Only known from Luzon; my type, in the Tring Museum, was unfortunately labelled 
“Parana, Entre Rios", so that I was misled into supposing it an aberrant Racheospila. Probably it may be 
a race, or even a synonym, of the following imperfectly-known species. 
C. simplex Warr. (14 a). Described as an Oenospilar, its transference to Comostolopsis will, it is to be 
feared, necessitate re-naming the African C. simplex (Vol. 16, p. 41), but it will perhaps prove possible to refer 
these Indo-Australian species to Cliloeres. To judge from the somewhat defective type (a $ from W. Java), 
it differs little from a small $ variifrons except in having a series of red terminal dashes; hindwing somewhat 
narrower. 
C. marginata Warr. (14 h) probably belongs here, though the is still unknown. Near dyakaria, but 
without cell-spots. Hindwing more fully rounded than in most of the preceding. Both the inner spurs of the 
hindtibia considerably longer than the outer. Kei Islands, only the type $ known. 
C. maculata Moore (= subtiliaria part. Hmps., nec Brem.) (14 h) differs from the rest in the large cell- 
marks, whereby is completed the development of the typical Comostola- pattern. Distinguishable by its large 
size and bluish tone; the discocellulars also separate it from all true Comostola. Besides Bengal, the original 
locality, it has only been found in other parts of the Himalayas, extending from N. AV. India to Assam; re¬ 
ported also from Szechuan.
