LEUCESTHES; HEMISTOLA. By L. B. Prout.

95. Genus: Lieucesthes Warr. 
Probably also related to Euloxia. Characters nearly as in Mixochroa, but the palpus more smoothly 
scaled, the forewing narrower and with a very strong pearly gloss. Only one species known. 
L. alba Swinh. (— margarita Warr.) (14 c). Unmistakable through its white head, body and wings alba. 
and the strong gloss of the wings. West Australia. 
96. Genus: Heinistola Warr. 
An ill-defined genus, at present embracing most of the genera of Hemitheinae which have lost the 
frenulum in both sexes and possess none of the other specialisations of shape or structure which refer them 
definitely to other genera (see Vol. 4, p. 30, Vol. 16, p. 43). Antenna of and usually of $ pectinate. Hind- 
tibia with all spurs, the E rarely with hair-pencil. Forewing with termen entire, 1st subcostal from cell, rarely 
with the anastomoses of Euloxia-, hindwing usually angled at the 3rd radial, but seldom sharply so. 
A. H indwing not appreciably angled; antenna of $ not pectinate. 
H. efformata Warr. (15 a). Formerly regarded as an aberration of the following, with the white cell- ejformata. 
marks obsolete; but as the termen of the hindwing does not show even the faint bend which, on careful in¬ 
spection, is discernible in that species and the line of the forewing is less fine, non-crenulate and more distally 
placed, it must be a separate species. Sikkim, only a few' $<3 known to me. 
H. loxiaria Guen. (= dispartita Walk.) (14 c). So far as can be made out from a few (and mostlyimper- loxiaria. 
feet) specimens, lotciaria (the type a of which Gttenee did not know the patria) and dispartita (a $ — not “<$” 
as published — from “Hindostan”) are sexes of one and the same species, briefly described in Vol. 4, p. 31; in 
any case they are extremely close allies and belong to the Punjab and Kashmir. Oberthur (fig. 3212) has 
already figured Guenee’s type, but misses the characteristic white cell-spots and other details; we have there¬ 
fore re-figured the same specimen. The antenna of the $ is noticeably serrate. — ab. cymaria Hmps., from cymaria. 
Simla, has the w'hite cell-spots enlarged but is scarcely worthy of a name. 
H. fletcheri sp. n. (14 c). Extremely similar to dispartita, of which I first supposed it a race, scarcely fletcheri. 
distinguishable except by its larger average size (28—35 mm against 25—31), the slightly more delicate texture 
of the wings, their more bluish green tone (closely like that of average chrysoprasaria Esp.) and the somewhat 
weaker or narrower cell-marks. Since, however, the joints of the $ antenna project quite markedly in dispartita 
and not at all so in fletcheri, it must certainly be a separate species. Kashmir: Gulmarg, 8500 feet (T. B. 
Fletcher), a good series collected in July 1931, besides a few at the same season in 1923; type $ hi Mus. 
Brit. — subcaerulea form. nov. is a small form (seasonal?), expanding only 22—27 mm, of a more bluish colour, subcaeru- 
apparently abundant about Srinagar, where Prof. Fletcher obtained a very long series in August and Sep- ^ ea - 
tember. A $ from the same locality, dated 8 June, unfortunately discoloured, is of about normal size but seems 
to share with subcaerulea the bluer coloration. 
H. malachitaria Prout (14 c). Colour of subcaerulea, antennal pectinations shorter, hindtibia perhaps malachi- 
more slender, apex of forewdng less pointed, the white line weaker. Kukli, N. W. India, only the type E known. taria. 
H. christinaria Oberth. (Suppl. 4, pi. 1 e) is very distinct in the strongly angnlated postmedian line, christina- 
as well as in the presence of a distinct antemedian on both wings. Structural characters, kindly supplied by rm - 
Dr. Wehrli, refer it to the present genus. Chinese Tibet, 1 $. 
B. Hind wing well angled; antennae of $ simple. 
H. rectilinea Warr. (14 a). Differs from rubrimargo in the shape of the hindwing (which is more sinuous rectilinea. 
before the angle), in the almost straight postmedian line and in the stronger dorsal maculation of the abdomen 
(red, with the white streaks almost as long as the segments). The white terminal line is on the wing, not (as 
in rubrimargo) on the base of the fringe. Khasis, only the type $ known. 
H. rubrimargo Warr. (12 g). The commonest and best-known of the group. Not very variable, but rubrimar- 
the red spots at the hinder end of the lines can be almost entirely obsolete; that at the end of the postmedian v°- 
seems never to be so large as in the type of rectilinea. Palpus of $ rather long. Sikkim (loc. typ.) to Assam 
and again in Szechuan and on Formosa. 
H. fuscimargo Prout (14 c). Larger, with stronger dark cell-dots, the fine terminal line brown, not red; fusebnargo. 
usually there are slight indications of some red scaling at the proximal edge of the postmedian line, at least 
as minute vein-dots in its angles, but the red spots at the hinder end of the lines are not developed in any spe¬ 
cimen known to me. Palpus of $ less elongate than in rubrimargo. Sikkim (loc. typ.) and Assam.
