HORISME. By L. B. Prout. 
351 
H. macularia Leech (Vol. 4, pi. 11 c). A moderately large species, the pale grey ground-colour faintly mucaluria. 
tinged with olive-yellowish, the macular markings of the forewing including an anterior subbasal band and 
a postmedian spot in cellule 3. Underside without the longitudinal streaks of the preceding species of Horisme. 
Hindwing more strongly crenulate. Founded on a from Omei-shan; known also from Sikkim, Assam and 
Formosa. 
H. flavofasciata Moore (37 f) was originally described from Darjiling as a Collix and has about the shape jlucojasi-lata. 
of several of that genus, but lacks the raised cell-spot and specialized midtibia and has the pale bands of the 
upperside greenish (fading to yellowish, hence the name). The underside resembles these of the weakest-marked 
Collix , though neither postmedian nor subterminal is at all macular. Variable in size. Extends through the 
Khasis to N. Burma. 
H. hirtivena Warr. (37 f). Considerably paler, median vein with linear patches of raised black scales, Mrlircau. 
costal shoulder of forewing roughly fringed; the numerous lunulate-dentate lines marked with blackish dashes 
on the veins; a pale spot just outside the cell. New Guinea, the type from Angabunga River. — ab. carneata curneata. 
Warr., founded on a pair from Biagi, has the body and the ground-colour of the proximal and distal areas of 
both wings flesh-colour. 
H. intrepida Prout (37 g) apparently represents hirtivena. on Kinabalu. Larger, the raised tufts of scales intrcpida. 
on the forewing rather less developed, the colouring, at least in the <J, more reddish, the underside showing 
some further differences. Both species show some structural deviations from typical Horisme : palpus longer, 
2nd joint with long-projecting hairs above and beneath; a strong pale anal tuft in the ; hindwing with a slight 
approach to the Coenocalpe shape of the discocellulars. 
H. erythroides sp. n. (37 g). Somewhat less robust than hirtivena , the genitalia a little less large. Color- erytliroidcs. 
ation darker and in places more suffused with reddish, more recalling on the upperside hyperythra Hmps., but 
retaining (or even accentuating) the pale patches just outside the cell and again outside the post median which 
are shown in hirtivena-, the raised scaling on the median vein apparently wanting (the wings here unfortunately 
little rubbed); longitudinal dark streak from lobe of postmedian to termen intensified. Mount Tafa, 8500 feet, 
February 1934 (Miss L. E. Cheesman), the unique type a in the British Museum. 
H. angustipennis Warr. (37 g). Probably related to hirtivena, but without the long-projecting hair of anyustipen- 
the palpus, the wings much narrower, without raised scales. Further distinguishable by its more whitish colour 
and somewhat less strongly dentate hindwing. Angabunga River (type), Biagi and Mount Goliath. 
H. ustimacula Warr. (37 g). Almost as narrow-winged as angustipennis but considerably darker, especi- ustimacula. 
ally the posterior part of the hindwing. Abdomen more robust, somewhat tufted laterally, blunt at tip. Anga¬ 
bunga River, 2 (§<$. 
H. hyperythra Hmps. (37 g). Generally smaller than flavofasciata , hindwing much less deeply crenate; hypcrthyra. 
colour much browner, inclining to reddish, more uniform. Underside strongly marked, both wings with cell- 
spot, strong band-like postmedian and more or less interrupted or macular subterminal; the postmedian on 
both wings, but especially on the hindwing, is indented near the costa and markedly angled outward before 
the 1st radial; these markings may be blackish or more reddish, but are always very characteristic. The type 
though this was not specified in the original publication — is from the Nilgiris; distributed from Ceylon to 
N. India, Pahang, Luzon, Borneo and Java. catalalia subsp. nov. is rather darker and less reddish, the lines catalalia. 
(or bands) on the underside broadened and heavily blackish, with the postmedian of the hindwing very acutely 
angled. Formosa (Wileman): Rantaizan (type) and Arizan. Also on Kiushiu and the Riu-kiu Islands. 
H. invicta sp. n. Although the is unknown, the position of this species cannot be in doubt. Expanse invicta. 
35—36 mm, larger than the largest hyperythra , the forewing relatively broader, the hindwing more crenulate, 
thus nearer in shape to boarmiata, to which it further assimilates in the much less bent postmedian of the fore¬ 
wing, particularly noticeable on the underside, where, however, it does not arise from a darker spot as in boar- 
miata. Scheme of markings otherwise almost exactly as in hyperythra , the tone similarly reddish, the underside 
even more suffused with vinaceous-cinnamon than in hyperythra , the course of the broad postmedian of the 
hindwing almost exactly as in that, though with a slight additional indentation at the 2nd radial. Korintji, 
W. Sumatra 7000 feet (Robinson & Kloss). 2 $$ in the Tring Museum. 
H. praemaculata Prout differs from the Indian olivata in that the forewing is broader, the termen consid- pmemacu- 
erably less oblique anteriorly than posteriorly, roundly bent about the 3rd radial, cell-spot obsolete above, 
rather less large than in olivata. beneath; lines weakened, costal spots remaining strong, a small basal-costal 
patch substituted for the proximal streak of olivata. Fakal, Burn, only the type known.
