204 CILIX; ORETA. By Dr. E. Strand. 



green with a red dorsal band edged with j^ellow, and with two red lines. Pupa purple-brown with white pubes- 

 cence. — Widely distributed in India, also in West China. 



C. Proboscis and frenulum absent or obsolescent. 



(Genera 13 to 15). 



13. Genus: Cilix Leach. 



Apex of forewing not sickle-shai)ed; on the hindwing veins 7 and S anastomose .so as to form an elongate 

 basal cell, the two end-branches behig on a long common stalk. On the forewing 6 and 7 originate from the angle 

 of the cell, 8, 9 and 10 are stalked. Frenulum vestigial. Antennae of $ with short bipectinations to the apex, 

 of the 9 with strongly reduced pectinations. Hind tibiae with middle and end spurs. At rest the wings folded 

 in steep roof-shape. — Larva like that of Drepana. 



glmicaki. C. glaucata Scop. (= spinula Schiff.) (48 d). White, thorax posteriorly blackish brown. Forewing 



with grey median band widened posteriorly, which does not reach the costal margin and is posteriorly inter- 

 mixed with violet-grey and lead-grey. Some of the veins are silvery white in the median band. On the inner 

 side the median band is bounded by faint olive-brown. Before the margin a row of small triangular grey spots. 

 Margin of hindwmg darkened with grey. 24 to 27 mm. South and Central Europe, also in Southern Sweden; 

 further in North Africa, Asia Minor, Syria, Armenia, Kashmir, the Himalayas, China, Amur, Ussuri, North 

 America. April and May, July and August; in the South apparently in tljree broods. The specimens from 

 the Himalayas differ in that the palpi are absent, the hind tibia has only one pair of spurs, and vein 7 of the 

 forewing is curved upwards, entirely or almost entirely anastomosing with 8, 9 and 10; this form, perhaps 

 depali)ala better regarded as a distinct species, I name depalpata subsp. nov. — asiatica Bang-H. (48 d), from Asia Minor, 

 asmtica. has the forewing almost uniformly white, with only a small triangular brown spot in the median area at the 

 inner margin. There is a specimen like this before me from Ain Draham in Tunis from coll. Seitz. — Larva 

 reddish brown with two pointed protuberances on segment 2 as well as 3, the posterior ones being larger 

 and white in colour at the tip; segments 11 and 12 each with two very small similar projections. On the anal 

 segment a sharp point and in front of it a small wart. Head with two small elevations. The median seg- 

 ments sometimes bear a light spot with a darker spot dorsally. 18 mm long. On Blackthorn, Plum and Haw- 

 thorn. June, August and September. Pupa light brown with bluish wing-cases, in a cocoon between leaves. 



14. Genus: Oreta Walk. 



Distinguished from the preceding genus by the forewing being produced at the apex, the sickle-shaped 

 tip, however, being roimded; vein 6 originates at the apex of the cell, 7 and 8 are stalked, likewise 9, 10 

 and 11, 9 anastomoses with 7 and 8, thereby forming an areole. Legs clothed with long hair. The antennae 

 may be serrate in both sexes, or bipectinate in the ^. 



externa. 0. extensa Walk. (22 i). Yellow, head and legs red. Wings more or less suffused with reddish brown, 



the yellow ground-colour iisually predominates in the basal area of both wings and in the marginal area (with 

 the exception of tlie apex of the hindwing). Both wings with white discocellular stripe, and sprinkled with 

 dark dots. Forewing with yellow oblique line from the apex ((J) or shortly before the apex (?) to the inner 

 margin, a dark spot at the anal angle and sometimes a small similar one at the apex. Occurs throughout 



suffusa. India, likewise in Java, according to Swinhoe (1892) also in Japan. — suffusa Walk. (22 i), described from 

 Ceylon, is a darker, more brownish form; the yellow ground-colour is almost entirely confined to the basal 

 area and oblique line. ,^ 38 to 43, '^ 40 to 54 mm. — The larva, in Java, lives on a species of Ixora, in April 

 and May; according to Moore's figure (1859), which is not good, it appears to be light with darker oblique 

 smears, the ,,tail" with black and pale rings. 



oUusa. 0. obtusa Walk. (22 i). ,^: Forewing with a narrow reddish brown band from directly below the apex 



of the wing to the middle of the inner margin, the line being slightly convex proximally and separating an 

 inner or anterior brown portion from an outer or posterior yellow one. Both wings with pure white discocellular 

 stripe. Forewing with two black costal marginal spots. Head and legs scarlet. In the ? the yellow colour 

 is suffused with greyish brown, and the proximal area of the wing is not darker, or only slightly so, than the 

 distal area; the oblique line of the forewing is less curved. (J 40, ? 48 mm. India, also iii Kashmir. — Accord- 



vafama. ing to MooRE (1865) and W.\rren (1899) vatama Moore is a distinct species, which is said to be distinguished 

 by the curved oblique line of the forewuig (according to Warren this is straight in obtusa) and the sharply 

 marked difference between the light and dark portions of the underside of the wing (in obtusa nearly uniformly 

 lirownish red); moreover, the antennae of obtusa and vatama are said to differ (but Warren mentions at the 

 same time that the tj'pe of obtusa has no antennae). As obtusa was erected for a $ and vatama for a (J alone 

 and the specimens of vatama known to me are all (J (J and those of obtusa $9 1 am mclined to agree with 

 obliquilinea. Hampson in regarding the two forms as sexes of one species. — According to Warren obliquilinea Hamps.
