PIDORUS. By Dr. K. Jordan. 
oo 
E. xanthina spec. nov. Like the preceding species; veins and transverse band of the forewing grey- xanthina. 
3 ^ellow; hindwing yellow; marginal band as in the forms of the preceding species broad anteriorly, sharply 
contrasting with the yellow area. — Cambodja; 1 ? in the British Museum. 
E. mirifica Swinh. (6e). Body purple-black, slightly metallic green, occiput and pronotum red . mirifica. 
Forewing blackish brown, the veins yellow-grey, an anteriorly broad, posteriorly linear yellow-grey trans¬ 
verse band from the costal margin almost to the hindmargin. Hindwing brown-black, with slight bluish 
sheen. — Siam; in the British Museum. 
37. Genus: Pidorus Walk. 
Broad-winged, black or black-green forms, with yellow or white band on the forewing. Frons 
much less projecting, and not so pointed as in Eterusia. The 1. and 2. subcostals of the forewing free, 
3.—5. subcostals stalked, the 1., 2. and 3. radials from the cell, the 1. median about midway between the 
2. median and the 3. radial; in the hindwing all the veins from the cell, or the 2. subcostal and 1. radial 
stalked, upper angle of the cell mostly projecting somewhat beyond the lower, distance from the connecting 
vein (the 1. subcostal) to the upper angle of the cell less than from the 2. median to the lower angle. 
Indo-Malayan, one species distributed northwards to Japan. 
P. glaucopis. Body blue-black, the occiput all round and the vertex red. Wings brown-black, 
somewhat purple, beneath striped w 7 ith blue; forewing with a white band from the costal margin to the 
anal angle. North India to Japan. — The form from North India, Burma and Tonkin has on the underside 
a blue band before the distal margin: glaucopis Drury rubrocollaris Goeze ) (6f). — In atratus Bilr. glaucopis. 
(vol. II, 2c), from South China to Formosa and Japan, this band is wanting. — One of the commonest atratus. 
species, which occurs in North India up to 5000 ft., but is most abundant at lower elevations. 
P. constrictus Walk. (6f). Black-green, the occiput all round red like the base of the prothorax, constrictus. 
margin of the frons, palpi, breast, underside of the abdomen and the legs dirty yellow-grey. Forewing 
more elongated than in P. glaucopis, distal margin much shorter, green-black, with pale yellow band from 
the costal to the hindmargin, reaching the latter just before the angle, its distal edge touching the tip of 
the cell, faintly edged with blue. Under surface striped with blue as in P. glaucopis, with a blue band 
before the distal margin, the yellow band of the forewing somewhat broader than above, the 3. subcostal 
distal to the 5.; upper angle of the cell less projecting than the lower. — Borneo, Singapore. 
P. gemina Walk. (vol. II, 2b). Thorax and forewing black-green, breast metallic blue and under- gernina. 
side of the abdomen metallic green, palpi, occiput and vertex red. Forewing with yellow band, edged 
with green-black, from the costal margin to the hinder angle. — North India; Burma; Tonkin; Cambodja; 
Hainan; Hong-Kong. 
P. leno Swinh. (6f). As the preceding, palpi and vertex not red, underside of the body and the leno. 
palpi in the cT yellow-grey, in the ? the palpus yellowish, the breast metallic green, the abdomen green- 
black. Band of the forewing not quite reaching either costal margin or hinder angle, apex of the hindwing 
yellow like the band; the long anal clasper of the cf is woolly. — Assam; Hainan. 
P. corculum Btlr. (= flavofasciatus Pagenst.) (6g). Collar not red; palpi, coxae, underside of the corculum. 
femora and the margins of the ventral segments white. Forewing with yellow band. Hindwing beneath 
with blue band before the distal margin. — Java; Sumatra; Nias; Malacca; Borneo; Palawan. Larva 
light brown, tubercles yellow, head and prothorax black. 
P. circe Pl.-Sch. (= metallica Walk.) (6f). Body blue-black. Forewing with green veins, or entirely cine. 
green; a curved band yellow: hindwing brown-black, a costal spot before the apex yellow, a band before 
the distal margin blue. — Assam; Sikkim. 
P. albifascia. Similar to the preceding species, forewing black, with slightly green veins, band 
white, with yellow costal spot at the innerside; hindwing with yellow costal spot just before the end of the 
cell, apex of the wing slightly bluish. Assam; Burma; Tonkin. — In albifascia Moore (6g). from Assam albifascia. 
and Burma, the inner margin of the band crosses the cell proximally to the 1. median, and the band is 
posteriorly about 4 mm. distant from the end of the 2. submedian. — In steleus subsp. nov., from Tonkin, steleus. 
the band has a somewhat more distal position and the costal spots are deeper yellow. 
P. cyrtus spec. nov. (6g). ?: head as in gemina. Palpus dirty yellow-brown. Forewing above black, cyrtus. 
the veins dark green; a curved yellow band from the costal margin to the hinder angle, with pale rose- 
coloured sheen, very narrowly blue at the margins. Hindwing brown-black. Beneath both wings black, 
with faint blue submarginal band. — Hainan, found in June; 1 ? in the Tring Museum. 
P. bifasciata Walk. (6g). Black-brown, slightly greenish; underside of the body earth-brown; hind- bifasdata. 
margin of the head red. Forewing 13 mm. long, a straight yellow band, somewhat irregular at the edges,
