ILLIBERIS. By Dr. K. Jordan. 15 



A. sieversi Alph. (= dejeani Oherth.) (3d). Forevving with a yellow streak behind cell from base sieversi. 

 almost to middle and a yellow spot on cross-veins; fringes yellow. Hindwing yellow, bordered with black, 



2. and 3. radials from cell or stalked. — West China; Kuku-nor. 



A. cuneonotata Leech (3d). Frons white; forewing with a j'ellow line in front of cell, besides the cuneonotata. 

 two spots of deversi; black border of hindwing broader. — West China, in July. 



A. delavayi Ohirth. (3d). Basal streak and discal spot of forewing united. — Rather frequent in delavayi. 

 West China, in June; Yunnan. 



A. aurulenta l^oiij. (3c). Forewing with 3 whitish yellow spots, the 1. and 2. close together, the aurulenta. 



3. large, kidney-shaped, distally of the cell. Hindwing yellow, bordered with black, a small black spot at 

 costal margin. — Mupin. 



A. sinica Alph. (3c). Forewing witli 3 whitish yellow dots in first third, and a double s\)o\ sinka. 

 distally of apex of cell. Hindwing yellow, with black border, which is broadest behind middle. — Se- 

 chuen. The only know specimen is said to be a ?, but is doubtless a c^ according to the antenna; however, 

 Alpheraky might easily have ascertained the sex bj' the frenulum. 



A. albofascia Leech (3g). Bodj- metallic. Forewing blackish, somewhat metallic at base; a straight, albofascia. 

 externally somewhat irregular, white band proximally of middle. Hindwing white, with back distal border. — 

 Ta-tsien-lu on the Upper Yang-tse-kiang, in July. 



19. Genus: Illiberis Walk. 



Tongue long. Palpus very short. Antenna in cf long-pectinate, the distal segments being usuallj- 

 dentate, in ? shortly pectinate or dentate. Hindtibia with 1 pair of short spurs. Veins from the cell, rarely 

 2. and 3. radials of forewing stalked; 1. radial of hindwing (vein 6 of Hereich-Schaefper system) present. — 

 Prof»-/.s-like insects, easily distinguished from Procris by the foretibial spur. As in that difficult genus we 

 are also in lUiberis not well acquainted with the distribution of the species. 



I. sinensis Walk. (3e). Antenna pectinate to tip in cf and ?, branches of ? short but distinct; shaft sinensis. 

 of antenna glossy green-blue; body black, with a feeble dark green gloss. Wings transparent; fringes 

 black; basal half of costal edge of forewing, the whole hindmargin, and on the hindwing the costal margin 

 more densely scaled black. 1. median of both wings proximally of cell-angle; cross-vein of hindwing 

 sharply angulate, the lower cell-angle projecting. Clasper of cf divided almost to the base into 2 long 

 narrow processes of which the ventral one is pointed, being very strongly chitinized. — Central and 

 West China. 



I. assimilis spec. nor. (3e). Entirelj' like the preceding except for the ventral process of the clasper assimilis. 

 of cT being replaced by a quite shoi't, verj- broad lobe which bears a conical tooth. — Gensan in Corea, 

 Central China, in June and July. 



I. rotundata ■'<pec. nor. (3e). Antenna of ? dentate. Forewing shorter and more rounded than in roiundata. 

 the previous insects, hind and distal margins of forewing more densely scaled, many scales of the upperside 

 3-toothed, fan-like; median veins of both wings nearer the cell-angle than in the previous species, cross- 

 vein of hindwing feebly angulate, the lower angle of cell httle projecting, 2. and 3. radials and 1. median 

 of hindwing about equidistant from each other. — Chang -Yang on the Yang-tse-kiang, in June. 



I. psychina Oherth. (3e). Antenna of cf rather shortly pectinate, the last 5 or 6 segments dentate, psydiina. 

 antenna of ? dentate. Abdomen above feebly green, below dark grey, especiallj- in cf. Wings blackish 

 grey, the scales pale, the fringes deeper black. 1. median of both wings close to angle of cell; lower cell- 

 angle of hindwing projecting. Clas])er of o^ broad, bearing at the ventral edge a large, triangular, 

 acuminate tooth. — Wladiwostock; Askold, from end of April; doubtless often confounded with the 

 following species. 



I. hyalina Stgr. {= consimilis Leech) (3 f). Antenna of cf pectinate, the last 10 segments dentate, hya/ina. 

 these simple in ?, the others dentate. Body and wings grej', somewhat yellowish, pale purple in side- 

 view, especially on the veins. Underside and on hindwing also the upperside at costal margin scaled 

 white; scales long, feebly bidentate, those of underside of both wings as well as those of upperside of 

 hindwing mostly non-dentate. Cell of forewing in proximal half more angustate than in the preceding 

 species, the subcostal and median veins contiguous; 1. median of hindwing far from cell-angle, 4. and 

 5. subcostals of forewing from a point or short-stalked. Clasper of cf broad, with simple, event)- curved
