TARACTROCEEA; ADOPAEA. By P. Mabille. 



the postmedian spots of cellules 3 and 4 arc placed near the centre of these cellules and cover their whole 

 hreadth. Mupin, West Chma; Tibet. 



Section B. 



Antennae diverse, but never curved in hoolc-shape, tiie tip curved, short or long, sometimes absent. 

 Tliird segment of palpi long, slender, vertical, often curved bacliwards, sometimes very short. Tiie cell of tlie 

 forewing always shorter than two-thirds the costa; vein 5 curved at the base and always near 4. ^ often 

 with a stigma, and always without costal fold. Hindtibia very freijuently with 2 pairs of spurs, but never with 

 a brush of hairs. 



33. Genus: Taractrocera Btlr. 



This genus is characterised by the club of the antenna having the shape of a flattened disc and 

 being without a pointed tip. The palpi curved backwards, their third segment thin and long, reaching 

 above the frons. (^ without stigma. 



The genus contains at least 11 species, which mostly occur in India and the Malayan and Pacific 

 islands. Only three species are found on Palearctic territory. 



maevius. P. maevius F. (= sogara Moore) (87 e). The spots of the wings small and white. Veins white on 



the underside of the forewing, very prominent; a spot in the cell and an angulate band of white spots 

 across the branches of the veins. North- Western Himalayas, and throughout India. 



danna. T. danna Moore. The veins the same, but not white, no white spot in the cell, but with a white 



stripe in cellule 1 b. North- Western Himalayas, at 2000 m and upwards. 



flavoides. T. flavoides Leech (87 e). Spots of the wings yellow. Hind wing beneath with the basal third 



yellow and with an almost square yellow spot below the centre of the cell. Omi-shan and Mupin, West 

 China. 



34. Genus: Aclopaea Bilherg. 



Widely distributed in the Old World, occurring from Europe to the Chinese seas. The genus 

 contains more than 12 species, of which 11 are Palearctic. It is recognized by the short antennae, whose 

 club is long, but lacks a pointed tip, further by the porrect palpi, whose third segment is needle-shaped 

 and obliquely erect. The wings are yellow in all the species, with black bands and spots. The following 

 key gives the principal characters which distinguish the species and by which they can be recognized. 



1. Veins on the hindwing beneath of the same colour as the ground 2. 



Veins black 6. 



2. Forewing of ^ with stigma 3. 



Forewing of ^J without stigma. Underside of wings uniformly pale ochreous. Base of the 



median vein of forewing outlined by a black streak which is continued beyond two-thirds of 



stigma. vein 2 A. stigma Stgr. (87 f). Turkestan. 



3. Stigma black and reaching to the base of vein 3 or beyond 5. 



Stigma black, ending at or before the point of origin of vein 3 4. 



4. Stigma very short and ending before reaching vein 3. Wings pale reddish yellow, narrowly 

 lineola. bordered with black. A. iineola 0. {= virgula Hbn.) (87 f). Europa and North Asia as far as 



Amurland. Stigma very feeble. Butterfly of lesser size. Wings above dark reddish yellow, broadly 

 ludoriciana. bordered with black, darkened in the ?. ab. ludoviciana Mah. In the Alps and the Auvergne. 



Stigma extending beyond the point of origin of vein 3 5. 



•5. Stigma black, reaching to the point of origin of 3, consisting of two portions, the one ex- 

 tending from 3 a little beyond 2 and the other terminating on 2, but being usually con- 

 hyrax. tinued by a stripe of scales of the same colour as the ground. A. hyrax Led. Anterior Asia. 



Stigma curved, continued from 2 across the point of origin of 3 and beyond the dis- 

 cocellular vein. Wings above pale brown, before the cell with a yellow, macular, patch, 

 acleon. which is more distinct in the cell. A. acteon Bott. (87 g). South and Central Europe, Ca- 



naries, North Africa und Asia ilinor. 



Similar, but the costa and the anterior half of the forewing pale yellow, absorbing the 

 hamza. yellow patch. A. hamza Oberth. (87 g). North Africa.
