The subgenus Brachycola Warren ( — " Perixera Meyrick " Hampson, Faun. 

 Brit. Ind., Moths, iii, 446, 1895, ex err.), typified by A. absconditaria Walker, 

 of India and Malaya, consists of some six or seven Indo-Australian species, and 

 is characterised by having the hind tibia extremely short, with a tuft of red 

 hair and 3 long, curved spurs. The subgenus Pisoraca Walker (distribution 

 nearly coterminous with that of the genus) has the hind tibia of normal length 

 but with 3 spurs, and is represented in Fiji by one recently discovered species 

 near — perhaps a race of — A. compacta Warren, 1898, a species of which the type 

 was obtained in the Kei Is., though it has since been found to occur throughout 

 a wide area in New Guinea, as also in the Louisiade and Bismarck Archipelagos. 

 Another member of the genus, A. (Perixera) prionodes Meyrick (Tr. Ent. Soc. 

 Lond., 1886, p. 209, 1886), was described from a single $ from Fiji in the col- 

 lection of Dr. T. P. Lucas and may be a form of the variable A. pauper Butler 

 {Ann. Mag. Nat. Hist., (5), xx, 245, 1887) (Solomon Is.) = A. syntona Meyrick 

 (Tr. Ent. Soc. Lond., 1889, p. 487, 1889) (Port Moresby). In the subgenus Perixera 

 Meyrick ( = Phrissosceles Warren) it is the hind femur of the J which bears a 

 red tuft, while the tibia is normally formed, with a pair of terminal spurs. A 

 typical (Fijian) Anisodes, without appreciable secondary sexual characters 

 and with only terminal spurs on the hind tibia, is likewise a solitary of a race 

 or close ally of a widely distributed species (New Guinea and the islands east- 

 ward, as far as the Solomons) which I believe to be A. praetermissa Bastelberger 

 (Int. Ent. Zeit. Guben, ii, 38, 1908). I have not yet been able to examine the 

 type of the latter— a single specimen, apparently in poor condition. In 

 addition, some fifteen other Anisodes are known to me as occurring in the 

 Solomon Is. : one in the subgenus Zeugma Walker = Dizuga Warren (£ hind 

 tibia with 4 spurs), one in Brachycola, 7 in typical Anisodes, one in Crypsiplocia 

 Warren ($ with costal fold beneath), two in Plochucha Warren (^ with costal 

 fold above), one in Stibarostoma (vide infra), and two in Perixera. The genus 

 probably numbers nearly three hundred species, of which slightly over one-half 

 are Neotropical.
