Genotype, A. atricauda, Skuse ; by original designation. 



Head ovate, fore part flattened, situated cieej) in the thorax ; 

 front broad, the anterior margin produced into a small triangle 

 reaching the basal joints of the antennae ; eyes oval ; ocelli three, 

 of unequal size, arranged in a line on the front. Palpi prominent, 

 incurved, four- jointed ; 1st and 2nd joints robust, short, the 2nd 

 about twice the length of the 1st; 3rd joint much more slender 

 and a little longer than the 2nd ; 4th joint very slender, not the 

 length of the 2ud and 3rd taken together. Antennae cylindrical, 

 l)rojecting forwards, arcuated, about as long as or somewhat longer 

 than the thorax, 16-jointed ; 1st scapal joint cyathiform, about 

 twice the length of the 2nd, the latter cupuliform, both with short 

 setaceous hairs at the apex ; the 2ud joint generally with only one 

 strong seta ; flagellar joints cylindrical, with very short downy 

 pubescence. Thorax ovate, highly arched ; scutellum nearly as 

 wide as the thorax, too flattened to be semicircular ; metathorax 

 highly arched. Abdomen rather robust ; eight segments, the 

 eighth very short and generally hidden by the seventh ; in the male 

 flattened, claviform, with a moderate anal joint and forceps; in the 

 female robust, flattened, terminating in a short ovipositor provided 

 with two small terminal lamellae. Legs strong ; femora broadly 

 flattened; tibiae spurred, and having strong lateral spines on the 

 intermediate and hind pairs ; fore tibiae with a range of minute 

 spines on tlie outer and inner side, the spines on the latter widely 

 separated and few ; intermediate tibiae with tliree ranges on the 

 outer side and one on the inner side ; hind pair with two ranges 

 on the outer side. Wings longer than the abdomen, moderately 

 broad, with rounded-otf base ; microscopically pubescent. Ven- 

 ation A\ith rather an abnormal appearance. The auxiliary vein 

 short, ending in the costa at one-third of tlie wing, with the 

 subcostal cross-vein distinct, near its tip. The 1st longitudinal 

 nearly straight, ending at middle of wing ; 3rd vein originating 

 from near tip of 1st vein, at a right angle (like a cross-vein), 

 slightly bisinuate, short. Anterior cross-vein long, oblique, 

 forjning with the 3rd vein (after the bend) a bisinuate line. The 

 4th vein forked widely some distance beyond contact M'ith anterior 

 cross-vein, the 5tb widely forked before half its length, the 

 branches a little sinuous, the upper one detached at its base. The
