ACKODICBANIA. 93 



6fch vein long, but ending far from border of wing ; the 7th very 

 short, indistinct. 



Range, The only four known species are from Australia. 



Froggatt considers the genus a synonym of Leia. 



The two species referred here with some doubt to this genus are 

 distinguished easily thus : 



Thorax unicolorous, unmarked ferruyinea, sp. n., p. 93.. 



Thorax with a large oval black spot towards 



each side of the dorsurn incerta, sp. n., p. 93. 



46. (?) Acrodicrania ferruginea, sp. nov. 



? $ . Head orange-yellow. Eyes ovate. Palpi orange-yellow, 

 apparently four-jointed ; 1st short, 2nd and 3rd long, the former 

 the widest of all, 4th short, but the demarcation of the joints not 

 very obvious. Antenna? with the scape and basal half of flagellum 

 reddish orange, apical half of flagellum blackish. Thorax orange- 

 yellow, highly arched, microscopically pubescent. Scutellum 

 (damaged by pin) nearly as wide as thorax, short, blackish ; meta- 

 notum blackish. Abdomen black, closely but shortly pubescent; 

 apparently onlv 6-segmented, though a seventh may be easily con- 

 cealed below the last one ; segments towards the base more or 

 less dark brownish yellow ; belly similarly coloured. Legs orange- 

 yellow, a little tinged with brown. Femora blackish towards tips ;. 

 middle and hind tibia? with two rows of short seta?, which are 

 longest on the latter. (Fore tibiae missing.) Posterior tibia? with 

 long pale yellow spurs, tarsi a little darker. Wings pale yellowish- 

 grey. Venation mainly as in Johannsen's figure (Gen. Insect.,, 

 Fasc. 93, pi. 5, fig. 14), but the base of the 4th vein and the anterior 

 cross-vein, with the 3rd vein, are all of them more in a straight 

 line ; whilst the petiole of the 2nd posterior cell is not a strong 

 vein as shown in the author's figure, but is as weak as the 

 branches forming the fork. 



Length 3 millim. 



Described from a single specimen (which appears to be a female, 

 although no genital organs are visible) taken in the Khasi Hills, 

 Assam, 1000-3000 ft., x. 06. 



Type in the Pusa Collection. 



This species is referred doubtfully to Acrodicrania, as some dis- 

 crepancies are noticeable. The head is not sunk in the thorax ; 

 the abdomen has six, at most seven segments, not eight, as in 

 Skuse's description. 



47. Acrodicrania incerta, sp. nov. 



5 . Head pale yellow, with pale yellow pubescence ; vertex a 

 little darker. Proboscis obtusely conical, pale yellow ; palpi pale 

 yellow. Antennal scape pale yellow ; 1st joint moderately long,.
