ACRODICRANIA. 93 



6tli vein long, but ending far from border of \\ ing ; the 7th very 

 short, indistinct. 



Mange. The only four know n 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 fernujinea, sp. n., p. 93. 



Thorax with a large oval black spot towards 



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



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



? 5 . 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. Antennae with the scape and basal half of fiagellum 

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

 yelloAV, 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 only 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- 

 yelloAv, a little tinged wiih brown. Temora blackish towards tips ;. 

 middle and hind tibiae w ith two rows of short setae, which are 

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

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

 grey. Venation mainly as in Johaunsen'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, 

 althougli no genital oi-gans are visible) taken in the Khasi Hills, 

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



Tt/pe in the Pusa Collection. 



This species is referred doubtfully to Aa^odicrania, 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 - Read 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,
