branch of the anal vein running out some distance, beyond 

 end of cubitus in the hind wing but one row of cells ; in fore- 

 wings one basal subcostal cross-vein. Pronotum extremely 

 slender in front, almost pointed; legs with very long hairs ; 

 hind tibia very much longer Lhan femora ; all tarsi extremely 

 short, basal joint no longer than second or third. 

 Type. — The following species : 



Nympliydrion delicatiiiu n. sp. — Pale ; pronotum with a faint, 

 darker median stripe ; antennae with black hair ; scutelli and anterior 

 lobes of both meso- and metanotum blackish ; abdomen with black 

 spot above on each segment. Wings hyaline ; fore-wings with five 

 black clouds, four of them on origin of four branches of radial sector, 

 and one on the stigma ; a fainter dot behind stigma, and one on 

 origin of first branch of the radial sector, and another on the last vein- 

 let connecting the radial sector and radius, near tip of wing. Vena- 

 tion pale, a number of cross-veins partly dark, and the forkings of 

 costal veinlets dark ; a reddish spot at extreme base of costal area. 

 Hind-wings with entirely pale venation, except on the stigma is a faint 

 mark, and one on last connecting veinlet between radius and radial 

 sector, and a faint reddish dot at base of costal space. Apex of both 

 wings acute ; in shape like Nesydrion ; a few cross-veins beyond end 

 of radial sector in both pairs. Expanse 55 mm. 



Type. — 9. From Herberton, Queensland, Aus. (Dodd). 



Nesydrion pallidum n. sp.— Pale yellowish; a median black 

 spot on face, a black line between antennae, vertex with two dark 

 longitudinal stripes, connected in front to a shorter, median black 

 line, behind with a black spot each side; antennae brown, with short 

 black bristles; pronotum pale, with a faint broad stripe through mid- 

 dle ; thorax and legs pale ; abdomen brownish above and toward the 

 tip. Body and legs with long white hair. Wings hyaline ; venation 

 wholly pale yellowish, stigma hardly indicated, some veins, in certain 

 lights are darker. Wings long, about the shape of A^. diaphanum, but 

 the costals more numerous ; radial sector in hind wings arises nearer 

 base than in that species, and the hind wings are rather broader in the 

 middle, so that a number of the veinlets from median are forked three 

 times before m.argin ; in both wings the radial .sector has ten branches. 

 Expanse 65 mm. 



Yype.— 9 . From Herberton, Queensland, Australia, 5th 

 February (Dodd).
