 the head, very slender and filiform, 44-jointed ; first joint mode- 

 rate sized, oval, yellow beneath; second much smaller, rounded; 

 third still more slender, scarcely longer than the second, but 

 rather longer than the fourth, which, as well as the following 

 joints, is small and cup-shaped ; terminal joints rather more atte- 

 nuated. Theprothorax pitchy, opaque, granulose and setose, with 

 an obscure paler longitudinal line down the back. It is about 2^ 

 times longer than the head. Mesothorax pitchy, with the anterior 

 angles and two oblique spots on the disc obscure orange-coloured; 

 front of the metathorax chesnut-coloured. Abdomen black, each 

 segment with two small bright yellow spots placed longitudinally 

 on each side, as well as a slender longitudinal yellow streak; be- 

 neath black, with a broad irregular pale stripe down the middle. 

 Fore legs slender and elongated, the femur not thicker than the 

 coxa ; front of coxa pale luteous, behind pitchy ; femur both 

 outside and inside pitchy, with the upper edge and half of the 

 lower edge pale luteous ; spines pitchy, with the base pale ; tibiae 

 pitchy, with the upper edge dirty luteous; obtuse at the tip; 

 tarsi 5-jointed, terminated by two distinct slender curved acute 

 ungues and a moderate sized pulvillus ; four hind legs dirty 

 luteous, with pitchy setae; middle pair very short; femora pitchy 

 outside, tibiae with a dusky ring, about one-third of the length 

 from the base ; terminal joint of the tarsi pitchy ; ungues strong, 

 acute, much bent, furnished with a single very minute tooth on 

 the outer edge, at some distance from the tip. Wings almost 

 colourless ; principal veins pale brown ; stigma very pale greyish 

 luteous ; apical half stained with brown. All the wings with ten 

 oblique discoidal cells dependent upon the ordinary radial sectors, 

 slightly curved towards the costa of the wings ; fore wings with a 

 dark spot on the hinder margin, close to the base. 



Varies in having the coloured markings less decided, and the 

 general appearance more uniform ; and there are specimens of 

 this kind in the British Museum Collection, which have the cells 

 of the wings rather more numerous.
