DIASTALTICA.—ANACAMPSIS, 33 
Antennae 2, slightly serrate towards apex; basal joint without pecten. Labial Palpi long, smooth, recurved ; 
terminal and median joints about equal in length. Maaillary Palpi short. Haustellum well-developed. 
Ocelht present. Head and Thorax smooth. Forewings narrow at the base, somewhat widened outwardly, 
costa slightly arched near the base, apex scarcely depressed, pointed, termen sinuate, very oblique, tornus 
rounded: neuration 12 veins; 7 and 8 stalked, to costa; 2-6 separate, 2 remote from 3. Hindwings 1, 
costa straight, apex obtusely pointed, termen slightly sinuate, dorsum parallel with costa: neuration 
8 veins; 3 and 4 connate; 5 cubital; 6 and 7 connate. Abdomen smooth. Legs smooth; hind tibiae 
slightly haired above. 
This genus is separable from Acompsia Hb. (=Brachycrossata Hnmn.) by the 
position of vein F'W: 2, as also by its general structure and appearance. 
1. Diastaltica separabilis, sp.n. (Tab. I. fig. 29.) 
Antennae pale cinereous, annulate with dark brown. Palpi pale cinereous, Head and Thorax brownish grey ; 
face pale cinereous. Forewings dark bronzy brown, a pale aeneous band, commencing at the base of the 
costa, is dilated downward to the dorsum, and continued outward along it to the middle, where it 
is turned upward to the fold, joining the inner branch of a shining steel-grey furcate fascia, which, 
descending from the costa, scarcely beyond the middle, encloses an elongate, transverse, brown spot, 
near its outer side on the cell; this is preceded, halfway to the base, by an outwardly oblique, shining, 
steel-grey, metallic, cuneiform costal blotch; a sinuate band of the same colour commences with the 
costal cilia, suddenly angulated outward below them, and diffused along the lower half of the termen ; 
between the outer and the central fascia, as also on the dorsum between the forks of the latter, the dark 
ground-colour is thickly sprinkled with golden-brown scales; terminal cilia whitish cinereous, with a 
pure white patch below the apex, a dark brown line along their base ; costal and tornal cilia brown. 
Exp. al.18 mm. Hindwings dull brown ; cilia with a slight greyish tinge, especially toward the apex. 
Abdomen dark bronzy brownish grey, with a white ring around the base of the genital segment. Legs 
dark brown, with two broad white bands around the tibiae, and four smaller ones around the tarsi; spurs 
white.
