374 HETEROCERA. 
DYSOPTUS Wlsm. 
(Svcorros=hard to see.) 
Type: Dysoptus probata Wism. (Tab. X. fig. 25.) 
Antennae (¢ ) 3, serrate and shortly biciliate. Labial Palpi stout, recurved nearly to the vertex ; basal joint 
well-developed, median as long as terminal—all closely clothed beneath. Maxillury Palpi and 
Haustellum obsolete. Head and face smooth, somewhat loosely scaled. Thorax smooth. Forewings 
rather broad, rounded at apex, termen oblique, tornus rounded : neuration 11 veins (10 absent); 7 to 
‘costa; 8-9 stalked, rest separate. Hindwings 1, termen obliquely rounded: neuration 8 veins, all 
separate. Abdomen (? ) rather stout, with long silky clothing on anal segments. Leys (broken). 
This species appears to be allied to Lampronia Stph., from which it differs in the 
absence of the haustellum and labial palpi, and also in having but eleven veins in the 
forewings, 8-9 being stalked. Dysoptus agrees with Greya Busck in having only 
eleven veins, but differs in 7-8 being stalked and also in its smooth head. 
1. Dysoptus probata, sp.n. (Tab. X. fig. 25.) 
Antennae and Palpi dull ochreous. Head brownish ochreous. ' Forewings testaceous, with a strong lilac 
gloss and several washed-out pale whitish ochreous spots and specks; a small one on the upper edge 
near the base, a larger one, before the middle of the costa, reduplicated obliquely outward beneath in the 
direction of a larger discal spot of the same colour near the end of the cell—this crosses the cell, another 
spot occurring below it slightly nearer to the base; a little beyond the cell a series of small obscure spots 
is curved outward and backward nearly to the outer extremity of the fold; halfway between the medio- 
costal spot and the apex is another small costal spot, while below and beyond it, opposite to the apex 
between veins 6 and 7, is another spot; an elongate triangular streak lies on the middle of the termen, 
the cilia opposite to it being of the same pale colour, as are also those at the extreme apex—except for . 
these two patches the cilia partake of the darker ground-colour of the wings. Exp. al. 16mm, Htnd- 
wings almost exactly the same colour as the forewings, although in some lights they appear a little 
prowner, these are also speckled with pale whitish ochreous, a semicircle of spots occurring beyond the 
end of the cell and an ante-apical spot between veins 6 and 7; cilia concolorous with the wing, with two 
pale patches on either side of the apex corresponding with those of the forewings. Abdomen testaceous, 
the anal tuft densely hairy.

DIATAGA, gen. n. 
(c.aray/) =arrangement.) 
Type: Diataga leptosceles Wism. (Tab. X. fig. 26.) 
Antennae it, & biciliate 2; basal joint enlarged, with strong pecten. Labial Palpi roughly clothed with 
projecting scales on the median joint; terminal joint laterally compressed, short, obtuse, smooth. 
Maxillary Palpi long, folded, coarsely scaled. Haustellum rather short. Ocelli absent. Head roughly 
clothed with long hair-scales. Z'horaw evenly clothed. Morewings narrow, elongate, the costa raised 
beyond the middle, thence again depressed to an evenly rounded apex, termen obliquely rounded: 
neuration 12 veins; 8-9 stalked; 10 approximate to9; 7 toapex; g-5 stalked; 3 from angle, 2 remote; 
1 basally furcate. Hindwings 1+, apex rounded, termen very obliquely, ¢gnvex, tornus scarcely indicated : 
neuration 8 veins, all separate, 5 nearer to 6 than to 4. Abdomen moderate. Legs: hind tibiae and 
tarsi long and slender, the tibiae roughly clothed above. sO 
A conspicuous genus, easily recognised.
