 ger, lighter grey, markings indistinct and diffuse. Egypt, early stages unknown. 



N. obsoleta Klug (26 d). Uniformly brownish grej^, forewing with indistinct dark discal and submar- obsoleia. 

 ginal bands. Egvi^t. — Egg pale yellowish, deposited on slender twigs of Acacia. Larva blue-grey, underside 

 yellow with black spots, sides with fine sporadical black dusting and long grey hairs. Back with yellow longi- 

 tudinal band dotted with black, and irregular black lateral band bounded by a black stripe of spots on the 

 outer side. First and last segments blackish blue, 2, 10 and 11 with long black dorsal tufts of hair, 3 to 6 with 

 short brown brush-like hairs, 7 to 9 each with two black warts. Pupa dark brown, stumpy, in a regular elliptical 

 greyish white cocoon, attached to slender t\\dgs at the top of Acacia-trees. 



11. Genus: diileiia Walk. 



Of this genus, wliich is essentially Oriental and Ethiopian, only three species are Palearctic, occurring 

 in the East-Mediterranean district. Antennae with long pectinations, wliich are only slightly shorter in the 

 9 than in the (J. Palpi short with rather long bristles, end-segment small, knob-like. Eyes densely hairy; frons 

 smooth. Body very hairy, abdomen of (J pointed, with longer anal hairs and lateral tufts on the middle seg- 

 ments. Forewing and the rather long fringes entire. Forewing broad with rounded apex, costal margin slightly 

 curved only in the outer half, distal margin also moderately curved, inner margin almost straight. Costal margin 

 of liindwing slightly excurved at the base, then straight, distal margin strongly curved. Veins 6 and 7 of the 

 forewing on a short stalk from the upper angle of the cell, 8 close before it, free, 9 and 10 stalked, stalk 

 shorter than the free ends of the veins, 2 to 9 into the distal margin; in the hindwing 4 and 5 on a short stalk, 

 8 free from the base, soon after its origin united with 7 for a short distance, forming a small basal cell with it; 

 two strong accessory veins ; 1 b to 7 into the distal margin, 8 into the costal margin. Cell closed in both wings; 

 cross-vein of forewing very slender, angulate laear the lower angle of cell and then strongly inclining to- 

 wards the apex of the wing. Femora, tibiae and first segment of fore tarsi with long hair, tarsi smoothly scaled, 

 with long segments, middle and hind tibiae with short end-sjiurs. The species are uniformly grey or greyish 

 brown, with white discal spot and dark oblique transverse bands in the forewing. — Larva cylindrical, with 

 soft hair, especially laterally, without lateral warts, the dorsal warts also feebly developed but bearing a few 

 longer bristles. Segments 2 and 3 with four dorsal short dense tufts of hair each, 11 rather strongly raised 

 with a few longer hairs, 5 to 10 with three ventrolateral transverse stripes of smooth silky hair. Pupa brown, 

 naked, with stumpy, rounded, non-armed end, tliin skinned, in a strong parchment-Hke white cocoon. 



C. obliquata Khig (26 e). Greyish wliite, forewing suffused with brownish, with an ill-defined obliquala. 

 brownish transverse band from the apex to the middle of the imier margin. Egyjjt. 



C. sordida Ersch. (26 e). Antennae brownish yellow, body grey, wings lighter or darker greyish brown; sordida. 

 forewing with wliite discal spot and two parallel ill-defined blackish brown transverse bands, the inner one 

 running from the apex to the middle of inner margin. Underside almost without markings, and without discal 

 spot. Central Asia. Very variable. — Larva bluish grey; segment 1 with two black spots, 2 and 3 almost black 

 with yellow hind margin ; the other segments bearing yellow dorsal and lateral lines with reddish yellow mark- 

 ings, and blue dots between them. On Alliagi camelorum, first brood in April, the second already in June. 

 As the time of development is so short, perhaps a third brood also occurs. Pupates on the food-plant or on 

 some undergrowth near by. 



C. proxima Stgr. (26 e). Most closely allied to sordida, antennae dark brown, ground-colour of ^ dark proxima. 

 brownish grey, of $ lighter. Discal spot of forewing sometimes indistinct, the imier dark transverse hne in 

 immediate proximity to the discal spot, the outer one strongly dentate. Mesopotamia. 



12. Genus: Cosmotrielie Hbn. 



Medium-sized species, from bright yellow to reddish brown in colour, in the forewing with an usually 

 large white double discal spot and dark oblique band rumiing from the apex of the wing to the inner margin. 

 Antennae of (^ with very long pectinations, in the $ with short ones. Palpi strongl}' porrect, with long cyhn- 

 drical end-segment. Eyes shghtly hairy, the hairs sometimes (laeta) very sparse. Frons shghtly convex, 

 smooth. Body densely hairy. Forewing elongate, but rather broad, costal margin curved only in the outer 

 half, apex sharply marked, rectangular, outer margin moderately curved, inner also curved or almost straight, 

 liindwing broadly rounded with strongly curved distal margin. In both wings the distal margin is more or 

 less distinctly wavy. Forewing with 12 veins, vein 2 near the base, 5 from the lower angle of the cell, 6 and 7 

 as well as 9 and 10 on a short stalk, 8 free from the upper angle of the cell; 2 to 8 into the margin, 9 into 

 the apex ; in the liindwing 4 and 5 from a point or on a short stalk {laeta), 8 strongly curved at the base and 

 united with 7 by a long oblique transverse vein beyond the middle of the cell, a large broad basal cell being 

 formed; from tliis basal cell four or five accessory veins radiate, the outer longer one running parallel with
