EXAERETA; FENTONIA. By Dr. K. GRraBEEG. 291 



C. cyanea Leech (45 a). Head and thorax grey, abdomen grey-brown. Forewing dark reddish brown, cyanea. 

 with a brownish suffusion in cj, a more greenish suffusion in $, a curved postdiscal band indistinct. HLnd- 

 wing light grey-brown with darker margin. — Japan. 



C. pustulifera Oberth. (48g). Uniformly yellowish grey, abdomen with blackish lateral spots. On pmMifera. 

 the wings a numberof white, partly black-edged, tufts of scales, which indicate an indistinct prediscal line and a 

 postdiscal one, and are arranged in a row before the distal margin; at the apex of the cell a similar white 

 spot; fringes spotted with black. ■ — ■ Ta-tsien-lu. 



8. Genus: Exsereta Hbn. 



Antennae in cj with long pectinations to %, the rest bemg thin, filiform, like the entire antenna of $. 

 Palpi short, with long bristly hair. Proboscis moderately long. Eyes naked; ocelli present biit small. Fore- 

 wing very long and narrow, its costal margin quite straight to close to apex, distal margin first steep, then 

 strongly oblique, forming a very obtuse angle with the hind margin; vein 5 from the centre of the discocellulars, 

 6 close to upper cell-angle, from which the stalk of 7, 8, 9 is thrown off, 10 free from cell, forming an areole 

 with the stalk of 7, 8, 9. Hindwing likewise rather elongate, nearly semicircular, with the distal margin 

 somewhat undulate; vein 5 very feebly developed, 6 and 7 on a short stalk. Thorax and abdomen smoothly 

 hairy, legs with very long dense woolly hair; hind tibia with mid- and end-spurs. — • Larva long cylindrical, 

 with short minute hair, 14 legs, on abdominal segments 1 and 8 a small conical tubercle; head mcised at 

 vertex; anal legs modified into 2 long, divergent, rod-like processes which are widened in button-shape at the 

 tip. Pupa with 2 divergent anal brushes of hair; in the ground in a hard cell. — The only species is: 



E. ulmj Schiff. (= cassinia Esp.) (46 d). Head and thorax grey, abdomen pale grey-brown. Fore- ulmi. 

 wing grey, with darker spots, especially obvious being an oblique transverse spot at apex of cell commencing 

 at costal margin, a postdiscal row of white-edged black vein-dots and a similar row of dots between the veins 

 close to the margua. Hmdwing whitish, with brownish margin and brown veins. • — South Germany from 

 Southern Baden eastward. Northern Switzerland, Southern Tyrol, Lower Austria, Croatia, Dalmatia, Hungary, 

 Roumania and Southern Russia; southward to Corsica and Central Italy; also Armenia and Amurland. In 

 Central Europe only in some places ; the moth very rare as compared with the fairly abundant caterpillar. The 

 latter yellowish green to brownish or reddish, densely variegated with small light yellow spots which bear a 

 short hair each ; on the back a blackish longitudinal line composed of single bars extending across the segmen- 

 tal incisions. June and July. Pupa at the foot of the food-tree, black-brown, hibernating. Moth in April 

 and May. The larvae are best collected by beating, as they jump off when one knocks against the branch, 

 wriggle about on the ground and then hurry towards the trunk of the tree. They sometimes defoliate the trees, 

 the larvae coming down like rain when the trees are beaten, as in the case of Phalera bucephaki on young limes. 

 The larva feeds only on Elm, is full-fed in July and makes in the ground a roundish cell, from which the moth 

 emerges in the following April. As the caterpillar is very difficult to feed up in captivity, it is advisable to 

 take only full grown ones which show already by the dulness of the originally yellowish colour that they are 

 close before pupation (Aeno Wagnee). 



9. Genus: ITeutouia Butl. 



Antennae in (J either pectinate to the apex or the distal half only shortly dentate, in $ setiform. Palpi 

 upturned to the centre of frons, with a short pointed end-segment. Proboscis present. Eyes naked. Ab- 

 domen elongate, its apical third extending beyond hindwing. Hair on femora and tibiae very long, dense 

 and woolly; mid tibia with apical spurs, hind tibia with median and apical ones. Forewing elongate, with 

 produced apex, distal margin strongly oblique, almost the same in length as hind margin, hind angle very ob- 

 tuse; hindwing broad; vems 3 and 4 of forewing widely separate, 6, 7 and 8 stalked, 9 from 10, anastomosmg 

 with 8, forming a long areole. In hindwing 6 and 7 on a short or long stalk. • — The genus is essentially In- 

 dian, most of the species occurring in Anterior India. It is represented in the Palearctic Region by 4 East- 

 Asiatic species, of which 2 have only lately been described. 



F. OCypete Butl. (= laevis Bull.) (45 b). Body grey brown, variegated with white hairs on head and ocypete. 

 thorax, which are thereby rendered lighter in colour. Forewing grey-brown, in the typical form prommently 

 pale brown in the cell and in the basal portion of the hmdmarginal area, with black streaks and transverse 

 lines : along the median a black streak, a pair of parallel blackish lines before the middle and another pair beyond 

 the middle, the former rather diffuse, dentate, the latter well defined, strongly excurved below the cell; a sub- 

 marginal dentate line diffuse, and a dark marginal line distmct. Hindwing light grey-brown, darker at the 

 anal angle. Amurland, Corea and Japan; also at Simla (North India). — The Japanese specimens evidently
