162 DIPLURA; NADASIA. By Dr. K. Grunberg. 



densely covered with long ,yello\v hair from the base to the light spot terminating the outer band. Hindwing 

 lighter brown. Underside reddish browii, both wings with gre_\ash yellow transverse band, only reaching to 

 vein 4 in the forewing. At the basal side of the transverse band both wings densely covered with grey scales. 

 $ like the (J, only shghtly lighter and more thinly scaled. Amurland, Japan. On the wing in July. Eggs red- 

 dish yellow. Larva cyhndrical, thinner at both ends, without long lateral hairs, head small, dull black, body 

 clothed with yellow hair, dark grey with a row of velvety black dorsal spots cUvided on segments i to 10 and 

 bouiaded laterally by a light sickle-shaped mark. Underside reddish yellow. Gregariously in a wliitish grey 

 web, only feeds at night, hibernates and then feeds up until June or July. Cocoon very hard, parchment- 

 like. Sometimes two to four pupae in one cocoon, the pupa hibernating again. In Southern Amurland (Vladi- 

 vostock), however, the insect only hibernates once. 



9. Genus: Diplura Ramb. 



A well-characterised genus confined to the western Mediterranean area and only containing two verj^ 

 closely allied species. Antennae of (J with long pectinations, in the $ onl}' serrate. Palpi small, shghtly pen- 

 dant, indistinctly jointed. Eyes hairy. Hair of tlie body of ^ long, of the ? shorter; abdomen of ^ with a 

 divided bifid long anal tuft. Wings entire; forewing triangular, with sharp apex; costal margin only shghtly 

 curved in the outer half, distal and inner margins moderately curved; liind angle broadly rounded. Costal 

 margin of liindwing strongly excurved at the base, distal margin rather strongly curved. Forewing with 12 

 veins, 2 to 4 at almost equal distances from the liind margin of the cell, 5 from the hind angle of the cell, 

 distinctly separate from 4, 6 and 7 from the upper angle of the cell, 8 close before it, 9 and 10 on a short 

 stalks ; 2 to 8 into the margin, 9 into the apex. In the hindwing 3 to 5 close together from the hind part of 

 the apex of the cell, or 4 and 5 on a short stalk, 7 beyond the centre or close to the cell-apex, united close 

 beyond the base by a strong transverse vein with vein 8, whicii latter is strongly curved towards the costal mar- 

 gin already at the base, so that a very large basal cell is formed, which is almost larger than the true cell. A 

 moderately large accessory vein emanates from the base of vein 8. Cell closed in both wings; cross-vein of 

 forewing irregularly curved, and in the liindwing angulate before the centre. Femora and tibiae with long 

 but rather sparse hair, tarsi smoothly scaled, fore tibiae not armed, middle and liind tibiae with two short end- 

 spurs. The species are uniformly red-brown or greyish brown, with sharp white discal spot and outer wliite 

 dentate line on the forewing. — Larva long, cylincU'ical, with irregular hair, long at the sides, and producing 

 strong inflammation. Only two warts of different size at each side of the first segment; segments 2 to 5 dor- 

 sally with two transverse short and very dense tufts of hair beyond the middle, on segments 2 and 3 another 

 pair of such tufts at the anterior edge; segments 6 to 12 without these tufts and in the middle only sparsely 

 hairy. Yellowish bristles on all segments at the anterior and posterior margins; segments 6 to 10 in addition 

 with two or three felty spots covered with white hair. Pupa short and stumpy, naked, reddish brown, in an 

 elliptical parchment-Uke cocoon. 



lotl. D. loti O. (26 d). ^ dark reddish broM-n, forewing with sharply defined white discal spot, and white, 



slightly wavy, postdiscal band, which is broader at the inner mai'gin. Underside hke upper, band more indistinct. 

 9 slightly larger, dark greyish brown, discal spot sharply defined, band indistinct : underside almost or entire- 

 ly without markings. West and Southern France, Spain. Flies in May and June. Larva grejash brown 

 with white lateral hairs, the bristles on the anterior and posterior edges yellow. Head brown, hairy. Accord- 

 ing to Mendes from the end of August to May, and according to RotiAST from ^lay to August, on Cistus 

 salviaefolius. As regards pupa cf. description of genus. 



algeriensis. D. algerlensis Baker (= brumiea Oberth.) (26 d). Also regarded as a form of loti: similar to the preced- 



ing, l)and of the forewing of the ^ strongly and sharply dentate. $ dark brown, with ill-defined discal spot, 

 without band. End of July and August, not rare on stony slopes; according to other statements specimens 

 also occur in April (from hibernating pupae ?). 



10. Genus: Xadsisia Walk. 



Very closely allied to Diplura, containing two small species onl}' known from Egj'pt. Antemiae of (^ 

 with long pectinations, of ? with shorter ones, which are however distinct to the tip. Apex of forewing more 

 rounded than in Diplura, inner margin straight, costal margin of hindwing considerably longer than the inner 

 margin. Vein 6 and 7 as well as 9 and 10 on a long stalk in the forewing, stalk almost as long as the free 

 ends of the veins ; 9 into the margin, 10 into the apex. Two accessory veins at the base of the hindwing. First 

 tarsal segment with a few long hairs on the outer side. Colour uniformly dirty greyish brown; forewing with 

 minute white discal spot and various light and dark wavj^ lines, or almost without markings. — Larva and 

 pupa of N. obsoleta have been described by Kltjg. 

 %mdala. N. undata A7h<7 (26 d). Body grepsh brown with a reddish tinge, forewing of the ^ of the same colour, 



discal area darker, bounded proximally and cUstally by a whitish dentate hue. A blackish, finely dentate, band 

 before the margin. Fringes with hght spots. Hindwing Ughter grey, with ill-defined dark submarginal band
