58 PERISSANDRIA; SPINIPALPA; XESTIA. By W. Warren. 



26. Genus: Pei'issandi'ia gen. nor. 



fully developed, as in Rhyacia; ? only one-fourth as large as cf, with hindwings aborted, and 

 slight slender abdomen: superficially like, a dull Tineid rather than a Noctuid; the contrast between the 

 sexes is absurd. 



Type /'. argillacea Alph. 



argillacea. P. argillacea Alpli. (= decolor Stgr., agama Stgr.) (13h). cf: forewing veiy variable; either uni- 



form greyish ochreous without markings of any kind; or suffused with pinkish brown, with the upper 

 lineata. stigmata only, generally grey with pale rings, rarely blackish; — in one example, ab. iineata ah. nor. (13 h), 

 the inner and outer lines are double, waved, and marked by dark scales; — or suffused with dull reddish, 



albistigma. the lines all marked with blackish scales and the stigmata white, ab. albistigma ab. nor. (13 h); the costa 

 mottled dark and light ; in all but the palest there is a dark dash at base of cell ; hindwing pale to dark 

 grey; 2 dingy grey or yellowish grey, without markings. Kuku-Nor, Tibet. 



poliodiroa. P. poliochroa Hamps. Forewing of cf stone grey with a greenish tinge; lines black; the stigmata 



with a thick black edge; fringe whitish, with two dark lines through it; hindwing pale grey; fringe white; 

 ? paler, with the markings minute; the stigmata replaced by two dark dots. Gyantse, Tibet. 



27. Genus: Spinipalpa Alph. 



Distinguished, according to Alpheeakt, by the terminal segment of palpi ending in two horny 

 spines; frons smooth; all the tibiae strongly spined; eyes naked, but ciliated; thorax and legs rough-haired; 

 antennae bipectinate. 



Type S. maculata Alph. 



maculate S. maculata Alph. (= aletes Hamps.). Forewing pale brownish grey; costa at base and the outer 



veins paler, somewhat grey; no stigmata or cross lines; the wing is marked instead by longitudinal black 

 streaks, at base, in the cell, and between the veins of the disc and outer margin: hindwing uniform 

 brownish grey; thorax like wings; tegulae marked with a white bar. Described from a single cf from 

 Amdo, Tibet; -- also occurs in Sikkim, whence comes the type of aletes Hamps. who compares the insect 

 in appearance to a Leucania. 



28. Genus: Xestia Hbn. 



Frons smooth ; all the tibiae spined , and the foretibiae also fringed on outer side with long hair ; 

 pectus rough-haired; forewing with apex somewhat produced; the two lines approximating on inner margin. 



Type A', ochreago Hbn. 



Section I: Antennae of cf moderately bipectinated to near apex. 



antiqua. X. antiqua Stgr. (15 h). Forewing grey, with slight brown markings; some brown scales near base, a 



suffusion along vein 1, a small spot at lower end of cell, and patch on costa before subterminal line also 

 brown: hindwing dark fuscous. Occurs in W. Turkestan. 



koeppeni. X. koeppeni Alph. (15 h). Forewing pale grey-brown, whiter towards base ; the two lines both distinct, 



marked on costa by dark spots; stigmata obscure, the orbicular oblique, the reniform small; hindwing pale 

 grey with dark cellspot. W. Turkestan. 



octireago. X. ochreago Hbn. (== ochrojois Hbn., nubecula Tv.) (13 i). Forewing ochraceous tinged with red; 



lines fine and indistinct; upper stigmata large, brown-edged, the reniform with lower lobe dark; a diffuse 

 dark shade before submarginal line; hindwing rufous ochreous, paler just before terminal line. A local 

 species found in France, Switzerland, and Italy; also recorded from Armenia. 



Section II: Antennae of ? with pedicellate fascicles of cilia. 



miniago. X. miniago Frr. (13i). Forewing ochreous brown with a pink flush; lines fine, whitish, not dentate; 



variago. stigmata with slight pale outlines; hindwing white. — The form variago Stgr. has fuscous irroration on 



forewing, head, and thorax. — An eastern species, found in S. Russia and Armenia; Siberia and Turkestan, 



xestiodes. X, xestiodes Hamps. (13 i). Forewing rufous ochreous, darker beyond inner and before submarginal 



line; inner and outer lines rufous, finely waved; stigmata outlined with rufous, the upper two paler; hind- 

 wing fuscous ochreous. Goorais Valley, Kashmir. 



fuscisignata. X. tuscisignata Hamps. (13i). Forewing rufous ochreous; lines whitish with darker edges; stigmata 



with pale outlines; the orbicular large, the reniform dark in both lobes; a narrow shade before submarginal 

 line: hindwing ochreous yellow. — Described by Hajipson from a single ¥ from the Goorais Valley, Kashmir,.
