OCNEROGYIA, ALBARRACINA, TOPOMESOIDES. By Di-. E. Strand. 133 



0. ( amabilis Chr. (21 d). The ^, from Askhabad, has light oUve-brown forewing slightly suffused amabilis. 

 with grey, with three blackish browTi transverse bands: one before the centre narrow, distinctly curved distad, 

 another nearly in the centre just as narrow but less curved, and a marginal band two or three times as broad. 

 Fringes like the forewing, indistinctly chequered with dark. Hindwing orange-yellow, with fringes of the 

 same colour, and deep black band slightly narrowed posteriorly, at the distal and costal margins. Beneath both 

 wings orange-yellow, forewing slightly lighter than hindwing, black at the costal margin as far as beyond the ' 

 centre, and further distally with a black spot and a similar marginal band and spot in the middle of the cell ; 

 the underside of tlie hindwing similar to npperside. 



20. Genus: <^cucrog;^'ia Stgr. 



Unknown, to me ; the systematic position not recognisable with certainty from the inadequate descrip- 

 tion; it is even questionable whether Ocnerogr^/ia really belongs to this group (Inareolatae). It is compared 

 with Orgyia, but is said to be most closely related to Ocneriri. The antennae have a very slender shaft, and 

 much longer, slenderer and more widely separated pectinations than the species of Orgyia, and are moreover 

 longer than in the latter, being slightly more than half the length of the costal margin of the forewing. Tho- 

 rax and vertex appear to be clothed with long thin hair, also the frons. Palpi extremely small, lying on the 

 hairs of the forecoxae. — Only one species: 



0. atnanda Stgr. from Mardin in Mesopotamia. Forewing uniformly dark brown-grey, hindwing ochreous amanda. 

 browii with brownish grey fringes. Thorax and vertex light browTi-grey, frons and abdomen ochreous 

 brown, discocellular spot indistinct. 31 mm. 



21. Genus: Albarraeina Stgr. 



This genus is also only known to me from Staudinger's description. Antenna of (^ long, bipectinate 

 and pointed, nearly as in Ocneria terebinthi, that of the $ with short pectinations, shorter than in terebinthi. 

 Thorax clothed \vith long hairy scales. Tegulae much raised. Thorax laterally clothed with long hair. 

 The hindtibia with two pairs of fairly long spurs. End of abdomen of $ with long hairs in wreath-shape. 

 Forewing more elongate than in most species of Bombyx, outer margin very convex, inner margin only slightly 

 shorter than costal one. Venation ,, rather different from that of the species of Bombyx (especially the 

 median cells are not nearly so short)". Only two species. 



A, korbi Stgr. (21 d), from Albarracin in Eastern Central Spain, is light ashy grey ; fore wdng with blackish korbi. 

 irrorations, veins darker, distally a transverse row of 6 — 7 black spots and near the margin a row of black trans- 

 verse bars. Hindwing whitish dusted with grey ((J), or grey with white fringes (?). Underside of forewing uni- 

 formly black-grey, \vith sharp white costal margin and whitish spots before the outer margin, the fringes appearing 

 almost chequered with black wliite. (^ 30, 2 33 mm. — From Jaffa in S3Tia var. syriaci Stand f. (22h) has been syriaca. 

 described, which is of a lighter colour throughout: fringes more uniformly grey and all the markings of 

 the insect more obsolescent, hindwing and abdomen of the rj almost uniformly white; moreover, the fore- 

 wing is narrower %vith the margin less curved and with a dark stripe extending into the apex. ^ 29 — 30, 

 ? 32 — 33 mm. — Baxg-Haas has described without naming it a 2-form of korbi from Tunis (in Iris XIX, 

 p. 130), which is distinguished by the strong black macular wavy line being absent or nearly so. 35 mm. 

 I suggest calling this form var. deundulata Strand. deundulata. 



A. baui Stand/., from Palestine (according to Staudinger's Catalogue) or Syria (according to Stand- baui. 

 fuss) is slightly smaller than korbi (cJ 26 — 28, $ 28 — 31 mm), slenderer, antenna of ^ with shorter pectinations, 

 forewing broader than in syriaca and hghter above, the hindwing however darker, being grey, but with 

 snow-white and indistinctly chequered fringes. Forewing chalky white, veins with black scales, there 

 being also black shading in the cell and around it; in cells 2 and 3 deep black wedge-shaped spots, in cells 

 4 and 5 these are absent (in contradistinction to syriaca); costal margin with deep black oblique streak before 

 the apex. Underside of forewing dark grey, partly lighter at the margin, that of the hindwing of (J white, 

 with obsolescent discocellular spot, black shading at the dorsal margin and an irregular row of spots paxallel 

 with the outer margin; the hindwing of $ beneath light grey. 



22. Genus: Topomesoides gen. nov. 



Most closely allied to Topomesa Walk., but vein 8 and 9 both terminate at the costal margin, 10 

 originating closer to the cell than 7, the discocellular of the hindwing is more oblique (the cell anteriorly 

 considerably shorter than posteriorly) and veins 6 and 7 of the hindwing are separated at the base, 7 really 

 originatine from the anterior margin of the cell. — Type: T. (,,^raa") jonasi Btlr. (19 h, 3).
