384 PSEUDOGNOPHOS; GNOPHOS. By L. B. Prout. 



colchidaria. its shape, its small black discal dots, straighter postmedian line, etc. • — colchidaria Led. (22 a) is the darkest 

 cocandaria. form, the upper surface being mostly dark fuscous. Hi and Issyk-kul and probably Transcaucasia. — cocan- 



daria Ersch. (= degeneraria Stgr.) is paler, the upperside fuscous grey or yellowish grey, underside dirty 

 objectaria. whitish with broad fuscous border. Transcaspia and Mesopotamia. — objectaria Stgr. (= cocandaria CAr. 



nee Ersch.) has the upperside greyish, variegated with ochreous or reddish, the distal area darker, the underside 



white with the black border very broad. The prevailing form in the Zerafshan district, but also recorded from 



the same localities as the preceding. 



macuUfem. G. macuiifera Stgr., also from Zerafshan, is considered to be perhaps a Darwinian form of colchidaria. 



It is whitish grey with the bands formed of blackish grey spots. The underside sometimes lacks the dark 

 borders. Samarkand. 



riibraria. G. rubraria Stgr. is distinguished by the brown-red coloration of the forewing. Variable, the markmgs 



not sharp except the costal spots, light subterminal line and in some examples black marginal dots. According 

 mbruhraria. to the figure, broader-winged than the preceding. S. E. Taurus, Antiocha and Palestine. — subrubraria 

 Stgr., from Ferghana, is a more greyish form, thus intermediate towards colchidaria. 



136. Genus : Pseudognophos Stgr. 



Face not protuberant, scarcely rough-scaled. Palpus short, moderately stout. Tongue developed. 

 Antenna in ^ simple. Forewmg with distal margm smooth, oblique; 1st — 2nd subcostal coincident; fovea 

 wanting (?). Hindwing with distal margin weakly undulate. 



Probably a superfluous genus, differmg little, if at all, from some of the smoothest-margined species 

 of Boarmia; but I have seen only the ^. 



mardinata. Ps. mardinata Stgr. {22 a). A not very striking species, the dii'ty- white (in places slightly yellowish) 



ground-colour very densely trrorated with fuscous, the usual lines of Boarmia present, but only moderately 

 strong; antemedian indented near costa, then curved outwards, median shade irregular, strongest m the angle 

 of the median vem and its 2nd branch, then bending basewards to touch the antemedian on the fold, postmedian 

 line forming a series of lunules, the deepest placed on the folds, a dark distal spot between the radials. 

 Underside less strongly irrorated, weakly marked. Mesopotamia: Mardin. 



137. Genus: Ouophos Tr. 



Face usually prominent, with appressed scales. Palpus short or moderate, shortly rough-scaled. Antenna 

 in (J simple, or bipectinate with short or moderate branches. Fovea wanting or (in a few doubtfully placed 

 species) slight. Forewing usually broad, with distal margin less oblique than in Boarmia, sometimes crenulate; 

 all veins present, the anastomoses of the subcostals very variable. Hindwing with distal margin often crenulate 

 or dentate; 2nd radial wanting. A variable genus in structiu'e and one which has never yet been quite satis- 

 factorily defined. Often more easily recognized by markings than structure, the ringed discal spots and the 

 general grey coloration being characteristic though not universal features. A few $$ are apterous or semi- 

 apterous. — ■ Egg usually with more or less strong longitudinal (interpolar) ridges and slighter transverse ones, 

 forming a reticulated pattern. Larva rather stout and rugose, generally with small humps or raised points on 

 the 8th abdominal segment. On low plants. A few more slender, smoother, Rhamnus-f ceding species are 

 perhaps not truly congeneric. The moths are mainly mountain species and are to be found sittmg on rocks 

 with wings outspread. Chiefly Palearctic, with stragglers in N. India, Africa and America. 



A. Distal margins crenulate. Antenna in (J bipectinate (Ctenognophos subgen. nov.). 



eolaria. Q. eolaria Gtien. {= obtectaria Walk., paganata Feld., tenebrosaria Moore) (22 b). The type of my 



.subgenus Ctenognophos . A large species, variable on the upperside but with a distinctive and fairly constant 

 underside — ■ glossy greyish white with postmedian row of dots and broad fuscous marginal band. Above varied 

 brown and fuscous, sometimes with partial or complete whitish band in the neighbourhood of the dentate black 

 fuscobrun-^ postmedian Ime. — ab. fuscobrunnea Warr. is ,,duU rufous brown without any pale dusting." — ab. paerlita 

 paerlita. Btlr. is more uniform greyish, the lines broken into dots. — Distributed throughout the Himalayas, and rea- 

 ching W. China. 



incolaria. G. iticolaria Leech (22 b) seems sufficiently distinct from all the forms of eolaria, forewing rather less 



acute at apex, the brown coloration givmg place to dark blue-grey, the median area white with slight brown 

 clouding distally to the cell. Hindwing beneath with the dark border narrowed. Only known from Kwei-chow. 



lichenea. G. Hchenea Ob. (22 b). Forewing still more rounded, rather less broad. May be known by the remarkable 



mixture of olive, pinkish, black and white scales, the white sometimes prominent as a patch towards the end
