160 GEACILIPALPUS; STYGIOSTOLA. By W. Warren. 



molybdea. A. molybdea Chr. (39 c). Like micans but paler: the reniform stigma faintly expressed; hindwing 



much paler. Recorded only from Sarepta, S. Russia, and Asia Minor. Perhaps not truly distinct. 



alpherakii. A. alpherakii Stgr. (38 e). Eorewing pale ashgrey from base to submarginal line, before which the 



grey is darkened, and sometimes becomes fuscous, with the veins pale between outer and submarginal 

 lines; inner and outer lines very indistinct; the former obliquely waved outwards, the latter excurved 

 above, then vertical; costa marked with dark spots where the lines rise; orbicular stigma a flattened 

 oval, whitish: reniform pale, defined by darker; the cell sometimes dark; terminal area beyond submarginal 

 line whitish grey; marginal lunules black and regular; hindwing luteous whitish, becoming rufous fuscous 

 along termen; the fringe white. Hi, E. Turkestan. 



cancellaia. A. cancellata spec. not. (— alpherakii Hmps. ab. 1., nee Stgr.) (38 e). Decidedly larger than 



alpherakii, greyish brown in coloration, becoming dark brown before the white submarginal line, with the 

 traversing veins white; the cell also dark brown; the orbicular a small pale ring with grey centre; the 

 reniform a pale lunule; lines as in alpherakii,, but both more distinct; terminal area and fringe pale 

 ochreous grey; hindwing fuscous, with a coppery tinge basewards; the fringe pale grey. Tedschen oasis, 

 Merv, W . Turkestan. Apparently an intermediate form between the preceding species alpherakii Stgr. and 

 the next species sergei Stgr. 



sergei. A. sergei Stgr. (39 c). Larger than the last species, but with the same coloration and markings; 



the stigmata blackish with fine white annuli. W. and E. Turkestan. 



4. Genus: Gracilipalpus Call. * 



Distinguished from Amptiipxjra Tr. by the presence of crests on the prothorax and metathorax; 

 the second segment of palpi is broadly fringed with scales in front, while the third is long and porrect 

 instead of being erect; the antennae of the $ are ciliated. Type Gracilipalpus ephialtes Hbn. 



manica **' turcomanica Clvr. (4'2a). Eorewing grey suffused with blackish brown, slightly reddish- tinged; 



median area darker except just beyond the reniform, the postmedian area darker in costal half; inner and 

 outer lines dark, double, filled in with grey; orbicular stigma hardly visible, rounded; reniform dark with 

 pale annulus; subterminal line whitish, preceded by a grey shade; hindwing fuscous, with a pale oblique 

 line just beyond middle. W. Turkestan. 



ephialtes. G. ephialtes Hbn. (= nubilaris Grasl.) (4'2 a). Eorewing glossy grey brown dusted with darker; 



lines dark conversely pale-edged, the inner nearly vertical, the outer excurved above; the reniform stigma 

 a diffuse dark patch; orbicular absent; submarginal line pale, defined by the preceding dark shade; hind- 

 wing rufous fuscous. Spain, Italy, Sicily, Morocco. 



5. Genus: Stygiostola Hmps. 



Agrees with Gracilipulpus in having the prothorax and metathorax crested; but the antennae of 

 the <J are heavily bipectinated to apex, those of the $ having tufts of scales on each segment; palpi with 

 second segment thickly fringed with hair, the terminal shortly porrected; pectus and legs woolly; ? smaller, 

 with narrower wings, than J. Larva hatched in autumn hybernates, feeding up in spring; pupation sub- 

 terranean. Type Stygiostola umbratica Goeze. 



umbratica. S. umbratica Goeze (= tenebrosa Hbn.) (38 f). Eorewing dull fuscous brown, sometimes greyer- 



tinged, at others more fulvous along inner margin and across wing; the lines dark, but usually indistinct, 

 though indicated on costa by pale spots; inner line waved, oblique outwards; outer line more vertical, 

 lunu ate-dentate; submarginal line paler, preceded by a darker shade; median shade broad, diffuse, gener- 

 ally well-developed : passing between the upper stigmata, which are rarely clear; the orbicular small and 

 round, the reniform with whitish scales on outer edge: hindwing dull fuscous; the greyer Examples are ab. 



lerr^lnea P haeus Haw - d ( =: obsoletissima Haw. $) (38 f) ; — ferruginea Stph. (? Esp.) (38 f) is the form with 

 obscura. part al fulvous suffusion: - - ab. obscura Tutt (38 f) has the ground colour unicolorous blackish brown 

 with the markings more obscured, occurring in Scotland and other localities. Larva thick, dark red- 

 brown; dorsal and subdorsal lines yellowish: between them a series of oblique dark streaks; spiracular line 

 grey; spiracles black; head dark brown; feeding on Fragaria and Geum, and other low plants. Of general 

 distribution throughout Europe, (except the extreme South, Spain, Greece), also occurring in Armenia. 



ripleyl. S.'? ripleyi Ho//. Forewing grey, the basal half paler than the terminal; inner and outer lines 



double, blackish, filled in with greyish white; an irregular black spot at base edged with white; orbicular
