42 RHYACIA. By W. Warren. 



cuprina. R. cuprina Stgr. (12c) Forewing dark leaden grey, flushed with red ; all the lines much obscured ; the 



stigmata interruptedly edged with white and black scales; hindwing white, with the veins and outer margin 

 brownish. Found in the Thian-Shan Mts. in W. Turkestan. 



Section V: Antennae of <? ciliated. 



subsequa. R. subsequa Sehiff. (9c). Forewing rufous grey; orbicular and reniform stigmata with pale out- 



lines, the former oblique, the latter always darker; lines obscure; a small black brown blotch on costa 

 before submarginal line: hindwing yellow, with large blackish lunular cell-mark and submarginal band; 

 fringe yellow. Occurs throughout Europe, including North Britain, and in W. Asia, but always rarer than 



consequa. orboua Hufn. — In the ab. consequa Hbn. (= sarmata Ramb.) (9 c) the forewing is longer, greyish fuscous, 

 with all the markings blackish and much plainer; the Hnes pale grey, the outer conspicuously paler at 

 costa; the stigmata dark brown; a southern form, occurring in Spain, S. Russia and Afghanistan; and very 

 probably specifically distinct. - Larva ochreous fuscous, the lines yellower; the dorsal and spiracular 

 broad with black edges; a subdorsal row of oblique blackish bars; on various low plants. 



orbona. R. orbona Hufn. (= subsequa Esp. nee Sehiff., pronuba-minor Fill., comes Hbn.) (9 d). Forewing 



reddish brown with reniform stigma brown, and hindwing orange with dark border and discal lunule ; 



distinguished from subsequa Sehiff. by the absence of the black costal mark before submarginal line; commoner 



than subsequa Sehiff., but with the same range of distribution, occurring besides in Algeria and the Canaries; — 



adsequa. the form adseqtia Tr. (9c, d) differs in being pale grey; — grisea Tutt is dark grey; — and ochrea Tutt 



grisea. p a i e ochreous; — in rufescens Tutt (= rufa Tutt) (9d) the forewing is wholly reddish; — in prosequa Tr. 



? ' '" the markings all come out very prominent; — while the ab. curtisii Newm. (= consequa Curt, nee Hbn. 



fit t€$C6flS . 



prosequa. an< ^ °f "which nigreseens Tutt seems merely a dark form) (9d) has the forewing suffused with brownish 

 curtisii. fuscous ; the lines, edges of stigmata and base of fringe yellow; the costa dull red above and below; hind- 

 wing with basal yellow area clouded with blackish, and the fringe bright yellow; the costa on underside 

 nigra, broadly black; — ab. nigra Tutt, with both wings wholly suffused with blackish, is a melanic form from 

 bergensis. Scotland only; — in ab. bergensis Sp.-Schn. from Norway the forewing is partially suffused with fuscous; — 

 virgata. in ab. virgata Tutt the median shade is exaggerated to form a dark band; — ab. attenuata nam. nov. 

 attenuata. e— su bsequa Haw. nee Sehiff.) has the black border of hindwing narrow and submarginal; — ab. conjuncta 

 7 ' nom. nor. {= subsequa Curt, nee Sehiff., var. C. Guen.) is burnt brown in colour, with the stigmata conjoined, 

 fumida. and the veins pale; — lastly, a very distinct ab. fumida nov. (9e) from Cyprus has a dark fuscous forewing 

 tinged with grey: the lines and edges of stigmata grey; the fringe wholly fuscous; hindwing wholly smoky 

 orange; underside with no red tinge; the forewing dull yellow-grey, the hindwing greyish yellow. — Larva 

 ochreous : dorsal and subdorsal lines faint , the latter connected by a bar on segment 1 1 ; spiracular line 

 pale, with a row of triangular spots above it; feeds on all low plants. 



R. pronuba L. (9e). Forewing pale grey (typical) or ochreous, or reddish brown, or dark brown, 



pronuba. often with dai'k and light mottlings , and with a pale costal streak ; stigmata also variable ; reniform with 



lower lobe generally dark ; a double black spot on costa before submarginal line ; hindwing orange with a 



submarginal black band; shoulders and tegulae frequently not concolorous with forewings; — a common 



innuba. species throughout Europe, in West and Central Asia, and occurring in Egypt; — in the ab. innuba Tr. 



hoegei. (9e) the whole forewing and body are dark brown without markings; — ab. hoegei H.-Sch. is small, and 



the hindwing shows a black discal spot: all the specimens of this form were bred, so that it may have 



connuba. been the result of hybridisation; — ab. connuba Hbn. (9e) is a dwarf form, with the markings indistinct, 



and the hindwing paler yellow. — Larva dirty ochreous, with the lines pale and a series of- oblique black 



streaks on each side; on all low plants. Besides the above-mentioned forms Tutt has proposed names 



for several mere colour variations, such as ochrea, rufa, brunnea, coeru/escens , together with subvarietal 



names, based on the presence or absence of a pale costal streak and dark interspaces in the cell of forewing. 



atlantica. R. atlantica Warr. (9f). Forewing dull reddish brown; the markings indistinct; orbicular stigma 



round, concolorous : reniform filled up with fuscous ; a small black streak on costa before submarginal line ; 

 hindwing dull yellow, suffused throughout with smoky grey; a dull blackish submarginal band; veins and 

 extreme margin dull rufous; fringe yellowish. Azores. 



stentzi. R. stentzi Led. (9f). Forewing grey-brown with a vinous tint and purplish fuscous suffusion 



towards base; costal streak, as far as outer line, broadly cream-colour; the cell, a triangular blotch on 

 costa before apex and another at base black; stigmata grey, with pale outline; claviform bullet-shaped; 

 orbicular semicircular, dependent from costal streak; hindwing brownish fuscous; tegulae velvety-brown 

 with creamy base. Altai Mts., in Siberia; Fergana, W. Turkestan; Hi, E. Turkestan; Amdo, Tibet. A 

 smaller species than triangularis Moore; the outer line finely black; the submarginal preceded by a row of 

 black spots. 



dulcis. R. dulcis Alph. Like stentzi Led., but smaller, with narrower wings; forewing with the same 



markings, and in addition the median vein yellowish white; the outer line faint and the costal bar before
