32 EUXOA. By W. Warren. 



nagyagensis. margin fuscous ; occurs in all the countries of S. Europe, in Tunis, Sicily and W. Asia ; — in ab. nagyagensis 

 cycladum. Frr. the lines are distinct; — ab. cycladum Stgr., from the island of Naxos is smaller and rufous in colour. 



opipara. E. opipara Morr. (— islandica Pack: nee Stgr., labradoriensis Stgr., ? norwegica Stgr) (6i). Fore- 



wing pale grey; a blackish basal streak below cell; claviform stigma large, elongate, black, continued as a 

 black streak to postmedian line : upper stigmata grey, the cell and space beyond black ; slight fuscous 

 suffusion before the outer lines; hindwing brownish, with a dark cell-spot and outer line. A North 

 American species, of which a single specimen has occurred in Norway. 



nigrita. E. nigrita Graes. (6k). Forewing deep purple fuscous; the double lines filled in with reddish; 



stigmata all black-edged; the round orbicular and the reniform with reddish annuli, the cell between them 

 black; submarginal line with rows of black dentate marks on each side; hindwing fuscous brown. Raddefka, 

 Amurland; this species is distinguished by its short and broad wings. 



recussa. E. recussa Hbn. (= telifera Donz., florigera Ev., transylvanica H-Sch.) (6 k). Forewing purplish- 



grey, with redbrown suffusion; claviform stigma large, blackish; orbicular and reniform brown with grey 

 annuli; the cell black; no black streak below cell; hindwing luteous grey witli the termen dark. Generally 

 distributed in Europe, also found in Turkestan and Siberia. 



tritici. E. tritici L. (= pratincola Bkh., domestica Fab.) (6 k). Forewing dark brown, with costa and inner 



margin more or less irrorated with whitish: the median vein white; a black streak from base below cell; 



hindwing grey with fuscous terminal suffusion. Found abundantly throughout Europe and Asia except the 



aquilina. extreme east. — The chief aberrations are ab. aquilina Schiff. (= fictilis Hbn. fig. 479 (6k) larger and 



obelisca. dull brown, with luteous instead of white scaling, the costa generally paler; — ab. obelisca Stph. (and 



Brit, authors) resembles in a way the true obelisca Schiff. , but is smaller, with the antennae less 



eruta. developed; — in ab. eruta Hbn. (6k) the dark ground colour is overlaid with grey and the markings are 



siliginis. obscured; — while in ab. siliginis Guen. the ground colour itself is gre} r er; — ab. obscurior Stgr. is a 



obscurior. D ] ac ki sri form from Ussuri ; — ab. detorta Ev. from Mongolia and Siberia is reddish ochreous with pale 



• ' brown costa and distinct lines; — in ab. varia Alph., also from Central Asia, the costa, veins, and stigmata 

 varia. . J ' ... 



distincta. are conspicuously white; — ab. distincta Stgr. from S. Russia and Armenia may be specifically distinct, 



for besides being larger, with bright clear markings and white hindwing, the antennae are said to be 



thicker. — In addition to these more widely spread continental forms a considerable number have been 



proposed or quoted by Tutt, based on a comparison of British specimens and grouped according to 



ground colour and the presence or absence of a pale costal streak. Thus those having a pale slaty grey 



obsoleta. ground colour are ab. obsoleta Tutt, with the costa concolorous, and all markings obsolete, but sometimes 



the lower lobe of reniform dark. This form must be very near the following species sabuletorum Boisd. 



costa- and its ab. squalida Ev. — ab. costaobsoleta Tutt is like the last but with the costa paler and the 



obsoleta. ma rkings faint: — the next two have the ground colour clear slate or dove colour; — ab. coerulea Tutt, 



cOBrulsQ. ' 



costa- w ^ tn concolorous costa and ab. costacoerulea Tutt, with the costa pale, the markings in both cases more 



coerulea. or less distinct; the next two are greyish white; — ab. pallida Tutt, with costa concolorous and the 



pallida, markings fairly distinct; — and ab. sagittifera Sfph. with the costa pale, the markings all distinct, and 



sagittifera. -^ifh a dark mark between stigmata; — those with pale greyish fuscous coloration are ab. fusca Tutt with 



fusca. con cororous cos ta and well developed markings (very close to the ab. siliginis Guen.), and ab. costafusca 



Tuff, with costa and median nervure pale, the lines and wedge-shaped spots well-developed; two others 



sordida. have a dark greyish fuscous ground colour; — ab. sordida Haw. with costa concolorous and distinct 



pupillatus. markings; — and ab. pupillatus Haw. with the stigmata subocellate and the median area pale; two with 



odiracea. a yellowish ochreous ground are ab. ochracea Tutt with the costa concolorous and the lines clear, akin to 



virgata. detorta Ev.; and ab. virgata Tutt, which is pale reddish ochreous, with the space between inner and 



outer lines deep red-brown; the claviform stigma black, the upper two epiite pale; — with ground colour 



valligera. reddish brown there are ab. valligera Han: (= cuneigera Stph.) with costa concolorous, the markings and 



albilinea. wedge-shaped spots distinct, the cell dark; — and ab. albilinea Haw. (= lineolata Haw., aquilina Hbn. 



fig. 536) like the last, but with both costa and median vein white; — the following three are blackish 



venosa. brown; — ab. venosa Stph., well-marked, but with costa concolorous; — and ab. hortorum Stph., which 



nfswfwTa is m0re ash_colourecl ; — and ab. nigrofusca Esp. with the costa pale and the markings obscured; and 



nigra. l ast l v i we have two with ground colour black ; — ab. nigra Tutt with the markings distinct and the costa 



oceilina. concolorous ; — and ab. ocellina Stph. (= costanigra Tutt) with the costa pale or whitish. — Larva brownish 



ochreous; dorsal line pale; subdorsal lines dark with pale lower edge; lateral and spiracular lines greenish 



fuscous; on a variety of low plants: in Britain especially common on the sandhills of the coast. 



sabuletorum. E. sabuletorum Boisd. (= foeda Led., nigrina Stgr.) (7a). Forewing dull grey with a brown tinge; 



the dark markings as in tritici L. but never black brown and often altogether absent, except the dark lower 

 squalida. end of the reniform stigma; this unmarked form, = ab. squalida Ev. (7a), never occurs in tritici or its 

 various forms. S. Russia.
