118 ORGYIA. By Dr. E. Strand. 



versely and pointed ]K)stiTiorly, wluk' llie apical one is elongate-rectangular; between the two a dark i)rown 

 transverse s])ot wJiich is dentate on its outer side and sometimes continues slightly narrower to the liindinar- 

 gin; at the inner angle a small sharply defined white transverse spot. $ entirely wingless, with whitish woolly hair; 

 it never leaves the cocoon, in which it also lays the eggs. The species varies strongly, the chief form occurring 

 anceps. in .Soutli France and on the Iberian Peninsula. — In Algeria andMorocco occurs var. anceps Oberih. (22 b), which 

 is usually larger and has the forewing sooty chestnut-colour, almost without markings and with only an indica- 

 tion of the transverse line, while the white spot at the hind angle is usually even larger and more rounded than 



transicns. in the main form ; hindwing like the forewing without markings. — transiens 8tgr. occurs in South. Mauretania 

 as a transition to the following; it is slightly smaller than anceps and brighter chestnut with grey costal mar- 

 ginal spots. — Specimens from Calabria in coll. Turati have the forewing already distinctly chequered with 

 sicula. reddish brown and grey, and therefore form a transition between e/rMsca and s«c«/f/.. — sicula >S<(/r. (22 b), from 

 Sicily, has the forewing greyish chestmit, almost without darker lines, with ob.solescent grey costal spot, some- 

 times with a grey median transverse hand and before it a transverse line of the same colour, spot at inner angle 

 ilrtixca. small and yellowish (always?); hindwing usually light chestnut. — etrusca Verity (22b). from Tuscany, 

 is distingm'shcd from sicula by the costal spot of the forewing and the very distinct and sharply defined exti'abasal 

 cornira. line and the similar median band. — Corsica Bdv. (19 a), from Corsica and North Afi'ica, questionably also 

 from Sicily, is as dark as or still darker them the principal form and without distinct grey costal marginal spots 

 or other distinct markings, with the exception of the ^\■hite spot at the inner angle, the reniform mark edged with 

 ^\■hite and tMo transverse lines bounding the median area, the proximal one of which has a white iimer edge; 

 raiiiiiiii-i. smaller than the main form. — I incline to the opinion that ramburi Mab. is not a mere synonym of Corsica, 

 as is stated in Staudinger's Catalogue and as Spuler suppo.ses. ramburi seems to be slightly larger, still darker, 

 without the reniform mark and Avithout sharply marked transverse lines, therefore also without a well-defined 



oncnlalis. ,nedian area, the spot at the inner angle more rounded. — It is probably closely allied to orientalis Stgr., from 

 prisrti. the Taurus, Syria and Palestine, which is said to be blackish brown. — prisca Stgr. (22 c), from Ferghana and Mon- 

 golia, is probably also closely allied to trigotephras, St.utdikger and Rebel considering it a questionable , .Spe- 

 cies darvviniana" of the same. The o is smaller than antiqua (23 to 26 mm), witl). more whiti.sh markings on the 

 forewing and light brown liindwing ; there is usually an indistinct narrow reniform spot at the cross-veins edged 

 with, grey and above it at the costal margin an often very large grey distinct spot; there is grey dusting at the 

 inner margin forming a luilf-band and before the whole of the outer margin. $ without a trace of wings, 

 with whitish grey hairs. — The eggs of trigotephras are quite white; deposited by the fluffy hairy white $ in 

 th.e cocoon, which the $ does not leave and in which it dies. Dr. Seitz found the larva of the form Corsica 

 in Algeria not rarely on Quercus ilex; it is violet grey with yellow longitudinal stripe and red-lead coloured 

 dots, ivory white silky dorsal tufts and black pencils on segments 1 and 11, without tlie lateral pencils found 

 in antiqua below the tufts. From May to Jiily. The q,^ fly by day; their flight is more quiet than that of 

 antiqua; when pursued the moth at once flies up into the air; from June to August, possibly again in the 

 later autumn. 



criccw. 0. ericae Germ. (19 b). cJ: Forewing rusty brown, lighter distally, with irregular transverse lines 



and whitish irregular spot at the inner angle, and often with a whitish smear in the middle of the costal 

 niitirjitoidc.s: nuirgiii (ab. antiquoides Hbn.); the latter form also appears to differ in the rather smaller size, darker ground- 

 colour and indistinc^t or obsolete spot at the inner angle, but I cannot ascertain with certainty if the latter 

 characters appear regularly together with the whitish smear at the costal margin. Occurs in North-West Germa- 

 ink-rincdia. ny, Belgium, Denmark, Finland, Armenia, Changai Mts. in Mongolia. — In Central Hungary occin-s var. inter- 

 media Friv., which is larger and darker with more distinct markings, and forms a transition to var. Corsica 

 of the preceding species, from which it is however distinguished by the much larger size and rather lighter 



Iccchi. colour. — leechi Kirby (= prisca Leech nee Stgr.), described from Chang -Yang, is, although perhaps a separate 

 species, closely allied to ericae. The (^ has chestnut forewing bearing two transverse lines, the inner one being 

 almost straight, the outer one first curved towards the apex and then directed oblicpiely towards the inner 

 margin. Discal area of wings suffused with a darker shade costally, at the middle of the costa a few white scales 

 and at the apex a white smear. Hindwing dark chocolate brown. Underside light brown suffused with a dark- 

 er tint. 30 mm. Central and West China. — Egg of ericae white. Larva ochreous, variegated with red, 

 with black markings, light yellow dorsal tufts and black pencils behind the head and on segment 11. May 

 until July, on heather and other low-growing plants. Pupa yellowish grey, with yellowish hair and black mark- 

 ings, in a yellowish grey cocoon. The moth on moors, in July and August, locally common. 



rupvslris. 0. rupestris Ranih. (19 b). J: Forewing brown, with indistinct darker spots and three narrow greyish 



white transver.se bands, the proximal one of which is straight and almost linear, the distal one broader ante- 

 riorly and not reaching the margin posteriorly ; between the two outer ones a greyish white transverse spot at 

 the costal margin ; hindwing lighter brown. $ whitish grey, with tiny wing-renmants. — Larva blackish, with 

 two reddish yellow irregular dorsal lines, blackish dorsal tufts and pencils, as well as lighter coloured warts; 

 until the end of Mtvy on Dianthus and Lotus. Pujia black with reddish brown dorsal s^jots; cocoon under
