EUPITHECIA. By L. B. Prout, 283 



mixed with ochreous, especially in the region of the veins and at the costal end of an inconspicuous double 

 pale median band, which runs across the end of the cell to the middle of the hindmargin; other lines also 

 inconspicuous, in places whitish, the subterminal a little more distinct, fine, whitish, dentate; cell-spot black, 

 moderately elongate, terminal strokes thick, black; principal veins black, dotted with white where the lines 

 cross them. Hindwing with apex prominent, though rounded; cell-spot and terminal marks as on forewing; 

 costal one-third and cell rather light, the rest darker, lines chiefly indicated as white dots on the veins. 

 Madeira: Raba^al; only a ? known. 



E. helveticaria Bsd. (12 g). Very variable, sometimes very similar to the equally (or still more) variable helveiicaria. 

 satyrata, best distinguished by the presence of a dark dorsal belt near the base of the abdomen. In general 

 also with more elongate forewing, more brownish tone, larger cell-spot (oftener repeated, though much smaller 

 and weaker, on the hindwing), somewhat stronger lines bounding the median area, the postmedian less angularly 

 bent than in the strongest-marked form of satyrata {curzoni), more indistinct (sometimes obsolete) subterminal 

 line, rather more strongly spotted fringes, etc. I am doubtful whether the insect which passes in Britain as 

 helveticaria (= f. anglicata) is the same as that of continental authors. Crewe was convinced that we have 

 two species in Britain, but unfortunately I do not possess the one which he called arceuthata. As name-type 

 DiETZE accepts a rather narrow-winged form from high altitudes in Valais, with the ground-colour about as 

 chocolate with milk. Its larva is said to feed exclusively on Juniperus communis var. nana, but Anderegg 

 recorded it from J. sabina — a further ground for uncertainty! The moth flies in June and July. In captivity 

 partially double-brooded. — anglicata Mill., from Scotland, is another brownish form, rather smaller and anglicata. 

 broader, more reddish brown. The larva seems, according to Crewe's description, to be similar, but less 

 blackish, the head purple, sometimes almost black, the anal extremity of dorsal line purplish, subdorsal and 

 lateral perhaps less interrupted. Full-fed in September. — intricata Zett. (= septentrionalis Dietze). Mostly intricata. 

 smaller and more slightly built, often lighter in colour (more ash-grey), the discal dot smaller. From the most 

 northerly localities (Finland, etc.). Seems to me a form of the following. — arceuthata Frr. (12 g). On an arceuthata. 

 average rather broader-winged than helveticaria, the colour more grey, or violet-grey (less brown), the alternately 

 dark and light spotted veins (which are characteristic of this species and satyrata) showing up more distinctly. 

 Larva bright green, the pale subdorsal and broad yellowish white lateral lines uninterrupted. Grows very 

 slowly, full-fed in late October or November. Widely distributed in Central Europe. — robusta Dietze is a robusta. 

 powerfully built form which perhaps does not belong to this species. Markings similar but at the same time 

 somewhat recalling suhoxydata. Ground-colour with a strong admixture of brown, sprinkled with black and 

 silver-grey. Radde, Amurland. 



E. scopariata Rhr. (= scop aria Bsd., tenebrosaria H.-Sch.) (12 h). Longer-winged than the preceding, scopariata. 

 with narrow hindwing. Antenna in cf with rather longer ciliation (at least V2 as long as diameter of shaft). 

 Median vein commonly conspicuously black except where crossed by the pale line's. Discal dot small, not 

 elongate, often wanting. Abdomen with P' segment, mediodorsal line and the incisions pale, otherwise more 

 or less darkened dorsally. Described from Corsica; I accept the name as referring to the brownish form which 

 occurs in Spain and Italy. — multiflorata Mill, from Cannes, Nice, Istria, etc., is more purplish, more sharply „jM?i!j/Zorato. 

 marked with white and fuscous. — guinardiaria Bsd. (=: graslinaria Stgr) denotes the larger, paler, more guinardia- 

 reddish-brown or ochreous-tinged forms which occur in Western to South-western France. — matertera Dietze ria. 

 is also large, but more sepia-coloured, weakly marked. Castile. — farinosa Dietze is a somewhat differently- "^rwTosa."' 

 marked aberration, or possibly distinct species, nearest guinardiaria, equally large but pale violet-grey, with a 

 mealy appearance. Described from a single ?, Cuenca. — orientata Stgr., from Transcaucasia and perhaps orientata. 

 Transcaspia, may possibly be also a separate species. Said to be grey, almost entirely without brownish, 

 weakly marked and without the whitish lines. — Larva on Erica arborea and E. scoparia; feeds throughout 

 the winter, fullgrown February — March. Moth in April — May. Mabille reports a second brood and Dr. Chapman 

 found it flying in abundance at the beginning of July at Canales, N. Spain. 



E. rusicadaria Dietze. Broader-winged and essentially darker and less sharply marked than scopariata, rusicadaria. 

 presenting a very distinctive, dusky appearance; subterminal line of forewing sometimes forming a light spot 

 near the hind angle, discal dot small but distinct; fringes beneath mostly more distinctly chequered than in 

 scopariata. The genitalia also show some difference. Philippeville, Algeria, at street lamps in May. The larva 

 accepted Erica in captivity but was not bred through. 



E. veratraria H.-Sch. (12g). Very similar to satyrata but considerably larger, of a slightly different veratraria. 

 tone of colour (inclining to violet-grey), the discal dot stronger than is usual in satyrata, more often repeated 

 on the hindwing, the principal lines generally extending into black spots at the costal margin of the forewing, 

 the whitish subterminal spot near the posterior angle somewhat stronger. — eynensata Grasl. (= magnata eynemata. 

 Mill.) is in general larger, paler and more weakly marked. Recorded from the Pyrenees and Transsylvania.
