EUPITHECIA. By L. B. Prout. 275 



renowned specialist in this group, whoso worlc must be consulted for fuller information than the exigencies of 

 space allow us to give here, especially as regards the biology. Mention should also be made of two excellent 

 monographs dealing with the genus, Draudt's on the egg (Iris vol. 18, p. 280-320) and Petersen's on the 

 genitalia (Iris vol. 20, p. 203—314). 



E. tenuiata Hbn. (= macellata Fisck- Rossi., inlurbaria Frr., ? singularia Nokk) (12k). Forewing with (enuiata. 

 apex rather more rounded than in most Eupithecia. Brown-grey, in fresh specimens with a slight gi-eenish 

 tinge; costal area of forewing strongly marked, with large approximated spots; discal dot strong, the space 

 between it and the postmedian usually rather pale. — ab. niveipicta Bastelh. has the ground-colour white instead niveipicla. 

 of grey. — cinerae Gregs., from Scotland, is said to be larger, clearer ash-grey and with the lines weaker, dnerae. 

 but its constancy is questionable. — The egg is laid in cracks in bark of sallow and hibernates. The larva 

 feeds up very rapidly in the catkins. Imago from the end of May to July, common among the food-plant. 

 Distributed in Central and Northern Europe, reported also from Transcaucasia. 



E. inturbata Hbn. {= ? neglectata H.-Sch., subciliata Dbl.) (12k). Similar to tenuiata but with less inturhata. 

 rounded apex, strong yellow brown tinge in the ground-colour, smaller discal dot, more strongly marked hind- 

 wing, but especially by the long ciliation of the cf antenna. The egg hibernates; Dietze says "probably", but 



1 have myself bred it. The larva feeds on the flowers of maple. Imago in July, local in Central Europe. 



E. nigritaria Stgr. is said to resemble palustraria (13f) in size and colour but with the structure of intur- nigritaria. 

 hata. Black with fine, extremely indistinct, dull whitish lines, costal margin of forewing and base of hindwing 

 tinged with whitish, the former with a sharp white dot before the distal margin. Discal dots and interrupted 

 marginal line deeper black. Taurus. 



E. haworthiata Dbl. (= isogrammaria H.-Sch. nee Tr.) (12 k) is another small species with vathev haworthiaia. 

 rounded apex, most certainly recognizable by the conspicuous orange patch on the anterior part of the abdomen 

 dorsally. Wings darker grey than in teiiuiata, the discal dot wanting or quite indistinct. Larva in the flower- 

 buds of Clematis vitalba, easily detected by the round hole which it makes. The pupa hibernates and often 



2 or even 3 winters are passed in this state. The moth flies in June and July. Central and South Europe, 

 Asia Minor, the Caucasus, China and Amurland. 



E. homogrammata Dietze. Similar to haworthiata, mostly still smaller. Distinguished by the absence homogram- 

 of the orange dorsal patch; median band of hindwing beneath generally narrower and less angulated, some- *""'*• 

 times obsolescent. Amur and Ussuri in July. 



E. subtacincta Hmps. Darker than haworthiata, discal dots present, under surface much more sharply subtacincta. 

 marked, the paler bands being almost white; abdomen without distinct orange dorsal patch. Dharmsala. 



E. immundata Z. (== argillacearia H.-Sch.) (12 k) is a rather broad-winged, very weakly marked species imnmndata. 

 of a glossy, somewhat argillaceous grey colour; larger than the preceding group; discal dot wanting or scarcely 

 indicated; no pale subterminal line. — Larva in the berries of Actaea spicata. The winter — sometimes also ... ., 

 a second — passed in the pupa. — reikjavikaria Stgr., an almost unicolorous dark form from Iceland, is ,.j^ 

 referred here but nothing, I think, is as yet known regarding its biology. 



E. plumbeolata Haw. (12 k). Differs from haworthiata in its somewhat larger size, slightly straighter^ZMw?ieo/ato. 

 costal margin, lighter colour and absence of the orange patch on abdomen. Rather better marked than immun- 

 data, greyer, somewhat less glossy, besides being somewhat smaller, with less rounded costa. Larva in flowers 

 of Melampyrum. The pupa hibernates, often twice. Moth in June, distributed in Europe as far as to the Ural 

 and in Asia Minor and said to occur again in Amurland. 



E. lutosaria Bohaisch recalls plumbeolata (12 k) but is yellowish brown instead of grey, the lines white, lutosaria. 

 much more distinct, especially the double outer line of both wings; veins not chequered. Possibly a form of 

 spissilineata (13f). Achalzik, Caucasus. 



E, cuculliaria Rbl. (= undata Bohatsch, nee Frr.). Ground-colour paler than in plumbeolata, the scaling cucuUiaria. 

 thicker and coarser, thus not glossy, forewing somewhat more pointed, lines more dentate, fringes sharply 

 chequered, underside much more distinctly marked than in plumbeolata. The unchequered veins distinguish it 

 from the following. S. E. Europe and Konia, Asia Minor. 



E. spissilineata Metzner {= multilineata Mann) (13f). Somewhat variable in size and depth of colonv, s^pissilineata. 

 but easily known by the minute darker irroration in the ground-colour and especially by having the numerous 

 rather broad white lines almost entirely broken up into large vein-dots. Turkey, Greece, Asia Minor, etc.
