and darker, the larva feeding on leaves of ash (England and the Middle Rhine) or also on blackthorn, white- 

 thorn, rose, etc. In warm localities it occurs as the summer generation of innotata, August-October. — 

 suspectata Dietze is a still smaller summer-brood form from the Middle Rhine, bred from more delicately 

 built, blackthorn-feeding larvae. - tamarisciata Frr. (121), single-brooded at Tegernsee (Bavaria), a summer 

 form of innotata in other southern localities, is the product of a variegated green, white-mixed larva which 

 feeds on Myricaria germanica and Tamarix gallica. The moth is generally larger than fraxinata, more leaden- 

 grey than innotata. — grisescens Petersen is a bluish-grey, scarcely brown-mixed form from Esthonia and 

 probably East Prussia, Uralsk, etc. — perturbatrix Dietze is a pale sand-coloured, weakly marked form from 

 the desert region of Korla, Central Asia. — uliata Stgr., from the Uliassutai district, was founded on two 

 worn, strongly blackened ??. — corroborata Dietze, from Hi, Issyk-kul, etc., has the transverse markings strongly 

 blackish. — omniparens Dietze is a strikingly large grey form from many localities in Central Asia (Zerafshan, 

 Issyk-kul, etc.) approaching f. parallelaria. — paupera Dietze has the groimd-colour blackish, the markings 

 almost wanting. Hi and Ferghana, transitional to the following. — praesignata Bohatsch, perhaps a separate 

 species, is said to be larger and at the same time more delicately built and more weakly scaled than tamarisciata, 

 palpus small and short. Fringes apparently longer and softer than in innotata. Trans-AJai. — parallelaria 

 Bohatsch. Mostly larger and lighter than innotata, the cf approaching tmedonata. Bohatsch described it as a 

 large, light, more distinctly marked race of that species. Distributed in Central Asia and especially Mongolia. 



unedonala. E. unedonata Mab. (13 i). Near innotata, the forewing generally more acute, more cinereous, the lines 



straighter, less broken up into spots, the subtei-mlnal as a rule less distinct, discal spot more slender. As 



autumnalis. with innotata, the name-type represents the large spring-brood form. — autumnalis Dietze, the second-brood 

 form, is essentially smaller and corresponds approximately to innotata f. fraxinata. — Lai'va on the blossom 

 of Arbutus unedo in October— December, also in Tunis on Rhus dioca; food-plant of the summer generation 

 unknown. Moth in March and again about October, often taken at light. Distributed in the Mediterranean 

 hybrida. countries. — hybrida Dietze is the result of crossing this species with innotata, which is apparently not 

 dilficult to accomplish if unedonata is prevented by artificial cooling from emerging too early. Both crossings 

 were obtained, so that another name is really required; the larvae and moths generally inclined to follow 

 those of the ? parent.

E. costisignata Dietze (= ? famelica Dietze) was originally regarded as a form of unedonata, but the 

 genitalia prove it to be a distinct species. Nearly always distinguishable by the black costal spots, though 

 these vary much in size. The palpus appears shorter than in innotata. The name-typical form is light ash- 

 grey. Korla and Yarkand. — relaxata Dietze is a large form from Schahkuh, Persia, sometimes (but not always) 

 without the costal thickening of the lines. — infumata Dietze, from Naryn, Turkestan, is a dark, smoky form. 

 — privata Dietze (? spec, div.) is more weakly marked, with oblique double lines from the middle of the 

 forewing to the hindmargin, there not essentially thickened. Transcaspia. — vicariata Dietze dill'ers from the 

 preceding in that the proximal of the two middle lines gradually thickens towards the hiiulmargin, suggesting 

 a transition between unedonata and phoeniceata. Zerafshan, 250U m, in July. — decipiens [Petersen) Dietze is 

 similar to vicariata, but shows a dark distal boundary to the median area of the forewing and a distinct discal 

 dot on the hindwing. Schahkuh. — adjunctata Dietze. More yellowish than vicariata. Border of both wings 

 interruptedly black. Korla. Is likely to prove a separate species. — mitigata Dietze pale yellowish grey, quite 

 weakly marked, the lines more rounded near costa. As the wings appear somewhat broader and the palpus 

 somewhat shorter this may also be a separate species. Lob-nor. 



novata. E. novata Dietze. Position doubtful; in habitus recalling innotata. The peculiar elongate forewing, less 



elongate hindwing and short body are said to be characteristic. Iron-grey, tinged with violet-bluish, scheme 

 of markmgs as in gemellata, the coarse, rough scaling more as in santolinata. Zeitun, Taurus. 



virgaureala. 



E. virgaureata Dbld. (= offirmata Grentzb., pimpinellata Gueti. nee Hbn.) (12 f). Superficially similar 



to castigata but with & antennal ciliation long, costal margin somewhat more rounded, colour generally some- 

 aestiva. what more yellowish grey, etc. Very variable. — aestiva Dietze, the summer generation, is considerably smaller. 

 altenaria. — altenaria tityr. is a very weakly marked, sometimes almost unicoiorous form from Finmark, Lapland and 

 Transbaikal. — The June larvae feed on whitethorn, blackthorn, etc., the autumn brood on the flowers of 

 various Compositae, etc., preferring Solidago and Senecio. North and Central Europe and across Siberia 

 to Japan. 



detritata. E. detritata Stgr. is said to have thinly scaled, dirty grey wings and black discal dot, resembling alte- 



naria, but narrower-winged almost as innotata. Ussuri district. 



lentiscata. . E. lentiscata Mab. (13i), Perhaps somewhat related to virgaureata. Brownish grey, the dark markings 



indistinct, strongest costally, marked with spots on the veins; 3 parallel lines between basal and median area
