H ORIS ME. By L. B. Prout. 



exohtata. H. exoletata H.-Schdff. (= exsoletaria H.-Schdff.) (13 m). Smaller than tersata, forewing less acute. 



Fuscous, postmediaii line forming a single cutward curve, subterminal bending strongly basewards behind the 2""* 

 median vein and forming a large white spot towards anal angle ; apex sharply divided. Antenna slightly 

 thicker than in tersata. Sicily. 



lucillata. H. lucillata Guen. Small and rather Euj)itJiecia-like, apex obtuse for this genus. Wings silky, light 



grey, the lines waved, parallel, not sharply expressed; postmedian geminate, slightly dentate, followed by another 

 line, then by a broad, rather darker distal area, subterminal obsolescent except at anal angle, where it forms 

 a large white spot; veins distally to the postmedian dotted with white and black. Underside weakly marked. 

 Altai end Changai Mountains. 



scotosiata. H. scotosiata Guen. Forewing with apex acutely produced, subfalcate; hindwing with inner margin 



short, distal margin strongly dentate, the tooth at 2"** medial shorter. Dark grey with the lines fme, rather 

 indistinct, subterminal forming rounded teeth, filled- in with blackish; discal dot small; a small black mark 

 between the 8'''* radial and P' median. Hindwing with 2 black subterminal lines, between them a brownish 

 tint, proximally some incomplete lines. Altai to Changai Mountuins; ? Amurland. 



plurilineala. H. pluHlineata Moore (= nigripunctata Warr., nigrovittata Warr.). Both wings rather long and 



narrow, forewing slightly, hindwing strongly crenulate. Rather variable, red-brown, the cf similarly marked to 

 the tersata group, the postmedian thickened and blackened behind ^"^ radial, the ? with blackish suffusions, 

 assimilating superficially to those of vitalbata, or almost wholly fuscous. N. India, widely distributed.

H. stratata Wileni. Closely related to plurilineata and with similar, if somewhat less extreme, sexual 

 dimorphism; perhaps a local form. Ground-colour paler, median area rather better defined, broader in middle, 

 narrowing strongly at inner margin. The cf rather recalls H. intestinafa Guen. Japan: Gokanosho, Higo, Sep- 

 tember — October; Oiwake. Recorded by Leech as vitalbata (!). 



H. aemulata Hbn. Similar to tersata testaceata, costal margin more arched distally, median band nar- 

 rower, widening a little at hindmargin, scarcely projecting distally about the 3''^ radial, antemedian line' 

 not blackened at hindmargin, apex not divided, veins distally to postmedian more sharply black-and-white 

 dotted. Hindwing not white costally. — ab. saurucki Schatverda is blackish grey, almost without markings. 

 — Larva similar to that of tersata, grey-green, the dark dorsal line broken into dashes on the middle segments, 

 these dashes placed in light lozenge-shaped patches. On Clematis. Moth in June— July, local and generally 

 rare, in the mountains from Switzerland to Bosnia. Staudinger adds "Urga (var. ?)". 



H. incurvaria Ersch. is said to be related to the following but seems, from the figure, to be rather 

 small and narrow-winged. Pale brownish fuscous, with numerous obscure lines, the postmedian lines angled 

 near the costa, discal dot black, subterminal fine, waved, whitish, terminal broken inlo dots; hindwing with 

 2 divided whitish bands and a very distinct subterminal. Irkutsk in June. 



H. calligraphata H.-Schdff. {= taeniolata Ev., ligaminata 7?c.) (25 i) may be known at once by its much 

 more whitish ground-colour. Discal dots minute or obsolescent; the principal lines of the forewing somewhat 

 accentuated at costal margin and on the veins. Larva stone-grey, less elongate than that of tersata, dorsal 

 line only distinct anteriorly and posteriorly, broken into an irregular pattern of spots on the middle segments. 

 On Thalictrum foetidum. Pupa shiny red-brown, similar to that of tersata; hibernating. Imago in June — 

 July, in sheltered localities a partial 2"'' brood. Local in the Southern Alps, Upper Styria, etc., and recorded 

 from the S. Ural and Transcaucasia. 



H. milvaria Chr. Rather smaller than calligraphata, rather more brownish, the lines of the median 

 area less broken up into vein-dots, the principal lines thickened at costa, the pale band beyond the median 

 area moderately distinct, the line which follows it showing a characteristic, rather oblique dark costal streak; 

 subterminal white line sometimes very conspicuous. Underside rather paler than in calligraphata, hindwing 

 with less lines developed. Abdominal crests very slight. Ordubad. I describe from a pair from the Sajan 

 Mountains, determined by Bang-Haas. Rather less yellow-brown than incurvaria Ersch, distal area less straight- 

 edged, subterminal line thicker, more deeply dentate; moreover incurvaria is said to show a dark discal mark. 



H. ? dentata B. Luc. Wings rather elongate, forewing rosy grey, subbasal line curved, antemedian 

 dentate, somewhat curved, discal dot distinct, postmedian dentate, distinct, somewhat curved basewards posteriorly, 

 according to the figure accompanied proximally by a narrow grey shade, some less strong waved lines between 

 the postmedian and the distal margin, apparently most distinct anteriorly. Hindwing concolorous, with a discal 

 dot and 3 or 4 lines beyond it. Forewing iDeneath infascated, especially between discal dot and base. Tarf, Algeria, 

 in May. The figure, apparently not very good, shows a small, slendery-built species not suggestive at a Horisme.
