EUPITHECIA. By L. B. Prout. 



demetata. E. demetata Chr. (= ? draudti Dietze) (13f). This and the following are little-known and doubtful forms. 



demetata is more brownish than typical venosata, approaching the form ochracae in colour; the 4 principal 

 iineS; according to the figure, are placed nearly as in venosata, but with the antemedian straighter and rather 

 nearer to the subbasal, the postmedian also less irregular in its course; the accompanying fine line is very 

 weak and the white bands scarcely indicated; veins not blackened Kopet-dagh, near Askhabad. 



stigmaticata. E. stigmaticata Chr. (13 f) which was discovered together with demetata, is very similar but of lighter 



reddish-yellow colour, with the median line wanting, except as a costal mark, and with a very strong, linear 

 cell-mark. Transcaspia and Hi district. 



hilariata. 



silenicolala . 



gelinaria. 



carpophi- 

 tata. 



E. hilariata Dietze differs appreciably from venosata in the genitaUa and in the antenna of the cT, 

 which has longer ciliation — exceeding somewhat the diameter of the shaft. Paler than schiefereri, with a 

 more earth-coloured tone, the approximation or fusion of the black lines in the median area, which only occurs 

 as an aberration in schiefereri, is here normal; fringes chequered; discal spot black, very large. Underside 

 light, with scattered dark scales, the markmgs of the upper surface indicated. Juldus Mountains, Hi district. 



E. silenicolata Mah. (12 m) is best distinguished from the 3 preceding by its longer, sharper palpus, 

 which is more than twice as long as the diameter of the eye; antennal ciliation in the & about as long as 

 the diameter of the shaft. Ground-colour uniform smoky grey with violet reflections, the markings similar to 

 those of venosata but the spaces between the parallel lines not lighter, the median line accompanied distally 

 by one or two finer parallel lines, while in venosata it is simple. Larva on Silene nemoralis; in Corsica on 

 S. paradoxa. Flight-time May. Vallais, Central Italy, Styria and Corsica, probably also Bosnia and Bulgaria. 



E. gelinaria D. Luc. is perhaps a form of the following, it seems scarcely to differ except in having 

 the anterior (distally directed) curve of the postmedian deeper and a slight angle in the same line on the 

 2"'' median, thus somewhat approaching silenicolata. Nefta, S. Tunis. 



E. carpophilata Sigr. (13f) differs from silenicolata especially in the form of the postmedian line, which 

 is curved somewhat in an S-shape, not dentate, and entirely lacks the sharp angle inwards on the 2°'' median 

 vein as well as the black streaks on the veins. In Staudinger's latest Catalogue it is suggested that it may 

 be a variety of the following species. Aragon and the Ussuri district. 



alliaria. E, alliaria Stgr. [\2q). Brownish grey with extremely fine black lines of varying distinctness, commonly 



with the subbasal, antemedian (twice dentate outwards) and postmedian (strongly curved in anterior part, without 

 deep indentation posteriorly) distinct, the rest faint; cell-dot distinct; pale subtenninal line present, thickened 

 noiaia. near anal angle. — notata Dietze has the discal dot larger and blacker, the antemedian and postmedian lines 

 very strong; ground-colour perhaps less greyish brown. Spain and S. France. — Larva on Allium, end of 

 August to beginning of October, spun up among the flower-heads. The moths flies at the end of June and 

 in July. The name-typical form inhabits Lower Austria, Hungary and Asia Minor. 



terrenatn. 



ponderata. 



iribunaria. 



egenarm. 



E. terrenata Dietze is said to be related to the venosata and alliaria groups, but the genitalia are 

 comparable with those of virgaureata. Bather long-winged, uniform earth-grey, discal spot of forewing large, 

 black, antemedian and median lines double, the latter touching the cell-spot; several postmedian lines, the 

 proximal one strongest. Has been confused with iribunaria, but differs in colour, etc. Variable. Near 

 Askhabad. 



E. ponderata Dietze. Smaller than terrenata, less elongate, cell-spot much smaller, the double median 

 line not sharp, a distinct subterminal present, fringes distinctly chequered, palpus somewhat stronger. Narrower 

 and less brown than alliaria; stronger whitish abdominal crests distinguish it from both. Ordubad. 



E. tribunaria H.-Sch. (13 g). Bluish grey with 3 double white bands, the middle one the strongest, 

 passing just distally to the cell, here rather strongly excurved, and only separated from the postmedian by a 

 line; the subbasal well removed from the middle one; no discal spot; distal area broadly grey, entirely, or 

 almost entirely, without a subterminal line. Caucasus to N. Persia. 



E. egenaria H.-Sch. (= undosata Dietze) (IBg). Perhaps related to tribunaria but of a much less bluish 

 grey (slightly tinged with brownish) and with distinct discal spots. The median area of the forewing is bounded 

 by pairs of dark lines, the first of the distal pair particularly strong, somewhat thickened at the costal margin; 

 two faint, sinuous median lines run from the inner margin to the discal spot; the pale subterminal line is 

 distinctly indicated. The life history is not certainly known; it has been bred from larvae collected with those 

 of tripunctaria and virgaureata, probably from an Umbellifer, but has also been reported as from the blossom 

 of Ume. Very local, S. France to S. E. Bussia, also Livonia.
