210 BRITISH LEPIDOPTERA. 



serves that he has in his collection 3 3 s and 4 ? s of genuine natural 

 esidae as well as two examples that have been artificially coloured. 

 Wiskott's seven examples came from Frankfort-on-Oder, Breslau 

 (1$), Dresden (2<^s, 1? from Kuhlmann), Leipzig (Miiller), 

 Austrian-Silesia (Troppau). According to Boisduval, it occurs in 

 Tuscany, Calabria, Sicily, and, as just stated, Romanoff records it 

 from Tiflis. Failla-Tedaldi records (Nat. Sic., vi., pp. 103, 161), that 

 he took two true ab. esulae on the Island of Lampedusa.

 Caput et thorax olivaceo-fusci, scapulis albo-marginatis. Alse anticse albo-griseae, 

 costa, maculis, macula lata prope basin, macula costali pone medium sita vittaque 

 postica olivaceo-fuscis. 3 , ? . Near D. tithymali, Bdv. This interesting new 

 species comes nearest to D. tithymali, and stands much further in all matters of 

 superficial resemblance from all other species of the euphorbiae-grou-p. 

 The larva is black and differs little from the dark form of the larva of euphorbiae. 

 It has a red dorsal line which becomes yellowish on the segmental incisions. 

 The yellow lateral line is broadened into a spot on the centre of each segment. 

 The two yellow spots on each side of each segment are margined with deep 

 black. On each side of the back are 4 rows of yellow dots. The caudal horn 

 and the head are yellow-red in colour, the former posteriorly blackish. Venter 

 black-grey. Legs exteriorly yellowish and black, interiorly red-brown (Christoph). 



Two larvae were found May 1 8th, 1873, on an unknown species 

 of Euphorbia, on the chalk formation, near Schahrud in Persia, 

 one of which produced a male, the pupal stage lasting about two weeks. 

 In the summer of 1893, Herz captured some larvae on the same plant, 

 two of which produced a $ and 2 , the former agreeing with the 

 one bred by Christoph. Bartel adds that it is only quite recently 

 that peplidis has been determined as a local race of the highly 

 variable H. eitphorbiae. Staudinger refers it (Cat., 3rd ed., p. 102) 

 to robertsi, Butl.

Hampson writes (Ind. Moths, i., p. 98): "The Himalayan form 

 lathyrus averages rather larger than the European H. eitphorbiae, the 

 latter averaging 60mm. — 80mm., the former 76mm. — 92mm." 

 Staudinger notes it as : " Multo major, pallidior, imago nonnunquam 

 a nicaea haud distinguenda." Kaye says that North Indian lathyrus 

 is possibly distinct although very near 11. euphorbiae. The head 

 is larger, and the front portion of the thorax projects farther beyond 

 the costa ; the wings are slightly longer and narrower ; the 

 fascia of the forewings is much speckled, and there is very little pink 

 in the hindwings ; the black marginal band on the hindwings 

 is much more extended, especially at the apex.
