PTYCHOPODA. By L. B. Prout. 101 



loped; head very small; colour variable, brownish or greenish; dorsal line blackish, double, accompanied by a 

 triangular dorsal pattern; lateral ridge pale; setae thickened at their extremities. Pupa little elongate, green- 

 ish brown, head darker, wings prominent, abdomen more reddish, spiracles dark brown. — ab. lecerfiata Horn- lecerfiata. 

 herg (= brunneofasciata Andreas) (3f) has a slightly more reddish tone, the lines (especially the median) less 

 strongly expressed, the dark shading in the distal area, on the other hand, very much intensified 

 and showing again (though a little less strongly) distally to the subterminal line, which appears a little 

 narrowed. The distal margin of the hindwing seems to project rather less strongly, and the postmedian" 

 line similarly to be somewhat less excurved in the middle, and altogether the aspect is that of a separate 

 species. Andreas and Homberg have proved, however, by breeding experiments, that this is not the case, 

 and one is inclined to regard it as a Mendelian form, although a certain number of examples are more or less 

 intermediate in aspect. Andreas obtained from eggs of the type form a brood consisting entirely of ab. lecer- 

 fiata, while a pairing of this brood resulted in 65% of lecerfiata 14% of ordinary suhsaturata 12% with the band 

 pale, 9% with the band developed but very narrow. If the latter be regarded as a modification of lecerfiata 

 and the former of suhsaturata we get 74% : 26%, or very closely the Mendelian ratio, the aberration being, 

 as is usual, the Mendelian "dominant", suhsaturata occurs at one locality in S. Prance (Cette) and is distri- 

 buted in Spain and Algeria. The form lecerfiata is only yet known from Algeria. There are, at least in 

 captivity, three broods in the summer. 



Pt. spissilimbaria Mah., briefly diagnosed on a single specimen from Algeria, without more exact spissilim- 

 locality, is a problematical species, and it is doubtful whether it can be certainly identified from the published ^^ria. 

 information. As Staudinger has altered the description of the colour, I suppose he has examined Mabille's 

 type, and perhaps the fact that he places it next after suhsaturata indicates that he noticed a resemblance 

 to that species; if so, it might even be an extreme development of the lecerfiata form, which was at that time 

 unknown. In any case it is likely to represent an aberration or variety; apart from Staudinger's indication 

 I should have thought it possible that it represented extarsaria eriopodata, earlier described by Mabille as 

 atromarginata. spissilimbaria is described as whitish rufous (by Staudinger as dirty ochraceous) with the base 

 a little darkened, an ill-developed angled median line and the distal area of both wings very broadly violaceous 

 blackish, the proximal edge of this border bisinuate. Under surface whitish in basal half, blackish in distal. 



Pt. foedata Btlr. (= salutaria Chr.) (4 c). Coppery brown with almost straight median and strongly foedata. 

 sinuate postmedian dark lines, the forewing in addition with a slightly curved antemedian line. Cell-spots 

 blackish, that of the forewing nearly always placed on the median line, hence sometimes not very apparent; 

 that of the hindwing on or a little distally to the median line. The area between the postmedian line and the 

 distal margin almost always contains some dark shading, but this varies greatly in extent; sometimes it is 

 confined on the forewing to a small blotch at the anal angle, more frequently it suffuses the entire posterior 

 half and not rarely the whole of the distal area; the latter, according to the description, is Christoph's form; 

 on the hindwing the dark shading is oftener weak, or confined to small patches near the angles. Distal margin 

 with not very conspicuous dark dots. Underside rather paler, without the first line and the distal shading. (J 

 antennal joints projecting, with rather long ciliation; hindtibia rather thick, tarsus as long as tibia. Bt7T- 

 ler's type and another from Tokio are rather dark, but there is in general very little variation in the ground- 

 colour. Widely distributed in Amurland, Korea, China and Japan and reaching Formosa. June to August. 



Pt. salubraria Stgr. is described as similar to foedata, and indeed its author thinks it is even possible salubraria. 

 that it might represent the summer brood of that species; but as he states that the (^ antennal ciliation 

 is "short, much shorter than in salutaria" I do not consider that the union is possible. Light clay-yellow 

 with black discal dots, the forewing with 3, the hindwing with 2 reddish transverse lines, both wings with 

 somewhat darker, violet-grey distal border. The ground-colour is sparsely irrorated with blackish. The lines, 

 as in the previous species, variable in their form and position; the discal dot is placed shortly before the 

 median line of the forewing, beyond it on the hindwing. The third (postmedian) line is darker posteriorly 

 and the violet-grey distal area is here the most pronounced on the forewing ; on the hindwing it is well deve- 

 loped throughout. The underside is glossy light-grey, the first line wanting, the median line of the hindwing 

 faint. The legs and palpus seem to agree with those of foedata. Differs strikingly from that species in the 

 much lighter, yellowish ground-colour and the reddish (not dark) lines. Sutschan district, Ussuri. 



Pt. proximaria ieecA, (7c) described as a CAft/socrasperfa, is distinct in aspect from all the Northern proicwnaHa. 

 and Western Palearctic species, slightly recalling some species of the Neotropical genus Hamalia. Yellowish 

 light brown, the costal margin of the forewing darker purplish brown, antemedian lines obsolete, postmedian 

 sinuous, marked by blackish dots on the veins; distal margin narrowly dark purplish brown, fringe spotted 

 with the same opposite the veins, both wings with black discal dot present, that of the forewing with some
