96 PTYOHOPODA. By L. B. pRotJT. 



between the radials and -with, only a very slight sinuosity towards the anal angle. Mouse-grey, not strongly 

 brown-tinged, antemedian Ime angled, median and postmedian parallel with distal margin, dark proximal 

 shading to subterminal and the subterminal itself weak or wanting. Hind wing without antemedian line. Both 

 wings with dark cell-dot. Under surface paler grey, similarly marked. Egg ellipsoid, slightly flattened at 

 the sides, surface presenting 10 — 12 rather broad channels formed by elliptical depressions; white, becoming 

 somewhat rosy. Larva short, thick, attenuated anteriorly from the 3. abdominal and carinated laterally, 

 segment-incisions not deep; skin transversely folded, rugose, granulated; greyish clay-colour, tinged with 

 greenish, some lines and striation brown; dorsal fine, hardly distinct, subdorsal broken, forming vague 

 lozenges and curved marks, lateral line formed of oblique striae; the lateral carina pale; ventral double, festoon- 

 ed; tubercles small, not very distinct, setae very short, claviform; head flattened in. front. Feeds on low 

 plants, accepting either fresh or withered leaves. Undergoes 3 moults. Pupa smooth, shining, reddish brown; 

 wing-veins prominent; cremaster broad at its base, suddenly narrowing, ending in a pointed beak. A suc- 

 cession of broods throughout the summer. Algeria. OberthiIr, on account of the shape, referred this species 

 to Euacidalia, which has a double areole. 



volloni. Pt. volloni Luc. u. Joan. (= plumbearia Bang-Haas nee Leech) is very similar to the preceding spe- 



cies, but may be distinguished at once by the course of the postmedian line, which is angularly broken near the 

 costal margin of the forewing, forming an acute angle inwards, then oblique outwards to another acute angle 

 on the first radial; it is punctuated with blacker spots or dashes on the veins. The forewing is shiny yellowish 

 grey, dusted with brown, no other lines (or only the median shade) distinct, fringes dark-spotted. Hindwmg 

 paler, the postmedian line discernible but often weak. The discal dot is wanting on both wings. Nefta, 

 Southern Tunis. Following OberthOr, the authors referred this species to Euacidalia. In the figure which 

 they give of the neuration the first subcostal of the forewing is represented as free, as in Gleta. In a series 

 of 8 larger examples from Hammam-es-Salahin, Algeria, bred by Lord Walsingham from Anabasis articulata 

 in March 1904, which I believe to be the same species, this vein anastomoses or is connected by a short 

 bar with the other subcostals. 



scabraria. Pt. scabraria Chret. Forewing elongate, distal margin strongly oblique; yellowish ochreous more or 



less strongly powdered with brown, the markings brown, more or less defined; shows the slight rosy reflection 

 so general in the Lspidoptera of Biskra ; first line acutely angled, becoming nearly parallel with the distal 

 margin; postmedian thick, ill-defmed, shadiiig off into the ground-colour, sinuous, subparallel with the distal 

 margin; median shade hardly broader than postmedian, sinuous; pale subterminal line undulate; distal border 

 uniformly pale yellowish ochreous; cell-spot more or less large and distinct, sometimes contiguous to the post- 

 median, sometimes removed from it; fringe reddish grey, marked with brown. Hindwing rather short, round- 

 ed at anal angle, very little emarginate between the radials, markings similar to those of forewmg. Forewing 

 beneath variable in the strength of the markings, which are often obsolescent ; sometimes, especially in the $, 

 the median and postmedian are more strongly expressed than above. ^ antenna described as "pectinate", 

 probably dentate; hindtibia apparently with very slender spurs. Egg a short, broad ellipsoid with small 

 oval depressions arranged in rows so as to form rather deep channels; colour whitish. Larva recalling in shape 

 that of infirmaria; short, thick, attenuated anteriorly, carinated laterally, segmental incisions not deep; skin 

 transversely folded, rugose and granulated ; dorsally greyish, laterally whitish with slight fleshy tint ; a double 

 blackish dorsal line, distinct only on the last segments; subdorsal sinuous, approaching the dorsal at the 

 incisions, forming a sort of lozenge-shaped pattern; a broad blackish brown dorsal spot in the middle of 

 the 2., 3. and 4. abdominals. The moth is probably double-brooded and occurs at Biskra, Algeria. 



tineaia. Pt. tineata Th.-Mieg should perhaps be placed here, as it is said to have elongate wings and to resem- 



ble scabraria. It is also said to "recall somewhat asellaria and pecharia", but this probably refers only to the 

 dusky colouring. "$ 12 to 17 mm. Rather dark grey, sprinkled with innumerable small black scales. These 

 black scales are so arranged as to form, on the forewing, 6 transverse lines, a little undulate and very vague. 

 On the hindwing are discernible, but with difficulty, 4 such lines, one a little before the discal dot and the 

 other 3 between this latter and the distal margin. A small black discal dot on each wing. The costa of the 

 forewing is a little shaded with blackish and 2 or 3 blackish spots are visible, indicating the commencement 

 of the lines. Some small black vein-dots at the distal margin, fringe long, agreeing with the ground-colour. 

 Under surface of the same shade as above, with the some lines, equally inconspicuous, and the dissal dots 

 as above. Pace and palpus blackish grey, vertex white, thorax and abdomen grey dotted with black, legs 

 grey, the hindleg with a sing e pair of spurs. Akbes (Syria), 5 $$." ' j
