90 PTYCHOPODA. By L. B. Prout. 



the presence or absence of spurs on the (J hindtibia; but it is unfortunately quite certain, especially from the 

 curious case of rusticata and vulpinaria, that this gives only an artificial classification ia some instances. 



A. Section Sterrha. ^ hindtibia with terminal spurs present. \ i 



aureolaria. Pt. aureolaria Schiff. (= trilineata Scop, nee Hufn. = bicincta Geoff.) (4 a). Bright golden yellow, 



the extreme costal edge of the forewing black. Forewing with three, hindwing with two sharply defiaed grey 

 or blackish lines, all nearly straight, or the inner line of the forewing or the outer of the hindwing may be 

 slightly more irregular. Distal marginal line black, basal part of fringes blackish, their extremities paler. 

 Under surface similar, forewing without the first Ime but sometimes with a little blackish dusting in basal 

 area, both wings with a small black discal spot close proximally to (often touching) the median line. Even 

 in the most weakly marked specimens (generally 2$) the lines are more sharply defmed than in the similar 



mgrrocostofo. species. — ab. nigrocostata Hirschke has on the upper surface a broad black costal stripe on the forewing 

 and black basal streak on the hindwing ; beneath the black costal area of the forewing is stUl further extended 

 and both wmgs have the basal area blackened. Described from a single c? from Austria. — The larva is one 

 of the more slender in the genus, the lateral ridge sharp; it is reddish grey, the fine white dorsal line edged 

 with black, the subdorsal line almost obsolete, but expanding into a dark spot at each segment-incision. 

 Tubercles very small, only more distinct on the thoracic segments. The pupa is yellowish, with the cremaster 

 dark; according to Rogenhofer with four curved-tipped bristles, but probably two had become broken 

 or were overlooked; Rebel says "five or six". Double brooded, occurring tlurough June and into July 

 and again in August. It has a moderately extended range in Central and Southern Europe, especially in the 

 more eastern parts, and reappears in Central A da along the mountain ranges from Armenia to Mongolia. 



luieolaria. Pt. luteolaria Const. (4 a). Less brightly coloured than the preceding. Usually reddish ochreous, 



very rarely yellow, and even then not so golden as aureolaria. The lines red-brown, hence much less prominent, 

 only the postmedian sometimes more fuscous-mixed. A slight reddish shade usually follows the postmedian 

 and to this succeeds an indistinctly pale subtermmal line. The fringes in strongly-marked examples are 

 very varied, at their base reddish, then nearly black, then with a very fine whitish line and finally grey. On 

 the under surface the median and postmedian lines are tliickened and blackened and the rufous shading which 

 follows the latter is usually dusted with black. A very local species, inhabitmg the Pyrenees and the mountains 

 of Spain. I have it from various Spanish localities, collected by Dr. Chapman in July. It first appears, 

 however, in June or even in May and there is a partial second brood in the autumn. Larva rather short 

 and thick, attenuated anteriorly, head small, brown ; body ochreous, browner at the incisions, with an X-sha- 

 ped black dorsal pattern on the middle segments; the whitish lateral line fine and interrupted; spiracles mi- 

 nute, not noticeable without a lens; no ventral line, but two small diagonal brown marks on each of the 

 middle segments. Polyphagous but seems to show a preference for the petals of Geranium and other flowers. 



falckii. Pt. falckii Hedem. (= falcki Stgr.) from Amurland, is unknown to me. It is said to belong in the au- 



reolaria group, but the structure of the $ hindleg is not expressly mentioned. The ^ is red-brown, darker 

 towards the distal margin, the $ very variable in colour, lighter reddish brown to clay-yellowish. The fore- 

 wing has three, the hindwing two blackish brown transverse lines and a fine blackish distal marginal line. 

 The fringes are broadly black-brown in the middle, basally and at their extremities grey, in the $ tinged 

 with yellowish. The Imes are curved anteriorly, that of the hindwing more waved. Underside dusted with 

 red-brown, especially in the distal area, the median and postmedian lines thicker than above, the first line 

 wanting. 



ochrata. Pt. ochrata Scop. (= corrigata F. = pallidaria Hhn. = ochrearia Hhn. = perochraria Dhld., nee 



F. R.) (4 a). Reddish ochreous with the lines more reddish, seldom very sharply defined; the basal and me- 

 dian usually rather thick, the postmedian finer. Fore\vtng with first line gently curved or strongly bent, often 

 weak or obsolete; median line sometimes a little curved near costal margin; postmedian parallel with distal 

 margin, very faintly wavy or denticulate; two moderately distinct lines or shades enclose the pale subter- 

 minal. Frmge with dark dots opposite the veins, though very variable in intensity. Hindwing without the 

 first line, the postmedian more sinuous. A minute dark discal dot is usually discernible on the hindwing 

 and very occasionally on the forewing. On both wings the area between the median and postmedian lines is 

 usually somewhat clearer than the rest. The under surface is more strongly dark dusted; as a rule only the 

 subterminal line remains altogether free from the dusting; the lines and shades, except the first line of the 

 forewing, are better expressed, in well marked specimens very dark. An abundant species in Central and 

 Southern Europe and extending eastward as far as Transcaspia; June — August. It is very variable in size
