PERIGRAPHA: MONIMA. By W. Warken. 89 



33. Genus: Perigrapha Led. 



Tongue developed: frons smooth; eyes with very long hair; antennae varying from bipectinated to 

 ciliated; thorax bearing a ridge-shaped dorsal crest; a dorsal crest on first segment of abdomen; abdomen 

 flattened, laterally rough-haired; in the hindwing veins 6, 7 are shortly stalked. The imagos appear in 

 early spring, frequenting sallow-bloom, like those of the following genus Momma. 



Type P. I-ci)icti(h) Schiff. 



Section I: Antennae in both sexes bipectinate to apex, the branches shorter in ?. 



P. circumducta Led. (21 h). Forewing pale olive grey, faintly flushed with pink, and dusted with circumduct a. 

 dark scales: median area chocolate brown, the costa remaining dark grey and the 3 conjoined stigmata, 

 which are sandy brown, concisely outlined in white; hindwing pale fuscous; thorax and tegulae chocolate 

 brown, the latter tipped with whitish. An Eastern species, occurring in S. Russia, the Altai Mts. in 

 W. Siberia, and in W. and E. Turkestan. 



P. I-cinctum Schiff. (= cincta F.) (21 i). Like circumducta, but darker grey, the contrast between I-cinctum. 

 the light and dark shades not so striking; the stigmata not white-edged; the orbicular not oblique; the 

 claviform shorter and broader; tegulae and thorax grey. Austria, Hungary, Ural Mts., S. Russia; Altai Mts., 

 W. Siberia. - Larva pinkish ; the dorsal , subdorsal , and lateral lines yellow, the last edged below with 

 orange: venter yellow; head red; on rumex and low plants. 



34. Genus: Monima Hbn. 



Differs from Perigrapha Led. only in the absence of the dorsal ridge on thorax and oi the crest 

 on first segment of abdomen. 



Tj'pe M. miniosa F. 



Section I: Antennae bipectinate to near apex in both sexes, the branches shorter in ?. 



M. carnipennis Btlr. (21 i). Forewing greyish luteous, with a slight flesh-coloured tinge; a coal- camipennis. 

 black spot at base below median vein and a dot on costa, representing basal line; inner and outer lines 

 hardly marked, except by a few black scales, and by the darker tint of the median area, conjoined on 

 submedian fold by a velvety black bar widened at each end; orbicular and reniform stigmata pale, large, 

 with still paler outlines, which sometimes contain black scales; submarginal line pale, sometimes accompanied 

 by black scales; hindwing whitish, sprinkled with grey towards termen; the veins darker; — ab. biconifer biconifer. 

 nor. (22a) has the inner and outer lines more approximated in submedian interval, where the typical long 

 black bar is reduced to two black cone-shaped marks, conjoined by their apices. Yokohama, Japan. 



M. rorida Friv. (22a). Forewing lilac grey, with a faint brownish flush, and thickly dusted with rorida. 

 black atoms ; lines ill-defined, starting from black costal dashes ; outer line finely dentate-lunulate, the teeth 

 marked by black dashes on veins; a diffuse tawny median shade, bent in middle, and passing over the 

 narrow grey-edged reniform stigma; hindwing ochreous grey, like the forewing peppered with black atoms; 

 fringe rufous ochreous; — in the ab. sieversi Christ, the lines are better defined, and the outer median sieversi. 

 area is tinged with pink. A South European species occurring in Istria, Dalmatia, Bulgaria, and S. Turkey; 

 in Armenia, Asia Minor, Syria, and Transcaucasia. 



Section II: Antennae of cf bipectinate, the apex serrate; of ? serrate throughout. 



M. porosa Ec. (22 a). Forewing fuscous grey; mottled with blackish markings; these are a black porosa. 

 spot at base below median vein, the cell, the claviform stigma, a small blotch before outer line on sub- 

 median fold, a costal patch before submarginal line, and another at middle; upper stigmata grey, flattened; 

 lines dark edged with grey, generally ill-defined; the submarginal line pale; hindwing paler grey, tinged 

 with luteous towards inner margin, with dark cloudy cellspot, outer line, and' submarginal shade. From 

 Sarepta and the Ural Mts. in S. E. Russia, and W. Turkestan. — Larva green with whitish lines, becoming 

 afterwards brownish lilac with paler marblings, and when fullfed much darker; feeding on Artemisia 

 and Tanacetum. 



M. gothica L. (= nun-atrum Hbn.) (22b). Forewing purplish red-brown; the lines pale, ill-defined, gothica. 

 except by black spots at costa; the cell black; stigmata pale and large; claviform connected with outer 

 line by a black bar; above which the base of vein 2 is often surrounded with rufous; hindwing fuscous. 

 The size of the orbicular stigma is variable, and the amount and shape of the black filling in of the cell 

 is determined by this variation ; — in ab. gothicina H.-Sch. (22 b) the black markings are replaced by gothicina. 

 olive brown or rufous; it is a northern form, occurring in Scotland, Scandinavia, and Finland, and in the 

 Tarbagatai Mts.: — askoldensis Stgr. from Amurland and Japan has a more violet grey ground colour; — askoldensis.
