132 AGRIOPIS. By W. Warren. 



baltica. C. baltica Hering (= vulturina H. Sch.) (32 d). Forewing uniform rufous grey; only the median area 



•with the markings distinct and the black brown shading present; the stigmata unicolorous, not marked 

 with white; the wedge-shaped marks before submarginal line absent; hindwing dull grey in both sexes, paler 

 towards base. In North Germany, Finland, and the Baltic provinces of Russia. 



sommeri. C. sommeri Lef. (= groenlandica Zett., picticollis Zett., surtur H.Sch.) (28 d). Resembles adusta, but without 



any brown admixture, the tints being grey and fuscous. This type form was described from Greenland and Labrador; 



islandiae. the ab. islandiae Mill., from Iceland, the Faroe Islands, and Lapland is brighter coloured, the forewing being more 

 or less tinged with redbrown. Larva rosy brown above, yellow ventrally, with slender dark brown lines; 

 spiracles white with dark rings; head and feet yellow; on various low plants. 



hniia. C. lama Stgr. (32 d). Forewing grey dusted with darker, and partly suffused with pale brown, espe- 



cially beyond outer line; the lines and markings much as in the preceding species, but without any black- 

 brown shading; hindwing greyish, darker along termen. W. and E. Turkestan. 



haasi. C. haasi Stgr. Described as an Aporophyla, and differentiated from A. nigra by the forewing not 



being deep black, but partly mixed with redbrown, with more distinct markings. Spain, Castile. 



39. Genus: Agriopis Bsd. 



Tongue present ; palpi ■ obliquely porrect, hairy in front, the terminal segment smooth, depressedy 

 antennae of $ shortly ciliated; abdomen tufted at base and laterally fringed with hair; characterised especiallg 

 by the fore femora, which are greatly dilated. Larva thick and fleshy, mottled ; feeding on Quercus and restin ; 

 by day in the chinks of the bark, the colour of which it mimics: the larvae feed up in early summer, the 

 imagos emerging in autumn. Type Agriopis aprilina L. 



aprilina. A. aprilina L. (= runica Schiff.) (32 d). Forewing whitish green; lines and markings velvety black, 



the median shade especially thick; upper stigmata large; all the black markings emphasised by white; hind- 

 wing blackish grey; the cellspot, outer line, and submarginal shade darker; a white terminal space before 

 bouveti. the black marginal line; the ab. bouveti Lucas, from France, has the head, thorax, and forewings greener, 

 the median area of forewing without black markings. Generally spread throughout Europe and occurring 

 in Asia Minor. Larva greenish black, with a fulvous tinge; a dorsal series of dark medallions; dorsal line 

 pale, interrupted, with black edges; spiracular line pale like the venter; on Quercus robur. 



aeruginea. A. aeruginea Hbn. (32 e). Forewing dull purplish grey; a patch at base of costa and the two upper 



stigmata pale grey green edged with black; a black streak from base below cell with some yellow scales at end; 

 claviform stigma of the ground colour followed by a pale patch before the black incised outer line which 

 is succeeded by a yellow patch followed by a black patch cut by the wavy pale submarginal line, which is 

 often marked by greenish or yellowish scales; costa with lichen-grey intervals between the darker lines; hind- 

 wing in $ white, with a subterminal grey shade; the cell spot and veins darker; in $ uniform brownish fuscous 

 mioleuca. whiter along costa; in the form mioleuca Hbn. (= chioleuca Tr.) (32 e), the whole forewing is suffused with 

 purplish grey, and the greenish white and yellowish scales are all obscured. Found in France, Germany, 

 Austria, Hungary, Italy, Dalmatia, Bulgaria, Galicia, and in Asia Minor. Larva pale yellow; dorsal line 

 pale, intersecting a series of spade-shaped spots; subdorsal and spiracular lines yellowish; on Quercus 

 pubescens. 



eonvergens. A. eonvergens F. (= spicula Esp.) (2 e). Differs from aeruginea in being pale ashgrey, paler in 



the <$, suffused with dark grey, particularly in the central area; the black basal streak prominent, with a pale 

 grey patch above it; the upper stigmata rather paler than the ground colour, the claviform concolorous; the 

 patch above submedian fold, beyond a whitish crescent in the outer line, always ferruginous; hindwing grey, 

 darker in $. A south European species recorded from France, Germany, Austria, Hungary, Switzerland, 

 N. Italy, and Bulgaria. Larva sand-coloured; dorsal line distinct, whitish, with redbrown edging; on each 

 side of it irregular redbrown or blackish blotches with two white dots in their duller centres; laterally washed 

 with brown, with separate white dots; spiracular line yellowish white; feeding on Quercus. 



pryeri. A. pryeri Leech (32 f). Forewing purplish grey, varied with paler, not uniformly dark as in aeruginea, 



and suffused throughout with dull olive; the lines and markings as in the preceding species; the upper stigmata 

 larger and paler grey, the claviform dark, followed by a conspicuously paler and larger subquadrate patch; 

 submarginal line pale marked with olive green scales; hindwing grey, paler in the <J; altogether a more 

 roughly and coarsely scaled insect than the preceding species. Japan.
