18 GHAMAEPORA. By W. Warren. 



rosea, greyish band across renewing before the middle; and ab. rosea Tutt has the forewing suffused with rosy; 

 juncta. lastly, ab. juncta Tutt shows the two stigmata with their inner edges united. 



raphael. A. raphael Oberth. (= fixseni Graes.) (3e). Forewing bluish grey, crossed by coarse grey blotches 



and fasciae; a black streak from base with paler patch above; found only in Amurland. 



senka. A. senica Ev. (Be). Forewing bluish grey; costa with two black blotches; two black horizontal 



marks, convex to each other, on veins 1 and 2. Occurring in the Ural and Altai Mts. ; the above (p. 15) 

 mentioned A. literata Brim, from E. Siberia must be very near this species, possibly identical, with the 

 costal blotches absent (? abraded). ■ - x-signata Stgr. (see below), also from S. E. Siberia, ma}- represent 

 a strongly marked form, in which the contact of the swollen horizontal streaks produces the long x-shaped 

 marking from which it derives its name; all three insects are of the same size, 35 mm. 



sinens. A. sinens If Ik. Forewing chalkwhite; the lines olive grey, black on costa; a thick black basal 



dash ; the lines connected by a black and grey shade on submedian fold ; a black spot at end of vein 2 

 on both wings; Leech records one specimen from West China of this small Indian insect. 



strigosa. A. strigosa F. (= favillacea Esp.) (3e). Forewing pale grey, tinged with ochreous; base of inner 



margin yellow: reniform stigma externally yellowish; a broken black streak along submedian fold; not a 

 common species, but occurring throughout Europe, in Armenia, Amurland, Japan and Gorea. — Larva 

 velvety green, with broad redbrown dorsal band; hairs scattered and fine; dorsum humped on segment 12; 

 like the larva of Centra, which it resembles superficial^ in colour and ornamentation, it changes from 

 green to dull purplish before spinning up; fullfed in autumn; on hawthorn, which is its only foodplant in 

 bryo- Britain, though conlinental writers give sloe and Rhamnus. — ab. bryophiloides Horm. (— casparii Uteinert) 



philoides. (3 e ) is a smaller form with the forewings wholly dark grey. -- Japanese specimens are considerably larger 

 than European and much darker; the stigmata more strongly indicated, and the black dashes thicker; they 

 adaucta. may be distinguished as adaucta subsp. nov. (3e). 



subornata. A. subornata Leech (3f). Forewing dark grey, clouded with black, and here and there varied with 



whitish; a whitish costal patch near base; submarginal line interruptedly whitish; hindwing dark fuscous. 

 Occurs in Japan and Gorea; resembling carbonaria Graes. and nigricans Leech, but distinguished by the dark 

 hindwing. 



subviridis. A. subviridis Btlr. (3f). Forewing silvery grey, with various dark markings; the whole wing 



blotched with pale green; submarginal line greenish-white, preceded by a broad green band; inhabits 

 Japan and W. China. 



terrigena. A. terrigena Graes. This species, described from a single ¥ from Amurland, is stated to be inter- 



mediate between strigosa and tridens; it is possibly a small example of fasciata Moore. 



tridens. A. tridens Schiff. (3f). Externally indistinguishable in the imago stage from dark forms of psi, 



but the grey always seems browner; occurs throughout Europe, and in Amurland; also recorded from 



Japan, but these specimens seem rather referable to intermedia (= increta Btlr.). — Larva black and red: 



a white dorsal stripe with a series of orange red spots; a broad white spiracular line, and a row of red 



and white marks along the sides; hairs darker and longer than in psi; segment 5 of dorsum with a tuft of 



black hairs; 5 and 12 both slightly humped; fullfed in autumn, on hawthorn and various trees. — ab. 



virga. virga Tutt is a form with the hindmargin darker, corresponding to the ab. bivirga of psi; ab. rosea Tutt 



rosea. y, as the wings suffused with rosy; in ab. bidens Tutt the basal dagger has no handle; while in ab. 



quinque- 1 u i nc l ue dentata Tutt the handle part is produced through a second bifurcation; lastly in ab. juncta Tutt 



dentata. *' ie two stigmata have their inner edges united. 



\--sisrttita ^' x " s 'S na ta Stgr. Forewing dark grey, crossed by fine curved black lines, united on submedian 



fold by a black streak to form a long x-shaped marking; in marginal area are two rows of black streaks, 

 one only, in the inner row, being conspicuous; described from S. E. Siberia and possibly, as remarked 

 above, a dark well-marked form of senica Ev. . 



15. Gemis: Cliamaepora nov. gen. 



Distinguished from Acronicta by the larva bearing fascicles of short stiff hairs, rising from enlarged 

 tubercles; larva stout and thick, resting extended, not coiled round, and feeding on various low plants. — 

 Pupa in a spun cocoon, with the segmental margins ridged. — Eggs laid in a mass. Type: C. rumicis L. 



icoma. C. auricoma F. (31). Forewing grey, with dark dusting; base of inner margin pale ochreous; a 



short black basal streak and another above anal angle, often obscure: flies in May and again in August, 



pepli. occurring tluoughout Europe, and in Armenia, extending into Siberia. — The ab.' pepli Htm. (= pyhae-
