 marsh grasses, pupating in a spun cocoon. ah. flavida ami ah. albida of Auriv. (= ochracea and flavida.

the typeform, and from its appearance might well he a distinct species; the forewing is bronzy brown, 

 with all the veins and the fringe white: the head and thorax are brown; the abdomen and hindwings 

 white; this form occurs in Sweden and Dalmatia. being probably more widely distributed. 



13. Genus: I^eiometopoii Stgr. 



Antennae thick, lamellate, flattened: palpi short . hairy, with third segment minute; tongue absent; 

 eyes naked; abdomen without crests. 



L. simyrides Stgr. (2f). Forewing pale grey, with a broad white streak from base below median simvrides. 

 vein; according to Stauptnger, it much resembles S. dentinosa. It occurs only in Central Asia. 



E. Forewing grey varied with fuscous and black. 



14. Genus: Acronicta Tr. 



Antennae of cT pubescent; head, thorax, pectus and abdomen densely haired; the abdomen slightly 

 tufted near base, roughened laterally; palpi with third segment usually short; eyes naked; tongue strong; 

 vein 5 of hindwing weak, curved at base, from lower third of discocellular. — Larva adorned with long, 

 generally scattered , hairs ; resting in form of a horse-shoe ; tubercles small. — Pupa in cocoon in wood ; 

 the segmental margins smooth. — Eggs deposited singly. 



A. aceris L. (2g). Forewing whitish grey; basal streak thin and interrupted: a black streak through aceris. 

 outer line on submedian fold; hindwing white in cf, greyish in ?, the veins blackish. — Common throughout 

 Europe, extending through West and Central Asia. — ab. infuscata Haw. (2f) has the whole forewing infuscata.

 the figure, to be intermediate between it and the type, if it belong here at all: ab. intermedia Tutt (= can- intermedia. 

 delisequa Gn. nee Esp.) is the common British form, with forewing darker, tinged with ochreous, and more 

 distinct markings ; ab. judaea Stgr. from Palestine is paler, the forewing greyish white. — Larva with diffuse judaea. 

 tufts of long yellow or fulvous hairs; a dorsal series of snowwhite, purple-edged, diamond-shaped spots, 

 sometimes united by a white line: head black: fullfed in autumn: on sycamore and horse chestnut. 



A. albonigra Herz. Intermediate between strigosa and pontica, nearer the latter; the base of albonigra. 

 the forewing and a fascia beyond median shade blackish ; the rest pale grey ; orbicular stigma small, 

 whitish; reniform yellowish, as in strigosa; a black basal streak; hindwing shining greybrown; smaller than 

 strigosa ; Corea. 



A. alni L. (2g). Forewing pale grey; inner margin and a broad median shade black; hindwing alni. 

 white; generally distributed but rarely common. — The larva, when young, is whitish, with the middle 

 segments grey, being protected at this stage by its resemblance to a bird's droppings; when fullfed it 

 becomes purple black, the tubercles then bearing long black hairs with broadly thickened tips; the dorsum 

 marked on each segment with transverse yellow bands; in this stage it is said to emit a strong scent; — 

 fullfed in autumn, on oak, alder, etc. — In the ab. steinerti Cusp, the ground colour is dark brownish steinerti. 

 grey; ab. carola Phil, representing an intermediate form; in ab. suffusa Tutt the two pale patches are as carola - 

 dark as the rest of wing; in ab. obsoleta Tutt the orbicular stigma is wanting. obsoleta 



A. asiatica Pouj. Differs from aceris L. in having the forewing more square; the orbicular stigma asiatica. 

 conspicuously white on a grey ground: the whole wing with a rufous tinge; recorded only from Moupin, 

 W. China. 



A. bellula Alph. Forewing uniform dark ashy grey: the markings finely black; the orbicular bellula. 

 stigma pale: described from a single c? from Sidemi. 



A. carbonaria Graes. (= brumosa Leech) (2h). Forewing elongate, like a large runnels, fuscous carbonaria. 

 black; a pale patch at base of inner margin; hindwing whitish, darker at base: found in Amurland by 

 Graeser; Leech's so-called brumosa from Japan and Corea. 



A. catocaloida Graes. (2h). Forewing greyish black, much broken up by obscure dark and light catocaloida.
