20 COMIB^NA. By L. B. Protjt. 



special favour given this species a disguise in order the better to secure it in the larval stage against the birds 

 and ichneumons ?" The pupa is brown, the surface dull and rugose, the dorsal area of the posterior abdominal 

 segments bearing numerous flattened, spines, pointing backwards; spiracles large and dark; anal armature con- 

 sisting of four strong, scythe-shaped, spirally curved hooks. The moth appears in June and July, and fhes 

 at about sunset on the edges or along the glades of woods, usually at a considerable height above the ground. 

 The range of variation is not great, but the markings vary in extent. Central and Southern Europe, Asia Minor. 



neriaria. C. neriaria H.-Sch. (2 b) differs from pustulata in the longer palpus, the very short stalking of the second 



subcostal of hindwing and some other details of structure ; also in the presence of a white, red-margined dorsal 

 spot on second abdominal segment, the reduction of the marginal blotches and the angulation of the postmedian 

 line. Underside rather variable, that of hindwing often nearly white. Occurs from Greece to Armenia. Is very 

 inexcusably treated by Staudingbe as a variety of pustulata. 



procumbaria. C. procumbaria Fryer (= vaga Btlr.) (2 b). Similar to neriaria, but with the hnes almost obliterated, 



the spot at anal angle of forewing rather larger, enclosing one white spot (not, as in neriaria, two), hindwing 

 with a rather large apical blotch, its white centre intersected by red on the veins. Shanghai and Japan, also 

 once taken at Omei-Shan. Appears in June. 



tenuisaria. C. tenuisaria Gh-aes. (3 c). Nearly related to the two preceding, especially to procumbaria, with which 



it nearly accords in the blotches. Lines present, formed about as in neriaria, abdomen with dorsal spot as in 

 that species, followedby a smaller white one on the third segment. Crown ofhead green, not white as in neriaria. 

 The larva feeds on Quercus mongolica in June, but has not been described. The moth flies in July, and in- 

 habits South-east Siberia. 



anwenaria. C. atnoenaria Ob. (2 c) is again similar, but has the postmedian line more oblique, running nearer to 



the anal angle, and the marginal blotches reduced to a pair of small reddish spots at the anal angle of the fore- 

 wing and a similar pair at the apex of the hindwing. The species was first taken on the Isle of Askold, and 

 occurs in the same district as tenuisaria, and also in Japan. It fhes in July. 



tancrei. C. taticrei Graes. (3 a). A very distinct species, although structurally quite closely related to the prece- 



ding group. It is at once distinguished from all the other species by the course of the white hnes, the ante- 

 median being broad and oblique outwards, the postmedian curved so as to approach the antemedian on the 

 posterior (inner) margin, where the two are connected by a white line. This species is confined, so far as is at 

 present known, to the Amur and Ussuri districts. 



obsoletaria. C. obsoletaria Leech (2 a). Distinct from all the preceding in that there are no marginal blotches, the 



pale fringe being merely preceded by a red-brown marginal hne. The postmedian line is bent near the costa 

 but less angularly than in neriaria. Eaushiu in June. 



striataria. C. striataria Leech (2 c) is more thinly scaled and is conspicuously striated with silvery white. Other- 



wise without markings. Under surface whiter. Che-tou, West China. 



delineata. C. delineata Warr., in which likewise the wings are strigulated with silvery, has the hnes present on the 



forewing, usually yellowish, in part edged with reddish, the postmedian I'etracted along second median vein, 

 but is further characterized by having a pale pink blotch and some black dots at anal angle of hindwing. Ori- 

 ginally described from Sikkim, but occurs also in Tibet. 



f 



apicipicta. C. apicipicta Prout (3e). Wings of the same green as in delineata, and similarly strigulated with silvery; 



wholly without hnes. Forewing with minute black discal dot and dull reddish marginal line, fringe yellowish 

 green. Hindwing with the discal dot sometimes larger, marginal hne becoming black apically (interrupted at 

 vein-ends) and accompanied proximally, between second subcostal and first radial, by a small, bright pink 

 blotch. Under surface much whiter, without the pink blotch. Yatung, Tibet. Type and two others (all (JcJ) 

 in coll. Brit. Mus. Certainly a near relative of delineata. 



argeniaiarin. C. argetltataria Leech (2 b). Bright green, forewing with two silvery white hnes, the antemedian bi- 



curved, the postmedian irregular, expanding into a broad dentate mark at inner margin, followed by a red-brown 

 blotch at anal angle, a dark discal dot ringed with white. Hindwing with discal mark elongate, a white sub- 

 marginal line of irregular course, followed, especially towards apex, by red-brown blotching; cell-mark large, 

 elongate. Underside of forewing without antemedian line; of hind wing silvery white, wit li a red-brown patch at apex
