DASEOGHAETA; DIPHTHEROGOME ; DIPHTHERA; GOLOGASIA. By W. Wabeen. II 



4. Genus: Daseocbaeta gen. nor. 



Antennae of <f with short stiff ciliated pectinations, towards apex serrate; of? finely serrate and 

 pubescent; head, face, palpi, pectus, abdomen and legs rough-haired, as in Oaycesta lll»/.: palpi short, 

 drooping; tongue well-developed: abdomen without crests: eyes naked; vein 5 of hindwing curved at base, 

 from lower third of discocellular. 



D. viridis Leech ('2b). Forewing dingy grey-green; markings black, with pale edges: the 3 lines viridis. 

 wavy, the outer approaching distal margin; reniform stigma large, roughly 8-shaped; hindwing dirty grey; 

 the wings are rather glossy in both sexes, generally paler in the d*. — Recorded by Leech from Japan, 

 as Agriopis. 



5. Genus: IMphtlierocoine gen. nov. 



Differs from Diphthera in having the antennae of <? bipectinated. 



D. pallida Moore (2b). Forewing sea-green, paler between the lines, and white along the folds ; pallida. 

 the lines black and thick: a black blotch between stigmata: a row of dark submarginal spots; hindwing 

 greenish white. — Recorded from West China; also from India and Kashmir. — In West China there occur 

 two forms, both distinct from the typical; ab. laevis nor. , as large as type-form, has the black markings laevis. 

 reduced, the outer line nearer middle of wing, and no submarginal spots; the other form, ab. minor nov., minor. 

 is distinctly smaller, has the black markings intensified, the outer line closer to distal margin, and the 

 hindwing in both sexes tinged with smoky grey: these forms were referred by Leech to vigens Walk., but 

 that Indian species is cmite distinct. 



D. vivida Leech (2b). Forewing yellower green than in pallida , the lines finer; submarginal spots vivida. 

 nearer distal margin. — West China. 



6. Genus: Diphthera TV. 



Antennae of <? lamellate, pubescent; head, thorax, and pectus hairy; palpi upturned, hairy; third 

 segment long, smooth, acute: tongue developed; eyes naked; patagia and metathorax crested; vein 5 of 

 hindwing straight, from just below middle of discocellular. 



D. alpium Osb. (= orion Esp.) (2c). Forewing bluegreen, the costa and both folds white: stigmata alpium. 

 and lines black; outer hue with brown outer border; hindwing fuscous, with black and white marks at anal 

 angle; widely distributed, but local, flying in May and June. — In the form murrhina Grues. (2c), from murrhina. 

 Western Asia , the green of the forewing is much more broken up by black markings between the lines, 

 and the brown shade beyond outer line is wider and extends into the fringe. — The examples from Japan 

 are as large as European, those from Gorea decidedl}- smaller. Larva pale brown streaked with yellow; 

 dorsum black with 3 transverse yellowish white blotches; tubercles reddish, bearing erect tufts of hairs; 

 feeds up in autumn, on oak. 



D. marmorea Leech (2b). Forewing bright green; basal patch brown, angularly produced below marmorea. 

 a brown shade beyond outer line followed bj T a submarginal row of spots: hindwing whitish. — 



middle ; 



West China. 



G. Forewings fawn-colour or reddish. 



7. Genus: Colocasia TTbn. 



Antennae of ri* bipectinate, of ? simple ; head, thorax, and pectus hairy ; palpi hairy, porrect, terminal 

 segment small; tongue slight; vein 5 of hindwing strong, straight from near middle of discocellular; 

 veins 6. 7, and 3, 4 short-stalked. 



C. coryli L. (2 c). Forewing pearly grey, tinged with brown ; lines blackish, vertical ; space between coryli. 

 them often dark brown. Of general distribution, occurring in May, throughout Europe, also in Asia Minor. — 

 The form mus Oberth. (2 c) from Amurland has the ground-colour more bluish grey. — Larva ochreous, mus. 

 with grey hairs; dorsal line dark, with two long projecting pencils of black hairs from segment 2 and one 

 from segment 12., two reddish brown erect tufts on segments 5 and 6: feeds up in autumn on various 

 trees. The genus seems better placed with the Ocneriidae, with which it agrees in the larval tuftings.
