28 AGLOSSOCHLORIS. By L. B. Prout. 



Hindwing without lines, the green ground-colour shading off to whitish towards costal margin and base. — 



obsoleta. In ab. obsoleta Burr, the discal spot is wanting. — In ab. alinea Burr. ( ? = immaculata Thunb.) the white 



ahnea. li^eg are entirely absent. — ab. unilinea Burr, possesses the postmedian line only. — ab. caeruleo-viridis Burr. 



caeruleo- is of a decided blue-green ground-colour. — ab. viridis Burr, is of an unusually vivid green. — gigantea Mill. 



mridis. (= castiliaria Stgr.) is a very large form from Castile and Aragon with the lines indistinct or wanting. — 



In Britain the larva feeds only on Artemisia maritima, and is confined to salt marshes; on the continent its 



habits and foodplants are more varied. It has a wide range in Europe and perhaps in Asia, but the Asiatic 



material which I have seen is referable to prasinaria. 



viridis, 

 gigantea. 



prasinaria. E. prasinaria Ev. (= volgaria Ghien.) (2f) is very usually regarded as a form of the preceding, but 



I incline to the opinion of Millie re and a few others, that it is a distinct species. It is generally smaller, re- 

 latively longer-winged, the transverse lines very broad and very white, the postmedian markedly serrate, the 

 hindwing often more whitish both above and beneath, the distal half remaining greenish, traversed by a 

 distinct white line. It inhabits South-east Russia and has in Asia a tolerably wide range, from Trans- 

 mongolica. caucasia through North Persia and as far eastward as the Uliassutai district. — mongolica Stgr. is said 

 to be darker green, the white lines almost twice as broad, the white Unes and spot on the underside of both 

 wings also larger and broader. It is only recorded from the Uliassutai district in northern Mongolia, but I 

 have a specimen of prasinaria from Amurland agreeing with the description. 



chloro- E. chlorophyllariai7e(^. (3 b) is of nearly the same colour a,s smaragdaria and prasinaria,h\it vevy distinct 



phyllana. jj^ having the lines straight, not lunulate or denticulate, and in lacking entirely the white discal spot. Oc- 

 curs in S. E. Siberia, N. China and the Amdo district (S. E. of Koko Nor). 



janlcoivs- E. jankowsklaria Mill. (2 f ) is extremely near the preceding, to which it has been sunk by Leech. It 



kiana. jg j^q^^ ^q entirely grass-green, being more mixed with white scales and having a white patch at the base of the 



hindwing. According to Millie re the lines are still straighter than in chlorophyllaria. His figure looks 



smarag- slightly shorter-winged. Known only from S. E. Siberia. — smaragdularia Stgr. from southern Ferghana is 



dulana. possibly a form of jankoivskiaria, but seems to have longer distal margin and some other slight differences. 



The antemedian line is usually very weak, sometimes wanting, the discal spot of smaragdaria is occasionally 



viridifrons. traceable, the postmedian line is slightly outcurved. — viridifrons Warr., erected on a single specimen from 



near Dinau (Amu Daria) is probably a strongly-marked form of smaragdularia, with the antemedian line 



and cell-spot distinct. 



alboeostaria. E. albocostaria Brem. (2 h) is a very distinct species, easily recognized by the very large, reddish- 



centred (and often reddish-edged) discal spots or patches, red marginal line and red-spotted white fringes, 

 recalling certain species of Comibaena. Common in Japan, occurs also in South-east Siberia. Probably double- 

 brooded. 



serraria. E. serraria Stgr., founded on a single example (9) from Transalai, and originally suggested as pos- 



sibly a variety of smaragdaria but more likely a separate species, was later considered by its author to be 

 perhaps a variety or aberration of plusiaria. The postmedian line is very strongly dentate, and there is 

 a white submarginal line present which, on the underside of the hindwing, becomes strongly dentate. 



plusiaria. E. plusiaria Bdv. (2 f) bears superficially far more resemblance to an Aglossochloris than to smaragdaria, 



the hindwing being in great part white above, while the forewing above and both wings beneath have much 

 broadened, more zigzag white lines and a series of large white submarginal wedge-spots, connected into a 

 zigzag line on the under surface. The species is very local, and confined to Spain and North Africa. 



29. Genus : Aglossochloris Prout. 



Closely related to the preceding genus, differing chiefly in the absence of the tongue and in the hind- 

 tibial armature. This is very remarkable, the $ (at least in all the specimens which I have been able to 

 examine, or concerning which I have obtained information) wanting the proximal pair of spurs, while in the 

 cj the armature is variable, these spurs being present, but aborted, in fulminaria, but absent in the other 

 species. The larval habits are identical with those of Euchloris. The genus may be treated as entirely Pa- 

 learctic, for even the single Indian species inhabits Kulu and other northern localities in that country.
