14 GNOPHOSEMA; AGATHIA. By L. B. Protjt. 



virellata. some places (as southern Prance) 'but certainly occurs in others together with the type. - — virellata Krul., 

 from East Russia, perhaps truly a local race, would appear, from its author's description, to be closely 



fasciaia. similar to the last-named form, but larger and probably darker, less mixed with white. — As fasciata ab. nov. 

 may be described a handsome form of occasional occurrence (at least in Britain) with the hnes of forewing 

 somewhat approximated and the area between them considerably darker than the ground colour. The 

 larva of pruinata is stout, tapering anteriorly; head deeply bifid, the divisions pointed; prothorax pro- 

 duced to two points anteriorly, body nearly cyMndrical, with slight lateral flange, surface strongly granula- 

 ted with whitish; green with white subdorsal hnes, pink lateral hne and usually tipped with pink on the 

 points of head and prothorax and at anus; tubercles and setae dark, but minute. Hibernates small, and 

 feeds up rapidly in the spring. It may easily be found (by the practised eye) resting rigid and motionless 

 on the foodplants (especially Genista anghca), to the colour of which it is beautifully assimilated. Pupa of 

 moderate width, tapering anteriorly; hght brown or clay-coloured or greenish, irregulary dark-spotted, supra- 

 anal plate long. Rests in a very shght cocoon formed of a few threads among leaves. The moth appears in 

 the summer months and frequents heaths or moors, or open places in woods. It is easily disturbed by day, 

 but its flight-time is the night, when it is a frequent visitor to hght. It occurs throughout central and 

 south-eastern Europe and in Asia Minor. 



coronillaria. P. coroiiillaria Hhn. (1 f) supplants pruinata in south-western Europe and in Syria, and as the two 



seldom occur side by side the suggestion has occasionally been put forth that they are local races of a single 



species. The genitaha, however, present tangible differences, the ,,gnathos" (lower arm of the mandibulate 



uncus) being provided with much larger teeth in coronillaria, and it is therefore preferable to regard the 



last-named as distinct. The grey instead of green colour at once distinguishes coronillaria. The larvae are 



extremely similar, although pruinata, so far as I have observed, is somewhat the more brightly coloured 



larva, the tubercles somewhat less minute and darker coloured, spiracles somewhat more conspicuous. — ab. 



armora- armoraciaria Ob. (1 f) is a unicolorous dark aberration from S. W. France and Spain. — ab. axillaria Guen., 



ciaria. from Syria, also has the dark transverse hnes almost obsolete, but agrees in colour with the type. — cor- 



corsicaria. sicaria Bbr. (1 f) represents coronillaria in Corsica and Sardinia, and has usually been considered a separate 



species. It is said to differ from coronillaria in having longer antemial pectinations, a less black face, but 



darker fillet between the antennae and rather stronger abdominal crests. Larva with triangular white dorsal 



ornamentation, feeds exclusively on Genista cor sicaria, and in two generations. 



simplex. P. sXm^Xtx Alph. (3 a) from Central Asia has been regarded as a variety of p?"Mi?iato, but according to 



PtJNGELER (in htt.) is really a distinct species. It is of a uniform whitish green colour, and especially differs 

 from all the forms of pruinata in having the frons Avhite, only quite weakly tinged with brownish, whereas 

 in pruinata, as weU as in coronillaria, it is black. The size is perhaps on an average larger than that of 

 pruinata. 



8. Genus: Oiioplioseiiia Front. 



Palpus rather short, second joint densely scaled beneath. Tongue wanting. Antenna in S pectinate. 

 Hindtibia with terminal spm's only. Abdomen not appreciably crested. Wings shaped as in Pseudoterpna, 

 forcAving with second subcostal arising beyond fifth, hindwing with second subcostal short-stalked. Early 

 stages uiiknown. This genus is required for a single species, which was first described as a Gnophos, trans- 

 ferred to Boarmia by Hampson, but which, notwithstanding its colouring, certainly belongs to the present 

 subfamily. Unfortimately I have only seen two specimens, both $, and neither quite perfect. 



isometra. G. isoitietra Warr. Reddish-grey, irrorated with fuscous, both wings with a distinct cell-spot, 



that of the forewing large, sometimes ocellated, an indistinct denticulated postmedian hne and an inter- 

 rupted marginal line, foremng also with a dark spot on inner margin indicating the end of an obsolete 

 antemedian hne. Underside (especially of hindwing) paler, A\dthout markings. The first knowoi specimen was 

 from Akhor ( ? Akora), near Campbellpur. There is also an example from Kashmir in coll. Brit. Mus. Ap- 



-r parently fhes in April and May. 



9. Genus : Ag'atliia Guen. 

 We here commence a group of genera which are probably collaterally related to some of the earlier
