BOARMIA. By L. B. Prout. 



lucialata except on geographical grounds. Whitish, the white cell-mark not or scarcely dark-ringed, subbasal 

 band Avell developed, postmedian line rather weak except on the veins. Larva smooth, light green with bluish 

 green and white longitudinal lines. On birch, sallow, heath and various other plants. The pupa hibernates 

 and the moth appears in April — May. Widely distributed from Spain to Japan, in the more central latitudes 

 of the Region. 



rhomboida- B. rhomboidaria Schiff. (= gemmaria Brahm) (20 g). Violet-grey much shaded with brown and dusted 



'*"■ with blackish, the appearing rougher than perversaria, which it resembles in the course of the lines. Underside 

 more whitish, very variable in the amount of dark dusting, which tends to become stronger anteriorly and 

 generally forms a dark patch near the apex of the forewing, leaving free a spot at the apex itself and one be- 

 ausiralaria. hind the 3rd radial. — ■ ab. australaria Curt, has a strong bright ochreous admixture and sharp markings. I 

 fimbriaria. have only seen it from S. England. — ■ ab. fimbriaria Steph. is an extraordinary aberration with the ground- 

 colour very light yellow-brown, scarcely dark dusted, the entire distal area of both wings dark fuscous. • — 

 millierata. ab. tnillierata Gmpbg. is transitional, smoky grey, the lines normal, the entire distal area moderately infuscated, 

 perfumaria. but with the subterminal line, however, indicated. — perftittiaria Neivman is almost entirely Avithout the brown 

 admixture, the violet-grey ground-colom' often darkened. A local race in London, etc., but known as an aber- 

 rebeli. ration in France. — ab. rebeli Aigner is almost entirely unicolorous, blackish. Traces of a pale outer line usually 

 minor, remain on the forewing. — gen. aest. minor Fuchs scarcely differs from the principal form except in the con- 

 siderably smaller size. — Egg pink, cylindrical, equally suddenly rounded off at both ends, with thick and 

 regular ribs longitudinally and thin sharp ones transversely ; the stellate area shows the usual hexagonal pitting, 

 with glowing white knobs at the angles. Larva elongate, twiglike, with slight lateral protuberances on the 

 2nd abdominal; colour adaptive to the branches on which it rests, sometimes unicolorous, sometimes with dorsal 

 lozenges. Polj'phagous, hibernating. Pupa rather slender, deep red-brown, the wings mottled with blackish. 

 Partially double-brooded, common in a great part of Europe, also Syria, Transcaucasia, Persia and the Altai. 



psoralaria. B. psoralaria Mill. (= consimUaria Mill, nee Dtip.) is a littleknown species which has been confused 



with rhomboidaria but is clearly distinct, the egg hibernating and the larva lacking the lateral projections. 

 The perfect insect is smaller, more greyish, the abdomen ringed with black; Millieees figure shows also 2 

 characteristic dark streaks (costal and subcostal) distally to the subterminal line of the forewing. Larva cylin- 

 drical, head flattened in front; clay-coloured, with interrupted broMm longitudinal lines, spiracular line rather 

 pale, undulate, continuous; venter partly whitish. On Psoralea bituminosa, Malva and Cj^tisus, May to the 

 end of July. Cannes. 



flavolinearia. B. flavoliiiearia Leech (20 f ). A striking species and quite isolated. Antenna of ^ rather short, with 



long pectinations, cell of forewing slightly longer than usual. Distinguishable at a glance by the light yellow, 

 ochreous-edged lines. Japan, apparently rare. 



nooraria. B. nooraria Brem. (25 g). Dirty light yellowish, irrorated with blackish, the lines olivaceous fuscous, 



the median and postmedian on both wings dentate, parallel, approximated, some dark dusting between them 

 forming a sort of band. Distal area nearly as in the following. Ussm'i district. 



deeoloraria. B. decoloraria Leech (20 g). Probably closely related to nooraria, which I do not know in nature; 



it might even be identical but that the postmedian line of the forewing is quite differently formed and the 

 median area not darkened except at the hindniargin of the forewing. Forewing beneath sufused with olive- 

 brownish, distally pale between the veins; hindwing paler, rather uniformly irrorated, the lines very weak; 

 both wings with distinct cell-dot. Central and W. China. 



dissimilis. B. dissimilis Stgr. (24 c) ^ unicnown. 2 of the size and shape of the following, grey with dark dustuig. 



without the brown tinge of the allied species; antemedian line oi forewing strongly curved outwards, post- 

 median almost right-angled on 3rd radial, then very strongly incurved, bending outwards again (more strongly 

 than in secundaria) at hindmargin. Underside light grey with cell-Tiiarks and postmedian lijie. Ussuri district. 

 ? Japan. 



manuelaria. B. manuelaria H.-Sch. (26 g). Rather similar to secundaria, forewing with distal margin more oblique, 



colour more olivaceous brown, or even almost green, postmedian line of hindwmg fine and generally sharp, 

 hnehneri. placed comparatively near the distal margin. Antennal pectinations slightly fiisiform. — ab. huebneri n^m. 

 nov. (= licaria Hbn.-Gey. nee Vill.) is darker, 'ess greenish. — Egg elongate, green at first, changing to dark 

 purplish, on strong magnification seen to be marked with longitudinal sulci, the transverse being still slighter. 

 Larva greenish grey with black, lozenge-shaped dorsal markings and oblique dark lateral dashes accompanied 

 by yellowish shading. On oak, probably hibernating, full fed in May or June. Moth in July — August, very 

 local, Spain, Portugal. S. France, W. Germany and Dalmatia.
