PuU. 31. VI J. 1915. ■ BOARMIA. By L. B. Prout. 369 



B. basifasciaria Leech (20 g as hasifuscaria). A rather broad-wiuged species, very distinct in the strongly basifascia- 

 sinuous median hne and the dark band between this and the antemedian hne, continued, though less darkly, to »"'« 



the base. Japan: Oiwake. 



B. angulifera Btlr. (20 g) has approximately the same markings as repandata but is considerably smaller, angulifera. 

 median area of forewing mostly pale, proximal and distal areas darkened, subtermmal line rather deeply lunu- 

 late-dentate, almost parallel with distal margin throughout, strongly dark-shaded proximally. Hindwing 

 rather weakly marked. Forewing beneath with dark distal-marginal band, enclosing light spots at apex and 

 in middle. — ab. albifera Warr. Median area clear white, without any grey suffusion. Japan, Ussuri district, alhifera. 

 Korea and W. China. 



B. obliquaria Motsch. (20 g) differs from angulif&a in its stronger, more oblique antemedian line, con- obliquaria. 

 tinned on the hmdwing near the base and as a darkening of the abdomen, much smaller cell-dot of forewing, 

 lighter hindwmg and weakly marked underside, without the dark margmal band. Subterminal line bent 

 nearly as in repandata. Japan. In the forewing the 1st subcostal arises from the base of the 2nd and anasto- 

 moses with the costal; in angulifera it is free. 



B. grisea Btlr. (20 g) bears some superficial resemblance to the two preceding, but is somewhat grisea. 

 larger, rather more robust, the antennal pectinations very long. Both wings are smoky grey, the proximal 

 and distal areas tinged with red-brown, the principal lines rather strong and black, postraedian line nearer 

 to distal margin, especially on hindwing. — albifera ab. nov. has the median area white. Intermediates albifera. 

 also occur. Japan and Korea to Central China; ?Omeishan. Neuration of obliquaria. 



B. mavi sp. nov. (20 h). Not quite so long-winged as grisea, less robust, pectinations less long. Fore- mavi. 

 wing with discal dot smaller, post-median line less strongly bent outwards posteriorly, an almost black cloud 

 on the red-brown distal border. Hindwing with postmedian line much nearer to the cell-dot. Underside less 

 strongly irrorated than in grisea, both wmgs with distal area strongly darkened, hindwing with median and 

 postmedian Imes both rather distinct. As in grisea, the 1st subcostal of the forcAving is shortly stalked with 

 the 2nd and anastomoses shortly with the costal. Suiling, Shen-se, W. China. Type in the British Museum, 

 presented by Mr. Wilfred A. Maw. 



B. fortunata Blac\ier (= obscura B. Baker, hxichhi Kilian) (20 h) is a very distinct species. Face jortunata. 

 rather prominent, palpus strong, with projecting scales. Forewing not broad, distal margin less oblique than 

 usual, scaling dense and rough. Very variable, the large light blue-grey or whitish grey discal spot generally 

 characteristic. Underside smooth-scaled, somewhat smoky, both wings with dark discal spot (on forewing 

 large), thick curved postmedian line and dark border. The name-type is taken to include all the more variegated 

 forms. — wollastoni B. Baker is more unicolorous, grey. — fortunata inhabits the Canary Islands and Madeira, wollastoni. 



B. secundaria Esp. (20 h) somewhat recalls smaU, sharply niarked rhomboidaria, though the antennal secundaria. 

 pectinations are considerably longer. Among other differences may be mentioned the generally whiter ground- 

 colour, the more conspicuous whitish spot at middle of distal margin and the differently formed postmedian 

 line, which is less angularly broken anteriorly and curves outwards at the posterior margm. — ab. (gen. aest., 

 pr. p.) aterrima Hormuz. is a strongly darkened form, blackish brown, distally without white admixture, lines aterrima. 

 weak. Bukowina; ? Greece. — • Larva tapering anteriorly, red-brown, with dark dorsal lozenges and yellow 

 lateral spots. On Pinus sylvestris, hibernating. Pupa red-brown. Imago in pine- woods, July and August. Distri- 

 buted in Central and parts of S. Europe, wanting in the West. — fallentaria Stgr. is whitish-ashy or grey, not falleniaria. 

 brownish. Taurus. 



B. simpliciaria Leech (= lectonia Sivinh.) (20 h). I cannot understand how Leech can have descnhedsimpUcmria. 

 this as a variety of the preceding, except that the underside is similar. Besides being less sharply marked it 

 differs essentially in the postmedian line, which lacks the tooth on the 1st radial and the strong inward 

 curve in the posterior part. Japan. — faustinata Warr. (= praepicta Warr.) is a lighter violet grey or whitish fausUnata. 

 form with comparatively slight dark dustmg. W. China and as an aberration in Japan. ■ — Neuration as in 

 obliquaria (in secundaria it is as in angulifera). 



B. ribeata CI. (= abietaria Schiff.) (20 h) is distinguished structurally from the other European w&eate. 

 species by the absence of the fovea (genus Deileptenia Hbn., [Meyr. restr.]), but is also quite easj' to distinguish 

 by its shape and markings. The name-typical form is brown-grey with an olivaceous admixture, usually with 

 a characteristic row of fuscous spots proximally to the subterminal line. — ab. sericearia Curt, is glossy sericearia. 

 blackish, with the markings only weakly indicated. Extreme examples are absolutely unicolorous. England. 

 — Larva rugose, the tubercles placed on minute protuberances; grey-brown or ochreous brown, with pale 

 dorsal patches. On yew and other Coniferae, oak, birch, etc.; hibernating. Moth in July and August. Central 

 Europe; Russia; Japan.
