BOARMIA. By L. B. Prottt. 365 



Thorax hairy beneath. Femora glabrous or slightly hauy. Hindtibia in ,^ generally dilated, with hair- 

 pencil. Forewing nearly always with fovea; 1st — 2nd subcostal separate, stalked or coincident. Hindwing 

 with distal margin nearly always waved or crenulate. Larva generally twig-like, frequently with some humps 

 or protuberances. 



A very large and cosmopolitan genus or group of genera, very difficult to subdivide satisfactorily al- 

 though showing considerable variation in structure, chiefly in the secondary sexual characters of the ^. I have 

 indicated as separate sections a few of the groups which present the most noticeable differences in habitus, 

 and which have been regarded by some noticeable differences in habitus, and which have been regarded by 

 some systematists as genera; the typical section, with pectinate ^ antenna. I have separated (so far as they 

 are known to me) according to the neuration, the group Chora corresponding in part to Mbyricks Selidosema, 

 Boarmia to his Diastictis. 



A. Abdomen long, rather robust; $ with long ovipositor. Antenna of ^J 

 strongly pectinate. Wings rather narrow (Jankowskia Ob.). 



B. athleta 06. (= fuscaria Leech) (20 d). Easily recognized by its shape and coloration. Face rather «ttZeto. 

 flat, palpus short. Forewing with 1st and 2nd subcostals widely separate, discocellulars oblique inwards. Ober- 

 THtJEs figure of the underside does not show the usual (though variable) ochreous admixture at the costal margin 

 of the forewing, on which account Leech failed to recognize the species. Japan and across Palearctic China. 



B. Build very robust. Antenna of cj plumose, with longish apicalpart 

 simple. Forewing elongate. Neuration of Cleora [PhtJionosema Warr.). 



B. tetidinosaria Brem. (? Stgr.) (20 d). A large species, showing somewhat the coloration of Biston iendinosa- 

 superans Btlr. (24 a), yet so distinct that I cannot conceive how STAtrDiNGEE has confused the two if he reallj^' '^*"" 



knew both. Unfortunately he does not notice the antennal structure, tendirwsaria further differs in having 

 the antemedian not followed by brown costal spot, etc. Japan and Ussuri. 



B. serratilineafia Leech (20 e). Similar to tendinosaria but rather mor-e violet-grey, ground-colour sci-ratUinea- 

 pale but rather strongly irrorated, antemedian line not black, postmedian finely and regularly dentate, scar- ""' 



cely curved outwards at radials, followed by a conspicuous tawny band, which becomes more rust-coloured at 

 hindmargin. Underside more dusted than in tendinosaria, with a vague dark grey costal half-band or shade 

 between the postmedian and the distal margin. W. China: Mou-pin. — dubitans Herz (as swperans vur.) is dubitans. 

 clearly, according to the description and figure, a form of serratilinearia, if not even a synonym. Very slightly 

 broader-winged, the teeth in the postmedian line less marked, the antemedian of the forewing black in its 

 posterior half. Korea and once in Amurland. 



C. Build less robust. Antenna of ^ bipectinate. Forewing with 1st — 2nd sub- 

 costal separate or short-stalked (Cleora Curt. = Aids Hhn.). 



B. rimosa Btlr. (20 d) somewhat recalls tendinosaria in the scheme of markings, but is in shape and rimosa. 

 structure a normal Cleora and is further abundantly distinct in its much darker red-brown colour and finer, 

 rather widely separated lines. Japan. 



B. charon Btlr. (20 e) is an anomalous species. Fovea small and slight, antennal pectinations short, charon. 

 ending in tufts of cilia as in biittneri, colour and markings not altogether dissimilar to those of Nychiodes livi- 

 daria but with a well developed, on the forewing very strongly curved, median line, a dentate whitish sub- 

 terminal, the postmedian more dentate, etc. Japan and Central China (Chang Yang). 



B. solieraria Rhr. (25 c). I do not know the typical form and am not quite satisfied that harterti is soUeraria. 

 the same species. Whitish grey, antemedian line of forewing so oblique as to be almost parallel with costa, 

 obsolete anteriorly to the acute angle, postmedian somewhat sinuous; hindwing with 1 or 2 brown lines in 

 proximal part, which is not dark-strigulated ; subterminal line black-edged proxinially. Larva on juniper. 

 S. France and Spain. — harterti Bothsch. (=powelli Ob., as solieraria form) is much darker, more brown, harterti. 

 postmedian line of forewing very straight ; hindwing dark-strigulated from base to postmedian line ; subter- 

 minal not black-edged proximally. Algeria. 



B. powelli Ob. (as Calamodes) seems to me likely, according to the figures, to be nearly related to powelli. 

 solieraria. Larger, more brownish (yet less dark than harterti), subterminal line of fore- as well as of hindwing 

 above and beneath with a median line as dark as the postmedian though not reaching the costa but terminating 

 just proximally to the cell-spot. Algeria: S. Oran. Possibly nearer to bastelicaria (5^5 d). 



B. haroldi Ob. This and the following may also belong in this vicinity. Light brown with the distal haroldi. 

 marginal line finely black. Antemedian line curved near costa, not acutely angled, postmedian rather straight 

 from middle of hindmargin to near apex, then bent at right-angles ; subterminal broad, undulate. Hindwing 

 with the 2 dark lines nearly straight, approximated, the postm.edian placed very near the discal dot; a pale 

 subterminal on a somewhat darkened distal area. Underside very weakly marked, discal dots large and con- 

 spicuous. Larva brown, on juniper. Algeria. Variable in colour.
