3'74 BOARMIA. By L. B. Prout. 



eosaria. B. eosaria Walk. (= sinuosaria Leech) (21 c) is a handsome species, perhaps related to the two prece- 



ding but very distinct in the more violet-grey ground-colour, more red-brown markmgs and in having the 

 black lines more sinuous, thickened m places, especially at the hindmargm of the forewing. Chusan Islands to 

 Ningpo. 



dbacuraria. B. obscuraria Leech (21 e). Very distinct in the deep red-brown colouring and rather Hemerophila- 



like markings; the distal margin of the hmdwing is strongly crenulate as in that genus, but the wings are elon- 

 gate and the fovea developed. In some respects it somewhat recalls rimosa or phantomaria. Antenna rather 

 short, very strongly pectinate. W. China: Pu-tsu-fang. 



viertlii. B. viertlii Bohatsch is said to come between secundaria and n'&eaia.but according to Meyrick has the 



neuration of the section Boarmia. Antennal pectmations quite different from those of secundaria, tapering 

 towards thetr tips, median area of forewing considerably narrower, antemedian line more curved, postmedian 

 less so, distal area more regularly darkened, without the quadrate pale spot, behind the 3rd radial vein. From 

 manuelaria (25 g) it also differs in the tapering pectinations, the postmedian line of the hindwing is placed 

 further from the distal margin, the subterminal line shows no dark shadmg proximally. Larva in May, on oak. 

 Moth at the end of June and in July, only knoM'n from Hungary and Marasch (Taurus). 



approxinm- B. approximaria Leech (21 d) except in neuration resembles a large ribeata, but the antemedian line 



na. jg straighter, the postmedian of the forewing more oblique from its angle to the h'ndmargin and the underside, 

 as in the succeeding group, is weakly marked, only the cell-spots and postmedian line being present. W. China: 

 Ni-tou and Pu-tsu-fang. 



rdboraria. B. roboraria Schiff. (= consobrinaria Hhn. nee Blch.) (21 d). This species and its Asiatic forms or 



allies represent the largest Boarmia. It further differs from punctinalis in having the discal lunules blacker, 



not pale-centred, the lines more thickened and blackened at the hindmargin, the subterminal less deeply den- 



infuscata. tate, underside of forewing with a dark subapical mark which is wanting in punctinalis. — ab. infuscata Stgr. 



melaina. (21 d) is much darker, the upper surface densely dark-dusted throughout. — ab. melaina Schulze is a more 



extreme melanotic development, satiny black, with the underside also infuscated. ■ — Larva like a knotted 



oak-twig, the 2nd abdominal segment much swollen and bearmg a pair of dorsal protuberances, the 3rd with 



protuberances beneath, the 8th with a dorsal ridge; brown with lighter and darker mottlings, no very definite 



pattern. On oak, hibernatmg. Pupa stout, with strong sculpturuag, dark chestnut-brown. On the wing in 



June and July, found resting on tree-trunks by day, often visiting ,, sugar" late at night. Europe and Trans- 



isabellaria. caucasia. — is^abellaria Stgr., founded on 2 specimens (Urga and Kentei) is perhaps a mere aberration. Fus- 



arguia. cous irroration wanting, lines extremely distmct. — arguta Btlr. (= amiurensis Stgr.) (21 d) represents roboraria 



in S. E. Siberia and Japan. The ground-colour is appreciably darker, the black markings much stronger, a 



black spot distally to the postmedian of the forewing. Underside normal or with stronger postmedian line, 



sometimes with increased dark dusting and larger subapical cloud. Recorded as an aberration from the Kentei 



menetrieai. district. — menetriesi Stgr. (= kidsicola Gmbg.) is puzzling, perhaps a small, narrow- winged, weakly marked 



aberration of roboraria arguta, but said to have the cell-mark of the forewing pale-centred; underside almost 



unmarked except the discal lunules. Amurland: Kidsi, one only. 



lunifera. B. lunifera Btlr. (21 d). Closely related to roboraria, on an average still larger, ground-colour almost 



as strongly dusted as inab. infuscata but with more brown admixture, the lines strong, deeply lunulate-dentate, 

 their course somewhat different (very noticeable is the oblique posterior and of the postmedian of the forewing), 

 their thickening at the hindmargin not appreciable, the underside glossy violet -grey with darker submarginal 

 band, the forewing with white apical spot. Japan. 



invenusiaria. B. invenustada Leech (21 e). Differs from roboraria in having the discal marks pale-centred, lines less 



blackened at hmdmargin, the median obsolescent, postmedian much less bent, followed by a stronger brown 



suffusaria. shade (superficially recalling the subgenus Phthonosema), underside more dusted. — ab. suffusaria Warr. Uni- 



sinicaria. formly suffused with dull grey, obUteratmg the markings. — Japan and Amurland. — sinicaria Leech has 



the postmedian line sharper and blacker, subterminal better defined, more bent, cell-mark of hindwing black, 



rarely pale-centred. W. China. 



pundtinalis. B. putictitialis Scop. (= urticaria Hufn., griseonigra Goeze, bandevillaea Gsoff., consortaria F.) (21 e). 



This species, generally known by its youngest name, is variable in colour, but generally easy to recognize. 



Hindwing beneath with hairy clothing between 2nd submedian vem and fold, such as becomes highly developed 



consohrina- in the subgenus Serrada. The typical form is slightly more bro-niiish than that of roboraria. — ab. consobrinaria 



ria. Blch. is nearly uniform grey, with dark band before the subterminal line. — ab. humperti Humpert (21 e) is 



grisearia. unicolorous blackish, only the somewhat interrupted) subterminal Ime white. — grisearia Bartelis very small, very 



marginaia. uniform grey, feebly marked, the underside not black-dusted. Orenburg. — marginata Herz is also small, rather 



uniform grey-white, but with a dark border between the subterminal line and termen. Upper Amur and Korea.
