the hind margin witli a small central projection on which is placed a broad tooth of scales, the outer half 

 very feebly incurved; veins 7, 8, 9, 10 stalked from anterior cell-angle, 6 a short distance below it, no areole. 

 Hindwing broad and evenly rounded, veins 6 and 7 on a short stalk. — Larva^e slender, smooth, without hairs 

 and tubercles, the body somewhat flattened. Pupa in a thin cocoon, armed with short points at the anal end. 



0. velitaris Hufn. (= austera ScJiiff., bifascia,ta Vill., bifascia Walk.) (45c). Thorax grey, with black- veiilaris. 

 l)rown transverse band, patagia edged with black-brown, abdomen pale brown. Forewing light grey-brown, 

 with a slight reddish \nolet tint, a sharply marked prediscal curved double band, postdiscal double band less 

 sharp, slightly dentate and filled in with white; at the apex a dark-edged light grey spot ; discal spot somewhat 

 lighter than the ground of the wdng. Hind^ving with a feebly marked narrow light median band. — Central Eu- 

 rope (not in England), sporadic and rare, southward to Central Italy, eastward to Galicia and Hungary, Bithynia 

 and Armenia. Egg semiglobular, whitish. Larva glossy yellowish green, with 4 yellow dorsal longitudinal 

 lines composed of spots, and a broad, white, above brightly red-margined lateral stripe on a level with the 

 stigmata, which have blackish borders. July — September. On Oak and Poplar, especially on the lowest leaves 

 of low bushes. Pupa red-brown, in a loose web in the ground. 



0. melagona Borkh. (?= obliterata Esp., deleta Brahm) (45 c). Similar to 0. velitaria, the forewing melagona. 

 \\hitisli grey in the basal and distal marginal areas, the postdiscal band more strongly dentate, the discal spot 

 whitish, before the apex a dark triangular costal spot. — Central Europe; the northern boundary runs from 

 Belgium through Central Germany and Austria to the Bukovina; a sporadic species. Larva similar to that of 

 velitaris, glossy green, with 4 yellowish white dorsal lines and a white side-stripe which edged with red above. 

 Juty — September, on the lower branches of Oak and Beech. Pupa dark bro\\Ti. Moth in June — -July and 

 August — September, but the second brood does not occur regularly. 



0. ussuriensis Piing. (49b) is a recently discovered form which is provisionally placed here; the msuriensis. 

 description kindly sent us by Herr PIingeler is printed below *). 



0. japonica Wilenmn. Head and collar blackish, thorax grey, with blackish intermixture. Forewing iaponica. 

 brownish grey, with dark brown suffusion and yellowish browia ba,se,'near which are some diffuse blackish 

 subbasal spots; the double prediscal band black, the postdiscal band white edged with black at both sides; 

 before the apex a dark costal spot which encloses 2 smaller black spots; discal spot indistinct. Hindwing dark 

 greyish brown, with diffuse paler median line. — ■ Japan. 



27. Genus: Odoiitoi^ia Hbn. 



Antenna of (^ wdth reiher long pectinations, or only serrate with long dense cilia, in the 9 simple, seti- 

 form. Palpi very short. Proboscis vestigial. Eyes naked, ocelli absent. Thorax with dense woolly hair and 

 scales. Legs with long wool. Abdomen more short-hairy. Hind tibia ^vith mid- and end-spurs. Forewing thinly 

 scaled, broad, with almost straight costal margin, pointed apex, rather strongly oblique dentate outer margin, 

 which projects a little more at vein 4; hind margin with a strong tooth of scales before the middle; veins 6, 

 7, 8, 9 stalked together from the upper cell-angle, 10 anastomosing with stalk of 7, 8, 9 in a point and form- 

 ing a rather large areole. Hindwing broad, the distal margin likewise dentate and forming a distinct angle 

 with the abdominal margin ; veins 6 and 7 on a very long stalk. — ■ Larva slender, with sparse dispersed hair, 

 16 feet, without tubercles, only abdominal segment 8 bearing a very low dome-shaped swelling. Pupa in a 

 loose cocoon in the ground, stout, v^dth obtuse anal end. 



0. carmelita Esj). (= capucina Hbn.) (46 g). Antenna of ^ only dentate and ciliate. Thorax dark carmelita. 

 brown, with the hind margin of the patagia grey. Abdomen light brown. Fore^^^ng dark brown u-ith a reddish 

 tone, the anterior half darkest, the j^osterior and outer areas strongly suffused with whitish grey; tooth of scales 

 at hind margin black-brown ; costal margin at one-third and again at two-thirds with a white spot as indication 

 of vestigial transverse bands, the proximal spot small and often diffuse; of the transverse band usually only 



*) 0. ussuriensis Piing. Expanse, <J 36 mm, length of forewing 16 mm; ? larger. Somewhat smaller than melagona 

 Borkh., similar in build, hut without tooth of scales; ground-colour of forewing pvirer and more glossy grey, basal area much 

 narrower, bounded by a scarcely dentate black lino, median area washed with grey-brown, especially in its anterior portion 

 as far as the long, hmiform, black cell-.>:itreak : outer median line doulile, very obsolescent, costal subapical spot similar to 

 that of melagona, grey-brown with 2 black transverse bars, marginal line composed of flat black lialfmoons. Hmdwing lighter 

 grey, in the ? with the marginal area slightly tlarkened. Underside of forewing purer grey, that of liindwing much ligliter, 

 particularly in the o, whitish with tlie arcuate Imc more distal. Thorax light grey, with dark jjosterior border, prothorax 

 and patagia with dark edges. Antenna of o similar to that of melagona, but the apical portion naked, ^-antenna with shorter 

 pectinations, otherwise as in cJ, very different from the shortly serrate antenna of melagona $. We place the species only pro- 

 visionally into Uclirosiignia. — Vssuri district, an apparently bred pah' from il. Kokb. R. PiJxGELEK.
