MICROPHALERA; NOTODONTA. By Dr. K. Grtoberg. 299 



H. pulcherrima Moore, a species from Southern Asia whose name-typical form has not yet been recorded 

 from Palearctie territory. — On the other hand, corticalis Butl. (45g) inhabits the southern Ussuri district and coriicalis. 

 Japan. It differs from pulcherrima, apart from its lesser size, in the paler colour of the body and the much 

 paler forewmg with much less prominent markings; only the blackish brown, distally pale-edged, submargmal 

 band and the black line beyond it are usually sharply expressed. In Japan occurs a second form of this species, 

 which we call stigmatica ab. nov. (45 g); the forewing is strongly darkened, the ground-colour being almost uni- stigmatica. 

 formly grey-brown, the dark-edged white discal spot being very prominent; also the submarginal line is less 

 well-developed as is usually the case in corticalis. 



20. Genus: Microplialera Butl. 



Antenna of (J serrate and plumose, tuft-like. Palpi scarcely extending beyond the hair of the frons, 

 densely hairy. Proboscis feebly developed. Eyes naked; ocelli absent. Thorax with a vestigial, short and 

 obtuse crest between the patagia; abdomen with a strong tuft of hair on the basal segment. Legs with long 

 and dense hair, hind tibia with long mid- and end-spurs. Forewing elongate, with pointed apex, distal margin 

 strongly oblique, little convex, hind angle sharply marked ; hmd margui slightly curved in proximal half, without 

 distinct tooth of scales ; veins 6 —9 stalked, the stalk thrown off from upper angle of cell, 10 anastomosing with 

 stalk of 7, 8, 9 and forming a long areole. Hmdwing broad, evenly rounded, vems 6 and 7 on a short stalk. 



M. atrovittata Brem,. (= insignis Butl, Notod. toddii Holl.) (45 f). Body and hindwing dark greyish atroviltaia. 

 brown, thorax with black transverse band. Forewing with a grey-brown ground, partly more greenish grey, 

 particularly at the costal and hind margins (rather too light in our figure); an intensely black longitudinal 

 streak below the cell from the base to the distal margin; pre- and postdiseal dentate black bands broken in 

 centre and only distinct anteriorly, the postdiseal one distally with pale edge; in the marginal area a black 

 streak between veins 4 and 5, at the margin wedge-shaped black spots on the veins. — Ussuri district and Japan, 



M. grisea Butl. Forewing white, light brownish in places, irrorated with black scales; in the median grisea. 

 area there are 4 blackish lines placed in pairs and commencing at the costal margin, the two central ones being 

 band-like, irregularly dentate, and approximated below the cell; in the cell a black longitudinal streak, beyond 

 the cell 4 similar streaks in zigzag; distal margm spotted with black. Hindwing dirty white, with a moderately 

 broad pale brown border. — Southern Ussuri district and Japan. 



M. alboaccentuata Oberth. (48 f). Ground-colour of wings dark grey-brown; forewing with a black aZ6o- 

 longitudinal streak in the cell and two sharply marked long black submarginal spots, which might be considered "^'^centuaia. 

 a submarginal band interrupted m the centre; a conspicuous, sharp, white angle-spot beyond the middle of the 

 hind margin close to the posterior submarginal spot; along the distal margin black internervular spots, at the 

 costal margua the beginning of a postdiseal dentate band, which terminates at the hind margin with the white 

 spot mentioned ; at the apex of the cell a black transverse bar with a narrow pale border. Hindwing uniformly 

 grey-brown. — Ta-tsien-lu. 



21. Genus: IWotodoiita 0. 



Antennae pectinated to the tip in the cj, the branches moderately long and strongly decreasing in length 

 in the apical tliird, in $ only serrate ; basal segment of (^ with a tuft of hair. Palpi short., not reachmg beyond 

 the hair of the frons. Proboscis vestigial. Eyes hairy; ocelli absent. Hair of body and tibial spurs as in Pheosia, 

 thorax without crest of scales. Forewing somewhat less elongate and broader than in Pheosia, the apex a little 

 more rounded, distal margm strongly oblique, forming an obtuse angle with the hind margin, the latter with 

 a strong tooth of scales; neuration as in Pheosia, no areole. Outline and venation of hindwing likewise as in 

 Pheosia.. ■ — Larvae smooth and almost without hair, with 16 feet; with the exception of N. anceps, whose larva 

 has no hump, they bear (as far as they are known) on segments 2 to 4 a process strongly directed backwards 

 and a more pyramidal one on abdominal segment 8. At rest they keep the head- and tail-ends raised, like 

 the larva of Stauropus; but .A^. anceps is an exception also m this respect. The caterpillars feed on deciduous 

 trees, pupating on or in the ground. Pupa rather stout, the tail-end with 2 points or rounded. 



The Palearctie fauna contains 22 species; 6 of them are found in Europe, all occurrmg also in Eastern 

 Asia, with the exception of N. tiefi, which so far is only known from the Ural. The species of Notodonta exhibit 

 a rather great variety in markmgs, but in most species, as in Drymonia, we find distmct pre- and postdiseal 

 dentate bands. 



N. drotnedarius L. (= zebra Don., perfusca Hau-.) (46 a, 56 d). Forewing pale brownish grey to dark drome- 

 grey-brown, with light-edged dark brown pre- and postdiseal dentate bands, the dark discal spot likewise pale- Darius.
