Pnhl. 25.111. WU. LOBOPHORA; MYSTICOPTERA. By L. B. Prout. 185 



N. misera i?<^r. (11 c). Nearly related to terranea but slill darker. At the same lime the ground-colour is misera. 

 much more mixed with brown, which shows up especially in the paler areas that precede and follow the 

 central band; the band itself has its proximal edge rather strongly incurved, though not so strongly as in 

 polycommata, and is of a dull blackish brown colour, apparently never reddish, rarely with conspicuously lighter 

 patches in its middle; distal area in general more strongly marked than in terranea, at least with a distinct lunulate- 

 dentate dark line following the outer pale band. Hindwing small, strongly darkened. Japan (Yokohama, etc.). 



N. rivularia Leech (12 a). Very distinct in coloration, etc. and probably forming a separate genus, in rivularia. 

 any case not a Cryptoloha, as described by Leech. Except in the more hairy palpus (which is of moderate 

 length) it agrees with Nothopteri/x as here characterized. Recognizable at once by the black and white wings. 

 W. China: Oniei-shan, Ni-tou, Che-tou, Pu-tsu-fong, flying in June and July. 



26. Genus: LiObophora Curt. 



Face smooth. Palpus short, rough-scaled. Antenna in both sexes simple. Hindtibia with 4 spurs, 

 the inner of each pair in the cf long and slender; cT with hair-pencil. Forewing with areole double. Hindwing 

 with discocellulars not biangulate, 2"'' radial from the centre, costal anastomosing with cell to considerably 

 beyond middle, 2"'* subcostal in cf separate, in ? shortly stalked; cf with a large lobe, reaching fully half the 

 length of the wing, 2""^ median very short and weak, running to the inner margin, submedian wanting. 



A quite distinct genus, differing from Nothopteryx in the 4-spui*red hindtibia, anastomosis of costal 

 vein and much more strongly developed lobe of cf hindwing. Only two or three species are known, inhabiting 

 Europe, Siberia and North America. 



L. halterata Hufn. {■= hexapterata Schiff. = ? inequaliata Pack.) (6f). Forewing whitish, with a very halterata. 

 slight tinge of brown, at least in the central area; a narrow subbasal dark band, closely followed by conspicuous 

 broader one, the pale line which separates them angulated anteriorly; the lines of the median area ill-defined, 

 dentate. Hindwing white, nearly always with a narrow greyer distal border and sometimes with one or two 

 indistinct lines in outer half. Forewing beneath very weakly but more uniformly marked; hindwing with very 

 distinct discal dot. Variable in the intensity of the markings. — ab. rudolphii Lampa has the forewing much rudolpML 

 darker than in the type form, the median area little lighter than the rest. — ab. zonata Thnhg.^) (6g) has the zonula. 

 lines of the median area almost entirely obliterated, the dark markings in the proximal and distal areas on the 

 contrary intensified. — Larva moderately stout, pale green, subdorsal lines pale yellow, conspicuous, other lines 

 faint or wanting; anal extremity with two small points projecting backwards. On poplars, particularly Populus 

 tremula, in June and July. Pupa short, very obtuse in front, taperingly rapidly behind, copiously sculptured, 

 wings glossy, yet densely covered with short lines, cremastral spike long, bifid, strongly hooked at the tip; 

 dark red-brown, segment-incisions paler. In a compact cocoon of silk and earth. The moth appears early in 

 May and may be found by day sitting on aspen trunks. It is widely distributed in Central and Northern 

 Europe and Siberia and a few localities in Southern Europe. 



27. Genus: Mysticoptera Meyr. 



Like Lobophora in leg-structure and in the strongly developed lobe of the cf hindwing, but differing 

 in the less smooth face, longer palpus, single areole, separation of the costal vein of the hindwing from the 

 cell in the cf and other characters. The discocellulars of the hindwing are biangulate, the 2"'' radial arising 

 below the middle; the wing-lobe is fringed with long hair towards the inner margin; the 2""^ median vein, as 

 well as the submedian, is wanting in the cf. 



Only one species is known. 



M. sexalata Retz. (= sexalisata Hbn. = hexaptera Latr.) (8 a). Generally not variable, but I have bred sexalaia. 

 one ? in which the median area is considerably broadened and scarcely darkened, but shows rather distinct 

 trasverse lines — recalling the arrangement in halterata. Larva moderate, nearly cylindrical, rather rugose, 

 head rather narrower, anal points well developed; green with whitish dorsal and subdorsal lines, tips of anal 

 points pink. Feeds in August and September on sallow, generally at a good height from the ground. Pupa 

 very thick ; wings smooth and glossy, greenish ; dorsal region and abdomen dark chestnut, covered with minute 

 punctures; cremastral spike strong, forked and hooked at the tip. Hibernates, the moth appearing about June; 

 it is said to be partially double-brooded, but I have no experience of this. Central and Northern Europe and 

 S. E. Russia. 



') Several recent authors, misled by an error of Stichel's, have quoted Sebaldt and others as the authors of 

 Thunberg's species. The system under which the Swedish university professors worked was very unsahsfactory, but the 

 true authorship is well understood in Sweden. See Journ. Botany vol. 51, p. 101.
