japonica. belong to a special form, which we call japonica form. nov. (45 b). The markmgs are somewhat less prominent, 

 tho black streak on the median vein is absent, likewise the light brown colouring, which is replaced by a band- 

 like light grey median area reachhig from first double line to the apex of the cell. 



sordida. F. sordida Wilenum. Forewing brownish grey with a slight reddish tint, the outer area of the forewing 



darker brown; prediscal band directed obliquely back-and outward, being black in its costal half and accom- 

 panied by 2 black dots at the costal margin; the postdiscal dentate band double, blackish, slightly incurved 

 below the middle; along the distal margin a dark line of arcs commencing at the costal margin with a prominent 

 black spot; at the outer half of the costal margin a row of black dots. Hindwing dark brown, the fringes paler. 

 — Japan (Hondo). 



nihonica. F. nihotiica Wileman. Thorax and forewuig whitish grey, irrorated with numerous black scales; 



besides the usual two transverse bands there is a rather prominent blackish subbasal dentate band; prediscal 

 band double, sharply defined and dentate, running obliquely back- and outward; the anterior half of the space 

 between it and the subbasal band darkened; postdiscal band likewise prominent, irregularly dentate, excurved 

 below the cell; between it and the apex a dark costal spot edged with black proximally and distally; along 

 the distal margin a line of blackish arcs; discal spot sharply defmed, black. Hindwing dark brown, with pale 

 fringes. — Japan (Hondo). 



concentrica. F. coticetitrica Oberth. (48 h). Somewhat resembling F. ocypete in the scheme of markings; ground- 



colour uniformly dark grey-brown, forewing without the yellowish longitudinal stripe, being slightly lighter 

 only below the cell; beyond the centre a sharply marked black semicircular transverse band upon which follows, 

 parallel with it, a whitish band, which does not quite reach the costal margin; beyond this band a row of black 

 vein-dots; before the black band an indistinct, deeply dentate, discal band composed of 2 blackish parallel 

 lines. Hindwing uniformly grey-brown. — Ta-tsien-lu. 



10. Genus: Hoplitii^ Hbn. (= Hybocampa Lerf.). 



Antennae pectinate to 2 3 in both sexes, very long in the (^ with the branches rather abruptly decreasing, 

 shorter m the $ with the branches gradually decreasing, the apical portion serrate. Palpi very short, scarcely 

 reaching beyond the frons. Proboscis vestigial. Eyes naked; ocelli absent. Forewing very elongate in (J, 

 nearly as in Exaereta, but the costal margin rather more strongly curved and the distal margin more evenly 

 and more strongly oblique; in $ the forewing essentially broader; vein 6 from centre of discocellulars, 6 together 

 with the stalk of 7, 8, 9 from the upper cell-angle, 10 free, areole absent. Hindwmg broad, rounded-triangu- 

 lar, veins 6 and 7 on a long stalk. Hair on thorax and abdomen smooth, on legs long, dense and woolly; hind 

 tibia only with end-spurs. — Larva almost naked, only clothed with very short, thin, but rather dense 

 hair, with 14 feet, the head large, flat, incised above and having a rounded-rectangular outline. 

 Thoracical segment 1 with 2 short obtuse lateral tubercles, abdominal segments 1^ — 6 each with a dorsal pro- 

 cess ending in a sharp point, which is directed anad, the anterior process of considerable length, with forked 

 tip, the following ones decreasing in size, on segment 8 a large vertical dorsal process with sharp point, as well 

 as 2 small lateral ones with the point directed backwards; the anal feet replaced by 2 very short points. Pupa 

 short and stout, the anal end broadly rounded, vertex with a short pointed tubercle which is employed in 

 opening the cocoon. The latter oval, flat, of the grey colouring of the tree-trunk to which it is fastened. — 

 Only 1 species is known of this genus. 



mUhauseri. H. milhauseri F. (= terrifica ScMff.) (45 a). Body grey-brown in S, paler grey in ?, patagia light 



grey with blackish dorsal edges. Forewing whitish grey, the distal half brownish, the veins being black for the 

 greater part, in the centre an irregular brownish yellow transverse band, which is especially distinct in 5; at 

 the hind margm 2 large blackish spots, of which the outer one is continued along the transverse band; a si- 

 milar spot before the middle of the costal margm. Hindwing brownish, whitish in the basal area, and blackish 

 in front of the anal angle. Distributed in Central and Southern Europe, but everyAvhere rare, not found in 

 England; Spain, Dalmatia, countries around the Black Sea, Amurland, West China and Japan. Also in 

 North Africa, where A. Seitz found the larva on cork-oak; this larva differs from European ones in the tips 

 umbrosa. of the processes being lemon-yellow instead of red. — In the East-Asiatic form, umbrosa Stgr. (45 a), the 

 whole outer half of the lorewing is strongly darkened to the costal margin. Japanese specimens also are dark- 

 er than European ones. — Egg pale brownish, with violet ring below pole. Larva pale yellowish green, mi- 

 nutely dotted with red, abdomuial segments 3 —7 with whitish red lateral markings and red tubercles. When 

 at rest the apex of the abdomen is held erect. June to August on Oak, also on Elm, Poplar and Birch. Pupa 

 dark brown. The flat cocoons, which are very difficult to perceive, are less hard than in Cerura and Di- 

 cranura ; the cocoons are only easily found if they bear a hole, which is said to be made by a woodpecker 

 having eaten the chrysalis; in many instances, however, the hole means simply the exit of the moth. The
