78 ACID ALIA. By L. B. Pkotjt. 



proximaria. A. proximaria Leech (5f) is agam considerably smaller than bimacularia and moorei, having only 



about the size of the largest ornata or subtilata. Hindwing shaped as in most moorei. Colour slightly more 

 reddish than in bimacularia, less dark-dusted than in moorei. Markings above as in moorei, only the postmedian 

 line of both wings more strongly incurved between the radials. Under surface more strongly marked than in 

 moorei, a distinct median line present on both wings in addition to the postmedian, usually also some dark 

 shading distally to the postmedian. It is not absolutely certain that this may not prove to be a small 

 eastern form of moorei, but the cj antennal fasciculation seems to be rather less thick. Central China : Ichang, 

 June and July. 



propin- A. propinquaria Leech (3 1, 5 f). Smaller than proximaria, the distal margin of the hindwing somewhat 



quana. crenulate, the tooth at the end of the third radial scarcely more pronounced than the others. Ground- 

 colour white, only slightly more brownish than in ornata. First and median lines light brown, indistinct, 

 angled near costal margin of forewing and more or less sinuous throughout; postmedian line light brown, 

 marked with fuscous spots at costal and posterior margins and with smaller dark dots on its teeth; distal 

 area of both wings mostly brown, traversed by a lunulate-dentate white subterminal line, which is strongly 

 widened proximally between the radials and on the submedian fold, usually forming triangular patches, 

 but occasionally so extended as to break the brown band into three separate patches; discal and terminal 

 dots black. Under surface with the postmedian line and the proximal half of the distal dark band present, 

 forewing dark suffused, sometimes showing the median line. ^J antenna with moderate ciliation; hindtarsus 

 about two-thirds as long as tibia. Appears to be distributed throughout China and in Korea. In the Pale- 

 arctic Region it flies in June and July, but at Hong-Kong it emerges as early as'the end of March. 



aequifas- A. aequifasciata Chr. (3 i) has the ground-colour clearer white than profinquaria, only a little less 



data. gQ t;iian ornata; the hindwing is a little narrower than that of the preceding species and is distinctly though 

 bluntly angled. The proximal and median lines of the forewing are in general even fainter, the postmedian, 

 which in propinquaria makes a proximal bend at the costal margin, is here parallel with the distal margin, 

 or even slightly bent distad in aequifasciata; the dark shading distally to the postmedian is more restricted 

 and more interrupted than is usual in proximaria, the distal margin itself (that is, beyond the white sub- 

 marginal line) mostly white. The hindwing differs still more materially from proximaria, the lines being 

 very weak and the distal dark shading obsolete. Under surface weakly marked, the postmedian line of the 

 forewing the most distinct, cj antenna with longish fascicles of cilia, hindtibia strongly dilated, tarsus perhaps 

 two-thirds of its length. I have ziot seen the $, but have no doubt that Staudinger has erred in placing 

 the species among Ptychopoda — perhaps on account of a superficial resemblance to Pt. trigeminata Haw., 

 with which Christoph compares it. The neuration is absolutely that of Acidalia. Only known from Amurland. 



satsumaria. A. satsuiTiaria Leech (5 e) is distinguished by its very small size, rather brownish wliite tone, strongly 



angulated postmedian line of the forewing, while that of the hindwing is comparatively regular, and by having 

 the posterior dark blotch in the distal area of the forewing more strongly developed than that between the radials. 

 The inner line of forewing and median line "of both wings are present, fine and brown, both are outcurved 

 anteriorly and incurved posteriorly on the forewing. Postmedian line of fore%ving angled distally on the 

 first radial, then running almost straight basewards, right-angled about the second radial, again bent (though 

 not quite so sharply) at the first median. The area distally to the postmedian irregularly suffused with brown, 

 the strongest brown blotch being between the radials and containing a few fuscous scales, while a blotch 

 near the hinder angle is almost wholly fuscous. Subterminal line similar to that of propinquaria, its ex- 

 pansions less extreme. Postmedian line of hindwing a little sinuous and subdentate, nearly parallel with 

 distal margin, followed distally by a rather thicker but rather paler brown line. Both wings with black 

 discal dot. Under surface extremely weakly marked, forewing slightly more brownish than hindwing. The 

 distal margin of the hindwing is very weakly angled in the middle. <$ antennal cilia rather long; tarsus about 

 two-thirds the length of tibia. Satsuma, May, only Leech's three specimens known to me. 



butleri. A. butleri nom. nov. (= insolata Btlr. nee Feld.) (7c), from Dharmsala, is closely related to the preceding, 



but I do not think it can be conspecific. The ground-colour is of a rather cleaner white, the markings 

 a rather greyer brown ; the postmedian line of the forewing reaches the posterior margin rather nearer to the 

 hind angle, that of the hindwing is placed rather nearer to the distal margin and the line which follows it is 

 better developed. Distal margin and fringe more distinctly marked with blackish than in satsumaria. The 

 forewing beneath shows a more distinct dark costal spot, marking the commencement of the postmedian 

 line. A. pedilata Feld., from Ceylon, to which Hampson has sunk insolata, is another allied, but distinct spe- 

 cies.
