with almost the colouring of austrina, scarcely a suspicion of yellowish remaining on either surface, therefore 
requires a name, as at first sight it looks like a separate species; markings, however, typical. Type $ from 
Hector, in my collection. 
D. enysii Bull. (24 b). The type $, collected with 2 others by J. D. Enys at altitudes of 3000—5000 enysii. 
feet (“New Zealand’’, locality not recorded), has the forewing closely like that of anceps, its costa perhaps 
still more shouldered at the base, its postmedian without the projection at 1st. radial; its hindwing much 
brighter orange, much more weakly marked, on the underside less weakly than above, apparently with its 
(very slender) postmeclian rather more strongly angled. The Tring Museum has one from the Urey mouth 
district. Probably, as has always been assumed, merely an extreme aberration of the species subsequently 
named — homomorpha Meyr. This is said to be “readily identified by the postmedian line of the hindwing’’, homomor- 
which is here angulated, remote in middle from median” (in anceps “curved, parallel to median”). The signi¬ 
ficant detail given regarding the hindwing is: “bright orange; basal space up to 1st. line mixed with dark 
fuscous; a second, more obscure line beyond and parallel to this, a third irregularly angulated and subdentate 
beyond middle, a narrow irregular interrupted subterminal fascia. Mount Hutt, 4 specimens, rather small 
(28 mm). Since recorded from Nelson. 
D. partheniata Guen. (24 c). A rather common New Zealand species, the hindwing predominantly partheniata. 
bright orange, the ground-colour of the forewing also more or less orange, its base and median area almost 
wholly darkened, or with some orange persisting in the central part, particularly around the cell-spot, occa¬ 
sionally invading almost the entire central area except its bordering lines. Hindwing beneath a little paler, 
its markings cut by pale longitudinal streaks. The larva feeds on Aciphylla squarrosa and is in certain attitudes 
well protected; light-brown, variable and sometimes tinged with grey-green; an ochreous subdorsal line, a 
dark-brown and a creamy-yellow lateral one. — catadees form. (? sp.) nov. (24 a). A remarkable specimen catadees. 
in the Tring Museum, unfortunately the only one known to me from Mount Peel, has the areole simple on 
the right forewing, double — though with the distal very small (2nd. subcostal stalked) — on the left, the 
orange parts paler, almost white, the outer band very slender, on the hindwing curving more slightly; under¬ 
side also whitish, the presubterminal dark band of the forewing broadened from 2nd. subcostal to 3rd. radial 
and again at the medians. 
D. fulminea Philpott (24 a). “24 mm.” According to its author nearest to callicrena but with the lines fulminea. 
different and the fringe unicolorous orange; callicrena , however, is a Dasysternica by venation. The unique 
type (a $ which has last its antennae) was captured on Bold Peak (head of Lake Wakatipu) in February. 
Lines yellowish, not white, the antemedian with a striking inward angle behind the cell. 
D. (?) strategica Mey r. (24 c). “35 mm.” We copy Hudson’s figure of the unique type; it only deviates strategica. 
slightly from Meyrick’s description in that the antemedian should be “somewhat irregular, slightly curved” 
and the yellowish median shade “well defined”. Hindwing beneath suffused with golden-yellow; markings as 
above. Lake Guyon, South Island; hardly an extraordinary aberration of Dasysternica callicrena with straighter 
proximal lines? 
D. transaureus Howes (= transaurea Meyr.) (24 a). A pretty little species, easily distinguished by transaureus. 
the (often broad) longitudinal interruption of the median area, the end of the median vein and the space 
about its branches here being yellow like the ground-colour. New Zealand: Garvie and Humboldt Mountains, 
also Flagstaff Hill (Dunedin) and Mount Cook; type from Nevis. 
D. micropolis Meyr. (24 b). According to Meyrick this has been confused with leucobathra but differs micropolis. 
in its small size, different underside and absence of yellow on the abdomen; subterminal line macular or sub- 
obsolete; fringe white, barred with grey. LTnderside with the white extended, especially on the hindwing 
distally. Arthur’s Pass, 5000 feet. 
D. leucobathra Meyr. (24 c). Larger (21— 25 mm). The underside affords an easy distinction from leucobathra. 
micropolis: forewing dark grey, with veins, a costal band and 2 incomplete lines (presubterminal and terminal) 
yellow, the other lines white; hindwing blackish, with similar scheme, the veins and longitudinal 
streaks (on subcostal, median and hindmargin) yellow. Distinct from the mechanitis group of Notoreas in 
the fringes, which are chequered with white at the base instead of having the basal part wholly dark. Otira 
River (type), Lake Wakatipu, Hunter Mountains. Arthur’s Pass and Mount Arthur tableland, i. e. up to 
4500 feet. 
D. pluviata Huds. (24 c) is compared with fulminea , but has the lines more slender, quite differently pluviata. 
formed (especially the antemedian) and perhaps whiter. If' the (very short) $ pectinations have been over¬ 
looked it will be a Notoreas near chioneres (24f) but blacker, the lines finer and whiter, the median faint (on 
hindwing wanting), the postmedian slightly incurved anteriorly, then almost direct (not angled outward),
