X. infantaria Guen. (= plumbea Philpott) (25 c). Closely similar to L. cinerearia and with nearly the infuniuria. 
same antennal structure; easily separated by the venation; further, the clear grey ground-colour lacks alto¬ 
gether the brownish suffusion, except that a faint indication of such is occasionally observable on a narrow 
subterminal band. Queenstown, November to early in January. Also common in January on Mount Cook. 
Gttenee’s type, not exactly localized, which has been assumed to belong to L. cinerearia , is really a small, 
somewhat faded $ of the present species. 
X. (?) suppressaria Walk. (25c). Founded on 2 $$ from Auckland, the type in good condition except suppressa- 
tliat it (as also the paratype) has lost its abdomen. I feel pretty confident that it is misplaced and should be 
a Euphyia or Horisme, closely related to the Australian E. severata Guen., with which it agrees in palpus, venation, 
etc. I suppose it is distinguishable from that variable species, and not an accidental introduction into New 
Zealand; the distal margins seem somewhat more crenulate and the oblique ochraceous-buff streak is broader 
and clearer, the underside rather darker. 
X. venipunctata Walk. ( = psamathodes Meyr., lucidata Huds., nec Walk.) (25 c). Unmistakable on venipuncta- 
account of the almost straight termen and markings of the forewing; postmedian edged with white dots on ia - 
the veins. Palpus and pectinations long. Widely distributed in New Zealand, including Stewart Island; also 
on the Chatham Islands. 
X. lucidata Walk. (= robustaria Walk., practica Meyr.) (25 c). Much more variegated, generally in the lucidata. 
with a good deal of white in the distal area (Walker’s type of robustaria shows this); postmedian line 
of forewing sinuate. New Zealand, the Walker types (as usual) without exact location; practica was 
described from the Motueka Valley, near Nelson. Distributed but rare, Auckland to Dunedin. — ab. plurimata plurimata. 
Walk, is a $ form with the median area strongly blackened. 
X. cinnabari Howes (= cinnabaris Meyr.) (25 c!) is a pretty, yellow species, evidently an intruder be- cinnabari. 
tween lucidata and its near ally rosearia, but I have conserved as nearly as possible Meyrick's sequence. The 
type has on the forewing a strongly darkened median band, but the commoner forms retain here more nearly 
the ground-colour, except on the dark bordering lines; in either case the area is edged on each side with white. 
Only in ab. obsoleta nov. do the dark and the white lines become practically obsolete, leaving only very obsoleta. 
shadowy traces of a median band. Garvie Mountains; the type of both forms are from Nevis, in my col¬ 
lection. The underside is in all cinnabari very weakly marked. 
X. rosearia Dbld. ( = ardularia Guen., inamoenaria Guen.) (25 d). Variable, but readily distinguishable rosearia. 
from lucidata on the upperside by the strongly curved proximal edge of the median band; the band itself is 
less strongly developed, sometimes very little darkened, commonly only darkened about its 2 or 3 proximal 
and 3 distal lines. When freshly emerged, both sexes are brighter, the <$ more rosy-tinged, the $ yellow-green 
rather than yellow. Palpus somewhat over twice diameter of eye; pectinations rather long. Widely distributed 
and common in New Zealand. Larva light green, with indistinct longitudinal whitish lines, the head greenish- 
yellow. Feeds on watercress. Pupa very dark brownish-black, glossy, spun-up among debris on the surface 
of the ground. 
S. subductata Walk. (25 d) is separated by Meyrick from rosearia, on 1 $ from Auckland, with no subductata. 
comparative description; perhaps he relied on the only “slightly” curved antemedian and possibly the “yellow- 
greenish" tone, his rosearia $$ being discoloured to ochreous or yellowish. I figure the original, which is also 
an Auckland $; it will be seen that it has quite the normal antemedian of rosearia , but only measures 23 mm 
(Meyrick’s $ 26 mm); its underside has just the same reddish tinge as in all rosearia. Hudson says it has 
occurred also at Kaeo and “appears to be confined to the extreme north of the North Island”, but strongly 
(and very justifiably) doubts its validity as a species; he figures as subductata a pale ochreous brown <j>, certainly 
not like the original (!). 
X. homalocyma Meyr. (= rosearia part., Meyr. olim, nec Dbld.) (25 d), from the Chatham Islands, homalocyma. 
expands 22 to 28 mm, the $ generally the larger, antennal pectinations long. “Somewhat intermediate between 
rosearia and subductata; markings much as in subductata, but forewing without the characteristic yellow-greenish 
mixture”, distal edge of median band much less prominent in middle. “It also approaches the larger Tasmanian 
centroneura, which however is reddish-tinged and has distinct band of median striae on hindwing”, etc. Hind¬ 
wing here very weakly marked. Founded on 27 specimens. 
X. oropliylloides Huds. (= orophyloides Meyr.) (25 d). “Very closely allied to orophyla [ Larentia\ and orophylloi- 
rosearia but with narrower wings”; forewing pale bluish grey, median band generally paler and browner than 
the rest of the wing; hindwing pale grey. Auckland Island and Campbell Island; generic position uncertain (the 
species unknown to me).
