forming ill-defined patches in the disc and towards the apex; the 
sub-basal triangular marking is much more acute on the costa 
and wider on the dorsum than in H. festiva and there are oblique 
pale bars at the tornus and at the apex, but no straight subtei- 
minal band. All the pale markings are heavily mottled with 
deep orange-red. The hind-wings are brownish-grey. 
The perfect insect appears in January, and frequents 
sub-alpine serub. 
HARMOLOGA COLUMELLA. 
(Harmologa colwmellad, Meyr., Trans. N.Z. Inst., lvii., 699.) 
(Plate LII., fig. 4 @.) 
This species was discovered by Stella Hudson on 
Arthur’s Pass at an altitude of about 4,000 feet above sea- 
level. It has also occurred on Mount Arthur. 
The expansion of the wings is ? inch. The fore-wings are 
deep yellowish-brown, with speckled white markings, more or 
less outlined in darker brown; an obscure oblong mark on dor- 
sum near base; an irregular transverse band from + of costa to 
near middle of dorsum, narrower at each end; the terminal third 
of wing is more or less heavily sprinkled with white, with the 
exception of a large diffused triangular brown patch on costa 
near apex, and a very conspicuous elongate-oblong patch, stand- 
ing on tornus, and almost reaching the costal triangle; the cilia 
are brownish-ochreous, barred with darker brown. The hind- 
wings and cilia are brownish-ochreous, very faintly streaked with 
darker. 
The perfect insect appears in January and may be 
looked for on open mountain country, just above the limit 
of forest growth. 
HARMOLOGA RETICULARIS. 
(Harmologa reticularis, Philp., trans. N.Z. Inst., xlvii., 199.) 
(Plate XXVIL, fig. 8 @.) 
This bright-looking variegated species was discovered 
by Mr. Philpott on Longwood Range near Orepuki, at an 
altitude of about 2,700 feet above the sea-level. 
The expansion of the wings is eleven-sixteenths of an inch. 
The fore-wings, which are oblong with the termen slightly 
oblique, are irregularly striped and mottled with rich brownish- 
yellow, silvery-white and leaden-grey; the basal area is grey with 
several patches of brownish-yellow followed by an oblique, silvery- 
white transverse band; the central area has two broad oblique 
brownish-yellow bands and a faint silvery-white costal bar, the 
remaining portions being leaden-grey; this is followed by a 
leaden grey and Silvery transverse line; there are two oblique 
brownish-yellow bars from the costa to the termen separated by 
a silvery-grey line; the cilia are grey mixed with. brownish-yel- 
low. The hind-wings are leaden-grey. 
The perfect insect appears in December, and frequents 
high open country. 
HARMOLOGA TOROTERMA. 
(Harmologa toroterma, Huds., Ent. Mo. Mag., 1xi., 221.) 
(Plate LIL. fig. 23 @.) 
This very distinetly-marked species was discovered by 
Mr. C. E. Clarke, at Mount Ida, Central Otago. 
The expansion of the wings is almost 1 inch. The fore- 
wings are elongate-oblong, with the termen almost straight; pale 
brownish-ochreous, with numerous brown and yellowish-brown 
Q 
transverse strigulae; a faint suffused purplish-grey basal patch, 
its outer edge strongly angulated and partly outlined in blackish; 
another suffused triangular patch on costa before middle, having 
at its apex a cloudy reddish-brown discal spot; a very distinct 
fine wavy sub-terminal line, having beyond it a broad pale ter- 
minal band containing a row of brown dots; the cilia are pale 
brown with darker basal line. The hind-wings are pale ochreous, 
with several series of faint grey spots; the cilia are pale 
ochreous, 
The perfect insect appears in February. 
Described and figured from a specimen kindly sent to 
me by Mr. Clarke. 
Genus 13.—PHILOCRYPTICA, Meyr. 
Antennae in @ rather strongly ciliated. Palpi rather short, 
obliquely ascending, second joint with tolerably appressed scales. 
Thorax with strong double posterior crest. Fore-wings with veins 
7 and 8 separate, 7 to termen. Hind-wings without cubital pec- 
ten, 3 approximated at base to 4, 4 and 5 short-stalked, 6 and 7 
stalked. 
Includes one species. 
PHILOCRYPTICA POLYPODII. 
(Harmologa polypodii, Watt., N.Z. Journal of Science and 
Technology, iv., 257.) 
(Plate XLIX., fig. 33 9.) 
This very darkly-marked round-winged species was 
discovered by Mr. Morris N. Watt in the Botanical Gar- 
dens at Wellington. It has also occurred at Wanganui. 
The expansion of the wings is about 4 inch. The fore-wings 
are broad with the costa very strongly and evenly arched and the 
termen rounded; in female brownish-ochreous with dull blue, 
deep red, and yellow-brown markings; there is a broad horizon- 
tal dull blue band along the costa from the base'to nearly $ and 
a very large tornal blotch extending along the termen almost as 
far as the apex; a broad, very oblique deep red bar extends from 
the costa at about 3 to the termen below the apex where it joins 
the tornal blotch; there are several small yellow-brown marks on 
the dorsum, on the discal edges of the costal band and tornal 
blotch, and on the pale apical patch; the cilia are blackish. The 
hind-wings, which have the apex rounded, are deep brown. In 
the male the fore-wings are almost entirely overspread with dull 
bluish-black; the red costal bar is very much reduced and mar- 
gined with black, there are several other indistinct black mark- 
ings on the costa and in the dise, and a distinct pinkish-ochreous 
apical patch. 
The following particulars are taken from Mr. Watt’s 
observations* on the life history of this interesting species. 
The length of the full-grown larva is about $ inch; 
cylindrical; ground colour bright green, head and protho- 
racie shield dark grey-brown; skin transparent, disclosing 
a bright green alimentary canal and dorsal vessel. It mines 
the leaves of Cyclophorus serpens and, as the leaves are 
relatively small and the larva voracious, the mine, with its 
branch galleries, soon occupies the major portion of leaf 
and eauses it to wither, whereupon the larva forsakes the 
old leaf and enters a fresh one.
