XV—THE 
CARPOSINA CRYODANA. 
(Heterocrossa cryodanda, Meyr., Trans. N.Z. Inst. xvii., 148.) 
(Plater ties 9) a) 
This species has occurred at Dunedin and Invereargill. 
The expansion of the wings is Slightly over 8 inch. The 
fore-wings are rather elongate, oblong, with the termen oblique, 
white, thickly speckled with pale brownish-grey; there is a short 
black streak from the base just beneath the costa and usually a 
thick, irregular, black longitudinal streak near the middle of the 
wing. The hind-wings are white slightly tinged with grey. 
The perfect insect appears from September till Novem- 
ber, and frequents Manuka serub (Leplospermum). My. 
Philpott informs me that it is very common in the neigh- 
bourhood of Invereargill. 
CARPOSINA EXOCHANA. 
(Heterocrossa exochand, Meyr., Trans. N.Z. Inst. xx., 76.) 
(Plates XXTV= flea) 
This very distinct species has occurred at. Masterton, 
Wellington, Nelson, Christchurch, Dunedin and Inverear- 
gill, 
The expansion of the wings is about one inch. The fore- 
wings are very elongate with the apex acute and the termen 
slightly curved and oblique, pale brownish-ochreous, slightly 
darker between the veins; there is a short brown mark on the 
costa near the base, several brownish-black spots near the mid- 
dle, enclosing a more or less cloudy patch, three distinct black 
dots on the costa before the apex and a sub-terminal series of 
cloudy black dots becoming obsolete towards the costa and dor- 
sum. The hind-wings are very pale ochreous. 
The perfect insect appears from September till May. 
It is usually taken at light, but is not a common species. 
As, however, it has a superficial resemblance to some of the 
common Crambi it is probably often overlooked by eol- 
lectors. 
CARPOSINA CHARAXIAS. 
(Heterocrossa charaxias, Meyr., Trans. N.Z. Inst., xxiii., 98.) 
(Plate XXII., fig. 20 9.) 
As yet this species has only been recorded from Well- 
ington. 
The expansion of the wings is slightly over 4 inch. The 
fore-wings are rather elongate, oblong, with the termen very 
oblique and slightly waved, white densely speckled with brownish- 
grey; a small black spot is situated on the costa near the base; 
a minute black dot on the dorsum near the base; seven small 
brown spots on the costa; a short oblique black bar in the disc 
before 4, parallel to the termen,; there are several scattered black 
dots or short marks preceding the tufts; an angulated series of 
sub-terminal dots obsolete at extremities and a series of very 
indistinct terminal dots. The hind-wings are white. The palpi 
are longer in the female than in the male. 
The perfect insect appears in November and may be 
found resting on the stems of manuka (Leptospermwm) in 
the Wellington Botanical Gardens, where it is sometimes 
very common. It is evidently closely allied to Carposina 
cryodana, though apparently quite distinct. 
TORTRICIDAE. 217 
CARPOSINA ERIPHYLLA. 
(Heterocrossa eriphylla, Meyr., Trans. N.Z. Inst., xx., 76.) 
(Plate XXIV., fig. 52°9; Plate 1., fiz. 19 larva.) 
This very large and handsome species has been taken 
at Ohakune, and is occasionally met with around Welling- 
ton. 
The expansion of the wings ranges from 1 to 1% inches. 
The fore-wings are elongate, slightly dilated towards the termen, 
which is straight and oblique; pale green with black markings, 
the spaces between the veins more or less speckled with white; 
a@ row of very conspicuous marks on the costa and termen; two 
small black marks near the base; a very large irregular mark 
at about 4; there is a conspicuous ring-shaped mark below the 
costa near the middle with an irregular branching line beneath 
it, the whole surrounded by a brownish shading; a very irregular 
series of sub-terminal dots is also present, and the veins are 
marked in darker green. The hind-wings are white. 
Varies considerably in the intensity of the green col- 
ouring, which, in bred specimens, inclines to yellowish- 
brown; in such forms the scaling between the veins is often 
whitish-ochreous. 
The larva burrows under the bark of Aristotelia race- 
mosa, usually selecting for this purpose the side burrows 
formed by the larva of Hepialus virescens, where it feeds 
on the sappy bark and wood of the living tree. It is full 
grown about the end of October, emergence taking place 
in December. 
Its length when full-grown is about’ # inch. Cylindrical, 
slightly tapering at each end with the segments deeply excised. 
The head is dark reddish-brown, the second segment with shin- 
ing brown dorsal plate; back of rest of segments bright pink, 
slightly tinged with purple; ventral surface pale whitish, slightly 
tinged with blue; there is a row of rather large horny warts 
around segments 2, 3 and 4; a double series of sub-dorsal warts 
on the other segments, except the last, and three lateral lines 
of such warts. The legs and prolegs are well developed. 
The pupa is enclosed in a cocoon composed of frass, 
joined together with silk. 
The perfect insect appears form September till April. 
It frequents forest but is by no means common. It is usu- 
ally found resting on tree-trunks where its colouring is 
highly protective amongst green lichens. The similar green 
and black coloration exhibited by Jzatha peroneanella 
(Plate XXV., fig. 54) is very interesting in this respect, as 
it clearly indicates how a highly specialized type of colour- 
ing, has been independently acquired for similar protective 
purposes, by two species which, in other respects, do not 
resemble each other. 
CARPOSINA GONOSEMANA. 
(Heterocrossa gonosemand, Meyr., Trans. N.Z. Inst. xv., 67; Proce. 
Linn. Soc. N.S.W. 1882, 179; epomiana, Meyr., Trans. N.Z. 
Inst. xvii., 149.) 
(Plate XXII., fig. 23 9.) 
This species has occurred at Wellington, Nelson, Otira 
River, Dunedin, Lake Wakatipu, Invercargill, Stewart 
Island and Auckland Island. It is probably common and 
generally distributed throughout the country.
