One fine specimen, kindly presented to me by Dr. W. H. Gaze, who 
informs me that he took it, with a second, at South Rakaia amongst rough 
herbage in March. 
Fam. 8. CONCHYLIDA. 
Lower median vein of hindwings without (rarely with) basal pectina- 
tion; vein 2 of forewings rising from posterior fourth of lower margin 
of cell. 
20. HxrrRocRossa, Meyr. 
Thorax smooth. Antenne in male with long fine cilia. Palpi moderate 
or long, second joint roughly haired above and towards apex beneath. 
Forewings with costa in male simple, surface with raised tufts of scales. 
Hindwings broader than forewings, lower median pectinated towards base. 
Forewings with 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings 
with 6 veins, 8 and 4 stalked from posterior angle of cell, 5 from upper 
angle of cell to slightly above apex, 6 free. 
Remarkable as being the only known genus of the family possessing the 
basal pectination of the median vein, probably an ancestral character. The 
group to which it belongs, characterized by the peculiar neuration of the 6- 
veined hindwings, is almost confined to Australia. 
87. Het. adreptella, Walk. 
(Gelechia adreptella, Walk., Brit. Mus. Cat., 654, (Paramorpha) Meyr., Proc. Linn. Soc. 
N.S.W., 1881, 698.) 
Minor, alis ant. griseo-ochreis, saturate griseo-sparsis, punctis plerisque, 
macula disci postica parva, serieque punctorum postica transversa nigris ; 
post. albidis. 
Male, female.—14-17 mm. Head and thorax grey, more or less irrorated 
with whitish; palpi in male moderate, in female very long, lower half dark 
: fuscous; antenne in male whitish-ochreous. Forewings very narrow, costa 
moderately arched, slightly bent before middle, hindmargin straight, very 
oblique; greyish-ochreous or grey, sometimes mixed with whitish, espe- 
cially towards base of costa, and more or less densely irrorated with 
blackish-grey ; costa with about seven small suffused blackish-grey spots ; 
a suffused blackish-grey spot in dise at 4 from base ; between this and base 
are about eight black dots in upper half of wing, irregularly arranged, 
tending to be followed by raised scales; a large raised tuft on the discal 
spot, and another on submedian fold at 4 from base; an angulated trans- 
verse row of blackish dots from 4 of costa to anal angle; a hindmarginal 
row of similar dots: cilia dark grey, with whitish points. Hindwings 
whitish, apex sometimes greyish ; cilia whitish. 
Narrower-winged than the following, with dark grey and ochreous 
colouring, and otherwise very distinct,
