6G Transactions. — Zoology. 



One fine specimen, kindly presented to me by Dr. W. H. Gaze, who 

 informs me that he took it, with a second, at South Eakaia amongst rough 

 herbage in March. 



Fam. 3. CONCHYLIDJE. 



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. Heterocrossa, Meyr. 



Thorax smooth. Antennae 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, 3 and 4 stalked from posterior angle of cell, 5 from upper 

 angle of cell to slightly above apex, 6 free. 



Eemarkable 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. 



37. 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 ; antennas 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 disc at f 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 \ from base ; an angulated trans- 

 verse row of blackish dots from f 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.
