Meyrick. — On New Zealand Micro-Lepidoptera. 133 



The number of New Zealand species of this interesting genus is now 

 thirteen. Since my remarks on the distribution of the genus, Snellen has 

 described from the Malay Archipelago a species which he considered refer- 

 able to it, under the name of Diptychophora ammnella ; but it is represented 

 as having strongly pectinated antennae, and is therefore doubtless generically 

 distinct ; probably Snellen was not at the time acquainted with the real 

 neuration of the genus. 



8. Orocrambus, n. g. 



Ocelli large. Forehead rounded. Antenna? moderate, in male filiform, 

 simple. Labial palpi rather long, straight, porrected, clothed with very long 

 rough hairs, attenuated to apex. Maxillary palpi long, broadly triangular, 

 terminally expanded with rough hairs. Thorax and coxa? clothed with 

 long fine hairs beneath. Forewings with vein 7 rising out of the stalk of 

 8 and 9. Hindwings much broader than forewings ; vein 8 free, approxi- 

 mated to 7 in middle. 



Closely allied to Crambus, from which it is essentially distinguished by 

 the free vein 8 of hindwings ; the neuration is otherwise identical. Other 

 less reliable points are the wholly simple antenna?, the peculiarly broad and 

 rough hairing of the palpi, and the hairy coxa? and under surface of thorax, 

 but this last character is shared by some mountain species of Crambus, as C. 

 catacaustus. 



The genus is confined to New Zealand ; I have only one species, but 

 from a note of Mr. A. Purdie's in the N.Z. Journal of Science it appears 

 probable that there is a second, darker and without the pale fascia. 

 20. Orocr. melampetrus, n. sp. 



Male, female. — 24-26 mm. Head, palpi, antenna?, thorax, abdomen, and 

 legs dark fuscous-grey ; head and palpi mixed with grey- whitish. Forewings 

 moderate, oblong, slightly dilated posteriorly, costa gently arched, apex 

 obtuse, hindmargin not oblique, rounded beneath ; fuscous, strewn with 

 dark grey, appearing dark fuscous-grey, with a slight bluish gloss ; a whitish 

 irroration forming a moderate nearly straight cloudy fascia (appearing grey- 

 whitish) from | of costa to f of inner margin, very slightly curved outwards : 

 cilia greyish-fuscous. Hindwings and cilia fuscous. 



Unusually stout in build, and of singular facies. 



Castle Hill and Mount Hutt, sitting on the bare shingle slopes (which it 

 imitates in colour) at an elevation of 4,000 to 5,000 feet, in January ; not 

 uncommon, but very active in flight, and difficult to capture from the nature 

 of the ground, which affords but insecure footing. 



9. Crambus, F. 



Ten additional species of this genus have been discovered since my 

 paper was written, principally in the mountain districts, At the same time
