preceded by an obscure whitish suffusion ; an irregular dentate suffused 

 white mark at apex ; an irregular white line along hindmargin, tending to 

 form a spot in middle, and two confluent spots below middle ; hind-mar- 

 ginal edge blackish : cilia greyish-ochreous, more whitish at anal angle, with 

 two suffused darker fuscous lines, and with a white spot above apex. Hind- 

 wings whitish-fuscous-grey, with a dark grey spot before middle, a narrow 

 irregular well-defined grey band close before hindmargin, and a sinuate 

 grey line closely preceding band ; an interrupted blackish-grey hind-mar- 

 ginal line ; cilia grey- whitish, with a grey line near base. 



Peculiar in facies, readily known by the two double white transverse 

 lines. 



Tolerably common at Clrristchurch on fences and old walls in January, 

 and I have also taken it at light ; occurs also at Dunedin. Mr. E. W. 

 Fereday informs me that the imago has the same habits as Dipt, elaina, 

 whence it is probable that the larva feeds in the same way. 



3. Scenoploca, n. g. 



Antenna? of male crenulate, ciliated. Labial palpi moderately long, 

 terminal joint slender, exposed, hairs of second joint produced beneath into 

 an obliquely projecting tuft. Wings in female much abbreviated, incapable 

 of flight. Forewings with 12 veins, 8 and 9 stalked. Hindwings with 8 

 veins, 4 and 5 from a point, 6 widely remote at origin from 7, 7 and 8 

 stalked, cell closed. 



This genus is nearly allied in venation and other respects to the two 

 preceding, but is distinguished from all by the abbreviated wings of the 

 female ; the palpi also afford a noticeable character, for the long projecting 

 hairs of the second joint, instead of being appressed to the terminal joint, 

 are sufficiently depressed to form a very distinct oblique tuft, but some 

 species of Thinasotia show traces, though less marked, of a similar structure. 

 The larva is of the normal type, and feeds on lichens. Only one species is 

 as yet known to me. 



1. Seen, petraula, n. sp. 



Male. — 16-J-20 mm. Head grey-whitish, forehead blackish. Palpi 

 blackish, apex of maxillary palpi, and of second and terminal joints of 

 labial palpi, grey-whitish. Antenna? dark fuscous. Thorax grey-whitish, 

 shoulders mixed with blackish, back wholly suffused with blackish. Abdo- 

 men ochreous-grey- whitish. Anterior and middle legs black, tarsi with a 

 white ring at base of first three joints, middle tibia? with a suffused whitish 

 median band; posterior tibia? grey towards base and at apex whitish, tarsi 

 ochreous-white with a dark grey band on each joint. Forewings triangular, 

 moderate or rather narrow, costa very slightly arched, somewhat more 

 before apex, apex rounded, hindmargin regularly rounded, oblique ; white,
