202 MU. 11. M'LAC11LA.N on NEW-ZEALAND TillOHOl'XEUA. 



hairs on each side of the central deja-ession, and shorter ones on the 

 flattened surface of the posterior lobe ; metathorax slightly paler than 

 the mesothorax, small, hairless ; the anterior margin deeply notched, 

 the metasciitellum triangular; the breast is rather densely clothed 

 with grey hairs. 



Wings — anterior wings very long and narrow, the apical margin oblique, 

 whitish cinereous, with numerous fuscous irrorations ; the region of 

 the anastomosis, an oblique spot on the costa slightly before the 

 apex, and the apical margin also fuscous, the latter interrupted by a 

 conspicuous white spot above the anal angle, which colour there in- 

 vades the fringe, which is otherwise fuscous ; a pale yellowish-white 

 longitudinal streak on the middle of the disk, ending at the anasto- 

 mosis : these markings, as well as the cinereous ground-colour, are 

 all produced by the arrangement of the variously-coloured short hairy 

 clothing; the discoidal cell is long and closed, the cellula thyridii 

 very long and also closed (a probable transverse veinlet between the 

 lower branch of the ramus discoidalis and the ramus thyrifer is indi- 

 cated in the figure by a dotted line, as I am unable to clearly make it 

 out) ; ramus thyrifer simply furcate in the S > twice forked in the ? 

 (as in Leptocerus) : posterior wings subhyaline, rather thickly clothed 

 with short yellowish pubescence, especially towards the apex ; fringes 

 short, yellowish ; neuration darker. (Plate II. figs. 5 & 5a.) 



Legs whitish cinereous ; the anterior tibiae and all the tarsi fuscescent ; 

 all the coxa; dark fuscous ; the underside of the tarsi with numerous 

 short spines ; spurs fuscescent, rather short, but the inner one the 

 longer in all the pairs. 



Abdomen fuscous. In the <S the terminal dorsal segment has a circular 

 notch in the middle of its margin ; app. sup. forming two short and 

 broad, somewhat triangular ])lates, furnished with long hairs on the 

 margins and at the tip; app. inf. stout, scarcely pointed, directed 

 upwards, brown ; between them is the penis, which is short and 

 thickened, with an appearance of a spine-like tooth at its apex. In 

 the 5 are two superior valves, resembling the app. sup. of the c? ; 

 these are placed one on each side of a short oviduct ; beneath, the 

 last segment is shghtly concave and shining, (cf $.) (Plate II. 

 figs. 6b, c.)
