MeyrioiL — On New Zealand Micro-Lepidoptera. 123 



This group, usually separated as a main division, offers in my opinion 

 no characters sufficient to admit of its separation from the Pyralidina, with 

 the other families of which it is closely allied. The wings are unusually 

 narrow, and the abdomen and legs very long and slender. 



Oxyptilus vie/ens, Felcl., said (perhaps erroneously) to be from New 

 Zealand, I have not been able absolutely to identify. Felder would 

 probably (loose as he is) have hardly classed it as an Oxyptilus unless he 

 had observed the characteristic tuft on the third plume of the hindwings. 



The four genera may be thus tabulated : — 



la. No veins to costa from cell of forewings . . . . . . 2. Aciptilia. 



lb. Two or more veins to costa from cell. 



2a. Face smooth . . ... . . . . . . . . . . . . 3. Lioptilus. 



2b. „ with a cone of scales. 



3a. Hindwings 5-veined . . . . . . . . . . . . . . 4. Mimceseoptilus. 



3b. ,, 6-veined . . . . . . . . . . . . . . 5. Platyptilia. 



2. Aciptilia, Hb. 

 Face smooth. Antennae moderately ciliated. Palpi moderate or short, 

 very slender, ascending. Posterior tibiae with spurs very long, inner longer 

 than outer. Forewings cleft more than -J, segments linear-acute ; with 6 

 veins (3, 3); 2 and 3 from a point, 4 from transverse vein, 5 to apex, 6 free. 

 Hindwings with segments linear-acute, third dilated anteriorly ; with 5 

 veins (1, 2, 2) ; lb. distinct, 2 and 3 from a point (rarely 2 obsolete), 4 

 apparently coalescing wholly with 5 beyond ceil. 



Stands isolated by the entire obsolescence of all the veins usually rising 

 from the cell before the upper angle, and marks a terminal development in 

 this direction. Apparently of world-wide distribution, though from Australia 

 I have only a single species, 

 la. Hindwings dark grey . . . . . . . . . . . . . . 5. innotatalis. 



lb. ,, white. 



*2a. Forewings with a fuscous longitudinal stripe. 



3a. Thorax mostly fuscous . . . . . . . . . . . . 2. furcatalis. 



3b. ,, wholly white .. .. .. .. .. ..3. lycosema. 



2b. Forewings without fuscous stripe . . . . . . . . . . 4. monospilalis. 



2. Acipt. furcatalis, Walk. 

 (Aciptilus furcatalis, Walk., 950 ; Feld., Eeis. Nov., pi. cxl., 52.) 

 Male, female. — 16-19 mm. Head, palpi, antennas, and legs white ; 

 anterior legs internally dark fuscous. Thorax pale fuscous irrorated with 

 dark fuscous, anterior margin broadly white. Abdomen white, with a 

 central longitudinal fuscous stripe. Forewings light fuscous irrorated with 

 dark fuscous ; a broad costal streak from base to opposite cleft, an oblong 

 spot on costa beyond f , and a narrow line along upper edge of second 

 segment snow-white ; cilia white, costal cilia dark fuscous except on white
