3. BOLETOBIDiE. 



Forewings with areole simple, 11 separate, 12 free. Hindwings with 8 

 veins, 6 and 7 separate, 8 free, approximated to 7 towards base. 



A very small family, probably approaching extinction, inhabiting moun- 

 tains in Europe and probably other restricted localities. 



26. Cacopsodos, Butl. 



Face smooth. Palpi long, straight, porrected, roughly scaled above and 

 beneath. Antennse in male pectinated on inner side only. Forewings with 

 vein 6 from a point with 9, 7 from angle of areole, 10 anastomosing mode- 

 rately with 9, 11 separate, approximated to 10 in middle, 12 free. Hind- 

 wings with veins 6 and 7 separate, 8 free, closely approximated to 7 from 

 base to near transverse. 



I have not seen the male; if Butler's description of the antenna is 

 correct, it is the only New Zealand genus with uniserial pectinations. 



70. Cac. niger, Butl. 

 {Cacopsodos niger, Butl., Proc. Zool. Soc. Lond., 1877, 395, pi. xliii., 4.) 



Female. — 13 mm. Forewings rather narrow, costa sinuate, hindmargin 

 sinuate ; white, slightly mixed with grey ; inner margin narrowly grey ; 

 a slender black fascia almost at base ; a slender black fascia at ^, dentate 

 inwards above middle, dilated on costa ; a slender black fascia beyond 

 middle, sharply angulated in middle, dilated on costa, connected below 

 middle with preceding fascia by a suffused bar ; close beyond this a rather 

 broad parallel grey fascia ; an indistinct grey subterminal line. Hindwings 

 moderate, hindmargin rounded ; dark grey. 



Butler described his species from a single male, which was very much 

 darker than this, almost wholly suffused with dark grey, but I have no 

 doubt of the identity of the species, which probably varies a good 

 deal. 



I took a single specimen near Lake Wakatipu in December, at about 

 1,500 feet. 



4. LYECEID^l. 



Forewings with areole double, 11 anastomosing with 10, 12 anastomos- 

 ing with 11. Hindwings with 8 veins, 6 and 7 separate, 8 free, not ap- 

 proximated to 7. 



I have been obliged to form this family for the single included genus, 

 which is allied to the Emiomidce, but differs essentially from them. It is of 

 a decidedly primitive type, and approaches in the hindwings nearly to the 

 ancestral form of the group. 



27. Lykcea, Walk. 



Face smooth. Palpi rather short, slender, arched, appressed to face. 

 Antennae in male filiform, simple. Forewings with vein 6 from below 9,
