318 Mr. E. Meyrick on the classification 



discal spot ; a faint irregular dentate pale posterior line ; cilia 

 ochreous-wliitisli, with an interrupted dark fiiscous line. 



A very dull-looking species. 



Hamilton, New Zealand ; five specimens (one male, 

 four females) taken in a house, presumably attracted by 

 light, in January. 



Semioceros, n. g. 



Forehead flat, vertical. Ocelli present. Tongue well developed. 

 Antennae three-fourths of fore wings, in male stout, subdentate or 

 serrate, evenly ciliated (^) (murcalis) or with tufts of cilia (IJ), 

 rough-scaled above, bent before middle (not in ampliicedalis), 

 sharply bent beyond middle, with a tuft of scales on back above 

 bend. Labial palpi moderate, porrected or ascending, 2nd joint 

 with short dense projecting scales beneath, terminal joint short, 

 stout, obtuse, exposed. Maxillary j)alpi short, slender, filiform. 

 Posterior tibiae with outer middle-spurs one-third, outer end-spurs 

 one-half of inner. Abdomen moderate, in male with very short 

 truncate tuft ; valves retracted. Fore wings with vein 11 mode- 

 rately long and oblique. Hind wings as broad as fore wings ; 3, 4, 

 6 approximated at base, 7 out of 6 near origin, anastomosing with 

 8 to near middle. 



Easily recognised by the antennal characters. To 

 this genus belongs also (as I am assured by Snellen)
