rounder ; hind wing with a hyaline spot also below base of 

 cell. 



Expanse, — c^ 32 mm., ? 36 mm. 



1 c^ ? captured in copulation, Okaba, January 1913 (^Rev. 

 Fv, P. Verienten, M.S.C). 



Arctiidae. 



Stenocyttara, gen. nov. {Lithosiinaricm)^ (Text-fig. 2.) 



c^ . Proboscis present ; palpi sliglit, porrect, reaching frons. 

 Antennas slender, feebly serrate, with two rows of bristles 

 and fasciculated cilia. General aspect and shape of fore 

 wing as in Eiigoa, Wkr. Cell very narrow^ ending in one 

 single acute angle, broadest at origin of vein 2 — ^. e., before 

 middle ; 3 at |, 4 in the middle between 3 and 5 ; 5 and 

 stalk o£ 6, 7, 8, 9 from angle, 10 before it, 11 from cell at 

 the same distance as 4, anastomosing with 12. Hind wing : 

 cell regular, 2 at |, 3 before angle, 4 from it, 5 above it, 6 

 and 7 stalked, 8 from beyond middle of cell. 



Considering the unusual formation of the cell in fore wing, 

 one would expect to find the cause of it in the presence of 

 some sexual marking — however, I was unable to find anything 

 in that line.
