INSECTS OF SAMOA. 



so as to suggest under a hand-lens pronounced teeth. But inasmuch as these 

 scales (which are dark and conspicuous in several of the species, including 67. 

 Jepta) can be more appressed, or may become abraded, much caution is needed 

 in judging of the exact conditions. 



21. Gymnoscelis upolensis Rebel. 



2 Beiheft Jahrb. Hamb. Wtss. Anst., xxxii, 131, 1915 (Upolu : Apia). 



Rebel founded this species on a pair of specimens taken at light by Dr. K. 

 Friedrichs, the with a fore wing length of 8 mm., the palpus short, the abdomen 

 very long, the $ smaller (a fore wing 6 mm.), with palpus twice as long ; " antenna 

 in both sexes finely dentate.'" The postmedian line of the fore wing has its 

 principal angle near the costa instead of — as in 67. lepta — in the middle of the 

 wing ; Rebel places the angle " at vein 7," but I suppose its precise point to 

 be between 7 and 6 ( = SC 5 and R 1 ), as in the specimen which I am referring to 

 this species, as well as in the group generally (67. imparatilis Walker, etc.). 



A $ with the fore wing almost 8 mm. in length and with a more reddish 

 suffusion than in Rebel's types, much as in the reddish and not very variegated 

 forms of 67. pumilata Hiibner, was taken by Buxton at Apia, 29.L1924, and may 

 with a fair degree of probability be assigned to 67. upolensis. I think that the 

 same species, in a more brownish form and with a rather heavy postmedian 

 line, occurs in the Marquesas Is. (Nuka Hiva, 2 2 in Mus. Brit. ; " 300 

 feet," 1 C. L. Collenette, " St. George " Expedition), and I doubt whether 

 it will prove more than a form of the species which I call 67. imparatilis Walker 

 (1865) ; the latter is probably very variable and has been described under 

 many different names, although it is quite possible that at present two or more 

 species are confused together. A few years ago I provisionally separated : 



(1) 67. imparatilis Walker, 1865 (Sarawak) = 67. subtristigera Walker, 1866 

 (Sarawak) = (ab.) 67. peranyusta Warren, 1897 (Sarawak). Wings of the <$ 

 very narrow, in the type — but not in the other cited forms — reddish beneath. 

 Distal area without prominent white admixture. Penang ; Borneo ; ? Moluccas. 



(2a) 67. indicata indicata Walker, 1866 (Sarawak) = 67. confusata Walker, 

 1866 (Sarawak) = (ab.) 67. semivinosa Warren, 1896 (Java) = ? (ab.) 67. semial- 

 hida Walker, 1866 (Borneo). Wings of $ rather less narrow. Distal area of 

 hind wing usually with much admixture of white in posterior half. Ceylon ; 

 India ; Malaya ; Java ; Borneo ; Formosa.
