A very interestin<^ genus, well worth careful inve3ti;^ation. 

 lIeritofV>re, on account of the similarity of pattern, authors 

 have put all the different forms from America to Australia, 

 reganlless of the localitie:?, mostly undt-r tho American form 

 erosa ; in ' Moths of India,' ii. p. 411 (1894), llainpson puts 

 xan'hndipna, Boisd., from Rladayascar, indica, Guen., fiom 

 India, aiiragoides, Guen., from Xatal, variolosa, Walker, 

 from North India, and edentata from Queensland all as 

 synonyms oi erosa, Huhner, from America. 



Staudiiigei", in his Catalogue, 1901 eilition, ])ut3 xauthin- 

 di/ma, indica, and auragoides under the American form. 



Warren, in Seiiz's * ^lacrolepidoptera of the Pahearetic 

 Region/ vul. iii. p. 359 (X^ov. 1913), puts auratjoides, vario- 

 losa, and edenlata as synonyms with x-inthhtdi/ma ; under 

 erota he puts indica. 



Tijo suj)erficial pattern of all these is more or less the same, 

 but there are differences. I could not i^et myself to believe 

 that, notwithstanding- the gaogiaphieal di?tances, lli^-y coul 1 

 all be one and the .*ame species, and consequently I got the 

 Kev. ('. K. X. Burrows, who is an expert on tho genitalia of 

 Lepidoptera, to examine specimens from many diti'erent parts 

 of the globe, and I am very grateful to him and to Mr. F. X. 

 Pierce of Liverj»o(»l fur the pains they have t.iken in the 

 matter. All the Plates arc from drawings by Air. Burrows, 

 iiiid all tho notes on the genitalia are his, many u( them 

 having been submitted to ]\Ir. Pierce for verilic.ilinn. 



Mr. Burrows ^ays that the dissectiuns show a relation^^hip 

 to the Erebusida", to the genera Argioa an<l l*atula in the 

 large extensile cortmata, dorsal of the valves ; he fuither
