Revision of the (jenns tSpilosoiuu oitd the allied (jroaps of the 

 Family Arctiidct; by Arthur G. Butler, F.L.S., F.Z.S., &c. 



The genera of Aivtlldie intu which Spllosoma has been divided 

 are closely allied ; their structural differences are such as would 

 not be recognized in many families as of generic value ; still, as 

 sub-divisions of a large group of insects, they arc useful, and on 

 that account I ado])t them. 



The following species do not l)elong to this group of genera. — 

 Spilofioma inaniiorata, which is a Dlyaiiui (a genus probably 

 allied to Delo/)el(i) ; S. ndiesnu/s, which is congeneric with Ardla 

 strigatula ; S. .subinar/da, ohsnir/nn, and Aloa rhodophiea, Avhich 

 will together form a genus not far from Alope ; S.f/dria. which 

 seems to me to be a mutilated Hypsa ; S. costata, something like 

 the latter and of doubtful location ; Aloa, tripartita, dentata, and 

 erosa ; and Creatonotos ? vuterla. 



Spdosonia dijcrta, Boisd. may be anything, it cannot, I think, 

 belong to the grouj).

Walker refers this species to Hypercoiiipa, hnt 1 am satisfied 

 that its true position is in Areas, notwithstanding th(! startling 

 differences in the pattern of the primaries.
