Rcinsuiii. of the (/i;it.i(-s Spilosoma (iiid t/ie allied (jrunih^ of the 

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



Tlie yeiiem of Airfiiihe into which Sjillosmua 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 are useful, and on 

 that account I adopt them. 



The following species do not In-long to this group of genera. — 

 Splludoiiia inariiioi'ata, which is a Diyama (a genus probaUy 

 allied to Deiciteia) ; K ndiMceiix, which is congeneric with Arctia 

 sfriyatida ; S. sabiiLacida, ohsainiin, and Aloa i'hodopli(ea, whicli 

 will together form a genus not far from A/ape ; K fidrla which 

 seems to me to be a mutdated Hypfsa ; S. ri)dat((, something like 

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

 crosa ; and Cre.atonotos ? vaterla. 



Spdaxoiud. dili'.c.ta, Boisd. may be anything, it cannot, 1 tliink, 

 belong to the group.

Walker refers this species to Ifypitrnnupa, but I am saiistied 

 that its true position is in Areas, notwithstanding the startling 

 differences in the iiattern of the primaries.
