Mr. A. G. Butler on the Genus Terias. 215 



tlie costal and apical borders broadly flesh-coloured, with 

 golden reflections ; internal area sulphur-yellow : secondaries 

 flesh-coloured, with the usual markings indicated by a few 

 brownish scales. Expanse of wings 35 millim. 



N.E. Australia. 



This species, though extremely like T. sinta on the upper 

 surface^ differs wholly in the coloration of the under surface. 



Terias smilax group. 



This, as I have stated, is completely linked to the T. drona 

 group, and it passes on smoothly enough to T. forviosa and 

 allies ; but nevertheless it will be convenient to restrict 

 it to the following, so far as our named specimens are con- 

 cerned : — 



T, nelplie^ Feld. ; T. smilax^ Donov. ; T. smilacina^ Feld. ; 

 T. chilensis^ Blanch. ; T. deva, Doubl. ; T. pauUna, Bates ; 

 T.Jlavilla^ Bates; T. leuce^ Boisd.; T. diodlna^ Butl. 



Terias dina group. 



Consisting of a few species slightly deeper in tint than the 

 preceding, and, as" a whole, exhibiting rather more distinction 

 in the pattern of the sexes. The following named ones are in 

 the Museum : — 



T. mimulusj Butl.; T. Westwoodii, Boisd.; T. dina, 

 Hiibn. ; T. calceolaria, Butl. 



Terias formosa group. 



Differing principally from the preceding in the brighter 

 yellow colour of the upper surface and immaculate under 

 surface, in which characters, however, the species closely 

 approach T. Jiavilla and T. leuce. Three species are in the 

 Museum : — 



T. formosa, Hiibn. ; T. Jiarina, Horsf. ; T. hutyrosa, Butl. 



Terias hianda group. 



A little brighter in tint than the preceding and with more 

 or less prominent markings on the under surface. 



T. mandarina, De I'Orza : T. attenuata, Moore ; T. con- 

 nexiva, Butl. ; T. fimbriata, Wall. ; T. narcissus, Butl. ; T. 

 hianda, Boisd. ; T. Desjardinsii, Boisd. ; T. aliena, Butl. 



Terias attenuata, Moore. 

 We have this species from Loo-choo (Oo-Sima) ; it corre- 

 sponds with slightly-marked specimens of T. connexiva on the 

 upper surface, but the under surface shows its affinity to T. 

 Jimhriata, being marked after the manner of T. casiope.
