364 MR. H. H. DRUCE ON THE [Juiie 2, 



is a short description of JH. lineata, Murray : — Male. Ujjper- 

 side brownish silvery blue, browner at apex. Underside chestnut- 

 brown, with bauds much as in N. vincula, but narrower and not 

 bordered with white as in the female. 



Thysonotis, Hiibn. 



I have followed Herr Semper in using Hiibner's name for this 

 group. There is apparently nothing but what Mr. de Nicevile calls 

 " facies " to distinguish it from Nacaduba.

Thysonotis kruera, sp. n. (Plate XXXI. figs. 16c?, 17 $ .) 



Male. Upperside dark violaceous blue, narrowly margined with 

 dark brown ; cilia dark brown. Underside pure white, with costal 

 and outer margins of primaries dark brown, broadest at the base. 

 Secondaries brown at the base and the outer margin, on which is a 

 row of small, irregular, metallic blue spots with a few scales above 

 them towards the anal angle ; a few metallic scales near the base 

 just outside the brown. 



Female. Upperside dull greyish brown, with the disk, from the 

 base, dull light violaceous blue ; hind wing with the outer margin 

 darkest, slightly bluish towards the base. Underside as in male. 



Head and thorax dark brown ; abdomen brown, annulated with 

 white as the bases of the segments ; antennae and legs dark brown 

 spotted with white. 



Expanse, 6 $ lyTj i"ch. No tail. 



Florida I. ( c? )• N.W. Bay, Malaita I. ( ? ). 



This species is allied to T. hymetus, Feld., from Amboina, but is 

 darker blue above, and the female is very different, and to T.piepersii, 

 Snellen, from Celebes. 



Thysonotis cepheis, sp. n. (Plate XXXII. figs. Id', 2 $ .) 



Male. Upperside silky violaceous blue, with the margins narrowly 

 and evenly black ; lighter in the disk of tlie fore wing. Underside 

 allied to T. schaeffera, Esch., but suffused with more brilliant green 

 at the bases and with the outer-marginal band enclosing the black 

 spots, which in that species is light buff, brilliant metallic green. 



Female. Upperside as in T. schaeffera, Esch., female. Underside 

 as in male. 



Head and palpi greenish white ; thorax and abdomen brown ; legs 

 brown and white. 



Expanse, S IjVU i"ch, $ I Jj^ inch. 



Aola, Guadalcanar I. 



In some specimens the outer border only of the band on the 

 underside of hind wing is metallic green, the inner border being buff 

 as in T. schaeffera, Esch. 



T. cepheis can be at once distinguished from that species by the 

 upperside of male being almost entirely blue, in that respect resem- 

 bling another allied species, viz. T. calydonica, Feld., from New 

 Caledonia, which has been placed as a synonym of T. schaeffera by
