black borders being much narrower on both surfaces and also by 

 having less metallic blue at tiie bases of the wings above.

Thysoxotis epicoritus. (Plate XLVI. fig. 10.) 



Damis epicoritus, Eoisd. Voy. Astr., Lep. p. 67 (1832). 



Hah. New Guinea; Port Moresby (ffoMie), "Waigiou {Wallace, 

 Mus. G. 4' S.), (Mus. StmicL). 



This insect has apparently never been recognized since it was 

 described by Boisduval. Messrs. Kirby and Miskin in their Cata- 

 logues place it as a synonym of T. ct/anea, Cr.. but a reference to the 

 figure here given, which is taken from a specimen in Messrs. 

 Godman and Salvin's collection from Port Moresby, obtained by 

 Goldie, will at once show that it presents considerable differences 

 from that species. The female is unknown. 



Thysonotis arinia. (Plates XLVI. figs. 6, 7 ; XLVII. figs. 7, 7a.) 



Gnpida arinia, Oberth. Ann. Mus. Gen. xii. p. 465 (1878), xv. 

 p. 52.3 (1880). 



? Damis albastola, Lucas, T. P., P. E. Soc. Queensl. p. 156, ff. 3, 4 

 (1889). 



Bab. Queensland, N. Australia. 



Through the kindness of M. C. Oberthiir I have been able to 

 examine the type of this species, which is from Queensland. 



The figure of the male here given is from a specimen in our own 

 collection from N. Australia, which agrees exactly with the type, 

 and that of the female is one of several received with it. I place 

 Mr. Lucas's species somewhat doubtfully as a synonym, as I have 

 not been able to examine his description and figures. 



Mr. Miskin, to whom T. arinia was unknown, has placed D. (= T.) 

 alhastola under Cramer's name 2\ o/anea (Ann. Queensl. Mus. 

 no. 1, p. 50, 1891). 



Genitalia. Clasp broad, united at each lower extremity from the 

 apical lower end to the tip ; the margin is crescent-shaped and is 

 strongly seri-ated, the apex itself being produced upwards and 

 terminating in a square tip. Pork long, slender, and deeply 

 divided. Tegumen arms narrow. Penis with inner base bladder- 

 shaped for 5 length, when it suddenly narrows for another 5 and 

 at the apical third expands again into a swollen joint, whence it 

 tapers to tip. (Plate XLVII. figs. 7, 7a.) 



The description is taken from a specimen received from N. 

 Australia. 



Thysonotis smaragdtjs, sp. n. (Plate XLVI. fig. 5.) 



S . Allied to T. arinia. Upperside much the same but with a 

 small white dot at the end of the cell of the fore wing in place of 

 the whitish patch in T. ai-im'a, andan indistinct white blotch in the 

 cell of hind wing. Underside : borders blacker and more distinctly 

 defined ; outer marginal border of fore wing narrower than in
