(Plate XLVII. fig. 6, penis.) THYSONOTIS EPICORITUS. (Plate XLVI. fig. 10.) Bamis epicoritus, Boisd. Voy. Astr., Lep. p. 67 (1832). Hah. N e w Guinea; Port Moresby (Goldie), Waigiou (Wallace, Mus. G. 6c S.), (Mus. Staud.). This insect has apparently never been recognized since it was described by Boisduval. Messrs. Kirby and Miskin in their Catalogues place it as a synonym of T. cyanea, 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.) Cupida arinia, Oberth. Ann. Mus. Gen. xii. p. 465 (1878), xv. p. 523 (1880). ? Bamis albastola, Lucas, T. P., P. E. Soc. Queensl. p. 156, ff. 3, (1889). Hab. 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 B. (= T.) albastola under Cramer's name T. cyanea (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 serrated, the apex itself being produced upwards and terminating in a square tip. Fork long, slender, and deeply divided. Tegumen arms narrow. Penis with inner base bladder-shaped for ^ length, when it suddenly narrows for another \ 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 IS. Australia. THYSONOTIS SMARAGDUS, sp. n. (Plate XLVI. fig. 5.) d. 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 ot the whitish patch in T. arinia, and nn 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 |
