1893.] THE BUTTEEFLTES OF THE GENT7S THXSOXOTIS. 543 



THTSOIfOTia EIBBEI. 



Pleheius nhbei, Eober, Iris, i. p. 52, pi. iv. f. 2, S (1886)*. 



JIah. X.W. Xew Guinea, Sekar. 



This species seems to differ from all others by having a narrow 

 metallic line between the usual broad fascia and the margin on the 

 hind "ning below. It is kno\\Ti to us only from the figure. 



The female is undescribed. 



Thtsoxotis philostratps. (Plates XLV. fig. 8, XLVII. figs. 3, 

 3 a.) 



Lycana pliilostratus, Feld. Eeise Nov., Lep. ii. p. 264, t. 33. 

 fE. 1, 2 (1865). 



Cupido philostratus, Kirby, Svst. Cat. p. 346 (1871) ; Oberthiir, 

 Ann. Mus. Genova, xv. p. 522 (1880). 



c? . Upperside much like T. apollonius (S , but of a more vio- 

 laceous shade of blue. 



Underside as $ , but white central band, as is usual, rather wider. 



Hab. Gilolo (jPeWe/-) (Platen in ATus. Stand.) (Wallace in Mns. 

 G. ^ S.) ; Batchian (Platen) ; Waigiou (Mus. G. S,- S.) ; Batchiau 

 (Doherty) (Mus. D.) ■ Ternate (Oberthiir). 



This is an easily distinguished species and does not appear to 

 vary except in size — a small female from Batchian in Messrs. 

 Godman and Salvin's collection measuring only 1| inches, a large 

 one from Waigiou 2 inches. 



Genitalia. Clasps somewhat bottle-shaped, but rounded at the 

 base, and the neck (continuing the simile) thick, the apices being 

 bluntly toothed. Tegumen with sides fully developed ; hooks of 

 moderate length and rather slender. 



Penis decidedly short, very stout, similar in shape to T. ajjol- 

 lonius. (Plate XLYII. figs. 3, 3 a.) 



B. The WALLACEi group. 



This is a small group which contains insects of somewhat less 

 robust appearance than the preceding and which have the cilia of 

 both sexes pure white, not alternately black and white as in danis 

 and allies. 



Unfortunately very little is known of them, as Aery few are con- 

 tained in collections. They are certainly some of the most beautiful 

 of the genus. 



Thtsonotis wailacei. 



Lyca;na wallacei, Peld. Eeise Nov., Lep. ii. p. 265, fE. 8-10 

 (1865) \ 



Cupido wdllacei, Kirsch, Beitr. Lep.-Faun. von Neu-Guinea, 

 p. 126 (1877) ^ 



Hab. Waigiou ' ; Mysol ( Wallace) (Mus. G. 6,- S.) ■ N. Guinea, 

 Ansus, Kordo, Eubi ^\ 



The specimens from Mysol are rather smaller than Dr. Telder's 

 figures, and the male has rather less white on the disks.
