Margarodes diaphanalis, Walk. 



Margaronia diaphanalis, Walk., SuppL, 1365; Botgs 

 margaronialis, ib., 144:2. 



5 , 29 mm. Head, palpi, antennae, thorax, and abdomen 

 shining white ; lower part of face greyish ; palpi towards apex 

 dark purplish-grey ; shoulders narrowly fuscous-grey. Legs 

 blackish ringed with white, posterior pair white. Fore wings very 

 elongate-triangular, costa posteriorly gently arched, apex obtuse, 

 hind margin slightly rounded, very oblique ; iridescent white ; a 

 narrow dark fuscous costal streak from base to apex, posteriorly 

 attenuated ; a black transverse discal dot ; a siibmarginal series of 

 conspicuous black dots ; cilia shining white. Hind wings and 

 cilia iridescent white ; sometimes hind-marginal dots as in fore 

 wings. 



Cairns, Queensland ; one specimen (coll. Macleay). 

 I have compared Walker's specimens of margaronialis ; 

 but his diaphanalis, which is not in the British Museum 

 collection, I have identified from description ; however, 

 I believe there is little doubt about it. The former is 

 from Java, the latter from Aru. I think it not im- 

 probable that M. plwmifera, Butl. (Ann. Mag. N. H., 

 1882, 236), from New Britain, may be the male of this 

 species. 



Margarodes tritonias, n. s.

 anal tuft blackish ; anterior and middle tibiae suffused with 

 ochreous, middle tibise shortly ' rough-scaled above. Palpi bright 

 yellow-ochreous, lower half of labial white. Fore wings elongate- 

 triangular, costa posteriorly moderately arched, apex obtuse, hind 

 margin almost straight, oblique; iridescent greenish-whitish; a 

 moderate pale ochreous costal streak, becoming obsolete towards 

 apex, costal edge purplish-tinged ; a blackish discal dot ; a hind- 

 marginal series of minute black elongate dots ; cilia white. Hind 

 wings iridescent greenish- whitish ; a very fine blackish hind- 

 marginal line, tending to be interrupted ; cilia white.
