Hindwings: orange, with a black holder; ou the inner margin this border 

 runs np to the base and lias a projection towards costa above the anal angle ; 

 the margin between veins 2 and 4 opposite the sinus is very narrow, the j-ellow 

 ground in the ? almost toucliing the margin, while at the apex it is much 

 broader, with two curved projections; fringe of liindwings black; of forewings 

 black, with a white patch above anal angle and below ai)ex, but much less strongly 

 so than in hyaloplaga Warr. 



Underside like upper; in the forewings the inner blotch runs, as above, from 

 the costa, while in hyalaplaya it starts from the base. Head, thorax, and abdomen 

 all black. 



E.xpanse of wings : cJ, 24 mm. ; ? , 26 mm. 



Two (JcJ, one ?, from the Tenimber Islands, July 1892 (W. Doherty). 



Nearly related to B. hyaloptaf/a from Humboldt Bay, New Guinea, but certainly 

 distinct. 



157. Bursada hyaloplaga sp. nov. 



(?. Foreivi ngs : deep brown-black, the costa shouldered at base and with a semi- 

 liyaline blotch within it ; a small fulvous blotch in cell, more or less obscured by 

 dark scaling; an oblique oval yellowisli blotch from below two-thirds of costa towards 

 anal angle, shaped as in synestia ^leyr., but without any red tinge ; fringe dark, with 

 ])ale patch above middle and anal angle. 



Hindivinrja : yellow, with all the margins black ; a small black tooth on costal 

 margin facing that above anal angle ou inner margin ; the yellow without any red 

 tinge ; fringe wholly black. 



Underside the same, but the spot in cell of forewiug clear yellow and narrowed 

 to the base. Face, palpi, head, thorax, and abdomen all blackish ; sides of abdomen 

 yellow. 



Expanse of wings : 28 — 32 mm. 



In some numbers from Humboldt Bay, New Guinea, October 1892 (W. Doherty). 



Distinguished from both fulvimacula Warr. and synestia ISleyr. by the 

 absence of the red tint, and by the semihyaline space at base of costa in the cJ. 



In a few cases the oblique blotch (which is considerably variable in shape and 

 size) touches the costa ; and in one example, where this blotch is more than usually 

 developed, the obsolete basal patch has a yellow spot on costa above it. 



158. Bursada oppositata sp. nov. 



Bivrsada salamandra Kirsch, Mltth. Dresd. Mas. I. (1877), i>. I.S:) (part), nee figure. 



Kirscli appears to have confused two species : his description and figure ajiply 

 exactly to Koisduval's xanthomelas; but lie adds that some examples showed a 

 tendency to throw off a black streak from the anal angle. I have before me both 

 forms from Humboldt Bay ; in this latter form, for which I propose the name 

 opposilata, not only is the protuberance from the anal angle prominent, but there 

 is a correspondiug, though smaller, prominence from the costal black margin 

 opposite. In the forewings the vellow basal blotch is more interrupted by the 

 protrusion into it of the black iuner margin, this protrusion having generally an 

 irregular triangular form.
