description) are unusual ; probably they are extremely adult ; ordi- 

 narily the metallic reflections are absent, or slightly bluish. The $ 

 has the wings strongly tinged with yellow (much more strongly than 

 in the ? of luctuosa), and the lateral lobes o£ the labium are yellow 

 (as is noticed byAlbarda). This species, at first sight, is extremely 

 similar to V. hictuosa, so common in Java, but the ^ can be at once 

 separated by the body not being metallic, and the ? by the yellow 

 lateral lobes of the labium, and the more strongly tinged wings. 



De Selys (J. c.) compares it with V. melania of the Philippines 

 rather than with luctuosa, and thinks it may be only a local race of the 

 former. To me it appears distinct from either, but most closely allied 

 to luctuosa. I do not detect the apparently small increase in the 

 breadth of the wings (mentioned in the original description) as com- 

 pared with luctuosa. 



EuPH^A BocKi, n. sp. 



S (adult). Length of abdomen, 34 mm. Length of posterior whig, 28 mm. 

 Breadth of anterior and posterior wings, 6^ mm. Length of pterostigma, 3 mm. 



Wings narrow, the posterior not dilated : both pairs slightly tinged with oliva- 

 ceous : the apex of the anterior pair from slightly after the commencement of the 

 pterostigma, and of the posterior from slightly before, suddenly blackish-brown, this 

 apical dark space straight internally : on the posterior wings (only) the dark colour 

 is continued in the area between the median neryure and the principal sector (but 

 not in the costal area, excepting towards the pterostigma) up to within part of the 

 cellule after the nodus ; this continuation is darker in colour than the apical portion, 

 and has brilliant steel-blue reflections both above and beneath (wanting in the apical 

 portion). Pterostigma black, surmounting 7 — 9 cellules. Nodus placed midway 

 between the base of the wing and the end of the pterostigma. 21 — 24 ante-cubital 

 nervules and 21 jwst-cubital in the anterior wings ; 18 — 21 ante-cubital and 19 — 23 

 post-cubital in the posterior : quadrilateral not reticulated (perhaps accidentally) in 

 all the wings. Nodal sector commencing half a cellule before the nodal nervule. 



Head black ; clypeus and labrum shining, the latter with two very large yellowish 

 (perhaps bluish in life) spots bearing only a median band, and the margins, black ; 

 on the face the margin of the eyes, as far as the insertions of the antennae, are broadly 

 yellowish (or bluish ?). 



Prothorax black, with a large oval brown swelling on either side. 



Thorax black ; the sides and breast yellowish spotted with black, one spot con- 

 tinued as a line half way along the metathoracic lateral lobe. Interalar space 

 spotted with yellowish (or brownish) . Legs black ; femora yellowish (or brownish) 

 internally. 



Abdomen black, slightly bronzy : a yellow line along the sides of segments 

 1- — 5 (becoming very narrow on 5), interrupted at the sutures ; the dorsal crest on 

 segments 2 and 3 very finely yellowish, interrujDted at the suture ; tlie posterior 

 genital piece on segment 2 very large, produced on each side into a conical tooth
