brown bands, a brown mark in first apical median cell; wings hyaline, 

 brown-veined. Besides being smaller and lighter this species differs 

 from litKrifroiis in having the pygaphor and anal tube much smaller, 

 the anal style shorter and broader and the genital styles less curved 

 and their apices, where they meet, not straight. 



Length 5.2 mm. ; tegmen 5.7 mm.

(3) U. lalol'ensis sp. nov. ( 5 ) 



A single median facial keel, meeting the V-shaped keel of vertex; 

 the first median sector touching the cubitus (no median cross-vein). 

 Light brown; the facial keels, distal half of second antennal joint, 

 apical portion of tibiae and marks on dorsum of abdomen dark brown. 

 Tegmina hyaline, veins brown with very fine, hair-bearing granules, a 

 large stigma at end of costal cell, a brown spot at end of each apical 

 vein, extending along cubital vein to clarus; wings hyaline, fuscous 

 at border, brown-veined. Length of ventral surface of pygophor more 

 than twice the breadth, medio-ventral process about as long as broad, 

 angularly emarginate at apex, ventro-lateral edges of pygophor pro- 

 duced into angular, bent plates; anal segment long, compressed, form- 

 ing a keel along medio-dorsal line, a long, acutely angular depression 

 on ventral basal surface; anal style very small, narrowly lanceolate, 

 genital styles small, slightly curved, flattened, the apices crossing one 

 another. 



Length 6 mm. ; tegmen 7.7 mm. 



Hab. Laloki, Papua. 



This probably represents a new genus, but as there appears 

 to be two forms mixed under Ugyops and Bidis which I cannot 

 separate I place this form with them. 



Melanesia Kirkaklv. 

 (1) M. horneo-ensis sp. nov. ( 9 ) 



Stramineous; a small, black, spatulate-shaped mark on each side 

 of the V-shaped keel of xertex, a round black spot on each side of 

 pronotum behind eyes, ovipositor dark; tegmina hyaline, slightly 

 opaque and yellowish, veins colourless on basal half, brown apically, 

 with numerous inconspicuous granules, a black spot in clavus, an- 

 other small one at base of subcosta, radia, media and cubitus each 

 with small brown spot; wings hyaline, brown-veined, slightly opaque. 



Length 4.G mm. ; tegmen 5.4 nun.
