of the apical nervures also darker ; the interneural spaces where 

 pale with dots arranged like stripe ; towards the inner marginal 

 region, the dots form irrorations ; pterostigina only slightly marked 

 (all the markings more intense in the 9 )• Posterior wings paler, 

 yellowish, especially at the apex. 



In the ^ the inferior appendages are relatively short ; the basal 

 joint very broad when viewed from the side, ascendant, at about half 

 its length ventrally, a large abruptly inturned tooth occurs preceded 

 by a slightly-marked angle ; the second joint short, when viewed 

 from the side, from its being much incurved ; the apex in some 

 views having the appearance of being slightly emarginate. The 

 lateral lobes are united at the base, long, finger shaped, slightly 

 angulate on their inner margin and terminating in a hooked point. 



In the $ the eighth dorsal segment lias the posterior margin 

 excised, the angles lieing strongly produced. In the type the 

 ovipositor is short. The parts are however not in very good 

 condition. 



Expanse ,^ 45-5 mm., 9 52 mm. 



One of each sex from Japan (Pryer); a large handsome 

 insect. 



3. Rhyaco'phila tccta, n. sp. 



Ninth segment apparently continuous ventrally, dorsal portion 

 not visible in type being probably abnormally retracted in drying ; 

 no ventral teeth visible. Median process long somewhat roof-shaped 

 and sub-acute. 



Wings with apex sub-acute ; apical forks Nos. 1 and 2 sub-equal 

 in the fore wings ; radius not distinctly furcate at apex. Membrane 

 smoky with brownish pubescence, neuration fuscous. Costal hairs 

 simple. 



Antennae blackish fuscous, faintly annulated with paler at the 

 joints ; legs fuscescent. 



In the ^ the inferior appendages have the basal joint elongate, 

 the upper and lower margins being sub-parallel, apical margin 

 oblique ; the second joint is short, its upper and lower edges rounded, 

 apical edge emarginate with several rows of black short setje 

 internally. 



Expanse 18 mm. 



Khasia Hills, one male. 



A pretty little ^ insect with blackish, iridescent wings, 

 marked with some snow-white spots can hardly belong to 

 this species.
