44 HYMENOPTERA. 



JAPANIA genus novum. 



Normal position. 



A genus resembling Lathromeris Foerster in general ap- 

 pearance but differing in having two distinct funicle joints 

 in the antennae ; more closely allied with Ufens Girault and 

 Ittys Girault, differing from the former in having the funicle 

 distinctly divided into two subequal joints, combined smaller 

 than the pedicel, in having a conic-ovate abdomen as long as 

 the head and thorax combined and more slender fore wings 

 without peculiarly distinct lines of cilia, the discal ciliation 

 moderately dense, arranged in regular lines none of which, 

 however, are conspicuous as in Ufe?ts ; also from the last 

 named genus indirectly in having no sexual antennal dimorph- 

 ism. From Ittys this genus differs in the decidedly shorter 

 marginal vein of the fore wing, in the less sharpened and 

 shorter abdomen, in the shorter marginal ciliation of the 

 fore wing and in its much smaller build in general. 



Female. — Body slender. Tarsi 3-jointed. Pubescence of 

 fore wings arranged in regular lines. Venation straight. 

 Ovipositor not exserted. Antennae 8-jointed — scape, pedicel, 

 one ring-joint, 2-jointed funicle and 3-jointed club, the latter 

 cylindrical-ovate, long, the first funicle joint nearly twice the 

 size of the second, the pedicel longer than their combined 

 length ; ring-joint distinct. Fore wings convexly rounded at 

 the apex, the marginal ciliation moderately short, the discal 

 ciliation uniform and moderate in density, the oblique line of 

 cilia running back from the stigmal knob present, consisting 

 of about six cilia ; at their widest portion, the fore wings with 

 about fifteen lines of discal cilia. Submarginal vein two and 

 a half times longer than the marginal, widening distad where 

 it breaks nearly to the width of the marginal vein, the latter 

 short, straight, rather thick, slightly longer than the stigmal 

 vein which is moderately strong, moderately long, terminat- 

 ing in an ovate knob with an acute uncus pointing distad pro- 

 jecting from its distal margin at the middle ; its neck short, 

 slender. Posterior wings without the usual discal cilia at 

 the edges, with three longitudinal lines of them within, the 

 first (cephalic) two side by side near the cephalic margin.
