] 1 6 SPOLIA ZEYLANICA. 



Post-petiole smooth, shining, impunctate, the mark on the centre 

 of the metanotum longer than broad ; two widely separated 

 marks on the mesopleurse, panthonce. 



21. — Bathythrix ? rvbrioniatus , sp, nov. 

 Plate B, fig. 4. 



Black, the upper part of the propleurse and mesopleurae, the meso- 

 notum, and the scutellum dark red ; the lower part of the propleursp 

 yellowish; the apex of the first abdominal segment at the sides broadly- 

 testaceous ; the apex of the third and fourth yellow, the latter only 

 narrowly. Four front legs dark fuscous, the hinder blackish, tlie 

 coxae behind, trochanters, and the base of tibiae white. Wings 

 hyaline, a broad cloud, rounded and narrowed in front behind the 

 transverse median and the transverse basal, and a much broader one 

 extending from near the base of the stigma to the end of the radial 

 cellule, the centre of the apex of the wings, being hyaline ; the apex 

 of the hind wings smoky. Antennae fuscous, darker at the apex, V. 



Length 6 mm.; terebra 1 mm. 



Peradeniya, April. 



In Ashmead's tables this species would run into the genus Bathy- 

 thrix, but not having a specimen of that genus for comparison I can- 

 not say if it be really identical with it or not. In my species the 

 parapsidal furrows are deep, striated, and broadly rounded behind, 

 not reaching to the scutellar depression. The areolar is 6-angled, 

 narrowed behind and much longer than wide ; there is a distinct 

 petiolar area ; the base of the segment is deeply depressed. The 

 head (including the clypeus) and thorax are thickly covered with 

 white long pubescence. Mesonotum aciculated. Scutellum laterally 

 keeled to near the middle. Median segment closely, finely punctured. 

 Petiole closely, distinctly, ongitudinally striated ; the second and 

 third segments are closely punctured. First joint of flagellum as 

 long as the second.

 Plate B, fig. .'). 



Black, the antennal scape, the base of prothorax, tegulae, tubercles, 

 the base of the basal four segments of the abdomen broadly and of 

 the last narrowly, yellow. Legs rufo-testaceous, the apical four coxae 

 and trochanters and the base of the hind tibiae yellow. Wings 

 hyaline, a black cloud behind the transverse median nervuie and a 

 large one beginning at the base of the radial cellule, extending to near 

 its apex and more dilated on the outer side below than on the upper ; 

 there is a fuscous cloud near the apex of the hind wings, ?, 



Length 7 mm.; terebra 1 mm.
