Euryylossa reject a, sp. n. 



S • — Length about 6^ mm. 



Head and thorax black, with long loose pubescence, more 

 or less fuscous on head and thorax above, otherwise dull 

 white ; head very broad ; eyes converging below ; clypeus 

 •with very close, large punctures, the surface between them 

 shining ; maxillary palpi long and slender ; blade of maxilla 

 more than twice as long as broad, rounded at end ; mandibles 

 bidentate, entirely black ; antennae black, scape with much 

 long hair ; flagellum rather stout, ])ruinose, the last joint 

 with a shining area at the side of the apex ; mesothorax 

 shining, but well punctured ; tegulse very dark brown. Wings 

 greyish hyaline, iridescent, stigma and nervures piceous ; 

 second s.m. nearly as long as first, and receiving the recurrent 

 nervures a moderate distance from its base and apex. Legs 

 shining black, with thin Avhite hair, spurs creamy white. 

 Abdomen black, with the hind margins of the segments 

 broadly ferruginous ; the segments are elevated or gibbous 

 about the middle, the ferruginous margins thus appearing 

 to be abruptly depressed ; the apex terminates in a projection, 

 which might be called spoon-shaped but for its being trun- 

 cate ; on each side of this is an elongate ferruginous lamina, 

 and above it a pair of delicate lamellae placed edgeways ; 

 venter with the basal segment black or almost, the second 

 and third entirely light yellowish ferruginous, the others 

 strongly clouded with brown.
