? . Antennae a little shorter than the thorax and median 

 spotnent combined, the scape more than half as long as the 

 flagelhim, tlie first joint of the flageliuin longer than the 

 second. Eyes converging a little towards the vertex, poste- 

 rior ocelli about twice as far from the eyes as from each 

 other. Head and thorax very minutely punctured ; the 

 head much broader than the thorax ; clypeus with a median 

 carina, which is continued on the front, almost reaching the 

 anterior ocellus ; antennae inserted far apart on the sides of 

 the clypeus ; front concave in the middle, with a smooth 

 groove on each side of the median carina. Pronotum small 

 and much lower than the mesonotum, the angles reaching to 

 the tegulse. Median segment very coarsely reticulate; the 

 basal area well defined, large, and broadly triangular, with 

 two short longitudinal carinse at the base; the posterior 

 truncation almost vertical, with a small tooth on each side 

 near the middle, the surface of the truncation reticulate. 

 Abdomen subpetiolate, smooth and shining. 8tigma twice 

 as long on tiie costa as the greatest breadth, only one cubital 

 cell, the recurrent nervure received at the middle of the 

 cubital cell ; the transverse cubital nervure received by the 

 radius distinctly nearer to the stigma than to the apex of the 

 radial cell. 



Length 4 mm. 



Hah. Penang ; October (^O. E. Bryant). 



The neuration differs from ty|)ical Spilomena in the 

 absence of the first transverse cubital nervure and in the 

 more elongate stigma. 



Subfamily Ampulicin^.

 leviter infumatis. 



cJ . Clypeus strongly convex, with a median carina, 

 broadly rounded at the apex. Antennae shorter than the 

 thorax and median segment combined, the second joint of the 

 flagellum as long as the first and third combined. Front 

 longitudinally rugiilose, a low frontal carina reaching the 

 anterior ocellus, vertex opaque, almost. smooth. Head much 

 produced and narrowed behind the eyes, a circular depression 

 on the vertex close to the posterior margin. Pronotum very 

 narrow, slightly widened posteriorly, more than twice as long 

 as the greatest breadth, punctured, with a deep median 

 sulcus. Mesonotum, scutellum, and mesopleurse coarsely 

 punctured-rugose. Median segment longer than the breadth
