 (Type, S. frontale Latr.) 



Head transverse, or subquadrate, with a frontal ledge or carina; ocelli 

 3, in a triangle but widely separated; eyes oval. 



Antenna^ in both sexes iL'-jointed, inserted just above the clypeus, 

 in 9 clavate, the fuuiclar joints submoniliform; in S long, subseta- 

 ceous, the flagellar joints all longer than thick. 



Maxillary palpi elongate, ."i-jointed; labial palpi 3-jointed. 



Mandibles elongate, bidentate, the teeth subequal. 



Thorax ovoid, narrowed into a little neck anteriorly; prothorax dis- 

 tinctly visible from above, dilated at sides; mesonotuni usually with 

 2 furrows; scutellum large, semicircular; metathorax with the angles 

 produced into short spines. 



Front wings with the submargmal remote from the costa and termi- 

 nating in a small stigma from which issues a short stigmal and a short 

 postmarginal. 



Abdomen long, ovate, depressed, sessile, the sides carinated, in 9 

 with 6, in $ with 7 segments, the segments nearly equal. 



Legs of moderate length, pilose, the tibial spurs 1, 2, 2, the claws 

 simple. 



The frontal ledge and the 5-jointed maxillary palpi readily distinguish 

 the genus from Scelio, while the differences in the scutellum and post- 

 scutelluin separate it from AcanthosceUo.
