5 . Head from antennae to the sharply bordered posterior 

 margin coarsely arcuate rugose; anterior frontal tubercle scarcely 

 larger than the lateral ones, posterior pair smaller, the space 

 between tubercles centrally smooth. Flagellar joints normal. 

 Pronotum elongate, with apical transcarina, posteriorly tiuns- 

 striate, laterally smooth and shining. Mesonotum and median 

 segment smooth, coarsely and diffusely punctate. Scutellum 

 smooth and shining, coai-sely punctate on margins of lobes. 

 Propleurse nearly smooth ; meso- and meta-pleuras coa.rsely and 

 diffusely punctate, former anteriorly subrugose. Petiole coarsely 

 and closely trans-striate, as long as rest of abdomen ; second 

 segment smooth and shining, four times as long as broad ; 

 remainder transverse, shagreened, and shining, Terebra about 

 half as long again as body, sheaths white-banded before apex. 

 Middle and hind coxae smooth, with Avhitish pubescence ; hind 

 femora smooth, bidentate ; tibiae compressed to middle. .Stigma 

 very long and pointed. 



Black ; head except apices of mandibles, two basal antennal 

 joints, front legs except basal third, and hind tarsi red ; inter- 

 mediate legs black-brown. Wings infumate, distally darker, 

 external median and submedian cells and thence to posterior 

 margin brown ; stigma and nervures black. 



Length 24 mm. ; terebra 37 mm.

Distinguished from S. maculipennis AV^estw., especially by the 

 coarsely trans-striate petiole without lateral tubercles ; from 

 S. rnficeps Sauss. it may be known by the arcuate rugose head 

 and darker wings.

 posteriorly centrally transrugose, laterally more irregularly. 

 Temples diffusely and finely punctate. Posterior margin of head 

 with slightly refiexed border. Neck very coarsely trans-striate, 

 semiannular smooth, laterally coarsely punctato-rugose. Meso- 

 notum centrally diffusely punctate, with a longitudinal row of

 smooth above, slightly rugose in front and behind, coarsely 

 rugose-punctate beneath, separated by a deep rugose sulcus fi^om
