wliich is half as long again as the third, tlie flagellum 

 thickened towards the apex. Thoiax finely and very closely 

 punctnred^ clothed with short greyish pubescence ; ahdomcu 

 more sparsely punctured. Hind calcaria broad, blunt at the 

 apex, as long as the second, and tliird joints of the hind 

 tarsus combined. Second abscissa of the radius very short, 

 about one-quarter of the length of the first transverse 

 cubital ncrvure, and a little shorter than the distance 

 between the two recurrent neivures on the cubitu?*, the 

 second recurrent ncrvure received as near to the first as 

 to the apex of the second cubital cell. The abdomen is 

 not much broadened to the base, much less so than in 

 grandidieri.

In the shape and markings of the ab ^omen this species 

 approaches the S. American >S'. spectabilis, Tasch. The form 

 of the clypeus is near S. yi-andklieri, Sauss., from Avhich it 

 differs much in colour, in the more slender form, in the less 

 dilated hind calcaria, and in details of neuration.
