94 HYMENOPTEEA. 



Hab. Mexico, Presidio, near Mazatlan (Forrer). 



The face is smooth, shining, impunctate; over the mouth is a short transverse 

 groove, and there is a small indistinct fovea on either side of it ; above the antennae 

 the front is deeply excavated. Thorax covered with black hairs; mesonotum and 

 scutellum coarsely but not very strongly punctured ; pleurae smooth, shining, impunctate, 

 and with a large oblique excavation in the middle ; the scutellum is bordered behind, 

 but there are no teeth. The metathorax has a central keel to the middle, having a 

 large area on either side, and ending in a smaller area, which is broader than long. 



There are no lateral teeth. Petiole is short, not being much longer than one third 

 of the length of the coxae. The rest of the abdomen forms a longish oval, and is shorter 

 than the posterior coxae. The teeth on the femora are blunt and not very closely set ; 

 the basal three, however, are closely pressed together. Alar nervures fuscous. The 

 thorax is darker than the abdomen in colour, being honey-yellow. In the female the 

 abdomen is nearly oval, more obtuse at the apex than at the base. The ovipositor 

 proper projects a little, but not its sheath. 



S. delicatula, Cresson, from Texas, comes near to, if it be not actually identical with, 

 the present species ; but the Texan species is described as having the thorax " imper- 

 ceptibly punctured, almost smooth," and the femoral teeth "numerous, very minute," 

 terms which scarcely fit.
