beyond the second transverse cubital nervure ; the recurrent nervure is received shortly 

 before the middle of the cellule, the cubital nervure being angled where the recurrent 

 nervure is received.

The antennae are as long as the thorax, pale ferruginous ; the flagellum bare, paler 

 in tint than the scape ; the third and fourth joints subequal. The head is not much 

 narrower than the mesothorax, narrowed behind the eyes, where it is developed a little 

 longer than their length, the sides rounded ; it is covered with long pale hair, and is 

 indistinctly punctured and shining ; there is a furrow round the ocelli. The mandibles 

 have the tips black ; the base is covered with long white hair. The thorax is covered 

 all over with long white soft hair. The mesonotum is rather strongly punctured, but 

 with the punctures clearly separated ; the parapsidal furrows deep. The scutellum is 

 also strongly punctured and has thick hair. The median segment has a gradually 

 rounded slope ; above it is strongly reticulated and covered with long white hair. The 

 pleurae are reticulated, except the part between the meso- and metapleurae, which is 

 smooth, shining, and glabrous ; they are elsewhere covered with long soft fuscous hair. 

 The abdomen is nearly as long as the head and thorax united, and distinctly wider 

 than the latter. The petiole is gradually dilated towards the apex ; its punctuation is 

 very obscure, if not obsolete, and it is sparsely covered with long white hair. The 

 second segment is not much longer than the petiole ; smooth, shining, and impunctate, 

 covered all over, as are also the other segments, but much more thickly, with long 

 white hair. The ventral segments are smooth, shining, and impunctate, and covered 

 with long soft white hairs. The wings are clear hyaline, without any smoky tinge ; 

 the nervures are pallid testaceous, the costa and the stigma having a deeper and darker 

 tint ; the radial cellule is a little shorter than the first and second cubital cellules 

 united ; the first transverse cubital nervure is curved, the second is straight and slightly 

 oblique ; the recurrent nervure is received in the basal third of the cellule ; the trans- 

 verse basal nervure is almost interstitial. The legs are of a paler testaceous tint than 

 the body, being pallid yellowish-testaceous, with the apex of the hind tibiae and the 

 four hinder tarsi for the greater part blackish ; the calcaria are blackish. 



The following (S. cowqualis) is a well-marked species. The antennae are short and 

 thick j the entire body is densely covered with long white hair ; the thorax is coarsely 

 punctured ; the abdomen is elongate and with a rather long petiole ; the legs are more
