184 HYMENOPTEEA. 



of the antennae are dark fuscous; but it may be at once distinguished from that 

 species, and from S. rogersi, by the long and slender (not curled) antennae, the more 

 slender body, the eyes converging more at the top, and the absence of the clear space 

 in the discoidal cellule. The apex of the labrum and clypeus is shallowly sinuate ; 

 the hinder ocelli are separated from the eyes by twice the distance they are from 

 each other ; the median segment is indistinctly striated ; the body is deep velvety- 

 black ; the head and thorax are pilose ; the hairs on the pygidium towards the apex 

 are dull fulvous. 



The male is similarly coloured to the female, and it has the antennae equally long 

 and slender. The genital organs are very different from those of S. rogersi, as will be 

 seen by reference to the figures.

Black, velvety ; the head and thorax densely pilose ; the wings reddish-fulvous, 

 black at the base and apex. Eyes slightly converging beneath, hardly at all above ; 

 the ocelli in a curve, the hinder ones separated from the eyes by a somewhat greater 

 distance than they are from each other. Antennae stout, the apical joints a little 

 dilated. Median segment transverse at the apex, slightly transverse-striated. Alar 

 neuration as in S. mexicanus. The long spur on the hind tibiae reaches to the middle 

 of the metatarsus. 



This can hardly be the S. ustulatus of Dahlbom or Taschenberg.
