This species once seen can scarcely be mistaken for any other of 

 the known species of Stictia. The thorax and propodeum are black, 

 sometimes wholly black, but usually with very small lateral spots on 

 the scutellum, on the sides of the mesothorax, and on the posterior 

 lateral angle of the propodeum. Sometimes there are traces of yel- 

 low on the prothorax. The paired discal spots on tergites 1 — 4 are 

 small, widely separated from one another and widely separated from 

 the small lateral spots on the same segments. The legs are black, 

 with traces of yellow or ferruginous, especially on the front pair. 

 I have at hand one male and eight females of this species.

This species most closely resembles Stictia punctata, from which it 

 may be distinguished by the presence of fasciae on the scutellum and 

 the metanotum and usually also on the propodeum. I have at hand 

 one male and four females that I have referred to this species. The 

 male has the fasciae on the scutellum and metanotum very narrow, 

 and the fascia on the propodeum is reduced to a pair of small lateral 

 spots. The posterior lateral angles of the propodeum bear yellow 

 spots. There are small lateral spots on the scutum above the base of 

 the wings, a small spot on the mesopleura below the wings, and a 

 fascia on the pronotum that does not reach the tubercles, which are 

 wholly black. The maculations on the abdomen are characteristic of 

 the species. The apex of the lateral spine of the seventh tergite is 

 obliquely truncate and its posterior angle is bluntly pointed. The 

 male is large and robust, as is also one of the females. Two of the 

 females are much smaller than the others and they have the scape 

 wholly black. One of these two has the clypeus black and the yellow 

 on the labrum reduced to small lateral spots ; the other one has the
