Of tliis species I have at hand one male and two females, each 

 bearing the label, ""Austria." The male of this species may readily 

 be di:;tinguished by the characters found on the middle femur and 

 metatarsus: The femur is dentate below with the middle tooth, the 

 longest one in the row and the metatarsus below at its middle point 

 bears two stout spines and the distal part beyond the spines is slightly 

 curved. The second and sixth sternites bear moderately developed 

 tubercles and the seventh a broad, median carina. The dorsal border 

 of the clypeus is black and from the center the black is extended to 

 form a large medinn spot. The mesothorax, metathorax, and propo- 

 <!eurn are wholly black and the maculations on the obdomen are 

 confined to narrow lateral spots on tergites 1-3. 



On tiie females the fasciae on the tergites are pale, relatively broad, 

 and all continuous on one specimen and all but the fourth continuous 

 on the other. On both specimens the fifth tergite bears only a pair 

 of small round discal spots and the sixth an apical spot. On one 

 there is a narrow, interrupted fascia on the scutellum, traces of an 

 interrupted fascia on the metanotum, pair of large spots on posterior 

 part of the propodeum, a very large spot on the side of the propodeum 

 and another on the metapleura. The side of the prothorax on this 

 specimen is almost entirely pale. On the other female these same 

 macnlations are present but are greatly reduced, especially on the 

 scutellum, metanotum, and dorsum of propodeum. On the sternites. 

 maculations are limited on both females to lateral spots on two and 

 three and to extreme tip of six. On both males and females the 

 second abscissa of the cubitella is lacking.

I have at hand two males and two females that I have referred to 

 this species, and also two males determined by R. H. R. Stevenson.
