posterior orbits, broad below, narrow above; posterior border of 

 pronotum extended around posterior border of tubercle; spot on 

 side of prothorax ; short lateral line above base of wings on scutum ; 

 narrow transverse, rectangular, lateral spots on scutellum; narrow 

 interrupted fascia on posterior border of metanotum; small spot on 

 side of propodeum ; spot on metapleura ; spot on mesopleura ; lateral 

 and discal spots completely separated on tergite one; discal spots 

 separated from one another but united to lateral spots on tergites 

 2-5 ; four distinct spots on tergite 6 ; apical part of tergite 7 ; fasciae 

 on sternites 2-5 broad laterally and almost interrupted by a deep 

 anterior, median efnargination ; fascia on sternite 6 broad in the 

 middle but narrowed laterally; femora in part; tibiae and tarsi 

 wholly; yellow. The color of the maculations on the abdomen, 

 labrum, clypeus, and scape is a very pale creamy yellow, while that 

 on the thorax and legs is a much richer shade of yellow. 



The basal half of the flagellum is ferruginous and none of the 

 segments shows any special modifications. The apical part of the 

 middle femur is dentate below. The median part of the sevenfh 

 tergite is narrow and rounded at the apex while the lateral spines 

 are short, rounded, and sharply pointed. 



Allotype (female). — The allotype, with respect to the macula- 

 tions, so closely resembles the type that a separate description is 

 unnecessary. It differs from the type, however, in not having black 

 discal spots on the clypeus; in having the black baso-lateral borders 

 much reduced; in having the sides of the thorax and propodeum 

 somewhat more extensively maculated; in having a pair of yellow 

 spots on the posterior surface of the propodeum; in having the 

 discal and lateral spots separated from one another on all the 

 tergites except the fourth ; and in having the coxae maculated. The 

 sixth sternite has its apical portion wholly yellow. 



The wings of this species are almost hyaline. The pubescence on 

 thorax and propodeum is unusualh' dense, relatively long, and of 

 a decidedly browmish color. There is some variation among the 

 paratypes. On none of them do we find a pair of black spots on 

 the clypeus. On one male the lateral and discal spots are separate 

 on tergites 1-3, and on two of the females the lateral and discal 

 spots are separate on all the tergites. The baso-lateral black border 

 on the clypeus varies in extent but is never lacking. The extent 

 of the maculations on the side of the thorax and propodeum varies 

 on the different individuals. 



This species is very closely related to vulpina (Handlirsch). from 

 which it can be readily distinguished (1) by the maculations of the 

 abdomen, which are practically white in vulpina and are creamy 

 yellow in hrimneH; (2) by the pubescence on the propodeum. which 

 is decidedly white in vulpina and decidedly brownish in hrunneri^
