This well marked European species is very common in the western 

 part of the United States, from about the Great Plains, and in 

 Canada extends much farther east. I identified the species by 

 Stein's recent paper and also by careful comparison with a pair 

 from Europe identified by Professor Bezzi. The genitalia of both 

 sexes were compared. 



The species is the only one having the hind tibia villous on the 

 flexor side in the male and also having in the same sex a very 

 characteristic structure of the front basitarsus, whicli is concave on 

 the outer side before the middle and considerably longer than usual. 

 The species is like nigra in having only one large lateral pair of 

 bristles on the scutellum and a small apical pair. It has the abdomen 

 more broadly red than any other species, at least on the average, the 

 second i:)rincipal segment being usually without any black color. 

 It was this peculiarity which led me to suspect that calif omica Bigot 

 is the same species. J. E. Collin kindly examined Bigot's type with 

 reference to some of the points and his statements seem to prove 

 that my surmise Avas correct. 



The venter is silvery pollinose next the eye, and the parafrontal 

 and parafacial are also; the latter is rather wide, almost twice as 

 wide as the slender third antennal joint. The antennae are more or 

 less red from the base to the vicinity of the arista. The sides of the 

 thorax are silvery pollinose up the posthumeral bristle and there is 

 a very distinct narrow silvery median stripe reaching about to the 

 suture. The second principal segment of the abdomen in the male 

 has on the under side next to the median line two or three small 

 appressed bristles on each side on the hind corner of the tergite.
