the mouth of Monroe canyon, in Sioux county, June 22, Igo, on 
Helianthus sp. (M. A. Carriker, Jr.). Seems to differ from the 
typical specimen in having yellow on the fourth dorsal abdominal 
segment.

A single male, taken at Glen, August 14, 1906 (L. Bruner). 
This specimen has only two black dots on the second: dorsal seg- 
ment in place of the usual band, and has four of the ventral seg- 
ments banded with black. I call it propinquus, although Hand- 
lirsch says it is identical with abdominalis. The presence or 
absence of the foveae in the suture separating the mesonotum 
from the scutellum, it seems to me, is a sufficient character for 
separating the two.

A single male, taken at West Point, June (L. Bruner). It has 
the second dorsal segment yellow apically instead of being en- 
tirely black as indicated in the description.

A single male from the above locality. The male has been 
hitherto undescribed, and differs from the description of the fe- 
male in having the entire basal abdominal segment yellow above, 
in having two reddish spots on the metathorax, and yellow bands 
on the remaining segments. These two species look very much 
alike, but may be readily separated by the characters given in the, 
table.
