Cerceris insolita Cress. 
Cresson, Proc. Ent. Soc. Phila., 5 : 129, 1865. 
One female from Tucson, Ariz., July (Bequaert). 
Cerceris solidaginis Boliw. 
Rohwer, Can. Ent., 1908: 323. 
This species, separated on males from femur -rub rum 
on having the enclosure with large punctures, not smooth 
in middle, and no pale lateral mark on propodeum. Of 
five females before me two have the stripe on propodeum, 
are larger, broader, three without the stripe are smaller, 
less broad, and therefore have a slightly less broad cly- 
peal process. In the numerous males most are without 
the stripe on propodeum, two with only a dot ; the sculp- 
ture of the enclosure in most of the specimens is more or 
less irregular. I doubt if it is a distinct species, but the 
name may be of use for a lower category. Specimens of 
each form were taken at Tempe on the same dates. 
Cerceris femur-rub rum Vier. & Ckll. 
Yiereck and Cockerell, Jour. N. Y. Ent. Soc., 12: 135, 
1904. 
No record from California, but since it is very common 
at Tempe, Arizona, it mav occur in southern California. 
It is structurally much like the eastern C. compacta, but 
much more yellow. 
Cerceris fidelis Vier. & Ckll. 
Yiereck and Cockerell, Jour. N. Y. Ent. Soc., 12: 132, 
1904. 
Have none from California, but it is so common at 
Tempe and Tucson, Arizona, it quite possibly occurs in 
southern California. 
Cerceris orphne sp. nov.
