AND O? BRADLEYI CAMERON 
(HYMENOPTERA: VESPIDAE: EUMENINAE)*

Bohart (1965) treated the identity of 100 names of North Ameri- 
can Eumeninae described by Peter Cameron from 1905 to 1912. 
This paper established the synonymy of all but four of these names, 
and so solved many problems in the nomenclature of nearctic 
Eumeninae. During a recent visit to the British Museum, I studied 
the type specimens of two of the unrecognized species, and in the 
present work establish their synonymy. 
Euodynerus scudderi (Cameron, 1908) New Combination 
Odynerus scudderi Cameron, 1908: 196. $; locality not stated (British Museum). 
Odynerus discogaster Bequaert, 1939: 65. 9; “Mt. Diablo, Contra Costa Co., 1,500 to 
2,000 ft., CALIFORNIA” (Museum of Comparative Zoology). New Synonymy. 
Bohart (1965) stated in regard to this species: “Type location 
unknown; pseudotype $, Chimney Gulch, Colorado, BMNH 
#18.541, does not agree with original description.” In fact, it agrees 
with the original description perfectly, and I regard it as the true 
type. It bears a handwritten label “Chimney Gulch Col. 6/17/98”. 
The writing is identical to that on material of other Cameron species 
collected by Oslar and specifically referred to in the same paper. 
Cameron’s description did omit various details which he commonly 
included in other descriptions, such as the coloration of the legs, and 
the label data. But the details which he did report match the speci- 
men, and are sufficiently precise to dispell doubt. In particular, the 
features of the clypeus are convincing. Cameron stated (1908: p. 
197): “Clypeus distinctly longer than wide; in its centre is a black 
mark extending from top to bottom, the top square, from there it 
becomes gradually widened to the middle, then gradually narrowed 
to near the apex, which extends in a clearly separated angle; the
