336 On Insects from New Meaico, 
Euura salicis-nodus, Walsh. 
Hab. Vicinity of Las Vegas, N. M., fly emerging April 4 
(Mary Cooper). 
I have only a single fly, and that is headless; but I think 
the identity is reasonably certain, as the galls agree, and the 
willow is, I believe, the same species as that from which 
Walsh obtained his species. The colour of the galls is red. 
From these galls were also bred two females of a Prosopis 
which is probably a variety of P. mesille, but may prove 
distinct when the male is obtained. It lacks the clypeal 
mark of mesi/le, and yet has the form of that insect rather 
than of P. pygmea. 
Apide. 
Osmia fulgida, Cresson. 
Hab. Beulah, July 16, 1900 (7. D. A. & W. P. Ckil.). 
New to New Mexico. 
Osmia armaticeps, Cresson, var. sapellonis, var. n. 
9 .—Length 12 millim. 
Agrees with the description of armaticeps, except that the 
cheeks, instead of being “ sparsely and finely punctured,” are 
very strongly and quite closely punctured; and the meso- 
thorax, instead of being ‘sparsely punctured and polished,” 
is very strongly and densely punctured, the punctures being 
as close as it is possible for them to be. Probably a 
distinct species. 
Hab. Hill above Beulah, Aug. 19 (Ck77.). 
It has a superficial resemblance to Monumetha argentifrons. 
Celioxys Say?, Robertson. 
Hab. Las Vegas, at flowers of white hollyhock, July 10, 
1900, 1 2 (Ckil.). 
New to the local fauna. 
Monumetha argentifrons, Cresson. 
This species is usually called IZ, borealis, but the name 
argentifrons has priority of place. 
siderably in size. 
Hab. West Fork, Gila River, July 12, 9 (Townsend) ; 
Beulah, Aug. 16, &c. (W’. Porter). I have also both sexes 
from Olympia, Washington State, collected by Mr. Trevor 
Kincaid ; one of the males was collected July 3, on flowers of 
Epilobium spicatum. 
The female varies con-
