punctures very irregular, but leaving a good deal of shining surface; an* 
tennas red, third joint longer than fourth, flagellum blackish above; teg 
ulae yellow with a ferruginous spot and rim; wings dusky, the apex 
very dark; stigma orange-ferruginous; nervures fuscous; second sub- 
marginal cell large and nearly square, receiving the recurrent nervure 
just beyond the middle ;basal nervure meeting transverse-medial; ventral 
surface of abdomen without yellow markings; legs red, hind coxae with a 
yellow spot, hind tibiae with some yellow; anterior coxae with red spines. 
Apical plate deeply notched. 
One from Lamar, Colorado, June 17, 1900, (E. D. Ball, col¬ 
lector). This cannot be the $ of N. wheeleri , as that species has 
the submarginal cells quite different; in wheeleri the third sub¬ 
marginal cell is at least as broad above as the second, in lamaren¬ 
sis the second is rather more than twice as broad above as the 
third. The wings are much darker in lamarensis that in wheeleri . 
N. lamarensis resembles N. crassula in the very coarsely punc¬ 
tured mesothorax, and also in build, but differs in its red color, 
more strongly (indeed very strongly) bilobed scutellum, presence 
of a supraclypeal mark, etc. 
Nomada (Micronomaiia) ulderi, new species. 
c?; length about 7 k mm.; similar to N. vegana but more robust, the 
abdomen of spherical form, after the manner of N. erigeronis ; markings 
light primrose-yellow (deep yellow in vegana ), similar to those of vegana, 
but the labrum is entirely light red, the scape has only a yellow shade, 
and the metathorax is wholly without yellow marks; the mesothorax is 
densely punctured,more densely and coarsely than in vegana] ground-color 
of head and thorax black, but middle of mandibles red, a small red spot 
beneath the wings, and a red patch above middle and hind coxae; anten¬ 
nae red, scape and basal part of flagellum blackened above, the black not 
ending abruptly; tegulae primrose-yellow, with hyaline spot and margins; 
wings clear, with very dark apex; stigma ferruginous, nervures piceous, 
second marginal cell nearly square, and receiving the recurrent nervure 
very near the middle; in one wing of the type the first recurrent nervure 
is divided at the end,forming an areolet under the second submarginal cell; 
basal nervure meeting transverse-medial, and third antennal joint longer 
than fourth, as usual in Micronomada', spines on anterior coxae red and 
very long; legs red, anterior tibiae with alight yellow stripe in front, hind 
coxae with a yellow mark; there is a yellowish spot at the apex of each 
femur, and at the end of the hind tibia; abdomen dark brown above, clear 
red on first segment, beneath dark ferruginous, with linear yellowish 
markings; above, the first segment shows abroad primrose-yellow band, 
the second an extremely broad band, narrower in the middle, and the 
others bands which are hidden by the retraction of the segments; apical 
plate strongly notched. 
One from Fort Collins, Colorado, August 18, 1900, (E. S. G. 
Titus, collector). Named after Dr. Uhler, who was one of the first 
to collect species of No mad a in Colorado. 
Nomada (Holonomada) grandis, Cresson. 
One marked Colorado 2509, taken in the foothills near Fort 
Collins, May 26, by C. P. Gillette. This differs from N. magnidca 
in the venation, but otherwise they are practically the same. I 
do not know whether the differential character, which in the case of 
Gnathias is certainly subgeneric, can here be only varietal.
