distinct little species, related to N. verecunda Cresson, but easily 
known by its creamy-white markings. The general appearance is 
suggestive of N. vierecki Ckll., but that has red legs. I wished to 
name this after its discoverer, but there is already a Nomada manni 
Morawitz. 
Nomada semisuavis sp. nov. . 
o. Length about 9 mm.; black and bright lemon yellow; the anterior coxe 
with long spines; third antennal joint much longer than fourth; b. n. 
meeting t. m. Almost exactly like NV. suavis Cresson, and possibly 
only a race or variety, but having the following distinctive characters: 
Scape swollen; lateral face-marks broader above; no black between 
lateral and supraclypeal marks; second s. m. narrower, receiving the 
first r. n. at its middle; yellow patch on pleura very large (fully 
twice as large as in suavis); legs seen from in front entirely yellow, 
anterior and middle femora with a black band behind, middle tibie 
with a black mark behind, hind femora almost entirely black behind, 
their tibize with a large black longitudinal band; last joint of hind 
tarsi bright ferruginous; apical plate of abdomen strongly and sharply 
notched (entire in suavis). N. suavis has been referred (Canad. 
Entom., 1905, p. 283) to Holonomada, but it belongs with the new 
species in the subgenus Micronomada. Both have in the male a pair 
of large yellow patches on the metathorax; Cresson’s supposed male 
of NV. suavis, without these marks, was probably VV. formula Viereck.

Nomada civilis spokanensis subsp. nov. 
9. Length about 114% mm.; similar to the Corvallis, Oregon, form of NV. 
civilis, but differing as follows: Scape wholly light red; tegule red- 
dish (instead of yellow); mark on pleura suffused with red, and re- 
duced, its posterior lobe obsolete or almost; yellow on scutellum re- 
duced, with a median black line; metathoracic marks reddish, very 
small; yellow of legs mainly replaced by red; apical half of first 
abdominal segment red, with a small obscure yellowish spot on each 
extreme side; second and third segments very broadly red in the 
middle. The nervures and stigma are bright ferruginous, and the 
second submarginal cell has the characteristic broad form, with the 
r. n, joining it beyond the middle. (The venation indicates its re- 
lationship with JV. civilis, and distinctness from the rather similar NV. 
vicinalis aldrichi Ckll.) 
Compared with the Colorado form of N. civilis it is still more dis- 
tinct, being much larger, with the bases of the abdominal segments
