REPORT OF ENTOMOLOGIST. 79 
N. rhodoxantha differing in some slight details of color, has been taken 
by Dr. Graenicher at Milwaukee, Wisconsin, on June 3. 
Nomada (Xatifhidium) crawfordi, new species. 
9 ; length about 11 mm., another red species with entire and broad 
bright yellow bands on the abdomen, similar to the last, but the first 
segment has a round yellow spot on each side, instead of a band. The 
sides of the face broadly, the anterior edge of the clypeus, the labrum, 
the upper margin of prothorax, the tubercles, two spots on the tegulae, 
and four spots on the metathorax, are yellow. The ventral surface of 
the abdomen is mainly yellow beyond the first segment. The scape is 
suffused with yellow in front, the flagellum is strongly blackish above 
towards the end, but the extreme tip is red; the third antennal joint is a 
little shorter than the fourth; the second submarginal cell is broad above, 
the third much narrowed above, its outer margin strongly angled; the 
basal nervure is a short distance basad of the transverso-medial. 
It is distinguished from the various similar species thus: 
From N. dilucida by the mesothorax being entirely red except the 
narrow anterior border and the median band,which are black; by the scu¬ 
tellum being entirely red; by the metathorax having four yellow spots; 
by the strongly punctured tegulae; by the hind femora having a long- 
oval red mark clean-cut out of the blackish at the base behind; by the 
hind tibiae being entirely red, but the basal joint of the hind tarsi yel¬ 
low behind; and by the first abdominal segment being red,with a yellow 
spot on each side between two black spots. From N. rhodoxantha by the 
broader form, longer third antennal joint, duskier wings, and cpiite dif¬ 
ferent pattern of first abdominal segment. From N. morrisoni by the 
longer fourth antennal joint, peculiar color of flagellum, red scutellum, 
shape of third submarginal cell, etc. From N. placitensis by its larger 
size, yellow on face, much less black on thorax, etc. From N. zebrata 
by the proportions of the antennal joints, red scutellum, etc. From N. 
citrina v. rufula by the red pleura and scutellum, the color of the flagel¬ 
lum, the absence of a yellow spot at the apex of the posterior femora, 
etc. The yellow of the legs is practically confined to the hind tarsi and 
front knees. 
One specimen; Virginia Dale, Colorado, June 20, 1901, F. C. 
Bishopp, collector. N. crawfordi is named after Mr. J. C. Craw¬ 
ford, Jr., in recognition of his work on bees. 
Mcirsda (Xanfhidium) ccNinsiana, new species. 
Two $s taken by S. A. Johnson, Fort Collins, Colorado, May 
11 and 20, 1903. One from wild plum. I had at first considered 
this a variety of N. crawfordi , but it may be kept separate for the 
present, at any rate. It differs from crawfordi thus: A trifle 
smaller; no yellow whatever on head or thorax; middle of front 
black, with a red spot in front of anterior ocellus; flagellum red; 
apical part not blackened; thorax more hairy; tegulse entirely red; 
third submarginal cell nearly or not far from as broad above as 
second; basal nervure more basad of transverso-medial; legs with¬ 
out yellow, except a small obscure spot at base of anterior and 
middle tibiae; hind femora red, with a broad black stripe behind, 
not reaching either end, and on it a band of short yellowish hair; 
hind coxae with much black (only a little in crawfordi ); base and 
apical margin of first abdominal segment black; pygidial plate nar¬ 
rower, venter ferruginous marked with yellow and black.
