the metathorax has four dull yellow spots. The band on first abdomi- 

 nal segment is ferruginous in the middle. This does not precisely 

 agree with either of the forms Mr. Robertson gets in Illinois; it seems 

 to fall between them. It does not agree with N. sulphurata, although 

 that w^as described from Georgia. N. luteola was originally described 

 from "Carolina," and I suspect that the Georgia specimens here de- 

 scribed may truly represent that species, the Illinois insect of Robert- 

 son being different; but this is at present little better than a guess. 



A female collected b}- Mr. Viereck at Clementon, N. J., May 22, 1898, 

 is genuine N. luteola as understood by Robertson, A couple of males 

 from Mr. Viereck, one marked Montgomery county. Pa., are referred 

 to N. luteola. Two males in the National Museum belong to A', luteo- 

 loides; one is from "N. 111." (Belfrage), the other from J. L. Zabriskie, 

 Nyack, N. Y. A d" hdeoloides is from Edge Hill, Pa., April 28, 1901 

 (Viereck). 



Nomada edwardsii, Cress. 



\'ariable in size. Females from Corvallis, Oregon, May and June 

 (Cordley), and Washington State (Coll. of Acad. Nat. Sci. Phila.) 

 lack the two yellow stripes on disk of mesothorax. The stripes are 

 present in a female from Silver Lake, Utah, July 14 {H. Skinner). 



Nomada xanthopMla, Ckll., var. pecosensis n. var. (n. sp.?). 



A female specimen was taken at the Kin Kale Ranch, Pecos, N. M., 

 June 26, 1903, by Wilmatte P. Cockerell. It has a good deal of resem- 

 blance in color and markings to A'', suavis, Cress., but it is by no means 

 the same. I refer it to xanthophila, because it looks like that species 

 and is from the same general region, but it differs from the type c? by 

 the microscopically tessellate rather than punctured abdomen, the 

 bright ferruginous stigma, the second submarginal cell conspicuously 

 narrowed above; first joint of labial palpi considerably longer than 

 the other three together, second considerably longer than the third and 

 fourth together; third antennal joint conspicuously longer than fourth. 

 <Jther characters, more likely to be merely sexual, are: Head rather 

 abundantly hairy, though the face is almost bare; supracl3q3eal mark 

 well-developed; scape yellow in front, otherwise ferruginous with a 

 black mark behind; antennae reaching scutellum; sides of metathorax 

 with very large yellow patches; pleura with a very large transverse 

 yellow patch, and a yellow spot beneath the wings, no ferruginous at 

 all; hind coxae yellow in front; base and apical margin of first abdomi- 

 nal segment black, the rest (a very broad band) yellow; no ferruginous 

 on second segment. The eyes are sage-green. From A^ superba this
