NO. 1806. J3EES IN THE NATIONAL MUSEUM. l.—COCKERELL. 655 



third antennal joint is always distinctly longer than the fourth, not 

 about equal as in inorrisoni. Superficially, the insect is like N. lama- 

 rensis, but it is a Holonomada, and the metathorax, except the black 

 (or black and red) basal area, is nearly all yellow. The basal area is 

 considerably smaller than in N. zehrata. The pleura has a variable 

 amount of yellow, and the mesothorax is always red with a single 

 black band. The face is red, variably suffused with yellow. 



Male. — Length 11 or 12 mm.; similar to N. affahilis, but obscure 

 mark at top of eyes red; flagellum red, with its first six joints black 

 above, the sides of the black sharply defined; wings yellowish; last 

 abdominal segment (like the others) with a j^ellow band, the abdomi- 

 nal bands not narrowed in middle, except the first two slightly. The 

 scape is thick, entirely yellow beneath. The yellow on the pleura is 

 broadly margined with ferruginous. In my table '^ this runs to 

 affahilis, except that the legs must be described as red, with yellow 

 and black markings. The second s. m. is very large, and receives the 

 first r. n. beyond the middle. 



Habitat. — Dallas, Texas. Eight females (the type is a female), six 

 from dewberry fiowers, April 9, 1906 (Crawford and Pratt) ; one from 

 blackberry, March 21, 1907 (Bishopp). One male at Cercis cana- 

 densis, March 22, 1909 (Bishopp). 



Type.— Cat. No. 13434, U.S.N.M. 



NOMADA (XANXmDIUM) LUTEOLA BISHOPPI, new subspecies. 



Female. — Third antennal joint almost or quite as long as fourth; 

 flagellum clear red, dusky at the sutures above; mesothorax red 

 banded with yellow, varying to reddish-black, with the median bands 

 abbreviated; yellow of metathorax covering sides of basal area; 

 pleura with a large yellow patch. This looks much like iY. affahilis 

 dallasensis, but is smaller, with the third antennal joint evidently 

 shorter, and the mesothorax with yellow stripes. 



Ilahitat. — Dallas, Texas, type at flowers of wild plum, March 16, 

 1907 (Bishopp); also one at flowers of dewberry, April 9, 1906 (J. C. 

 Crawford). Dark variety, Monroe, Louisiana, March 4, 1908, at 

 Cratsegus flowers (R. A. Cushman). 



A male N. luteoloides Robertson was taken at Logansport, Louisiana, 

 March 24 (E. S. Tucker). I will also take occasion to record N. 

 luteola Olivier from Helena, Montana, August 6, 1909 (Mann). 



Type.—Csit. No. 13435, U.S.N.M. 



The only male Xanthidium from Texas before me was taken by F. 

 C. Bishopp at Wolfe City, at flowers of plum, March 5, 1908. It is N. 

 luteoloides, but the anterior tibiae have a large black mark behind.
