5. Black space in middle of first abdominal segment semilun- 
ar or broadly triangular. (Mesilla Valley.) . lunatus, Say. 
Black space in middle of first abdominal segment a trans- 
verse band, not triangular. (Santa Fe, Albuquerque, 
Mesilla Valley.) . . . occidentalism Cress.

large ones, . . . . . .7

produced and curved downwards, fifth abdominal seg-

concavus. Cress. 
Apex of 9 abdomen not at all truncate ; last ventral seg- 
ment broad, not produced beyond last dorsal ; fifth ab- 
dominal segment with a patch of light pubescence on 
each side. (Albuquerque.) . . robustusm Cress. 
8. Antennae wholly dark. (Mesilla, Aug. 14, at fls. of Heli~ 
anthus ciliaris.) . . texanus var. nigripes, n. var. 
Note. — What has been regarded as E. remigatus, Fabr., in New Mexico 
seems to be robustus. It is possible that the species recorded by Cresson as 
taken by Lewis many years ago, was true remigatus. 
Ericrocis. 
Appearance and ornaments much like Epeolus ; the yellowish-white 
hair-bands of abdomen, felted as in Epeolus, all broadly interrupt- 
ed ; third submarginal cell in J' about twice as broad as second, 
in 9 hardly broader than second. (Mesilla Park, April 29, 189S, 
the sexes together on flowers of CcEdalpinia falcaria var. stricta, C. 
M. Barber.) ....... lata, Cress. 
Note. — Although there is a striking difference in the venation of the two 
sexes, they certainly belong together. A single $ of E. lata was taken by Mr. 
A. P. Morse near Little Mountain, Mesilla Valley, July i, 1897. 
Melecta. 
Abdomen with brown spots and a brown patch on a white ground, the 
white due to pubescence ; size small ; flagellum very stout. (Me- 
silla Valley.) ..... maculata, Cress. 
Abdomen black, with clean-cut light bands, interrupted medially, i

Divide.) .... interrupta. Cress. 
Smaller, the bands white. (Santa Fe, Mesilla Valley.)
