SOME NEW EUCERINE BEES FROM THE WEST. 
RY T. n. A. COCK.ERELL, BOULDER, COLr)RADO. 
Melissodes herricki, n. sp. 
$ Length about 13;^ mm., robust, black, densely covered above with short 
fulvous pubescence, very bright orange-fulvous on thorax; on abdomen thinner, 
showing the black shining surface through, but the hind margins of segments 2 to 
6 broadly testaceous, and covered by fulvous hair-bands; face, cheeks, pleura 
and ventral surface generally with white hair; legs also with white hair, but the 
knee-tufts ochreous, hair on outer side of tibiae slightly yellowish, and that of 
inner side of tarsi pale orange; small joints of tarsi ferruginous; spurs ferruginous- 
Eyes large, greyish-brown; facial quadrangle much longer than broad; clypeus 
light lemon yellow, the anterior edge ferruginous; labrum cream-color, densely 
covered with white hair; mandibles entirely black; antennae of only moderate 
length (about 7mm), black; flagellum brown-black beneath, with obscure lighter 
dots on the joints; tegulae ochraceous; wings dusky hyaline, nervures dark fus- 
cous; second submarginal cell broader than high, but by no means so long as 
first; second transverso-cubital nervure with a curious double curve; first r. n. 
joining second s. m. not far from its end; third s m. abruptly angled outwardly; 
apical plate of abdomen with the margins gently concave, not notched. 
9 Looks like the $ , but abdomen rather broader, and appearing entirely 
fulvous, the pubescence being thick and the tegument yellowish; hair of apex 
very bright orange-fulvous; hair of legs more decidedly fulvous-tinged, that on 
outer side of middle tibiae shining light fulvous, that on inner side of basal joint 
of hind tarsi ferruginous; scopa of hind legs fulvous-tinted, long and beautifully 
plumose; facial quadrangle about square; clypeus and labrum black, the hair of 
the latter tinged with yellowish; apical half of mandibles mainly fulvous, anten- 
nae dark, third joint longer than 4 + 5, flagellum slightly brownish beneath. The 
double curve of the second t. c. is as in the $ . 
Hah . — New Mexico ( H. Snoiii)\ no locality given, but the specimens are 
numbered 91 ( $ ) and 92 ( 9 ). Named afterthe late Dr. C. L. Herrick, in recog- 
nition of his important work on the geology and zoology of New Mexico, carried 
on with indefatigable zeal for many years in spite of poor health and other diffi- 
culties. Superficially, this fine insect looks just like M. townsendi CklL, but it is 
easily distinguished by the color of the antennae and of the hair of the scutel- 
lum. In the form and color of the abdomen the female M. herricki is like male 
M. iownseitdi.
