hardly punctured, a tuft of fulvous hair just behind ocelli;, 

 hair of occiput whitish, of cheeks white ; antennae black ; facial 

 quadrangle longer than broad; hair of thorax very dense, 

 tinged with ochreous, and even with fulvous above ; tegulae 

 pale testaceous; wings slightly dusky; legs black, with mainly 

 black pubescence, but that on anterior femora behind yellow- 

 ish-white ; the abundant and coarse scopa of hind tibiae and 

 tarsi wholly black; abdomen black, practically nude, only the 

 first segment with pale pruinose pubescence. The pectoral 

 hair of thorax is variably sooty in this species, so C. foxi, 

 Friese, must be separated on the characters of the clypeus and 

 labrum, not those of the pubescence. 



Palm Spring, Cal., two collected by Dr. Davidson. Previ- 

 ously known from New Mexico. 



EMPHOROPSIS, Askmead. 

 Emphoropsis infemalis, (Dalla Torre) subsp. nov. trlstissima. 



Female ; length about 14 mm. ; black, robust, with the pubes- 

 cence entirely black, except a little reddish on hind part of 

 mesothorax, and dark reddish on inner side of basal joints of 

 tarsi ; facial quadrangle broader than long ; inner orbital mar- 

 gins straight ; clypeus coarsely rugoso-punctate ; labrum cov- 

 ered with black hair; pubescence of thorax and first segment 

 of abdomen dense, rest of abdomen rather shining and not 

 conspicuously pubescent ; tegulae very dark brown ; wings only 

 a little dusky; knee-plates of hind tibiae whitish with a large 

 reddish patch, very conspicuous; legs normal, hind tibiae and 

 tarsi more or less ferruginous. Lacks the light pubescence 

 seen in typical infemalis, which is from Nevada. 



Los Angeles, one, and Lancaster, Mohave Desert, one, both 

 collected by Dr. Davidson. 



E. infernaJis was described as an Anthophora, but Dr. Ash- 

 mead wrote me, some years ago, that it was an Emphoropsis. 



ANTHOPHORA, Latreille. 

 Anthophora crotchii, Cresson. 



Dr. Davidson obtained one at Banning ; I give a new descrip- 

 tion, that of Cresson being rather short. 



Male ; length about 16 mm. ; black ; head and thorax with 

 abundant yellowish pubescence ; that of abdomen more scanty,, 

 whitish basally, but erect and black on the third to sixth seg- 

 ments, the sixth fringed with whitish, and a light tuft on each 

 side of the apex ; eyes large, reddish when dry ; facial quad- 

 rangle considerably longer than broad, narrowest in the mid- 

 dle ; ocelli large, a prominent tuft of long ochreous hair just
