Legs black ; bases of the legs provided with coarse hairs. Female. 

 This species received from California by Mr. Wosnessenski. 



Radoszkowski also gave a colored figure of this species. The figure 

 shows the thorax to be distinctly longer than broad, and the pubes- 

 cence of the head, thorax above, and abdomen above, yellow. 



Cresson (1865) published a description in English as that of 

 califomica^ and this rather than the original description has stood 

 as the basis for the identification of this species since that time. 

 Obviously Cresson's description is not a translation of the one pub- 

 lished by Radoszkowski since it neither agrees with the latter nor 

 with the published figure. Apparently Cresson's description is that 

 of a female fulvohirta which he misidentified as calif ornica. This 

 appears to be true, because he writes that " the thorax is short, broad 

 ovate when viewed from above," which agrees with fulvohirta very 

 well, but which does not agree with the published figure of cali- 

 f ornica, which shows the thorax to be distinctly longer than broad. 

 None of the species known from California conform to Cresson's 

 description; on the other hand, he states that his specimens are from 

 Colorado territory, and the only species that agrees with his de- 

 scription from that region is fulvohirta, which is not known from 

 California. 



The type of this species appears from the original article to be in 

 the collection of the St. Petersburg Academy of Science and I have 

 been unable to examine it. It is believed, however, that the speci- 

 mens here designated as calif ornica are the true calif ornica for the 

 following reasons: The specimens are all from California; the 

 thorax is longer than broad, and the pubescence above yellow, as indi- 

 cated in Radoszkowski's figure; several of the specimens also have 

 the yellow pubescent area of the abdomen above cordate at the base, 

 a character mentioned in the original Russian description and indi- 

 cated very plainly in the figure. 



The following is a description of the species as it is understood 

 here : 



Female. — Black; front, vertex, thorax above, and abdomen above 

 from base of second tergite clothed with long, erect, yellow 

 pubescence. Length, 9-5 mm. 



Head very dark mahogany red, almost black; mandibles acute at 

 the apex, unidentate within at a point about one-third their length 

 from the apex; clypeal fringe of long, dark hairs; scape closely 

 punctured, sparsely clothed with short, coarse pubescence; first seg- 

 ment of the flagelhim not twice as long as its own width at the apex ; 

 a distinct curved carina extending from the antennal tubercles to the 

 margins of the eyes; front and vertex with very large, confluent 

 punctures, clothed with erect and recumbent, long yellow pubescence,
