ANTHOPHILUS MULTIMACULATUS Cameron. 



One female and six males from the Santa Barbara coast, June 1907. 



ANTHOPHILUS PACIFICUS (Cresson). 



Five males from Alameda Count}'^, California, July 1907; three 

 males from the Santa Barbara coast, June 1907. 



CERCERIS FINITIMA Cresson. 



Thirty-one males from the coast and two from the foothills of 

 Santa Barbara County, California. Specimens collected in June 

 and August 1907. 



CERCERIS CALIFORNICA Cresson. 



One male from Calaveras County, California, collected July, 1910, 

 by Blaisdell agrees fairly well with Cresson's description. 



LARROPSIS TENUICORNIS (Smith). 



A single male specimen from Alameda County, California, July, 

 1907, is not quite typical, as the striae on the propodeum curve 

 anteriorly. 



TACHYSPHEX TERMINATUS (Smith). 



One female and three males from Alameda County, California, 

 July, 1907; and one male from the foothills of Santa Barbara, 

 California, collected August, 1907. No differences between these and 

 New Jersey specimens were found. 



TACHYSPHEX GIFFARDI, new species. 



In Fox's Revision of the North American Larridae this species 

 traces to montanus Cresson, but differs in clypeal characters, color, 

 etc. From tarsatus Say, hitei Eohwer, and semirufus Cresson the 

 punctuation will distinguish. 



Female. — Length, 8 mm. Clypeus strongly convex, shining, with 

 large separate punctures, the anterior margin subtruncate, the lateral 

 angles not or but slightly produced; frons opaque, granular with dis- 

 tinct separate punctures in addition; above the anterior ocellus the 

 granulation is much finer and the punctures closer and better defined ; 

 the superior interocular line much more than half the inferior inter- 

 ocular line, greater than the length of antennal joints two plus three 

 but less than three plus four; antennae scarcely tapering, the third 

 and fourth joints subequal; scutum and scutellum shining, with dis- 

 tinct scattered punctures which are closer and finer on the scutum 

 anteriorly; dorsal aspect of the propodeum coarsely granular; meso- 

 plurae and sides of propodeum coriaceous; posterior face of the 

 propodeum transversely striated, the dorsal stria being more promi-
