146 CALIFORNIA ACADEMY OF SCIENCES. 



Tragidion. T. annulatum, Pasadena, June; Pomona, 

 September; San Bernardino Mountains (Van Dyke); 

 Santa Monica (Albright); rare. T. armatum has been 

 taken at Newhall (Van Dyke), while sucking sap from 

 stalks of flowering Yucca ivhipplei. 



Purpuricenus. P. dimidiatus, northern California. 



Metaleptus. M. angulatus, "So. Gal.;" doubtless 

 from the southeastern region. 



Amannus. A. pectoralis, Yurna (Le Conte.) 

 Batyle. B. suturalis, San Diego County (Fuchs). 



Oxoplus. 0. jocosus occurs rather rarely in the foot- 

 hill canons near Pomona; found flying by day along the 

 streams. 



Crossidius. C. hirtipes, C. ater, C. testaceus, and C. 

 punctatus bear Californiaii labels in one collection or 

 another, but with the exception of testaceus, which, 

 according to Fuchs, has been taken in San Diego County, 

 I have not been able to obtain exact localities. There is 

 not much doubt, however, that they occur only in the 

 eastern and southeastern portions of the State. 



Ischnonemis. 7. bivittatus, Indio (Van Dyke). 



Stenosphenus. S. debilis, several examples, beaten 

 from willows at Yuma, July. 



Cyllene. C. antennatus, common in the desert and 

 along the Colorado River; breeds in mesquite: crinicornis 

 also occurs in the southeast. 



Calloides. C. lorquinii, Mt. Lowe (Los Angeles 

 County), one example; Lower Soda Springs, Siskiyou 

 County, July (Van Dyke). 



Clytus. C. lanifer, Santa Barbara; more frequent 

 farther north.
