DISTRIBUTION

 "type pimalas Wickham Mss. name'' (H. F. Wickham). Catalina Springs, 

 May 5 (Hubbard and Schwarz). Sabino Canyon, April 26, 1919 (G. Hofer). 

 Nogales, Santa Cruz County, October 2, 1906 (F. W. Nunenmacher). Palmer- 

 lee, Cochise County, August 10 (C. Schaeffer). Prescott (Mason collection). 



California: Kernville, May 14, 1930; Riverside County (B. G. Linsley). Hot 

 Springs, Tulare County, July 5, 1925 (E. R. Leach). Mill Creek, 5,200 to 

 5,500 feet elevation, San Bernardino Mountains, August 28, 1919 (Rehn and 

 Hebard). 



Lower California: Santa Rosa and San Felipe (Gustav Beyer). San Jose del 

 Cabo (Linsley collection). El Marmol, June 18, 1938 ( Michelbacher and 

 Ross). Sierra El Chinche, 2,000 feet elevation, cotype (Academy of Natural 

 Sciences of Philadelphia). 



Also recorded in the literature as follows : 



Arizona: Huachuca Mountains, July (Chamberlin 1926). 



California: Pasadena, July 14; Monica (Fall 1901). Palm Springs and Tulare 

 (Chamberlin 1926). 



Hosts. — Chamberlin (1926) gives the host as coast live oak {Quercus 

 agrifolia Nee). Specimens in the United States National Museum col- 

 lection are labeled as having been collected at Catalina Springs, Ariz., 

 by Hubbard and Schwarz at the roots of senna {Cassia covesii Gray), 

 and on the same plant at Sabino Canyon, Ariz., by George Hofer. 



There is considerable variation in the coloration and violaceous 

 markings on the elytra in this species. The color on the dorsal surface 

 of the body varies from bronzy green to violaceous blue, and the mark- 

 ings on the elytra are usually separated, sometimes joined to one an- 

 other along the sutural margins, and occasionally a specimen is found 

 in which the violaceous-black spot covers the greater part of the apical 

 region. In a few examples the pronotum is widest near the apex, with 

 the sides converging posteriorly, and the surface is more or less rugose. 

 A series of specimens from San Felipe and Santa Rosa from the Beyer 

 Collection have the pronotum more or less rugose, bright green, and 

 the elytra violaceous blue. The length is from 7 to 9.5 mm. 



This species was described by Horn from females and he gives the 

 type localities as Sierra El Chinche (2,000 feet) and San Jose del Cabo, 

 Lower California. Chamberlin (1926) gives the type locality as Sierra 

 El Chinche, but the type series in the California Academy of Sciences 

 consists of two specimens, both labeled "San Jose del Cabo, Lower 

 California," of which type No. 21 is the lectotype. A cotype, No. 3448, 

 in the Academy of Natural Sciences of Philadelphia, labeled with a 

 silver disk, is probably the specimen from Sierra El Chinche mentioned 

 by Horn.
