Celia californica Zimm. loc. cit. 



Found in every part of California; the large specimens were taken along the 

 Gila river, and at Tucson, in Sonora. They do not differ appreciably, although 

 so large as almost to indicate another species, immature specimens occur with 

 the feet and under surface of a uniform brownish red color.

 a medio antrorsum angustato, lateribus rotundatis postice deplanatis, basi 

 punctata depressa, utrinque bifoveata, fovea externa maiore ; elytris thorace 

 paulo latioribus, striis tenuibus punctatis postice baud profundioribus, pedibus

Isophurus terrestris Lee. Ann. Lye. Nat. Hist. 4, 358.

 surface of the bodv is reddish brown. Closely related to the next species, but 

 is broader in form and has deeper elytral striae.

Russian America; two females sent to me by Baron Chaudoir, under the 

 names above cited, but between which I can perceive no difference. A male 

 sent by Mr. Motschulsky as C. relucens, has the thorax less transverse, with 

 the posterior angles rectangular, and the elytra shining.
