COLEOPTERA OF SOUTHERN CALIFORNIA. 161 



Mountains, July; Pomona, September; Pasadena, June: 

 densus is credited by its describer to " California." A 

 single example of an uiidescribed species was taken in 

 the San Bernardino Mountains. 



TENEBRIONID.E. 



Craniotus. According to Mr. Fuchs, a specimen of 

 pubescens was secured by Dr. Blaisdell from near Val- 

 lecito, San Diego County. 



Edrotes. E. ventricosus is not uncommon on the Col- 

 orado Desert; I have taken it under stones at Palm 

 Springs, on the western border of the desert, in April. 

 With typical specimens of ventricosus occurred others of 

 duller surface lustre, with coarser punctuation and 

 pubescence less evidently condensed in lines along the 

 elytra; these Dr. Horn considered as mere varieties of 

 ventricosus, and if his opinion is well founded probably 

 nitidus, described from the Mojave Desert, should be 

 similarly disposed of. 



Triorophus. T. punctatus was described from a single 

 dead specimen found at Vallecito: Icevis is common 

 throughout the Colorado Desert: subpubescens , Antelope 

 Valley, Los Angeles County. 



Stibia. 8. ovipennis and 8. maritima both occur only 

 near San Diego, so far as is known. According to Dr. 

 Blaisdell, the former "inhabits the seashore and is 

 found beneath the beach-berry (Mesembryanthemum 

 cequilatevale) growing upon the sand-dunes," while mar- 

 itima inhabits the Coronado peninsula, and is not con- 

 fined to the seashore. 



Auchmobius. A. sublcevis is widely diffused in Cali- 

 fornia, but everywhere very rare; I have taken a single 



1 * September 21, 1901.
