California (San Pedro, Los Angeles Co. 2). 



This species somewhat resembles the smaller forms of gi'ossus, 

 but mav I)e known by the broadly rounded clypeal angles, these 

 being narrowly rounded and distinctly produced anteriorly in that 

 species. 



C. ciliatus Esch. — This species is very abundant about San 

 Francisco. The series of thirty s])ecimens before me indicates but 

 slight variability excejjt in size, the specimens ranging- from 4.8 to 

 8.0 mm. in lenjith. 



Larva. 



The following description will serve for the identification of the 

 larva of Co'lus ciliatus. The specimens upon which the descrip- 

 tion is based were found in 

 a small sandy tract, in which 

 the imago was more than 

 usually plentiful, and un- 

 doubtedly represent the true 

 larva, ^ 



Body very elongate, slender, 

 cylindrical. Surface shining, 

 having a few very long fine set?e, 

 herissate with stilf fulvous set.ie 

 at the apex and sides of the head, 

 and beneath the latter and tlie 

 thoracic segments. Integuments 

 coriaceous, pale luteo-testaceous ; 

 head, protliorax and anal seg- 

 ment subcorneous, darker, rufo- 

 testaceous. 



Head as wide as the prothorax, 

 as long as wide. Post-epistomal 

 region slightly wider than long ; 

 sides parallel, nearly straight ;
