The writer has not seen the type of this species altho type mate- 

 rial has been studied. Dr. Philip A. Munz has been kind enough to 

 furnish the writer with a list of the type specimens of Aliridae which 

 are found in the Pomona College collection. This list indicates that 

 most of the types are contained there of species described by Renter 

 from the material collected by Prof. C. F. Baker. Of seven speci- 

 mens from the type locality one is labeled "Camptobrochis" by Renter 

 but without specific name written out. This omission was probably 

 due to an oversight which was never corrected following the descrip- 

 tion of the species. 



No data are available regarding the food habits of the species, 

 altho the ]\Iay and September records indicate that the adults hibernate.
