ON CHRYSOBOTHRIS CALIFORNICA AND ALLIES. 



By H. C. Fall, 

 Pasadena, Cal. 



In my List of the Coleoptera of Southern California reference is 

 made to the taking in the San Bernardino Mts. of a specimen of 

 Chrysobothris californica from its burrow in the dead twigs of Pinns 

 ponderosa. The identification was based on Horn's table and de- 

 scription and seemed satisfactory. A little later a second specimen 

 taken in the same region was identified for me by an eastern specialist 

 as californica. The two specimens looked much alike, and the identi- 

 cation was accepted without question. From time to time other 

 specimens were added to my series, until it began to take on a some- 

 what mixed appearance, and a recent critical examination has con- 

 vinced me that no less than three distinct species were involved. 

 To determine which was the real californica comparison was made 

 this past summer with the LeConte type at Cambridge. Imagine my 

 surprise at finding that neither one of the three was identical with 

 the type. One of my species proved to be caurina Horn (not quite 

 typical however), while the other two were new and will be described 

 in the present paper. 



Further investigation among the allied species revealed a condition 

 of affairs wholly unexpected. Notwithstanding the deliberate and 

 painstaking work of Horn in his treatment of this genus, errors of 

 such a nature exist in the table and descriptions of certain species 

 in this part of Group IV as to make it quite impossible for the 

 student correctly to identify his material thereby. Three species are 

 involved in these errors, which are briefly as follows:
