8 CALIFORNIA ACADEMY OF SCIENCES. 



Following the notes on distribution, etc., there 

 will be found descriptions of a considerable number of 

 the new species mentioned in the list. There are still 

 many others left undescribed, chiefly for the reason that 

 their proper definition would require a more extended 

 investigation than is now possible. A few allied spe- 

 cies from other parts of the country have also been 

 described. 



Finally, it is a pleasure to acknowledge the kind and 

 ready assistance of entomological friends in the prepa- 

 ration of the following pages, more particularly of my 

 fellow Californians, Messrs. Fenyes, Daggett, Fuchs, 

 Van Dyke, Rivers and Ricksecker. 



To Mr. Fuchs I am especially indebted for a careful 

 examination of the manuscript and the consequent 

 detection of a few errors and the addition of a number 

 of species based upon his own collection.
