WILLIAMS: LARRID^ OF KANSAS. 123 



taken from those in Fox's "North American Larridse" (Proc. 

 Acad. Nat. Sci. Phil., 1893). These are usually abridged, ex- 

 cept in the case of new species, and often refer more particu- 

 larly to the Kansas specimens. 



No attempt has been made to cite much of the literature 

 relating either directly or indirectly to the Larridae. This is 

 largely because of the inaccessibility of many of these writ- 

 ings, chiefly those of Europe, which are very important, and 

 because of the limited scope of this paper. In the systematic 

 portion reference is made to the original descriptions, and very 

 frequently also to the best or more accessible diagnoses. The 

 drawings are original, often of camera lucida outline, and 

 where possible are made from the type specimen. 



In conclusion I desire to extend my thanks to the various 

 members of the Kansas University Entomological Survey who 

 assisted me in the field work; to the oflScers of the United 

 States National Museum, for the favors extended me while 

 there, especially to Mr. S. A. Rohwer, of that institution, for 

 the very efficient aid given me in identifying species, etc.; to 

 the Academy of Natural Sciences of Philadelphia, for similar 

 kindness, and in particular to Mr. Wm. J. Fox, for copying 

 portions of literature inaccessible to me, and for comparing 

 specimens ; to Prof. Myron H. Swenk, of Nebraska University, 

 for the loan of certain Larridse; to Mr. H. B. Hungerford, of 

 Kansas University, for criticizing the manuscript ; and finally 

 to Prof. S. J. Hunter, in whose department this work was 

 done, for many helpful suggestions and for his patience and 

 criticism in going over the manuscript.
