P. F. Frank (CMN), R. A. Cannings (RBCM), and R. L. Hoffman 
(VMNH); my colleague W. A. Shear provided specimens in his private 
holdings. Figures 2, 31-33 were prepared by R. G. Kuhler, NCSM 
scientific illustrator, who assisted with the other illustrations. I thank 
V. F. Lee & B. W. Rogers, for localiting obscure California localities; 
S. Bauer, for segment counts and measurements; C. Wood, for word 
processing; B. Randall-Schadel, for use of a compound microscope; 
and A. R. Hardy, for information about John Lawrence LeConte.
