Cervophthirius crassicornis (N.) (Anoplura). 



By G. F. Ferris, Stanford University, California. 



Through the kindness of Professor W. B. Herms, of the 

 University of California, the Department of Entomology of 

 Stanford University has recently received some specimens of 

 an Anopluran from the black-tailed deer, Odocoilcus colum-

 ery of the species in North America being a matter of some 

 interest, I had prepared a short paper for publication and was 

 on the point of sending this to press when there came to hand 

 a paper which necessitates an entire readjustment of my own. 



The description and figure given by Giebel leave much to be 

 desired, but there are certain peculiarities about the species 

 that could not well be overlooked and the identification is rea- 

 sonably certain. The species has nothing to do with Haemato- 

 pinus and I regard it merely as a rather peculiar member of 

 the genus Linognathus. However, Mjoberg (Entomologisk 

 Tidskrift, Vol. 36, pt. 2-4, p.^ 282, Dec, 1915) has established
