a genus, which he calls Cervophthirhis, foi: a very closely re- 

 lated, if indeed not the same, species taken from Cerviis tar- 

 andns in Sweden. 



This genus differs from Linognathus only in the sharp pos- 

 terior-lateral angles of the head and in the presence of but one 

 row of hairs on each abdominal segment. I have available for 

 study six species of Linognathus and have concluded from 



Cervophthirhis crassicornis (N.). 

 Female. ( Drawing made from specimen (Above) Genitalia of male. Only the 



which has been cleared in caustic potash.) more heavily chitinized parts are shown.
