quainted with. But as I feel great delicacy in differing 

 from such high authority as that of Dr. Burmeister, I have 

 thought it better to place it as the next species to Ceble- 

 brachys. Still the question arises, what is the Pediculus 

 Strigis of authors, if not the same as platyrhynchus ? is it 

 identical with the Docophorus Cursor, which is also found 

 on Owls, and to which the " Abdomine ovato albo, margine 

 pedibusque rubris," of Fabricius, would apply very well? 

 But here again Dr. Burmeister, the only author who enu- 

 merates this species, makes no reference to the synonyms 

 of preceding writers, with which he must necessarily be 

 familiar, and which would seem to imply that it was not 

 their Strigis.
