I have taken this species upon the Long-eared Owl (Otus 

 vulgaris), and received it from the Rev. L. Jenyns, and my 

 brother, who found it upon the Short eared Owl (Otus Bra- 

 chyotos) . I should have considered this species as the Pedi- 

 culus Strigis of Fabr. Stew. &c. had not Dr. Burmeister 

 remained silent upon the subject, and makes no reference 

 to preceding writers for synonyms, while Mr. Stephens in 

 his Catalogue of British Insects quotes the P. Strigis, as 

 synonymous with Nitzsch's Platyrhynchus, and Scopoli's 

 Hcematopus, vide page 95.
