The catalogue of Dr. v. Dalla Torre unfortunately ignores 

 Dahlbom's publication of the name Homonotus in 1843. But atten- 

 tion has been called to it by Stein first, and again by F. F. Kohl ; 

 and the name Hoimonotus, Dhb., is restored in its original sense 

 for the present species by the most recent writer on the subject, 

 Dr. O. Sustera (Wien, 1912).

EUTHBIPS TAMICOLA, A NEW SPECIES OF THYSANOPTERA 



FROM THE FLOWEES OF THE BLACK BRYONY. 



BY RICHARD S. BAGNALL, F.L.S., F.E.S. 



One afternoon towards the end of June I found an ordinary 

 looking black Thrips, with a white band at the base of wings, in some 

 numbers, in the minute flowers of the Black Bryony (Tamus communis) 

 in the hedge-side near Yarnton, Oxon. I did not attach much im- 

 portance to this capture, but upon examination on my return home 

 it turned out to be a new and distinct species of Euthrips (AnajJw- 

 thrvps), which I describe below. The following evening I cycled along 

 several country roads and lanes in the neighbourhood of Oxford (in 

 the two counties) and took the same Thrips in the flowers wherever 

 the plant was found.
