 broad, plane, and smootli, the seventh distinctly carinate 

 behind. 



There is but one species like this — T. marginalis, no. 1329. 

 It has a more transverse thorax ; the humeral angles are 

 more rounded, so that tlie base of the thorax seems as wide, 

 or almost as wide, as they are. The elytral channels and 

 margins are wider ; the thoracic dorsal groove is deeper, and 

 the other sculpture differs, the sutural striaj only of the elytra 

 attain the apex, the others becoming obsolete there j it has 

 two ocular setse. 



In 7\ carhonarius there is but one seta, placed close to the 

 inner and back part of each eye, and this seems to arise from 

 a minute swelling instead of a distinct puncture. The pos- 

 terior tibiae are slightly arched. In T. marginalis the hind 

 margins of the thorax are thickened and flattened near the 

 posterior angles.

j I do not propose to follow Dr. Kertesz (' Catalogus Dipterorum 

 hucuaque Descriptonim,' vol. iii., Budapestini, 1908, p. 201) in adopting 

 as the designation of this well-known genus the name C/iri/sozoncr , Mg. 

 (' Nouvelle Classification,' 23. 34, 1800), which, although actually 

 possessing three years' priority over Hcematojwta, was, so to speak, 5^///- 

 horn, i. e. never entered into common use, and for more than a century 

 has remained buried in oblivion. This is surely a typical instance of a 

 case in wliich the rules of strict priority should be disregarded in favour 

 of expedienc\- and common-sense !
