80 CARABID.E. SYNUCHUS. 



in these individual specimens. It is rather smaller than mollis, 

 and has a very dissimilar form ; the head is both smaller and 

 narrower, the antenna? more robust, especially from the fifth 

 joint and upwards, in which respect it resembles microptents, 

 these are likewise more pubescent, and never in paler nor in less 

 mature individuals are they, as Mr. Haliday informs us, entirely 

 red, though sometimes one and sometimes two or three joints at 

 the base may be paler ; the thorax is more narrowed in front and 

 less narrowed behind than in mollis, and the basal fovese narrower 

 and more parallel to the sides ; the elytra are broader in front, 

 with their sides more parallel and not as in mollis more rounded 

 and dilated in the middle, so as to appear as in that insect 

 distinctly narrowed before and behind, the striae likewise are 

 deeper. 



This very interesting addition to the British fauna was dis- 

 covered by Mr. Haliday on the Irish mountains : " Slubh Donard, 

 Downshire, 2700 feet above the sea ; on Lugnaquilla, 3000 feet, 

 and other mountainous ranges in Wicklow, among the piled-up 

 stones, early in the summer, but later in the season they were 

 not to be found." A. H. H.
