THREE SPECIES OF COLEOPTERA NEW TO BRITAIN, 

 BY NORMAN H JOY, M.E.C.S., F.E.S. 



Dacne rowLEiii, sv- n. 

 Of the same size and shape as D. humerali.i, F., shining black, with head 

 thorax, antenna", and legs dark ferruginous; the thorax suffused with black, the 

 elytra with a spot at the shoulder reddish -yellow ; thorax and elytra punctured as 

 in D. humeralis, the thoi'ax with the lateral margins much broader, making the 

 anterior angles more prominent ; leirs distinctly longer an! more robust than in 

 D. humeralis and D. rufifrons. Length, 3 mm. 



In colour this species is somewhat intermediate between 

 D. humeralis and Z>. rwfxfrons, but the legs, and especially the 

 antennae, are darker than in either. In the structure of the thorax 

 it more nearly resembles D. humeralis, but the reflexed margins are 

 more than twice as broad as those of the best developed specimen 

 of the latter I can find. But besides these colour and structural 

 differences the present species differs considerably in habits from its 

 British allies. The latter are decidedly sluggish insects. They are 

 generally found in fungus or under bark, and when shaken out lie 

 " possum " for a short time and then walk slowly away. D. fowleri 

 is much more active. I found four specimens of it at Bradfield, 

 Berks, in June this year in a hole in a large oak log, where a rotten 

 branch had been broken off. I disturbed them out of the dry wood, 

 and when they fell down they rapidly ran off, so that I was only able 

 to capture tw^o of them. I did not for a moment suspect that my 

 captures belonged to this genus, their habits and general appearance 

 in life being so different from those of D. humeralis and D. rufifrons.
