74 ADEPHAGA. [Cilia. 



small, eyes prominent, antennse as a rule red, sometimes however 

 brownish with the basal joints lighter ; thorax much broader than 

 long, sides moderately rounded in front, almost stKiight towards base, 

 in some specimens slightly contracted, posterior angles more or less 

 sharp right angles, doi^al furrow distinct, base very variably punctured, 

 sometimes almost impunctate, with two deep and rather irregular 

 foveae on each side ; elytra at base slightly broader than base of thorax, 

 finely striated, the strise more or less punctured, hut sometimes so 

 obsoletely that the punctures are almost invisible, intei-stices flat, 

 underside dark brown, black, or reddish ; legs lighter or darker brown 

 red ; in minor points the specimens vary considerably. L. 5-7 mm. 



A mouiitaiu species ; very local iu the Dee district of Scotland ; it occurs on the 

 Continent iu mouutain districts from Lapland to the Caucasus, often at very con- 

 siderable elevations. I have before uie Dr. Sharp's large and fine series from Rrae- 

 luar, which shows many of the slight variations above alluded to ; none of the speci- 

 mens, however, are as metallic as a Continental specimen sent me by Herr lleitter,
