CARABIDJE. TARUS. 21 



ferruginous red from the base to about two-thirds its length. 

 Head faintly punctured behind, with an oblong rugose impression 

 on each side in front. Thorax cordate, finely rugose-punctate. 

 Elytra shorter and wider in proportion than in crepitans, 

 shoulders broader and more prominent, sides very little wider 

 behind the middle, obsoletely striated, interstices faintly punc- 

 tured ; body beneath entirely rusty red. Length 2-3 lines. 



This species is usually smaller than the smallest examples of 

 crepitans, and in form more delicate, and may at once be recog- 

 nized by an abbreviated red dash at the base of the suture. Its 

 claim to be admitted into our British fauna rests apparently on 

 very few examples ; the first recorded by Mr. Curtis as having 

 been captured by Dr. Leach in Devonshire ; a second reputed 

 to have been taken by the Rev. F. W. Hope at Southend; and 

 a third, in Mr. Stephens's collection, supposed to have been 

 found near Hastings. There are others in the collection of the 

 late Mr. Vigors, and in that of the Rev. A. Matthews (which 

 last were obtained from Mr. Vigors), said to have been captured 

 in Norfolk.
