48 COLEOPTERA. 



pressa ; from the former of which it differs by having its 

 prothorax more evidently punctured, with the central channel 

 only perceptible anteriorly ; the lateral fovese, also, are not so 

 deeply impressed, and those at the base of the elytra are 

 shorter. Apex of the abdomen concolorous. From A. im- 

 pressa it may be readily distinguished by its black colour 

 and evidently punctured abdomen.

 Taken last August in the Black Forest, Perthshire, by 

 Mr. D. Sharp ; who, I believe, also simultaneously deter- 

 mined it as L. analis. 



It differs from L. fumida in its superior size, reddish- 

 brown colour, semi-opaque surface, and more strongly and 

 coarsely punctate abdomen. The antennae are especially of a 

 clearer red colour, and the thorax larger and more quadrate. 

 In the male, moreover, the fifth and sixth segments of the 

 abdomen above have each a thin, long, mesial ridge ; that 

 on the fifth seo^ment extendino^ backwards from near the 

 apical margin for three-fourths of the length of the segment. 

 Each of these thin ridges is represented by a very minute 

 tubercle in L. fumida.

A single specimen was captured by the Rev. A. Matthews, 



many years since, in Oxfordshire.
