CARABID.E. HARPALUS. 145 



angles slightly prominent, sides rather narrowed in front, then 

 rounded as far as the middle, from whence they are obliquely 

 sloped to the posterior angles which are nearly rectangular, but 

 the apex of the angle itself is somewhat obtuse, disk convex, trans- 

 versely wrinkled, the dorsal furrow abbreviated before and behind, 

 and terminating at both extremities in a distinct impression, the 

 base and basal angles punctured, and with a large shallow 

 roughly punctured fovea on each side about midway between 

 the dorsal furrow and the hinder angles. Elytra oblong, broader 

 than the thorax, sides scarcely rounded, apex obliquely sinuated, 

 convex, deeply striated, the margin with a series of coarse impres- 

 sions below the shoulders and before the apex ; legs pitchy with 

 the tarsi always and the tibia? occasionally ferruginous red. 

 Length 5| lines. 



Four or five examples of this species were captured by 

 Mr. Wollaston, in May 1852, at Slapton Ley/Devonshire; and 

 as I have not been able to identify it with any recorded species, 

 I have named it after the captor.

 on each side between the eyes and a transverse line in front ; 

 palpi and antennse testaceous red. Thorax nearly quadrate, 

 sides slightly rounded and widest in the middle, posterior angles 

 right angles, disk shining, transversely wrinkled, dorsal line 

 abbreviated in front, base with a broad rugose fovea on each 

 side, the fovese and the entire base being also thickly punctured.

Erichson informs us that he has seen in the Fabrician collec- 

 tion a ? of this insect placed as C. discoideus and that C. Petiffii, 

 D ufts., and H. perplexus, Gyll., are the ? , but H. Petiffii, Sturm, 

 the S of the same species. The Fabrician name must therefore 

 be adopted. H. differ of the Stephensian cabinet also must be
