nor tlie shape of the thorax or of its posterior angles can be depended 

 upon, aiul the other species, occasionally at any rate, have larger punc- 

 tures in the interstices. Dr. Sharp, in his collection, has not attempted 

 to assign his numerous specimens to either of the species, but has series 

 numbered from 1 to 7 containing varieties that lead gradually from near 

 cordatas to the most extreme rufihcirbis ; there are one or two inter- 

 mediate specimens which it would be perfectly impossible to assign to 

 either species. It seems extremely probable that H. rufibarbis, H. jninc- 

 ticollis, and H. parallelus will eventually be regarded as one variable 

 species. (For notes on the doubtful species of Oj^honus, &c., sec Ent. 

 Mo. Mag. xxii. 172.) 



(Sub-Gen. ii. Pseudophonus, !Mots.) 



I. Posterior angles of thorax sharp and projecting ; episterna of 



metathorax punctured H. ECFICORXIS, F. 



II. Posterior angles of thorax blunt ; episterna of metathorax 



smooth H. OEISETT3, Panz. 



K. ruficornis, F. Oblong, head and thorax black, somewhat shin- 

 ing, the latter thickly punctured at sides, disc almost smooth, posterior 

 angles sharp, projecting, somewhat acute ; elytra very dull, covered with 

 fine close punctuation between stripe, clothed entirely with a faie short 

 greyish-golden pubescence ; legs red. L. 12-15 mm. 



Common and generally distributed throughout the kingdom as far north as the 

 Moray district ; it does not, however, appear to occur in the extreme north of Scothind 

 as far as is known at present. 



K. griseus, Panz. Very like the preceding, of which it has often 

 been considered a variety, but the formation of the thorax renders it 

 quite distinct : it is much smaller than H. ruJicornU ; the sides of the 

 thorax are straighter and more ])arallel, less rounded in front, and less 

 contracted behind, and the posterior angles are very blunt and almost 

 rounded ; in nearly all other respects it closely resembles the above 

 species. L. 10 mm. 



This species was first observed as British by Mr. Waterhousc (Ent. Ann. 1863, 08), 

 but he did not know the locality of his specimens ; it has beeu taken on Cannock 

 Chase and, I believe, in the isew Forest, and also iu Ireland. 



(Sub-Gen. iii. Harpalus, i. sp.) 



I. External interstices of elytra entirely punctured, 

 i. Colour very variable, metallic ; legs almost 



always red ; apex of elytra strongly emarginate, 

 especially in male ; length Sj-lOV mm. . . . H. iEXECS, /•'. 

 ii. Colour black, not metallic ; legs bkck, tarsi red; 



apexof elytra slightly sinuate ; length 11-11 mm. H. CALCEATUS, Sturm. 



II. External interstices of elytra smooth (except for 

 the large regular punctures or pores on the mar- 

 gin, and also at apex iu some species) ; apical margin 

 of elytra simply more or less sinuate.
