All the above species, from neglectus, have the upper surface black, some- 

 times with a bluish reflection. 



One species is omitted from the above table, viz., H. picipennis, as it is 

 easily distinguished from all the Harpalus of Group II. by its small size (£ to 

 3 lines). 



The various species of the genus Harpalus are very similar in their habits 

 and location. They generally inhabit dry, sandy situations, under stones, or 

 clods of earth. H. ruficornis and H. proteus are abundant everywhere, the 

 latter well deserving its specific name from its variability of aspect, but always 

 recognisable by its deeply sinuate elytra, which have the outer interstices 

 thickly but finely punctured. Other common species are puncticollis, rufibar- 

 bis, latus, tardus, and anxius, the latter, with us, being partial to dry sandy 

 ground in the neighbourhood of the seashore. Those which are not so com- 

 mon are rotundicollis, punctatulus, azureus, ignavus, consentaneus, rubripes 

 (which has a great resemblance at first sight to proteus, but from which it 

 may be distinguished as above mentioned), neglectus, serripes, caspius, and 

 picipennis. Sahulicola is not common, obscurus is scarce, cordatus, rupicola, 

 and melancholicus are uncommon, while parallelus, tenebrosus, cupreus, dis- 

 coideus, guadripunctatus, and servus are decidedly rare, and may be considered 

 "lucky finds." 



8TENOLOPHUS. 



The species of this genus may be distinguished by their slender legs, 

 by the intermediate tarsi of the males being dilated, and by the small size of 

 most species (under 3 lines.)
