 thorax and elytra red ; length \ inch - 

 discoide^is.

 gins of thorax only often red - rubripes.

 side margin of the thorax red . . lathis. 

 Upper side bluish black ; third inter- 

 stice with two or three deep impres- 

 sions ; thorax without a red margin. . 



quadripunctatus. 



2. Legs more or less pitchy. 



Length 35 lines ; thorax with a deep 

 longitudinal depression at the base ; 



sides of thorax rounded neglectus. 



Length 4 to 5 lines ; thorax with the 

 sides not rounded and without a deep 

 depression at base . . ^ . . . . tenebrosus. 

 c. Thorax narrower in front than behind. 



1. Antennce and palpi entirely red. 



Flat ; length under 4 lines ; thorax 

 with the base slightly emarginate. . . . 



servus. 



Convex ; length 4^ lines ; base of 

 thorax straight. . , tardus. 



2. Antennce and palpi more or less pitchy. 



Length under 3I lines anxius. 



Length over lines. 



a. Palpi red, with the base of each 

 joint black, and the 2nd, 3rd, and 

 4th joints of the antennae black. 



. Length 4 1 lines ; fiat; apex of ely- 

 tra slightly ^rodnced -melancholious. 

 Length 5 lines ; convex ; apex of 

 elytra not produced serripes. 



b. Palpi brown, with the apex of each 

 joint reddish ; antennae brown, ex- 

 cept the first joint, which is red. 

 Length 5 to 6 lines caspius. 



All the above species, from neglectus, have 

 the upper surface black, sometimes with a 

 bluish reflection. 



One species is omitted from the above 

 table, viz., H. picipennis, as it is easily dis- 

 tinguished from all the Harpalus of Group 

 II. by its small size (2 to 3 lines). 



The various species of the genus Harpalus 

 are very similar in their habits and location. 

 They generally inhabit dry, sandy situa- 

 tions, under stones, or clods of earth, j^. 

 rujicornis 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 thicklv but finely punctured. 

 Other common species are puncticolliSy 

 rnfibarbiS) latus, tardus, and anxius, the 

 latter, with us, being partial to dry sandy 

 ground in the neighbourhood of the sea- 

 shore. Those which are not so common 

 are rotundicoUis, punctatulus, azureus, igna- 

 vus, consentaneus, rubripes (which has a 

 great resemblance at first sight to proteus, 

 but from which it may be distinguished as 

 above mentioned), neglectus, serripes, cas- 

 pius, and picipennis Sabulicola is not com- 

 mon, obscurus is scarce, cordatus, rwpicola, 

 and 7nelancholic2is are uncommon, while 

 parallelus, tenebrosus, cupreus, discoideus, 

 qnadripunctatus, and servus are decidedly 

 rare, and may be considered " lucky finds."
