42 ADEPHAGA. [Bvadijcelhis. 



blunt, so that they appear rounded ; striae of elytra deeper. L. 4-4^ 

 mm. 



Common and generally distributed in England ; Scotland, not common, Low- 

 lands. 



B. collaris, Payk. Considerably smaller than B. harpalinus, but 

 otherwise very closely resembling that species ; the scutellary stria, 

 however, is more obsolete, and the furrows at the base of the thorax not 

 so deep or wide, and not so thickly punctured ; the elytra are shorter in 

 proportion, the stride rather deeper, and the interstices more convex. 

 L. 3i mm. 



A mountain species found on the high moors of North Wales, Yorkshire, and Lan- 

 cashire ; Langdale Pikes ; Skiddaw. Scotland, generally distributed over the Low- 

 lands and Highlands, but not common. Ireland, near Dublin. 



S. similis, Dej. {Tachycellns, Mor.). The smallest species of the 

 genus, pitchy, or pitchy black, with the thorax sometimes red, and the 

 suture of the elytra usually reddish testaceous ; thorax slightly narrowed 

 behind, posterior angles rounded or very blunt, base with a deep punc- 

 tured fovea on each side ; elytra broadest behind middle, with plain 

 strice, the outer ones obsoletely punctured ; legs pitchy. L. 3 mm. 



Heaths and sandy places, &c. ; common and generally distributed throughout 

 England and Scotland. 



HARPALINA. 



The Harpalina contain one genus, Harpalus, w^hich, for convenience 

 sake, may be divided into three sub-genera as follows : — 



I. Head, thorax, and intei'stices of elytra thickly punctured 



throughout Ophonus, Steph. 



II. Head smooth, thorax punctured (except on centre of 

 disc which is smooth); interstices of elytra punctured 



throughout PSEUDOPHONUS, Mots. 



III. Head smooth ; thorax smooth (except at base and ex- 

 treme sides) ; interstices of elytra smooth (except 



occasionally at sides) Haepalus, i. sp. 



KARPAIiUS, Latreille. 



The sub-genus Ophonus contains about sixty species, which are chiefly 

 spread over the northern hemisphere, although species are found as far south 

 as Guinea; the genus Harpalus proper (under which the sub-genus Pseud- 

 ophonus is generally included) numbers upwards of three hundred and 

 fifty species, which are widely distributed throughout the globe, although 

 the majority are attached to the northern hemisphere. The habits of the 

 insects composing the sections are as a rule the same, except that some 

 of the Ophoni, like Zahrus, seem to be to a certain extent gramini- 

 vorous ; they are chiefly, although not altogether, nocturnal, and during 

 the day hide themselves in burrows which they dig under stones, and at 

 the roots of plants, &c. ; like other usually nocturnal Carabidae, they may
