378 Desci'iiotive Catalogue [1896. 



depressed, and with a series of broad shallow punctures, the posterior 

 angle with two narrow emarginations bearing a seta each above but 

 close to the posterior angle, base a little depressed, the median longi- 

 tudinal groove on the disk well defined, and wider behind than in 

 front, on each side of it, but nearer to the outer margin, a very 

 deep narrow impression reaching the base ; elytra broader than the 

 base of the prothorax by one-fourth, elongate, parallel, convex, and 

 very declivous behind, narrowly striate with the intervals a little 

 convex and smooth ; the three median abdominal segments have a 

 transverse series of punctures, while on the last one the punc- 

 tures are on the apical margin, closely set and setigerous. Length 

 22 mm. ; width 9 mm.

Teibe SCAEITIDES. 



Ligula very concave and broad {ScaritidcE), or flat and truncate 

 at the tip (Clivinidm) ; mentum deeply emarginate and with a median 

 tooth ; head with one supra-orbital seta {ScaritidcE) or two {Clivi- 

 nidce) ; prothorax united to the hind part of the body by a peduncle ; 

 legs short, stout, the anterior tibiae palmate, digitate outwardly, 

 deeply incised internally and with two long spines ; tarsi slender, 

 joints ciliate. 



This tribe can be divided in two well-characterised sections. 



Ligula very broad and concave, thickly edged with hairs ; head 

 with one seta over the posterior part of the eye ; first joint of 

 antennae very long Scaritidcr. 



Ligula flat, narrow, bisetose at tip ; two set£e over the eye ; first 

 joint of antennse either moderately long or short Clivinidce. 



Group SCAEITID^. 



In the insects included in this group, the form of the ligula is 

 entirely dissimilar from that of any other Carabid. It is semi- 

 circular and very concave, thickly fringed with hairs with the 

 outer angles raised, these and the paraglossae which branch off the 

 outer angles bear a fascicle of hairs ; the median tooth of the mentum 

 projects deeply inwards so as to fit the cavity of the ligula, but is 

 more or less plane outwardly, the tip of the maxillae are normally 

 hooked or sometimes obtuse, and the basal joint of the antennae is 

 very long ; the head has one supra-orbital seta, and the prothorax 

 generally one in the hind angle, but there are exceptions ; the 

 elytra are elongato-ovate, more or less linear, seldom ovate, soldered 

 together and thus apterous, or with wings under the elytra ; the 

 legs are eminently adapted to burrowing.
