CARABIDAE. 11 



gt'iiera. Posterior coxa; contiguous. Lcfrs stout, nior(! or less 

 Jussoriai, the anterior i'eniora especially stout. Middle and poste- 

 rior tibias ciliate or spinulose externally but often very iinely, 

 anterior tibiae palmate, the outer apicaT angle prolongetl, inner 

 side deeply euiarginate with the inner spur above the eiuargina- 

 tion. Tarsi slender. 



From the above characters it is evident that the tribe must be 



sub-divided into two groups in the following manner: — 



lia.sal joint of anteiiiiaj long. Mcntuni broad, concealing at the sides the 



base of the maxillje. Head with one supra-orbital setigerous puncture, 



thorax with one setigerous puncture at the hind angle. Scarites. 



Ba.sal joint of antennae not elongated. Base of maxilhe not covered by the 



nientuni. Head with two su])ra-orlMtaI setigerous i)unctures, sides of 



thorax with two. CijvinjE. 



In addition to the above characters the form of the labial palpi 

 and the paraglossia give additional meansof separating the grouj)s. 



The se.xual characters of the genera of this tribe are very 

 feeble. In Scarites the last ventral segment has four marginal 

 punctures, in the female the inner two are more distant from 

 each other tlian from the outer, while in the male tliey are equi- 

 distant. In PanimachuH some species liave the posterior tibite 

 pubescent within at tip in the male. There are no marginal 

 ])unctures on the last ventral segment, in the nmles there will 

 usually be observed on each side one ante-apical puncture and 

 in the females two, but these are not constant in any respect. 



In the Clivinae the last segment is the same as in Scarites, the 

 tarsi are often alike slender in#both sexes, but when dilated are 

 more so in the male. In Dyscliirius the palpi differ as will be 

 seen below. 



The antennsB vary in the number of glabrous basal joints, the 

 Scarites have four and the Clivina? two. In Jsjndo(jIo.s:<a the 

 i)ase of the third is glabrous, but even here, as in all the Clivime, 

 the second joint though not pubescent is hairy. 



Group Scarites. 



In our fauna two genera occur separated in the following 

 manner: — 



Hind angles of thorax distinct. Elytra with humeral (;arina of variable 



length. Maxillae very obtuse at tip. Pasimachus. 



Hind angles of thorax wanting. P^lytra wilhotit huiucral carina. Ma.xill.i' 



slightly hooked at tip. Scarites.
