generic characters founded on sexual characters only, the great like- 

 ness of a Harpalid to another, as well as the great similitude in 

 colour and sculpture, renders the adoption of these characters 

 necessary. I am not aware that the character derived from the 

 greater dilatation of the tarsi of the male, and the clothing with 

 squamae underneath, fails in the series of the South African species. 

 The TIarpalides are divided in three groups. 



Antennas short, intermediate joints submoniliform ; tarsi 

 not dilate nor squamose in both sexes Dajptidce. 



Antennse filiform; anterior tarsi dilated in the male, and 

 spongy underneath Anisoclactylidcp. . 



Antennse filiform ; anterior tarsi dilated in the male, with 

 two series of diagonal squamulse underneath Harpalidce. 



" 'Group DAPTID^. 



Synopsis of Genera. 



Antennae geniculate; prothorax and elytra cylindrical; 

 anterior tibiae deeply sinuate outwardly and tridenticulate Batoscelis. 



Antennae subgeniculate ; prothorax cordiform ; elytra de- 

 pressed; anterior tibiae not sinuate externally Agriodus. 



Group ANISODACTYLID^. 



Synopsis of Genera. 



Anterior and intermediate tarsi of the male spongy, but 



not thickly, and the basal one glabrous, a little dilated ; 



ligula narrow, setulose at the apex ; paraglossae much 



longer, lobate, diverging apically, no median tooth in the , p 4. fj

Anterior and intermediate tarsi broadly dilate, basal 



joint of the intermediate ones glabrous ; ligula very 



narrow ; paraglossae lobate, much longer than the ligula, 



no tooth in the mentum Anisodactylus. 



Group HAEPALID^. 



Synopsis of Genera. 



I. 



Anterior tarsi of male slightly dilated, intermediate ones 

 narrow, not squamulose. 



Four joints of the anterior tarsi squamulose, intermediate 

 ones glabrous ; ligula broad, as long as the paraglossae, 

 which are equally broad, united with it and with the 

 apical outer angle diagonal ; mentum without any median 

 tooth ; elytra flavescent with green bands ; intervals 

 smooth Bradybcenus. 



Basal joint of the anterior tarsi glabrous, the second, 

 third, and fourth slightly dilated and squamulose, inter- 

 mediate ones narrow, not squamulose, basal joint of the
