CARABIDAE. 31 



Anterior tibire densely fimbriate internally, with long hairs. Agaosoma. 

 Anterior tibise sparsely pubescent internally. Stexomokphds. 



The relations of this tribe are usually considered as with Ptero- 

 stichini; but, in consequence of the third joint of the antennae being 

 almost entirely covered with pubescence, I regard it as closely allied 

 with the Harpalini, and cannot help suspecting that the dilated first 

 joint of the anterior tarsi may be a female rather than a male cha- 

 racter, such as is seen in Gynandropus, &c, in the next tribe. In 

 this case there would be no satisfactory reason for considering it 

 as a distinct tribe, but it would be merged into the next. 



Tribe XIII.— HARP AL.IXI. 



The ligula in this tribe is free at the apex, with distinct para- 

 glossae. The antennae have the first and second joints, and some- 

 times one-half of the third, smooth and glabrous. The palpi have 

 the last joint sometimes cylindrical, sometimes acuminate. The 

 anterior tibiae are more or less thickened and spinous towards the 

 apex, sometimes almost palmated; the anterior and middle tarsi 

 have frequently four joints dilated in the male, and clothed beneath 

 with hairs or papillae; in other genera the male tarsi are not at all 

 dilated; the first joint of the same tarsi in the female is sometimes 

 dilated. The epimeraof the mesothorax are very short; the elytra 

 are rounded and sinuate at the apex, sometimes without, but usually 

 with a single dorsal puncture, rarely with three series of punctures. 



Three groups may be formed on sexual characters : — 



Anterior tarsi of the male not dilated. Dapti. 



Anterior and middle tarsi of the male dilated, with a brush of hairs be- 

 neath. Eurytrichi. 



Anterior and middle tarsi of the male dilated, with squamiform papilla 

 beneath. Hakpali. 



Group I. — Dapti. 



The head behind the eyes is larger than in the other two groups; 

 the legs are thicker and better fitted for digging, and the third 

 joint of the antennae has a smaller portion covered with pubescence. 

 Although the genera may individually be readily recognized, I can 

 give no other characters to separate the group.
