56 NORTHERN ZOOLOGY. 



XXVI. * Genus TACHYTA. 



Palpi with the last joint most minute, and with difficulty discoverable.- 1 

 Antenna subfiliform, submoniliform, with all the joints nearly equal in length. 



Body oblong, subdepressed. Prothorax narrower than the elytra, rather obcordate. Elytra 

 obsoletely furrowed. 



This appears entitled to rank as a genus in a modern system, not only from having the last joint 

 of the palpi much shorter and more minute than the other Peryphidans, but likewise from its 

 moniliform antennas. It seems to approach to Tachys, but the prothorax is of a different shape 

 coming near that of Bradytus and Curtonotus. It seems to be the analogue of Dromiustrunca- 

 tellus and affinities. 



(82) I. * Tachyta picipes. Pitch-foot Tachyta. 



T. (picipes) niyra, nitida ; prothorace obcordato utrinquc unifoveato ; eli/tris lavibus, apud suturam substriatis: striis Icevibus ; 



pedibus piceis. 

 Pitch-foot Tachyta, black, glossy ; prothorax obcordate ; basilar impressions single ; elytra smooth, obsoletely furrowed at 



the suture, furrows impunctured ; legs piceous.
