labial, and the insertion of the antennas is the same as in the 

 preceding- genus. The anterior tarsi are very much dilated 

 in both sexes. The length of the last articulation of the four 

 posterior ones, equals almost that of the four preceding arti- 

 culations united.* 



The second section, Longipalpi, Avhich have also the head 

 entirely uncovered, but whose labrum is entire, and whose 

 maxillary palpi are almost as long as the head, terminating 

 in a club-form, composed by the third articulation, with the 

 fourth concealed or but little distinct, and in the figure of a 

 little point, terminating the club when visible ; the preceding 

 one is very much swelled. These insects live on the banks 

 of waters. 



PffiDERus, Fabri., 



In which the antennae inserted in front of the eyes are either 

 filiform, or grow thick insensibly, and are longer than the 

 head, whose body is long and narrow, with the mandibles den- 

 ticulated at the internal side, and terminating in a simple 

 point. 



Some {Paederes^ Lat.) have the penultimate articulation of 

 the tarsi bifid.-{-

■f- M. Lefevre has brought from Sicily an insect neighbouring on the 

 Poederus, but evidently forming a new genus. The fourth and last articu- 

 lation of the maxillary palpi is here very distinct, and terminates them in 

 the manner of a knob. The last of the antennse is larger than the pre- 

 ceding, and ovoido-cbnical. The head attaches to the corslet by an 

 elongated pedicle, and on a level at its origin with the head. The corslet 

 is narrow and elongated. The two anterior tarsi are very much dilated. 

 Tiie first articulation of the others is very long, and their penultimate
