340 CLASS INSECTA. 



Under each crotchet of the end of the tarsi is seen a mem- 

 branaceous appendage, in the form of a tooth. 



Malachius, Fab. Oliv. Cantharis, Lin. 



One of the sexes has, in some species, an appendage in the 

 form of a crotchet, at the end of each case, which the indivi- 

 dual of the other sex seizes with its mandibles, when it flies 

 or runs too fast. The first articulations of the antennas are 

 often dilated and irregular in the males. These insects have 

 agreeable colours. 



Cantharis {:Bnea, Lin. Panz. ibid. X. 2, three lines in 

 length, of a shining green, with the cases red at the edge, 

 and the front of the head yellow. (See the same works, and 

 Schoenh. Sym. Insect. I. I. p. 67) 



Cantharis hipustulata, Panz. ibid. 3, a little smaller, of 

 a shining green, with the end of the cases red. (See as 

 above.) 



Amongst tlie following melyrides, with filiform palpi, and 

 whose corslet and abdomen are without retractile vesicles, we 

 shall place at first those whose antennae are, at least, of the 

 length of the head and corslet, whose body is generally nar- 

 row, elongated, and sometimes linear, and the crotchets of 

 the tarsi usually, as well as those of Malachius, bordered 

 below, by a membranous appendage.
