AGRIONID.E. LESTES. 77 



rather large : abdomen slender, nearly linear, being a little dilated at the 

 apex, which In the males is furnished with semicircular appendages, of the 

 female with simple ones; wings half expanded (as in Smerinthus) during 

 repose. Mask of the larvae with a double projection on the upper edge of 

 the mentum. 



From Agrion the species of this genus are distinguished with 

 facility by the areolets of the wings being more numerous, and by the 

 greater portion of them towards the apex, especially on the margins, 

 being either pentagonal or polygonal, rarely quadrangular, the fourth 

 longitudinal nervure being much angulated in numerous zigzags ; 

 the stigma is oblong, and the males are distinguished by having the 

 apex of the abdomen armed with curved forceps ; yet, regardless of 

 these obvious distinctions, these insects, as well as those of the 

 preceding genus, were long considered as constituting one species 

 only, and are thus considered in the latest works of the celebrated 

 Latreille, although the discrepancies of the two genera were pointed 

 out by Leach in 1810 ! !
