Genus Campoplex. 
Head transversely oblong, moderately long, front broad and not 
very full ; antennae not quite so long as the body, slender, fili- 
form, finely hairy. Wings with the second subcostal cell (areole) 
usually triangular, or rhomboidal, sometimes pentagonal, and 
sometimes the cell is absent. The abdomen is long and slender, 
considerably longer than the rest of the body, compressed towards 
the end, obliquely truncated vertically. It is more obtuse in the 
males, and its appendages are broad and directed upwards ; basal 
segment long, arched. Ovipositor either not so long as the abdo- 
men is wide or nearly as long as the abdomen. 
“ The feet are of medium length and size. The hooks (cro- 
chets) of the tarsi are broad and pectinated ; their teeth are rather 
shorter than in Ophion, and in a great number of species, in those 
especially of small size, these teeth are not numerous and seem 
only to exist at the base of the hooks.” (Brulle.)
