This genus is distinguished from all other Porricondylids by the 

 extremely long, narrow wings (plate 4, figures i, 2), the third vein 

 being united to subcosta by a very oblique cross vein and joining 

 the margin well beyond the apex. The female has 12 or 13, and in 

 one case, 16 antennal segments, the fifth with a short stem about 

 one-fourth the length of the basal enlargement. The male has 16 

 antennal segments,- the fifth with a stem ranging from one-third the 

 length of the basal part to more than twice its length. The palpi 

 are quadriarticulate. The ovipositor is short, biarticulate. The 

 male genitalia are moderate, usually with a short, greatly swollen 

 terminal clasp segment (plate 5, figures i, 2, 3). The type of this 

 genus, C. angustipennis Winn., is in an excellent state of 

 preservation at the University of Bonn and is easily recognized by 

 the very narrow wings. But little is known concerning the life 

 history of these forms.
