Subfamily CERAPTERINiE. 



This subfamily contains five genera : Homopterus, which con- 

 tains two species from South America ; Cerapterus, which is 

 represented by thirteen African and two Asiatic species ; Artho- 

 pterus, which comprises four African species, but is distinctively 

 an Australian genus, no fewer than fifty species having been 

 described from that region ; Pleuropterus, containing eight African 

 and three Asiatic species, two of which occur in Ceylon and India;

and Pentaplatarthras, all of which are African. The species are 

 characterized by having the labial and maxillary palpi long and 

 free and never concealing the buccal cavity beneath them, which 

 is always open (fig. 202) ; the antennae are made up of from six 

 to ten joints, which are always more or less strongly enlarged and 

 compressed, but very variable. 



Table of Genera. 



I. Antennae composed of ten joints, 

 all free ; labial palpi very robust, 

 with the last joint very much en- 

 larged, strongly truncate and ex- 

 cavate at the apex 



II. Antennae composed of ten joints, 

 joints 2-10 soldered together ; la- 

 bial palpi comparatively slender, 

 with the last joint not markedly 

 enlarged or truncate at the apex.
