This species has not the body attenuated anteriorly ; the hind margin of the pronotum 

 does not form a rounded angle, as in A. telskii ; and the last joint of the maxillary palpi 

 is less securiform than usual. — The description is taken from my MSS. notes.]

A genere Aphono, Sss., differt : corpore gracillimo, pronoto elongato, cylindrico, ovipositore parum elongato 

 sicut in genere Parcecantho, deplanato, recto, valvis apicalibus lamellaribus, deplanatis. 



The described specimen from Chiriqui seems to exhibit some slight differences from 

 the type, which is not at present available for examination : on the fig. 3 a (Sauss. loc. 

 cit.) the hind tibiae are represented with more numerous denticules. Nevertheless, I 

 cannot regard the specimen before me as belonging to a different species,
