Psydestis. 

 Rostrum breviusculum, cylindricum, validum, subarcuatum ; scrobes 

 submedianse, ad oculos currentes. OcuU rotundati, tenuiter gra- 

 nulati, antice modice approximati. Scapus oeulum attingens ; 

 funu'ulus 7-artieiilatus, articulis duobus basalibus longiusculis, 

 caeteris brevibus ; clava distincta. Prothorax transversus, utrinque 

 ampliatus, basi bisinuatus, lobis ociilaribus obsoletis. Mytra 

 cordata, convexa. Coxce anticae baud contigiiae ; femora crassa, 

 dentata ; tihioe breves, compressse, intus bisinuatse, extus rectae ; 

 tarsi articulo ultimo tenuato. Mesosternum depressum, valde 

 transversum. Abdomen segmento secundo brevi. 



Allied to MelanteriiLS ; but differs in its short stout rostrum, 

 absence of ocular lobes, and short second segment oif the abdo- 

 men. There is also an evident affinity between this genus 

 and Diethusa^ Enide, and Lyhmha — genera referred by me to 

 the Erirhininse, from their apparent connexion with Gerynassa^ 

 Erytenna^ &c. ; but I think now that they will be better placed 

 in the neighbourhood of Melanterius.

 momeo plagiatim vel maculatiin varia ; rostro capite sesqiiilongiore,

Poropterus tetricus.
