Mr. J. O. Westwood’s Descriptions of new 
costali, cum multis aliis minoribus per discum ejus curren- 
tibus ; membrane apicali nervis circiter 20 longitudinalibus. 
Sternum et abdomen subtus mutica. 
Pedes crassi, anteriores 4 sat breves, postici 2 (praesertim in $ ) in- 
crassati ; femoribus elongatis, tibiis brevibus, ad basin curvatis 
et versus apicem internum spind validcl armatis. Tarsi 3-arti- 
culati, articulo lmo crasso, subtus spongioso, 2do brevi, 3tio 
brevi ad apicem incrassato, unguibus 2 sat validis, singulo 
membrana instructo (5 b, pes posticus $ ). 
Abdomen maximum, rotundatum, depression, marginibus detectis. 
Obs. — The possession of tarsal pulvilli, and the insertion of the an- 
tennae, distinguish this genus from Aspongopus, Lop., whilst the simple 
sternum and abdomen remove it alike from Rhaphigaster, Edessa, 
Tesseratoma, Oncomeris and Agapophyta, which last three genera, 
moreover, have only four joints in the antennae. In its simple 
sternum and abdomen and five-jointed antennae it resembles the 
true Pentatomidce, but its habit is certainly much nearer to that of 
the genera above mentioned.
