gasUraires and the Acanthosomaires, distinguished by their having the tarsi 
composed respectively of 3 and 2 joints; and the latter are again divided 
into Acanthosomates with the mesosternal plate reaching or passing the ante- 
rior margin of the prosternum, and Sastragalates with this plate shorter. 
The first includes only Acanthosoma hcemorrhoidalis (Linn.) ; the Sastraga- 
lates constitute 3 genera, 2 of which are new, Elasmostethus and Cyphostethus 
(Fieh.) being discarded as not divided on natural principles. Figures are 
given oi Acanthosoma hcemorrhoidalis (pi. 2. figs. 16-17) and Sastragala fer- 
rugator (figs. 18-19). Tropicoris rujipes is referred to the Asopiem,
