Range. The Oriental Eegion. 



Body rugose ; pronotum usually much produced ; antenusB 

 inserted in front of, and below the level of the eyes ; upper ocelli 

 slightly in front of the eyes ; frontal cariuce only slightly divergent 

 below the eyes, and produced, united below the frontal ocelJus, 

 and suddenly forking at the lower extremity. Antennae slender, 

 Uliform, uniform in thickness throughout. Eyes large, prominent, 

 raised above the vertex. Body above with a slight carina 

 throughout, granulated, and pronotum more or less rugose ; 

 posterior angles with a strong spine, curving outwards and more 

 or less forwards. Tegmina oval, rounded at the extremity ; 

 wings ample, considerably longer than broad, Eemora frequently 

 dentated beneath ; hind tibiae and first joint of hind tarsi strongly 

 lamellated. 



The species of Seelimena differ considerably, and may, when 

 more raatei'ial has accumulated, be subdivided into several genera. 

 They are aquatic in their habits, the lamellated hind legs being 

 doubtless employed as oars.
