Gren. 69. CeratOllOtUS, <i. U Sm>. n. 



(! 111 fie ( 'Inn -in-lt />. Body armed with a double series of peculiar, highly 

 chitini/ed dorsal processes, lateral and sub-dorsal processes wanting. Rostrum 

 wholly absent. Anterior antennae slender, 4-articulate, 1st joint much the largest. 

 Posterior antenna? and oral parts about as in the preceding genus. 1st pair of 

 legs ditt'ering conspicuously in structure from the 3 succeeding ones, both raini bi- 

 articulate and subeqiial in si/e. Inner ramus of the 4 succeeding pairs very small, 

 iiniartinilate. Last pair of legs comparatively simple. Inarticulate, resembling in 

 structure those in the genus L<niiilt<>iitu<l<'*.
