GASTEROTBOPIS, nov. gen. 



OBLONGUS, subparallelus, sat convexus. Caput trans versum ; fronte 

 angustiore ; temporibus valde obliquis et deflexis ; cantho post- 

 oculari valido ; oculi rnagni, medio siti. Palpi maxillares validi, 

 articulis 1 minuto, 2 elongate, apice clavato, 3 globoso, 4 rnagno, 

 ovato, acurninato, apice appenclice acuto praedito, 2 et 3 extus 

 appendice minuto, setiformi munitis. Antennae crassae, articulis 

 1 magno, deplanato, quadrate, sequentibus valde transversis, 9, 10 

 majoribus, infra deplana-tis, 11 magno, apice rotundato, infra dentato 

 et excavato. Prothorax latitudine sua fere aequilongus, capite 

 paululum angustior, subcordatus, trifoveatus. Elytra magna, 

 humeris obliquis ; lateribus postice sinuatis ; angulis posticis 

 notatis ; margine posteriore sinuata ; sutura postice utrinque 

 tuberculata ; stria suturali fere nulla, sed sutura praesertirn basi, 

 depressa ; sulco dorsali lato, post medium evanescente. Abdomen 

 elytris subaequale, late marginatuni, basi cava transversa, pro- 

 funda trilobata praeditum ; segmentis dorsalibus, 1, 2, 3 subaequalibus, 

 1, 2 valde tricarinatis, 3 unicarinato, apice angulato, 4 ogivali,

 secundo longiore ; unguibus cinis minutis, aequalibus. 



This new genus resembles Tmesipliorus by its carinate abdomen, 

 the last antennal joints, deformed and excavated underneath in the 

 $ , and its general facies, but it is strongly differentiated by the 

 shape of the maxillary palps, the last joint of ^Yhich is simply ovate
