superantes. Oouli extantes. Rostrum validum, coxas anticas attingens. 

 Antenna) graciles, quinque-articulane, corporis dimidio paullo longiores; 

 articulus 1 us faciem attingens. Thoracis cornua lata, sat longa, apice trun- 

 cata, oblique poirecia. Scutellum attenuatum, corporis dimidio brevius, 

 apice rotundatum. Pedes longiusculi, sat graciles. 



Body nearly elliptical, thickly and rather roughly punctured. Head 

 small, conical in front, a little longer than broad ; lateral lobes conniving 

 much beyond the middle lobe. Eyes prominent. Rostrum stout, extending 

 to the fore coxa?. Antenna? slender, a little more than half the length of 

 the body; first joint extending to the front of the head ; second a little 

 shorter than the third ; fourth much longer than the third ; fifth shorter 

 than the fourth. Thorax with a slight transverse ridge between the horns, 

 which are broad, slightly tapering, truncated at the tips, slightly ascending, 

 extending obliquely forward, about half the length of the intermediate 

 breadth of the thorax; a transverse callus on each side in front. Scutellum 

 a little less than half the length of the abdomen, attenuated towards the 

 lip, which is rounded. Pectus not keeled. Abdomen with no ventral 

 spine. Legs rather long and slender. Membrane of the fore wings with 

 longitudinal veins, some of which are foiked. 



The long horns of the thorax and the much less acute sculellum 

 distinguish this genus from Piezosternum.

Teslacea; venter disco sparse punctata, segmentorum angiitis poslicis 

 nigris ; membrana cinerea.
