the pronotum ; a deep transverse incision close to the eyes ; between 

 the eyes horizontal, narrow, with a quadrangular depression; in 

 front produced in the middle over the base of the face, between the 

 antennae, in a quadrangular, shortly- furcate process; Face long, 

 subquadrangular, deflected in a curve ; central lobe long, narrow, pro- 

 minent ; side lobes almost obsolete ; cheek plates very long and wide, 

 lapping over the sides of the central lobe. Antennae inserted on the 

 top of the head, close to the anterior orbit of the eyes (on very short 

 processes), long, setaceous, 4-jointed ; 1st joint stoutest, slightly 

 thickened to the apex, not quite so long as the head ; 2nd filiform, 

 nearly twice as long as the 1st ; 3rd and 4th very slender, 3rd longer 

 than the 2nd, 4th not so long as the 2nd. Eyes large, prominent, 

 viewed from the side subreniforai, the facets small, distinct. Ocelli 

 large, prominent, approximate, inserted close to the eyes behind the 

 transverse incision. Rostrum reaching to the middle of the pro- 

 sternum, very thick, curved; 1st joint ^ the length of the 2nd; 3rd 

 very short and acute ; labruin long, triangular. 



Thorax, Pronotum trapezoidal, constricted before the middle; 

 anterior portion narrower than the posterior, gibbous, on the surface 

 a slight, longitudinal depression ; posterior portion flatter, with 

 3 longitudinal, shallow furrows extending to the posterior margin, 

 the middle one wide ; posterior margin convex, hinder angles rounded. 

 Scutelluni large, triangular ; disk at the base with a large depressed 

 triangle, parallel with the margins ; apex with a long spine projecting 

 upwards. Elytra as long as the abdomen, flat ; at the base on the 

 anterior margin a flat, acute, appressed spine ; Clavus narrow, de- 

 flected ^ to the corium; Co-mini internally diaphanous, somewhat 

 depressed next the clavus ; anterior margin sinuate, overlying the 

 abdomen at its base, but afterwards lying within the connexivum ; 

 Membrane very broad ; close to the inner margin a slender nerve ; on 

 the disk 2 long cells, of which the outer one is largest, its outer 

 marginal nerve and its continuation beyond the cells, strong. Wings 

 broad, diaphanous. Sternum ; Prosternuni with a deep longitudinal 

 rhomboidal furrow, making a long triangular prolongation between 

 the coxae ; Mesosternum with a short xyphus ; Metasternwn convex, 

 with a central keel. Legs strong, 3rd pair longest ; coxa thick ; 

 tliigns thick, 1st and 2nd pairs thickest, subfusiform ; 3rd pair long, 

 cylindrical, slightly bent ; tibia stout, bent at the base, 1st and 2nd 

 pairs widened to the apex, and on the underside expanded into a 

 long, deep channel, incrassated at the sides, the posterior ends pro-
