new African OurculionicTse. 5 



of the rostrum. Rostrum bent before the middle, the apical 

 half flattened dorso-ventrally, with a deep constriction just 

 in front of the eyes ; the scrobes beginning at the middle 

 and not passing actually beneath the rostrum at the base, 

 so that the lower edge of the rostrum (when viewed from 

 the side) is visible beneath the lower margin of the scrobe 

 throughout ; the mandibles triangular in cross-section, the 

 outer surface angulate, forming a longitudinal ridge, the 

 cutting-edge shallowly Insinuate. Antenna with the scape 

 not reaching the eye, the two basal joints of the funicle 

 equal, the third only slightly shorter than the second; the 

 club broadly ovate, as long as the two preceding joints, 

 segmented, the margins of the segments almost transverse. 

 Scutellum distinct. Elytra broader than the thorax, with 

 prominent shoulders and ten striae. Legs moderate, the 

 front pair about as long as the hind ; the femora gradually 

 dilated, with a stout tooth, not furrowed beneath, the hind 

 pair not reaching the apex of the elytra; the tibias com- 

 pressed, strongly bent at the base, the lower edge shallowly 

 Insinuate, the upper surface forming a sharp edge, the apex 

 strongly uncinate, the corbels of the hind pair open; the 

 tarsal claws simple, stout and free. Sternum with a deep 

 prosternal furrow, which is not continued on to the meso- 

 sternum, the front coxre being as widely separated as the 

 mid pair and having a rather prominent internal apical angle ; 

 the mesepimeron nearly twice the size of the mesepisternum, 

 the intercoxal process lying much below the level of the 

 mid coxse, and the front margin of the cavity of these 

 coxae bearing a distinct short projection ; the metasternum 

 between the coxaj more than 1^ times as long as the in id 

 coxa.'. Venter with segment 2 longer than either 3 or 1, 

 but shorter than the two together, the portion of segment 1 

 behind the coxa distinctly longer than segment 2, the hind 

 margin of segment 1 straight, the intercoxal process com- 

 paratively narrow and conical. 



Type, Deiradognathus fascial us, sp. n. 

 . This genus falls into Lacordaire's group Ithyporides, and 

 in Faust's key to the African genera known to him (Stett. 

 Ent. Zeit. 1893, p. 232) it runs down next to Haplocorynus } 

 Fst., which differs in having the femora abruptly clavate 

 and the hind pair extending beyond the apex of the elytra, 

 the second joint of the funicle longer than the first, and the 

 portion of the first ventral segment behind the coxa3 shorter 

 than the secoud segment. 



It is also allied to the Eastern Colobodes, Sehh. : but in 

 this genus segment 2 is as long as 3 + 4, the femora have a
