eyes above^ the cavities separated by an elongate, parallel- 

 sided, concave lamella, which is curved upwards into a short 

 horn-like prominence behind ; antennae long, stout, joints 

 3-5 strongly serrate, 6-10 pectinate. Prothorax nearly as 

 long as broad, rounded-subquadrate ; deeply transversely 

 foveate, binodose, and angularly raised in the middle in 

 front, and with a tuft of short hairs arising from the central 

 prominence. Elytra parallel, blunt at the tip. Legs hairy; 

 anterior tarsal joints 1 and 2 thickened, 2 extending over 

 the base of 3 above, black at the apex. 



Var. cf . Antenual joints 3-10 strongly, acutely serrate; 

 prothorax shorter, transverse ; elytra green. 

 ? . The basal half of the head, an elongate, scuti- 

 form patch on the disc of the prothorax, and 

 the elytra green ; the prothorax obsoletely 

 bi-impressed in the centre in front.

The specimen, c? , selected as type was captured by 

 Mr. L. M. Lightfoot in 1918, the others, 2 ^ S and 1 ? , 

 were found in November 1885. The variation in the (^ 

 antenual structure is unaccompanied by any difference in 

 the form of the head in the same sex, and the Ceres and 

 O'Okiep examples must therefore be treated as forms of 

 the same species. H. lamelliger is not very closely allied to 

 any of the Hedybii described by Gorham and others, but the 

 following, H. plicatilis, is nearly related to it. 



14. Hedybius plicatilis, sp. n. 



^ . Elongate, somewhat shining, thickly clothed with 

 whitish pubescence intermixed with long, erect, blackish 

 hairs ; bluish-green, the head (except the frontal cavities 

 and base, Avhich are black) and prothorax (except a large 

 triangular patch on the basal half of the disc, the transverse 

 fovea in front, and a streak along the sides extending from 

 the middle forwards, which are black or metallic) tiavous, 

 the antennse (a streak on joints 1 and 2 excepted) and palpi 

 (the tip excepted), and the intermediate tibise and tarsi, 

 testaceous, the posterior tibise and tarsi slightly inf uscate ; 

 the head and prothorax very finely, the elytra densely, 

 rugulosely punctured. Head (PI. XIIL fig. 13) broad, nar- 

 rower than the prothorax, with two extremely large, deep, 

 oval excavations between the eyes above, the excavations 

 separated by a long narrow lamella, which is raised and
