almost certainly belong to Ora^ as here understood. The Nigerian O. 

 macropus is more elongate and has densely rugose, less ex^^lanate elytm. 



11. — Ora macropus^ n. sp. 



Broad-oval, explauate laterally, moderately shining, thickly pubescent ; 

 obscure testaceous, the prothorax. -with several faint spi)ts on the disc, the 

 elytra with vaiious irregular, loiigitudijially coalescont, streaks and angular 

 markings extending from a little below the base to just beyond the middle 

 (a triangular patch near the centre of the suture the most conspicuous), the 

 antennae (joints 1-3 excepted), and the posterior femora in their outer half, 

 black or piceous ; very densely, finely, the elytra more distinctly, punctate, the 

 punctures on the depressed basal portion of the latter coarser and transversely 

 confluent. Head small, foveate on each side between the eyes; antennae long, 

 slender, joints 2 and 3 short, equal, 4-11 elongate, filiform. Prothorax short, 

 rapidly, arcuately narrowed from the base, deeply hullowed in front opposite 

 the eyes, the anterior angles sharp and prominent. Elytra depressed along the 

 suture anteriorly, somewhat acuminate at the apex, with a distinct sutural 

 groove extending to beyond the middle, the margins very prominent. Posterior 

 coxae without plate. Posterior legs very elongate, the tibiae curved, wddened, 

 and 5;liarply carinate, the upper spur nearly as long as the elongated first tarsal 

 joint, the latter much longer than the other joints united. 



Length 5|, breadth 3^^ mm. ( $ .) 



Hah. S. Nigeria {D. A. MacAlister: 1902). 



One specimen, certainly $ , as shown bj^ the depressed scutellar 

 region of the elytra. Very like 0. rugipennis, from Madagascar, but 

 much larger, the elytra more broadly explanate, the two foveae on the 

 head smaller, the puncturing of the prothorax denser and that of 

 the elytra coarser, the posterior legs unusually elongate, the upper 

 tibial spur also very long. Scirtes explanatiis Pic (1913), length 

 3| mm., from Dahomey, must be a somewhat similar insect. S. liiero- 

 glyphicics Guer. and S. scriptus Cast., from Senegal, have maculate elytra, 

 but differ in other respects from 0. macropus. 



12. — Ora vigintiguttata, n. sp. 



Oval, shining, finely pubescent ; testaceous, the eyes and palpi, the 

 antennal joints 4-11, the base of the head, and the elytra black or piceous, 

 the elytra each with ten sharply-defined spots or streaks — three at or near the 

 base, transversely placed, three at about the basal third (the central one 

 curved, the outer one oblique and extending forward laterally so as to nearly 

 join the humeral spot), two at the apical third (the inner one oblique and 

 reaching the suture, the outer one transverse), and two at or near the tip, — and 

 the suture to beyond the middle, pale flavous ; densely, somewhat rngosely, 

 the head and prothorax very minutely, punctate. Head rather small, slightly 

 hollowed on each side anteriorly: antennae moderately long, not very slender,
