confluent ; short stiff bristles situated in large punctures dispersed all over the 

 elytra ; the flattened lateral apical portion of the elytrum separated from the convex 

 part by an oblique groove ; apex truncate. Underside and legs grey ; apex of 

 tibiae brown. Anal segment conical, shorter than segments 2 to 4 together, tergite 

 pointed.

113. Exocentrus nitens spec, no v. 



H. Shining black ; head, antenna and legs rufous brown ; bases of third and 

 fourth antennal segments, apices of abdominal segments, and scutellum, white ; 

 elytra with two irregular transverse white bands consisting of scale-like hairs, one 

 close to base, the other at basal third, curving backwards near suture, the hairs 

 composing them not close together anywhere. 



Pronotum densely punctured, suddenly constricted at apex, the sides being 

 dilated ; this dilated part bears posteriorly the side spine, which is long, pointed, 

 and directed obliquely backwards ; in front of the spine there are four stout, 

 spine-like hairs, one behind the other. Elytra with similar stout hairs all over ; 

 seriate-punctate, the punctnration disappearing before apex, seven rows between 

 scutellum and shoulder. 



Length, 3 mm.

114. Exocentrus seriatus spec. nov. 



? . Dark brown ; antenna, tibiae, tarsi and trochanters rufescent. Bases of 

 antennal segments, a thin mesial line on pronotum as well as a large triangular 

 discal spot and a smaller one above lateral sjiine, suture of elytra and numerous 

 short lines, grey ; head, underside and legs also pubescent grey ; some of the linear 

 spots of the elytra confluent before the apex near the suture ; sides of elytra with 

 smaller spots than disc. Elytra regularly punctate-striate from base to beyond 

 middle, the punctnration becoming sparser farther back and disappearing altogether 

 before end ; there are only four stripes of punctures between suture and shoulder, 

 and these stripes remain quite regular to the very base.

11.5. Exocentrus strigosus spec. nov. 

 cJ. Dark brown, tibiae and tarsi rather paler. Stiff hairs longer and thinner 

 than in the other African species known to me. Antennal segments grey at base. 

 Elytra regularly punctate-striate from base to apex, the stnjjes close together, seven 

 betwetn scutellum and shoulder; four grey transverse bands, all ill-defined, tlie first 

 behind shoulder, the second a little farther back, reduced to a spot which stands 

 close to the suture, the third before middle, widened at sides and at suture, including 

 Bome black spots, the fourth at apical third.
