Coleoptera from East Africa. 51 



Alphitopola ventralis, sp. n. 



Capite, pronoto elyt risque pube luteo-fulva vestitis ; scutello, corporo 

 subtus cum pedibus albido-pubescentibus ; antennis griseis ; 

 mesosterno paullo protuberanto. 



Long. 18, lat. 5| mm. 



Hab. Samburu, Brit. E. Africa (C. S. Betton). One 

 female example. 



Head,pronotum, and elytracloscly covered with a yellowish- 

 brown pubescence ; scutellum white ; the whole of the under- 

 side of the body and the legs with a whitish pubescence, that 

 on the legs being- less dense and less distinctly white in colour. 

 Prothorax with a very minute tubercle on each side. Elytra 

 visibly punctured at the base and along the sides as far as 

 the middle ; the derm where rubbed bare of pubescence is 

 seen to have a reddish-brown colour. Antenna? in the female 

 a little longer than the body. 



Alphitopola antennalis, sp. n. 



Fulvo-cinereo-pubescens ; utroque elytro plagis f uscis tribus vage 

 notato ; prothorace utrinque breviter tuberculato ; antennis ( <3 ) 

 quam corpore sesqui-longioribus, cinereis, articulis 4°, 5° 0"que 

 utrisque subtus macula elongata, elcvata, fusca notatis. 



Long. 20, lat. 6g mm. 



Hab. Samburu, Brit. E. Africa (G. S. Betton). One male 

 example. 



Clothed with a pubescence which is partly ashy grey, 

 partly tawny in colour. Each elytron with three ill-defined 

 patches of a dark brown colour — the first behind the shoulder, 

 the second behind the middle, the third (which is the smallest) 

 near the apex. Prothorax with a small but distinct tubercle 

 on each side ; the two anterior and two posterior transverse 

 grooves distinct, the second anterior groove bowed backwards 

 in the middle. Elytra strongly but somewhat sparingly 

 punctured. 



Antenna? about half as long again as the body in the male, 

 cinereous grey in colour ; joints fourth, fifth, and sixth each 

 having an elongated dark brown area underneath. This area is 

 slightly raised and almost nude; it runs along almost the 

 whole length of the fifth joint, but is confined to the distal 

 half of the fourth and the proximal half of the sixth joint. 

 Similar areas to these (which are possibly of a sensory 

 nature) are present also on the corresponding joints of the 

 male antenna? in A. bipunctafa, Th., but in the latter are 

 slightly more pubescent, and therefore less easily seen.
