21. Hapalockrus nitens. 



Apalochrus nitens, Gorb. Ann. & Mag. Nat. Hist. (7) v. p. 79 (c? £) 

 (1900). 



$ . Antennas elongate, rather slender, strongly serrate 

 from joint 4 onward ; anterior tibia? slightly hollowed 

 towards the apex within, the apical portion rather broad ; 

 anterior tarsal joints 1 and 2 elongated, 2 thickened and 

 nigro-pectinate at the apex ; intermediate tibise (PL VIII. 

 fig. 16) greatly swollen, curved, convex externally, deeply 

 excavate within, the upper and lower edges of the cavity 

 strongly, subequally, arcuato-lamellate at about the middle, 

 the upper lamella sinuato-plicate and also deeply excavate. 



$ . Antennae a little stouter, feebly serrate, short ; legs 

 usually much darker, the anterior and intermediate pairs 

 (the bases of the tarsi included) often wholly or in great 

 part testaceous in <$ . 



Length (head extended) 5^-6, breadth 2%-2\ mm. ( <? ? .) 



Hab. E. and S.E. Africa : Mwengwa in N.W. Rhodesia 

 (H. C. Dollman : i., ii. 1914) ; Fort Jameson District, alt. 

 4000 ft. in N.E. Rhodesia (S. A. Neave, in Mus. Oxon. : 

 viii. 1908) : Bulawavo [xii. 1903] and Salisbury [i. 1899] 

 (G. A. K. Marshall). 



The long series, £ ? , obtained by Dr. Marshall and the 

 late H. C. Dollman, the males agreeing perfectly in their 

 structure, vary greatly in the colour in the body (golden- 

 green, green, cyaneous or violaceous, some examples having 

 the head and prothorax green and the elytra cyaneous) and 

 legs, many of the Rhodesian females (but not all of them) 

 having these limbs darker than those from the other 

 localities. Gorham briefly described the sexes, but his 

 definition "erosia" of the J 1 -intermediate tibise gives 

 one no idea of the bilamellate structure. Some of the 

 specimens are labelled as having been found on grass-seeds. 

 Compared with H. bilamellatus and other allied forms with 

 somewhat similar c -characters, H. nitens is a relatively 

 narrower, smaller insect. A ? from Kambove, Katanga 

 (S. A. Neave), may also belong here. 



22. Hapalockrus clavicornis, sp. n. 



<$ , Moderately elongate, cyaneous, the head and prothorax 

 bluish-green in one example, the basal joint of the antennas 

 beneath, a space at the middle of the anterior tibiae, and the 

 base of the intermediate femora narrowly, testaceous, the rest 

 of the antennae and legs (the claws excepted) black or metallic,
