92 Descriptive Catalogue [1897. 



joint hardly infuscate, eighth joint quadrate, ninth a httle larger, 

 quadrate, tenth larger than the preceding one, quadrate, eleventh 

 ovate, hardly thickened, truncate at base and acuminate at tip. 

 Female : Variety /3. (?) Antennae more slender than in type, piceous 

 at tip, and with the eighth, ninth, and tenth joints slightly transverse. 

 Length 1-50-1 -60 mm. 



Hah. Natal (Frere), Zambezia (Salisbury), and also the West 

 Coast of Africa. 



In the South African examples the colour is darker, and the last 

 joint of the antennae entirely dark, whilst in the West Coast specimens 

 the ultimate joint is dark at the base only, and in the female 

 the antennae are entirely of the same colour ; this is, however, only 

 a local variety. 



The diagnosis of the female var. ^i is made from one example ; it 

 is impossible to decide if it belongs to a distinct species or not. The 

 habitat of that example is Zambesia (Salisbury). 



Eeichenbachia decipiens. 



Closely allied to both B. sidcicornis and B. picticornis, but the 

 only example I have seen being a male, proves to be a very distinct 

 species. The colour is a little lighter, the antennae more slender, 

 the third to sixth joints long, subcylindrical, seventh much shorter 

 than the sixth, but still longer than broad, eighth quadrate, ninth a 

 little longer than eighth, quadrate, tenth larger and very slightly 

 longer than broad, eleventh fusiform, rather elongate and slender ; 

 the carinulae of the abdomen are more definite and less divergent ; 

 the intermediate trochanters have a very small acute tubercule at 

 base ; the metasternum is broadly depressed, and the last ventral 

 segment is broad and impressed. Male. Length 1-70 mm. 



Hab. Zambezia (Salisbury). 



Eeichenbachia subpubescens. 



Oblong, not very thick, ferruginous, covered with a moderately 

 dense and long greyish pubescence, under side of abdomen and 

 antennae infuscate at tip, legs rufous ; head longer than broad, 

 hardly attenuate in the anterior part, trifoveate ; posterior foveae 

 transverse ; antennse slender, joints third to sixth elongate, seventh 

 much shorter, eighth quadi-ate, ninth hardly broader, but longer, 

 tenth larger, briefly ovate, eleventh of moderate size, ovate, 

 acuminate ; prothorax a little broader than the head, rounded 

 laterally, more attenuate in the anterior than in the posterior part, 

 lateral foveae of moderate size, greatly distant from the margin, 

 median one punctiform ; elytra moderately elongate, hardly attenuate
