It (lifters from both tliese raoes in having tlie knees, tibi;e, 

 and tarsi, and all the joiiits of antcinue, on the npper sides, 

 excepting the two first, darkened or browned. The; femora 

 and first two joints of antennic are i)ale flavescent. These 

 slight differences of coloration are analoj^ons to what ocenrs 

 between //, tomentosus, Boh., and tetricus. Per., referred to 

 below. 



Hypolithus tomentosus, Boh., race tetricus, Per. 



Three examples of " tetricus'* (one male and two females) 

 from the place of their orif^^in, Salisbnry, S. Rhodesia, agree 

 exactly with the anthor's dc'scri|)tion, except in size, which 

 ranges from 1 !• by of in the male to 1^^ by G mm. in the 

 females. The dimeiision.s given by Peringuey are 12.f by 

 5^ mm. //. tuinentosus, Boh., varies considerably individually 

 in the depth of coloration of the antennae and the tibite and 

 tarsi of the legs. The tibije and tarsi are always a shade 

 darker than the femora, and the inner edges of the former 

 and the whole of the latter of the intermediate and posterior 

 legs are always more or less infnscated. In " tetricus" the 

 same rule applies, but in a more extreme degree ; the knees, 

 tibise, and tarsi of the posterior (sometimes also of the 

 intermediates) being wholly black, those of the other pairs 

 being more or less infnscated with black. 



The (iilierence in puncturation and pubescence is of the 

 slightest, and the shapes are identical. 



There is nothing that I cau conceive that justifies the 

 acceptance of " tetricus " other than a geographical form or 

 race of Bohemau's tomentosus. 



Hypolithus mozambicus, sp. n. 



Length 13 mm.; width 5 mm. 



Black, with very short pale pubescence and obscurely 

 iridescetit. Antcnnre and palpi ferruginous, the terminal 

 joints of the latter tipped with flavous. Legs black, except 

 coxai and tarsi, which are piceous red. 



Head transvers<', shiny, aeicnlate-punctate, frontal foveie 

 on either side deep, transverse line fine. 



Prothurax transverse (4i by 3 mm.), base wider than 

 apex, the former in the middle shallowly, the latter broadly 

 emarginate, frontal angles roundly produced, moderately 

 declivous, sides gently ampliate to midille, thence very little 

 inwardly inclined to posterior ang'es, which are bluntly 

 right, disc a little convex, finely subconfluently punctate, 

 median line short interrupted above by well-difincd arcuate
