1902.] Catalogue of the Goleopteva of South Africa. 



685 



posterior callus distinct, the surface is covered with very short black 

 bristles somewhat seriate and longer and stiffer along the suture and 

 the outer margins ; the two apical outer teeth of the anterior tibiae are 

 not connate, and the three are nearly equi-distant ; in the male the 

 hind tibiae are only moderately thickened in comparison with the 

 previously described species, not being thicker than the thighs, they 

 are somewhat strangulate at apex, and simple ; basal joints of tarsi 

 triangular, fifth joint as long as the four preceding, and slightly tri- 

 dentate beneath ; claw a little shorter than the fifth joint. 



Female very much like the male. 



Length 9-10^ mm. ; width 6-6^ mm. 



Hab. Cape Colony (Graham's Town, Port Elizabeth). 



Pachycnema moerens, n. spec. 



This species greatly resembles P. marginclla, but differs in the 

 ■colour which is opaque black in the male with the propygidium, 

 pygidium and abdomen clothed with white scales, and reddish brown 

 on the elytra in the female with the pygidium and abdomen yellow ; 

 there is a faint trace of a scaly band in the anterior part of the sides 

 of the prothorax, but no scaly patches or spots on the disk, and in the 

 elytra the bristles of the sutural and marginal rows are much longer ; 

 in the female the elytra are more distinctly tri-sulcate longitudinally 

 on each side ; hind legs similar in both sexes. 



Length 9 mm. ; width 6 mm. 



Hah. Cape Colony (Caledon, Eiversdale). 



Pachycnema tibialis, Oliv., 

 Entom., i., 5, p. 83, pi. x., fig. 118. 



Shape and sculpture of P. marginclla and P. moerens from which 

 it differs in the colour of the elytra, which are lighter brick- 

 red, and occasionally narrowly infuscate along the outer margin, and 

 in the scales on the propygidium and pygidium being whiter in the 

 male, there is no trace of scales on the discoidal part of the prothorax, 

 and they are even as often as not obliterated along the outer margins 

 in both sexes, but the distinctive character consists in the very long 

 and dense villosity covering the prothorax, and the longer but less 

 dense black or flavescent bristly hairs clothing the elytra ; in most 

 females there are on the elytra some very fine, appressed yellowish 

 but closely set scales. 



Length 8-9 mm. ; width 5-6 mm. 



Hab. Cape Colony (George, Port Elizabeth).
