in the male the hind femora and tibiae are similar, but the fifth joint 

 is tri-dentate underneath. 



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



Hab. Cape Colony (Cape Town, Stellenbosch, Clan\Yilliam). 



The habitat of this species does not seem to extend much beyond 

 the Cape District, but I have received it also from Clanwilliam. 



Pachycnema pulvebulenta, Burm.,

This species is very closely allied to the preceding one, being very 

 similar in shape and structure, but the elytra are reddish brown in 

 both sexes, and the hind legs of the male are, as a rule, black, but I have 

 occasionally seen some small males with red legs ; there ai'e no scales 

 on the prothorax, along the outer margin, or on the disk which has a 

 much deeper median furrow than in P. obscurepurjnirea ; the scu- 

 tellum is slightly shorter, the sulcate parts of the elytra are almost 

 identical, but the scales which are also white in the male and yellow 

 in the female ai'e not so closely set, and do not form a band, except 

 at the rounded apical part ; under side and legs as in P. obscure- 

 purpurca. 



Length 8^-9 mm. ; width 5|— 6 mm. 



Hab. Cape Colony (Malmesbury, Cape, Stellenbosch, Worcester, 

 Paarl).

Head and prothorax black ; the latter has a margin of yellow scales 

 all round, and on the disk four round scaly spots ; scutellum covered 

 with yellow scales ; elytra brownish red, opaque, and having a small 

 patch of yellow scales under the humeral callus, near the outer 

 margin ; propygidium, abdomen, and pygidium clothed with yellow 

 scales, whitish on the abdomen ; legs black ; clypeus sharply 

 acuminate and with the two apical teeth reflexed ; head and prothorax 

 rugose, clothed with somewhat long and dense flavescent hairs and 

 somewhat distinctly grooved longitudinally in the middle, the latter 

 very obliquely attenuated laterally in the anterior part, and nearly 

 parallel from there ; scutellum very long and sharp, and clothed, 

 except at the base, with dense yellow scales ; elytra a little ampliated 

 laterally past the humeral part, and attenuated from there towards 

 the apex ; humeral callus strongly developed, scarcely sulcate 

 except near the base, but not prolonged into a rounded costa,
