the upper side ; shape and sculpture of the head and clypeus similar 

 to that of C . pilosulus ; the prothorax is covered with nearly con- 

 fluent punctures separated hy irregular, not scabrose walls, the 

 punctures do not bear each a short, appressed hair, and are equi- 

 distant and somewhat remote ; the elytra, including the greatest 

 part of the suture, are pluri-costulate and covered with nearly 

 contiguous punctures the irregular walls of which make the 

 surface appear shagreened, and each puncture bears a minute 

 appressed sub-flavescent hair ; the pygidium is briefly pubescent all 

 round, but has on the surface hairs similar to those on the elytra, 

 and those on the under side, especially on the abdomen, are alike ; the 

 claws of all the legs are double and unequal, but the smaller one is 

 nearly as long as the stronger, and all are slightly bifid at the tip. 



Length 8 mm. ; width 4 mm. 



Hah. Transvaal (Potchefstroom). 



Cylichnus vanus, n. spec. 



Male : Head black with the clypeus slightly brown, prothorax and 

 elytra chestnut-brown, but with the median anterior part of the 

 former a little infuscate ; both the head and clypeus are equally 

 shagreened, the clypeus is short but broad, straight a-t the apex and 

 with the outer angles slightly rounded, and is divided from the head 

 by a conspicuous transverse carinule ; prothorax very finely punc- 

 tured, the punctures are very dense, and among them are some large 

 ones bearing each a very short, appressed greyish hair ; prothorax 

 with hardly any puncture ; elytra elongate, only slightly broader 

 than the prothorax at the base but l^roader at the apex, plainly 

 bi-costate on each side, but having also a less well-defined third 

 discoidal costule, the suture is raised, and it is covered by very 

 closely set punctures bearing each a minute greyish fiavescent 

 appressed hair ; pygidium, abdomen, and hairs with similar hairs 

 which are not, however, so closely set ; legs testaceous. 



Female : The female is very different from the male ; it is reddish 

 brown all over, the prothorax has much more numerous cicatricose 

 punctures and the elytra are covered with broad very closely set 

 punctures having a smaller one in the centre, these punctures 

 are more cicatricose in the anterior than in the posterior part, the 

 appressed hairs are considerably less dense and are finer. 



Length 9 mm. ; width 5 mm. 



Hah. Cape Colony (Transkei). 



This insect somewhat resembles in general appearance some species 

 of Congella.
