of four) longitudinal costae down each, — and those extremely fine 

 and delicate ones. 



Its habits appear to be the same as those of the Madeiran and 

 Canarian C. Wollastonii, as I am informed by Mr. Bewicke that he 

 captured it "in an ants' nest on the Atlantic side of the promontory 

 of the Cape, about three or four hundred feet above the sea." It 

 would seem to be very scarce, for Mr. Bewicke states that he 

 "searched diligently, but without effect, for more;" — adding, 

 " From the locality in which I took it, miles from even a road, 

 amidst thick imderwood and rocks, I should consider it as certainly 

 a true native of the Cape." 



Genus Mimema, now gen. 



Corpus parvum, lineare : capite subpedunculato, in maribus majore quam 

 in foeminis, oculis magnis prominentibus, subtus juguli lateribus in 

 maribus utrinque valde dilatatis, projecturam subconcavam (superne, 

 ante oculos, conspicuam) formantibus : prothorace sublineari-quadrato : 

 mesothorace superne subobservando, scutello parvo : elytris apice trun- 

 cato-abbreviatis, pygidium haud tegentibus: alls amplis: abdomine e 

 segmentis ventralibus quinque composito, segmento apicali reliquis 

 panlo longiore. Instruments cibaria fere ut in Merops [vide Ins. Mad. 

 149], sed antennarum articulo 3 tio vix longiore et clava paulo magis 

 solida (partibus basali et apicali inter se •paulo minus perfoliatis) ; 

 maxillarum lobo externa magis palpiformi ; ligula apice acutiore, in 

 media parte inter palpos labiales angulata, et utrinque ad angulos 

 anticos paraglossia sat elongatis obtusis, interne ciliatis membranaceis 

 exstantibus instructa; et tarsis multo latioribus, articulis l mo et 2 d <> 

 (Imo solum in posticis mascidis) dilatatis et profimde bilobis. Tarsi 

 postici maris forsan 3-articulati ; certe articulus basalis solus dilatatus 

 est, sed sive articulus singulus minutus inter lobos huj us est reconditua, 

 sive duo, etiam oculo valde armato egomet haud affirmare potui.

The two insects* on which the present genus is founded are so 

 very close, in general aspect and structure, to the Madeiran and 

 Canarian Eur ops, that it was not until I had examined them mi- 

 nutely that I could conceive it possible that they should perhaps be 

 regarded as distinct ; whilst even now I am anything but satisfied 

 that they ought not leather to be treated as aberrant members of 



* Whether the Rhyzophagus eapensis and rufulus of Dejean's Catalogue, 

 registered as natives of the Cape, be these two insects (which is not impossible, 

 from their great external resemblance to Rhyzophagi), I cannot tell ; as, however, 

 they are mere Catalogue-species, it fortunately is not of much importance to 

 ascertain.
