Paracamenta calva, n. spec. 



A little smaller than P. verticalis, and more reddish ; the clypeus 

 is of the same shape but there is a broader smooth space in the 

 anterior part, the posterior is punctate but not scabrose and 

 without erect hairs ; the prothorax and the elytra are similar in 

 shape and sculpture, but are fringed laterally with short, some- 

 what remote hairs ; the under side is equally hairy ; the inner 

 joint of the antennal club is a little shorter than the one following ; 

 the third joint of the pedicel is long and somewhat aculeate inwardly 

 in the median part. 



Length 6-7 mm. ; width 3-3^ mm. 



Hab. Transvaal (Zoutpansberg). 



ID^ECAMENTA, n. gen. 



Mentum of G amenta, maxillae with five teeth only, as in Diplo- 

 bothris, three superposed ones in the upper and two in the inner side, 

 last joint of maxillary palpi long and very plainly fusiform ; clypeus 

 shorter than the head and declivous, parallel laterally, deeply incised, 

 at two-thirds of the length, much narrowed thence, but still parallel, 

 as far as the very slightly rounded apical angles, anterior edge 

 broadly emarginate, , strongly recurved somewhat in the manner 

 of a Trochalus, hollowed in the anterior part, the hollowness being 

 bounded by an impressed line, sub-vertical above that line as far as 

 the median keel which is sub-arcuate and reaches from side to side, 

 plainly declivous thence to second arcuate keel separating it from 

 the head which is plane, the genae are strongly developed, but 

 oblique and not rounded or ampliated in front of the eyes, 

 the antennae are 10-jointed in the male, the only sex known, 

 the 10-jointed club is extremely long, and curved, the third joint 

 of the pedicel long and aculeate inwardly near the base ; facies, 

 sculpture, and build of Pseudocamenta, of which it has also the 

 claws, the drawn-in pygidium, and the free or nearly free abdominal 

 segments, but from which it differs by the altogether different shape 

 of the clypeus, which resembles that of a Trochalidous melolonthid. 



Id^camenta jucunda, n. spec. 



Pale testaceous or testaceous-red, antennae flavous : the hollowed 

 and declivous parts of the clypeus is almost impunctate, but the space 

 between the two keels and the head is covered with deep, closely set, 

 but not quite contiguous punctures ; joints of the club equal, as 

 long as the prothorax, the third one of the pedicel with a plain
