acnminate, being obliquely truncate at suture ; basal mesial crest blackish, con- 

 sisting of a small and three large tubercles ; the carina between it and shoulder 

 also blackish at base. 



Length, II mm. 



Hah. Benito, French Congo. 



One ?. 



Paroeax gen. no v. 



(??. Similar to Oeax. Eye divided, lower lobe half the width of the cheek. 

 Scape about three times as long as broad, grossly punctured above, with a 

 short cicatri.x ; third antenual segment twice as long as fourth. 3 with horn at 

 anterior edge of frons, and prolonged foreleg. 



Type : nasicornis (1871) Pasc. 



We have a series of Paroeax nasicornis from Cameroons and Benito. 



Phloeus gen. nov. 



? . In a]ipearance similar to Oe.ax. Short. Eye small, divided, upper lobes 

 very widely separate (as in Latisternum), the distance from one to the other equalling 

 nearly the length of the scape. Frons broader than long. Antenual tubercles short, 

 widely distant. Antenna a little longer than the body ; scape rough with punctures 

 above, a little longer than the fourth segment, this longer than third ; fringe 

 vestigial, consisting of short stiff hairs. Prothorax with two dorsal tubercles ; 

 side-spine very small. Prosteruum arched, almost truncate behind ; mesosternum 

 nearly vertical, with roimded, compressed tubercle. Incision of midtibia small. 



Type : Phloeus brevis spec. nov. 



Differs from all the allies of Anci/lonotus and Lasiojjc^us in the tuberculated 

 mesosternum. 



53. Phloeus brevis spec. nov. 



? . Black, densely clothed with a greenish grey pubescence ; upper part of 

 frons, middle of occiput and pronotnm, a large rounded-triangular basal area on 

 elytra (common to both), interrupted at outerside of basal carina, and on each 

 elytrum another large area, beginning laterally before middle and extending to apex, 

 but not reaching suture, irregular behind, oblique in front, dark clay-colour, these 

 areas more or less edged with black. Apex of proximal segments of antennae, and 

 more than the apical half of the distal ones, a patch at each side of base ot 

 pronotnm, and a spot or irregular ring before ape.x of tibiae black. 



Occiput impressed in front, luinctured laterally, with a slight tubercle at each 

 side of middle line. Pronotnm broader than long, side-spine vestigial ; no subapical 

 transverse groove above ; two large compressed tubercles close to apex ; mesial line 

 between them slightly impressed ; disc with large punctures at the sides and 

 behind the tubercles. Elytra truncate at base, coarsely punctured all over : 

 shoulder prominent, somewhat granulated ; a high crest in middle of base ; a 

 trace of a mesial carina behind middle ; declivous part of elytrum somewhat 

 impressed ; suture dotted with brown in and behind middle. Femora and tibiae 

 subcarinate, with single large punctures. 



Length, L! mm. ; elytra, 8^ mm. ; breadth, C mm.
