from Hope's example for separate recognition. We have 

 also a series from Ecuador, but I have seen no examples of 

 V. platyrrhinus from Brazil. 



Epiphoroncus, gen. nov, {tctragonus, Hope) = {quadri- 

 frons, Perch. = occipitalis, Eschs). I have found in the Hope 

 Collection, in addition to the type of Hope's description, a 

 specimen of this species labelled in Percheron's handwrit- 

 ing " quadrifrons, P. localite ? " In Percheron's Mono- 

 graph quadrifrons is said to come from the Cape of Good 

 Hope, and Kuwert has placed it, on account of its reputed 

 habitat in the genus Bidymus. No Passalidge are known 

 in S. Africa, although Kuwert includes several others, and 

 this insect seems to be not uncommon in Brazil. It was 

 tentatively referred (as tctragonus, Perch.) by Kuwert to 

 his species Ilorosojjhus ruMi, but is quite different and 

 agrees with no existing genus, and I have been obliged to 

 form one (characterised later) to receive it. 



Zep)taidax vicinus, Perch. This occurs in Penang and 

 Borneo (Sarawak). It is incorrectly put down by Kuwert 

 as synonymous with L. p)lanus, 111., but is more related to 

 L, angustifrons. It is rather larger and has no large 

 punctures upon the metasternum, which is finely and 

 thickly punctured in front. All these species belong to 

 the genus Leptaulacidcs as recently characterised by Zang. 



Uumclosomus africanus. Perch. = (E. Ixvipcctus, Auriv.). 

 Burmeister and all subsequent writers have relegated this 

 to Didymiis parastictus, Imh. It is a much more convex 

 species with a more thickly punctured thorax and by the 

 median tooth of the elypeus is excluded from the gen. 

 Didymus in Kuwert's sense. In the British Museum 

 there are specimens from Sierra Leone, Cameroon and 

 even from Uganda (Msozi), so that its range is very wide. 



Pcntalohus p)alinii. Perch. Inhabits the Gold Coast 

 (Akropong) and Gaboon. 



Basiliamis cantoo-i. Perch. 



Gonatas naviculator, Perch. 



Pharochilus rugiceps, Hope, is probably P. hrevidentahcs, 

 Kuw., and is exceedingly close to P. 2^olitus, Burm., but 

 the side pieces of the mentum are smooth and sooty. It 

 is placed by Kuwert in another section of the genus. 



Pharochilus cancrus, Perch. = P. dilatatus, Dalm. 

 This has been wrongly identified with a species of Tiberius. 

 The type is a very immature specimen of unknown habitat 

 and the error is therefore not surprising. Percheron
