The old No. 925, proving on re-examination to be identical with 

 Entium aherrans, has been expunged from the list, and a new species 

 (Pentarthrum ferruginemn) substituted. The generic name Lasio- 

 rhinus has been replaced by a more appropriate one (Pogonorhinus). 

 Nos. gi2, 913, and 923 have had a new name (Bhinanisus) coined for 

 them. Nos. 917 and 918 have been treated in a similar way. A new 

 species (Agastegnus ruficollis) has been made the type of another new 

 genus, and with it are associated Nos. 930, 922, and 933. No. 1305 

 has been deemed the representative of another distinct form (Bcbo- 

 rhoimlns). Pentarthrum asyerirostrc (No. 921) has hQCOvao, Proconus 

 asperirostris. Euodontus inmctithor ax is a new genus and species. 



I have adopted Pentarthrum ayicale as the typical form of the 

 genus. The five following agree with it in having the margins of the 

 elytra explanated apically; their relationship therefore can be easily 

 perceived. The name Pentarthrum should, in my opinion, be re- 

 stricted to the species from No. 904 to No. 906 ; the succeeding four 

 are certainly of abnormal form, and had the author (the late T. V. 

 Wollaston) of the original diagnosis of this genus considered, as I do, 

 the P. sharpianum the exponent of a new genus, I would have placed 

 Nos. 9 10 and 924 along with it, and then made a new generic name 

 for P. crenatum. Had it been expedient to pursue the course indi- 

 cated, I would have located all the species from No. 910 to 936 after 

 Belinophorus nigrans, so that Sericotrogus subcenesceiis should suc- 

 ceed P. crenatum. 



The student having these remarks and the descriptions before him 

 will, I hope, find the nomenclature of a cossonideous collection much 

 simplified.
