as the female of septemtuherculatum, Baiiib. The two are described 

 as having the unusual character of the pronotum being trans- 

 versely bicarinate, and are both reported from Western Australia. 

 If they are identical and if Westwood is right in referring his 

 insect to 7 -tuberculatum, then coronatum must be treated as a 

 synonym. But with the double uncertainty indicated above, it 

 is probably best to regard the two for the present as both valid 

 species, distinguished from each other by the slight differences in 

 tuberculation that are to be deduced from the descriptions. It 

 may be added that Westwood quotes Reiche as considering that 

 7-tuherculatuin is the female of B. hastifer, Bainb., but decides 

 that this is an error and the type of 7 -tuberculatum a male — in 

 which I have no doubt he is right. 



The eight names enumerated by Masters as synonyms in the 

 genus, with two exceptions, agree with Westwood's determina- 

 tions, and are, I have no doubt, correctly so enumerated. The 

 two exceptions consist in the restoration of Guerin's names 

 i^frontale and recticorne) in place of Bainbridge's {serricolle and 

 hasti/er), in which Masters appears to be right. 



Since the publication of Masters' Catalogue descriptions of 

 Australian Bolbocerata have been published under ten new names, 

 — three of them by Sir William Macleay and seven by me; eight 

 of these ten are extremely distinct species, while two of them are 

 closely allied to previously described forms — viz., terrce-regince, 

 Blackb., and simpliciceps, Blackb. Since I described B. terrce-reginoi 

 I have had the opportunity of examining numerous specimens of 

 B. 2:>roboscideum, Schreib., from various parts of Australia, and 

 find it so extremely variable in sexual characters that I am now 

 disposed to look upon tei-rce-regirice as an extreme local form of it, 

 — a possibility that I suggested when I described the Queensland 

 examples. The differences are sexual with the exception of a 

 difference in the striation of the elytra, and with the knowledge 

 that striation is undoubtedly affected by long immersion in spirits 

 I am afraid that the validity of the species cannot be maintained 

 on this character alone. Regarding the relation of B. simjyliciceps, 

 Blackb., to B. planiceps, Macl., I have nothing to add to what I
