subtiliter striatis, striis subtiliter punctulatis, interstitiis 



planis vix manifeste (sub lente forti) punctulatis. Long., 



1-1 1 ; lat., I 1. 



The coloring of the antennae in the unique type is not quite 



uniform, the basal two joints being paler, and the third joint 



darker, than the rest. 



Victoria (Glenelg River). 



MORPHNOS. 



M. Besti, SI. I have lately met with this species (recently 

 described by Mr. Sloane) at the mouth of the Glenelg River, in 

 the extreme south-west corner of Victoria. Mr. Sloane appears 

 to have seen it only from the Grampian Mountains (Vict.), It 

 was not rare in deep burrows under large stones and logs quite 

 near the sea, and a good deal of digging was necessary to un- 

 earth it. 



NOTONOMUS. 



iV. molestus, Chaud. This species is plentiful under stones and 

 logs about the mouth of the Glenelg River, Victoria. Mr. Sloane 

 seems to have it only from the Grampian Mountains. 



DYTISCID.E. 



ANTIPORUS. 



A. (Rydroporus) collar is, Hope. Referring to my note on this 

 species to the eflfect that, though (of existing genera) Antiporus 

 seems the best for it to stand in, yet I think a distinct genus 

 should be formed for it, but cannot myself form one for want of 

 a satisfactory specimen for examination ; Dr Regimbart writes 

 me that he confirms my opinion, and I judge from his letter that 

 he will shortly propose a new generic name for the insect, of 

 which he appears to possess a good specimen. 



GYRINID^. 



MACROGYRUS. 



M. (Gyrinus) ohliquatus, Aube. Dr. Regimbart agrees with 

 me that there is not sufficient evidence to justify this species 

 being regarded as Australian 



M. (Dineutes) Gouldi, Hope. Dr. Regimbart answers my 

 query as to the possible identity of this species (which I have not 

 seen) with M. paradoxus, Reg., by telling me that he has 

 M. Gouldi, and that it is certainly distinct from ^jara(ioa;ws, 

 having its elytra genuinely tridentate behind. 



M. fortissimus, Blackb. Dr. Regimbart tells me that judging 

 by my description he has no doubt of this species being identical 

 with that which Guerin described as Gyrinus striolatus. I had 

 formed the opinion that G. atriolatus is not a Macrogyrus, and
