of their identity and that as he feels ittle doubt of 

 G. miiltipunctatus being identical with G. impressipennis, Cast., 

 he thinks Darwini is probably in the same case. It seems to me 

 likely enough that my name is founded on the same species as 

 Sir W. Macleay's ; in which event, although the two names were 

 published simultaneously my name must sink, as Sir W. Mac- 

 leay's paper was read before mine ; but my G. Darwini is per- 

 fectly distinct from a Queensland species sent to me by Mr. 

 Slonne as G. impressipen7iis, Cast, (and in my opinion correctly 

 named), from which it differs inter alia by its having no punc- 

 tures on the fourth elytral interstice and none on the front one- 

 third part of the fifth interstice. Unfortunately my G. Darwini 

 is a female, and the Queensland specimen is a male, — but I think 

 it very improbable that the female of the Queensland species has 

 such deep elytral strise or so strongly prominent interstices 

 (which however are flattened, — not keel like, — except close to 

 the base and near the apex) as G. Darwini. 



LAMELLICORNES. 



ANODONTONYX. 



A. (Scitala) lariguida, Er. I have the type before me and find 

 it to be an Anodontonyx. It is identical with the species that I 

 regard as A. nigrolineata, Boisd. This confirms Burmeister's 

 opinion that the two names are founded on the same insect, but 

 Burmeister makes Boisduval's name the synonym, — whereas the 

 reverse is the case (as Blanchard cites it and as it is quoted in 

 Masters' Cat.). 



HETERONYX. 



Erichson seems to have overlooked this name altogether as he 

 makes no reference to it in founding his genus Silopa to which 

 he refers numerous Tasmanian species. Silopa however, as 

 Lacordaire and others have shown, is quite identical with 

 Heteronyx. In my " Revision of the genus Heteronyx " (P.L.S., 

 N.S.W., 1889, &c.) I was obliged to pass H. {Silopa) glahratus, Er., 

 fumatus, Er., and hepaticus, Er., among the species unknown to 

 me. I have now, through the courtesy of Herr Kolbe, the types 

 of these three species before me and can furnish the following 

 notes on them, assigning to them their places in my arrangement 

 of the genus. 



H. glahratus, Er. This species belongs to my Section III., 

 Group I., Sub-group II., having its labrum elevated above the 

 clypeus, its antenna of eight joints and its claws appendiculate. 

 In my tabulation of that Sub-group it stands beside H. raucinasus, 

 Blackb. (P.L.S., N.S.W., 1889, p. 142) along with 

 H. Gonsangidneus, Blackb. (a subsequently described species). It 

 differs from both of them by its much less closely and more
