well marked in this insect, especially that of the large three- 

 jointed antennal club and the very close puncturation of the 

 pronotum. I have seen no Trogoderrna but this one having 

 antennae agreeing with Erickson's description. In my tabu- 

 lation of the Australian species of Trogoderrna (Trans. Roy. 

 Soc, S.A., 1903, p. 162) this species would stand beside T. 

 Adelaides, Blackb., from which it differs, inter aim, by the 

 club of its antennae three-jointed (at any rate in one sex), 

 and the puncturation of its pronotum much closer still than 

 in Adehiidd (entirely confluent, in fact). In a former Memoir 

 (Tr.R.S.S.A., 1891, p. 130) I formed a new genus, 

 Adelaidea, for a South Australian Dermestid widely separat- 

 ed from Trogoderrna generically but agreeing so well as a 

 species with the description of T . rujiia that I expressed a 

 doubt as to whether it might not be possible that it was the 

 species on which Erickson's description was founded. The 

 study of these King Island specimens is conclusive against 

 that conjecture.

Onthophagus. 

 0. ocelliger, Har. I have received from Mr. French seve- 

 ral specimens (both sexes) taken in the far north of Western 

 Australia which I refer to this species. They agree well 

 with the description, but two of them depart from it in hav- 

 ing their eyltra more or less spotted with red. They are ex- 

 tremely close to 0. asper, Macl., but differ from it in being 

 a trifle smaller ; with the pronotum somewhat more nitid, not 

 quite so closely punctulate, devoid of the small tubercle that 

 occupies the middle of the front margin in (at least one sex 

 of) aajjer, and having its base distinctly margined in the mid- 

 dle. The sexes do not differ much mter se; the front tibiae 

 of that which I take to be the male are a little longer and 

 more slender, and the pygidium of the same a little more 

 convex than in the other sex. The presence of a distinct fine 

 line margining the middle part of the base of the pronotum 

 places this species (in my tabulation of Onthophagus, Tr. Roy. 

 Soc, S.A., 1903, pp. 267, etc.) in Group V., where it falls 

 beside 0. henleyensis, Blackb., from which, however, its pilo- 

 sity, closer puncturation of pronotum, unequal elytral inter- 

 stices, and very much smaller size, separate it widely.
