21. simulatrix, sp. nov. Oblonga; sat nitida; fusca; tarsis 

 obscurioribus ; antennis (basi excepta) nigris; capite pro- 

 thoraceque sparsim subtiliter, elytris minus subtiliter minus 

 sparsim, punctulatis. Long., 2 1.; lat., 11. (vix). 

 Very like M. inconspicua, but larger, and with longer antennae, 

 which, however, are shorter than those of the specimen men- 

 tioned above as possibly the male of that species. The antennae, 

 moreover, are wholly black, excepting the basal three joints, w^hile 

 in J/, inconspicua the joints beyond the third are only near their 

 apex, of a darker shade of fuscous than at their base ; joints 2 

 and 3 are about equal to each other, and (together) both to 

 joint 1 and joint 4. The puncturation of the elytra is e\'i- 

 dently finer and a little closer than in M. inconspicua.

 I unfortunately possess only a single example of this insect, and 

 it has dried in a position in which I cannot see the structure of 

 the anterior coxal cavities as distinctly as I could wish, but I am 

 almost certain that they are closed behind. I have, however, 

 placed this doubt on record by the note of interrogation above. 

 The species bears much general resemblance to a darkly-coloured 

 example of Monolepta modesta, differing, however, in its antennae, 

 which (in one sex at least) are scarcely shorter than the body, 

 having the basal joint evidently longer than any of the following- 

 three, the second less than half the length of the first, the third a 

 little longer than the second and only a little shorter than the 

 fourth ; the basal four joints testaceous, the rest piceous. The 

 head and prothorax are like those of M. modesta, but the latter 

 is proportionally smaller. The epipleurae of the elytra are better 

 developed behind the middle than in the other species of Monolepta 

 described above.

COCCINELLID^. 



The species treated of in this paper belong to the group of 

 Coccinellidce, called by M. Mulsant Trichosomidce. The number 

 of new species I have to add — all, or nearly all, of them occurring 

 in the southern part of this colony — are more than the entire 

 number previously known from the whole of Australia ; from 

 which it will appear that this group of insects presents a very 

 inviting field for the researches of the Australian naturalist.
