D. eremita, sp. nov. (Fem.). Elongata; supra plumbeo-nigra, 
prothorace rufo-testaceo; subtus nigroviridis, prothorace 
coxis (anticis aliqua ex parte exceptis) femoribusque (parte 
apicali excepta) testaceis ; pube brevi subtus sparsim supra 
sat crebre vestita ; antennis sat elongatis, articulis singulis 
pube (basin versus cinerea, apicem versus nigra) vestitis, 3° 
quam 2"§ vix tertia parte longiori, ultimo vix perspicue con- 
stricto; capite crebre subtilius punctulato, ante oculos 
modice elongato (quam D. simplicis, Champ., paullo magis 
lato minus elongato); oculis ut D. simplicis; prothorace 
cordato, antice transversim leviter impresso, crebre fortius 
subaspere punctulato; elytris ut D. simplicis, Champ. 
(crebre subtiliter punctulatis, lineis subelevatis 4 instructis). 
Long., 41.; lat. 14 1. 
Resembles D. simplex, Champ., but differs from it by, inter 
alia, the different colouring of its legs and under surface, the 
considerably greater length of its antenn, the evidently less 
prolongation of its head in front of the antenne, and the much 
closer and stronger puncturation of its.prothorax.

NV. melanura, Linn. This now cosmopolitan species occurs in 
widely separated localities in Australia. The examples before 
me are from 8S. Australia, N.S. Wales, and Victoria. 
OXACIS () 
As I have not seen an example of any American species of 
Ozxacis, there is a doubt as to whether, if compared with an 
American specimen, the Australian insects that I attribute to the 
genus might not require the provision of a new generic name. 
Nevertheless, there is no character mentioned in Mr. Horn’s 
diagnosis of the genus (unless it be “form slender,” which 
scarcely fits the species before me) inconsistent with its 
applying to at least the first two of the species enumerated 
below. The other species do not appear to be separable from 
those two if structural differences so great as Mr. Horn includes 
within the limits of Copidita may be regarded as non-generic ; 
although I have little doubt that the aggregates, which I now 
call sub-sections of Oxacis, will sooner or later be treated as good 
genera. 
0. (demera) australis, Boisd. (?). Modice elongata, minus 
angustata ; breviter pubescens; cyaneo-plumbea, capite in 
medio palpis maxillaribus (apice summo excepto) mandibulis 
(nonnullorum exemplorum apice excepto) antennarum basi 
prothorace (macula magna utrinque posita excepta) coxis
