their only marking, is of the same shape as the corresponding 
patch in Stigmodera amabilis, L. and G. (as figured Tr. Ent. Soc., 
1866, t. 3, fig. 1), except that its external front angle is rounded 
off. The elytra have the same peculiar shape as those of I. Grayi 
in the front of their external margin, being obliquely sloped so 
as to continue the line of the external margin of the prothorax. 
The apical spines of the elytra are as in I. Grayt. 
Semnopharus apicalis, v.d. Poll., appears to be a Metaxymorpha 
and to resemble the present insect ; but it is evidently quite dif- 
ferent, as the apical spot on its elytra is described as of different 
shape, its abdomen is said to be of fulvous color, and its elytral 
interstices impunctulate. 
N. Queensland. 
MALACODERMIDE. 
XANTHEROS, Laarm. 
I cannot see anything in M. Fairmaire’s diagnosis of this 
genus inconsistent with its identity with either Metriorhynchus 
or Trichalus with which its author does not even compare it. I 
have an insect from Queensland which, as a species, agrees so 
well with the description of X. nwhicollis, Fairm., that I can 
hardly doubt its being identical, and it certainly appears to be a 
Trichalus. Metriorhynchus and Trichalus cannot, in my opinion, 
be satisfactorily treated as generically distinct. 
ATTALUS. 
T do not think that the two Australian species which have 
been attributed to this genus (abdominalis, Er., and australis, 
Fairm.), are satisfactorily placed there. Attalus is distinguished 
(among the Malachizdes with 11-jointed antennz) by its possess- 
ing elongate lamellee on its claws and having the second joint of 
its anterior tarsi in the male prolonged over the next two joints. 
In my collection are two Malachiides (from Tasmania and N.S. W., 
the localities from which the two species were described) which 
agree so well with the descriptions of A. abdominalis and aus- 
tralis that I can hardly doubt their being those species; but 
they do not present the special characters just mentioned, and, 
moreover, present a character that in itself seems to require their 
separation from Atta/us—viz., the diminutiveness of the basal 
joint of the tarsi. I cannot ascertain that any genus has been 
named to which these species can be referred and therefore pro- 
pose a new name for them, treating, however, a new species as 
the type of the genus to provide against the possibility of my 
not having correctly identitied abdominalis and australis. 
HYPATTALUS (gen. nov., Malachidarum).
