Practically any species with green scales, belonging to 
the allied genera, would fit the description of M iiUoreriis fim- 
tralis, Boi., so until more information is forthcoming I think 
this name should be regarded as non-existent. 
Myllocerus TREPiDus. Pasc, and duplicatus, Pasc. 
There are four specimens before me, from Port Denison 
and Endeavour River, which evidently belong to one of these 
species, bnt as to which is very doubful if these names really 
appertain to distinct species. The four specimens appear to 
agree very well with either of the formal descriptions, but on 
comparing these together the following apparent discrepancies 
appear : — 
Trepidiis Duplicates. 
Second joint of funiole longer Second joint niiicli longer than 
than first first 
Prothorax short Prothorax very short 
Scntellum oblong Sriitellnm less oblong 
P'lytra Avith irregular white Elytia with white setse in double 
setae series. 
Duplicatus is also said to be more richly coloured, and 
the setose scales otherwise arranged. 
The four insects have the elytral setae arranged in places 
in double and in places in treble series, but the apparent 
arrangement is subject to alteration according to the point 
of view. If, however, the character of the antennae is reliable, 
the specimens will belong to trcpidui^, as the second joint of 
the funicle is but very little longer than the first. 
Myllocerus Darwini, Blackb. 
I have two specimens from Cairns, one of which agrees 
exactly with the description of this sjDecies, but in the other 
three very faint infuscate lines can be traced on the pro- 
thorax. 
Myllocerus speciosus, Blackb. 
A species which appears to be common in North Queens- 
land"* agrees with the description of this insect. The dark 
vittse of the prothorax are somewhat variable in shape and 
width, and the scales on the elytra of some specimens have a 
distinct golden gloss. 
Myllocerus laticollts, n.sp. 
Dark reddish brown : appendages somewhat paler. 
Densely clothed with whitish-grey scales, on the upper sur- 
face obscurely mottled with brown ; in addition with stout 
setose scales or setae ; dense on legs, dense and rather fine on 
antennae, and subseriate in arrangement on elytra, on the 
latter they are but little elevated above the general level.
