Head not impressed between eyes ; these prominent and 
suboval. Rostrum short, broad, and slightly concave. Scrobes 
distant. Two basal joints of funicle subequal in length. I'ro- 
fhorax strongly transverse, sides strongly dilated Id bas.e : 
base strongly bisinuate and distinctly wider than elytra. 
SrufclJinu transverse. I'Jhjtra slightly dilated at shoulders, 
thence parallel-sided to near apex : striate-punctate. F cm ova 
feebly dentate. Length, 5.1 mm. 
Jldh. — Queensland: Cairns (Henry Hacker). 
The base of prothorax distinctly wider than the elytra 
will readily distinguish from all previously described species. 
On abrasion the j^i'othorax is seen to be supplied with rather 
small, isolated punctures : those on the elytra are fairly largfe, 
round, and in distinct stride, but before abrasion a])pear to 
be much smaller and narrowly oblong. 
Myllocerus abundans, n.sp. 
Black, appendages in places obscurely diluted with red. 
Densely clothed with scales, usually more or less g^reen in 
colour. In addition with numerous setse, which on the elytra 
have a tendency to form in double rows on each interstice. 
Head narrowly impressed between eyes ; these oblong 
oval- Rostrum short, but rather narrow, slightly constricted 
in middle, feebly concave along middle. Scrobes deep, 
large, and approximating behind. Antennae stout : scape 
grooved below ; first joint of funicle as long as second and 
third, second as long as third and fourth, seventh slightly 
longer than sixth. Frothoru.r transverse, apex much nar- 
rower than base, and slightly incurved to middle : sides 
strongly rounded, base trisinuate, the median sinus small and 
the width of scutellum. ScuftUum transverse. Eh/tra not 
much wider than and closely applied to prothorax ; striate- 
punctate. Femora feebly dentate. Length, 6^ to 8t^ mm. 
]f(ih. — N.W. Australia: Roebourne (C. French). 
Judging by t'he numerous specimens before me, the 
colour of the scales seems subject to alteration after death, 
either through improper treatment or throug^h oily exuda- 
tions. When alive the scales are probably of an uniform 
bright green, but in specimens before me there are patches, 
varying from single scales to large, irregular areas, in which 
the process of change appears to be as follows: — From bright 
green to golden green, then to bright golden, then to dull 
golden, and finally to ashy, in this stage all lustre having dis- 
appeared : the patches are never symmetrical (unless the 
whole of the scales are changed), but may be confined to one 
side, and appear in some instances to have been altered 
through contact with other insects in the bottle in which 
they were collected. I believe in other species of the sub- 
familv the scales are also subject to alteration.
