424 PROCEEDINGS OF SECTION D. 
of the elytra is something like that of antennarius. Com- 
pared with the description of rufescens, this species appears 
to be larger, prothorax not at all strongly punctured, and 
there appear to be a number of differences in colour. 
DiTRoPiDUS LZVICOLLIS, n.sp. 
Briefly ovate; testaceous; head and prothorax tinged (but 
not very strongly) with piceous, but having a very decided 
coppery gloss, and which is continued on to base of elytra, 
its base (and base and suture of elytra) narrowly black, 
punctures infuscate ; sterna and legs in places (and all the 
tarsi) infuscate. 
Head not densely punctate ; median line feebly impressed. 
Prothorax not very densely punctate, but punctures clearly 
defined, becoming slightly strigose at base near sides; basal 
lobe notched. Elytra seriate-punctate, sides unistriate ; 
interstices almost invisibly wrinkled. Length 2mm. 
Hab.—W.A.: Pimjarrah, Swan River, Darling Ranges, 
Vasse. , 
The prothorax at a glance appears to be coppery, but 
when closely examined it is seen to possess but a coppery 
gloss, being really testaceous, with a slight piceous tinge. 
DITROPIDUS PULICOSUS, n.sp. 
Oblong-ovate ; testaceous red; head black, except in front, 
or at base only, or entirely red; prothorax narrowly stra- 
mineous at sides and apex; elytra stramineous, punctures 
infuscate, base and suture with base of prothorax narrowly 
black. 
Head coarsely punctate; median line deeply impressed. 
Prothorax moderately punctate at sides, not strigose, but 
punctures sometimes slightly elongate; basal lobe obtuse. 
Elytra seriate-punctate, the sides feebly bistriate; inter- 
stices impunctate. Length 3mm. 
Hab.—W.A.: Bridgetown. 
The elytral punctures would be moderately distinct by 
themselves, but, being infuscated, they are rendered very 
distinct. In colour the species appears to approach pallidi- 
pennis, except that the abdomen is not paler than the 
sterna, but the punctures are very different. 
DITROPIDUS INSULARIS, D.sp. 
Briefly ovate ; dull blue, in places with purple reflections, 
sides with coppery reflections; under-surface and pygidium 
black; mouth-parts, antenne, and legs (except part of pos 
terior femora) red.
