NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
I have beaten numerous specimens into the umbrella from 
several dwarf Eucalypts growing almost on the sea-beach; for a 
long time, even on hot days, they feign death, rolling up the 
abdomen, tucking in the antennae, and then lying on their sides. 
Selenurus tricolor, n.sp. 
g. Elongate, feebly shining, depressed. Head black, sides im- 
mediately in front of the eyes testaceous; prothorax testaceous, a 
large black blotch — occupying most of the upper surface — irregu- 
larly W-shaped ; scutellum black ; elytra dark bluish-green ; 
abdomen testaceous, the lower surface having the 1st segment 
immaculate, 2nd with a small spot on each side, 3rd with the 
middle of base, 4th with entire base, the 5th (except apex) and 
the entire 6th and 7th black, the markings on the upper surface 
are somewhat different, there being more black towards the sides; 
meso-, and metasternum, except sides, legs and antennae black; base 
of coxae testaceous. Clothed all over — sparsest in the middle of 
meso- and metasternum — with short pale pubescence. Very 
minutely punctate all over, except on the elytra where they are 
dense, rugose, and shallow, but obliterated at apex. 
Head not much longer than wide; eyes rather large and promi- 
nent; antennae slender, reaching posterior coxae; 1st joint as long 
as 2nd-3rd combined, 2nd very short, 4th as long as 1st, 4th-llth 
equal or very slightly diminishing to apex. Prothorax the width of 
head ; irregularly depressed ; strongly rounded in front, sides 
constricted near base, base feebly sinuate. Scutellum small, 
truncate, a shallow depression in its middle. Elytra not one and 
a half times the width of prothorax at base, and about one and a 
half times the length of head and prothorax combined; each 
wedge-shaped ; margins and suture thickened — especially towards 
apex; with traces of costae (visible to the naked eye, but much 
confused with a Coddington lens). Penultimate segment of 
abdomen widely emarginate. Legs long and thin. Length to 
apex of elytra 6, of abdomen 8 \; width If mm.
