232 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



I have beaten numerous specimens into the umbrella from 

 several dwarf Kncalypts growing almost on the sea-l^each; 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. 



Selbnurus tricolor, n.sp. 



,;3 . 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 coxpe 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 coxa3; 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 ac 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 costie (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.
