622 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



and wider than head, the shoulders rounded, sides parallel to near 

 the apex, emarginate at base, about twice as long as head and 

 prothorax combined, an oblique impression behind the shoulders. 

 Legs long, intermediate tibia^ and posterior femora arcuate, tarsi 

 as in iS. Icetus, Blkb. 



The 9 differs from the ^ in having the oblique maculae smaller 

 and paler, the legs not so graceful, in the antennae which ^ and ^ 

 are as in ^^ Icef.us. Length 2^, width | mm. 



Hab. — Armidale (D. McDonald); Sydney (Lea). 



I have a female from Galston which differs in being smaller 

 and narrower (1| x ^mm.), with the antennas darker and with a 

 piceous tinge in the middle of the prothorax. I do not think, 

 however, that it is another species. 



Syzeton immaculatus, n.sp. 



9. Oblong-oval, shining. Piceous-black; base of femora, 

 tarsi, antennae and palpi brownish-testaceous. Sparingly clothed 

 above with soft decumbent ashen pubescence; beneath and on the 

 tibiae the pubescence is shorter and slightly denser. Above 

 densely and minutely punctate, the punctures largest and densest 

 about the base of the elytra, smallest on the head, beneath very 

 minutely punctate. 



Head slightly wider than prothorax at its middle, the eyes very 

 large. Protborax scarcely if at all transverse, strongly rounded 

 anteriorly, the base truncate, sides arcuate; at the base there is a 

 short longitudinal excision, and a feebly marked median trans- 

 verse depression. Elytra wider than prothorax, about one and a 

 half times as long as head and prothorax combined, its base almost 

 straight; humeral angles slightly rounded, behind them the sides 

 are parallel to near the apex, an oblique impression behind each 

 shoulder. Legs long, femora thick; intermediate tibiae bent at 

 base, its tarsi with the 1st joint slightly longer than the rest 

 combined; the posterior tarsi with the 1st joint twice as long as the 

 others combined. Length 2^, width | mm.
