594 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



thorax with sparse, ol)scurely coloured pubescence, elytra with 

 rather dense and very short yellowish pubescence, beneath the 

 pubescence is longest and somewhat paler. Head (including 1st 

 joint of antennas) and prothorax covered with dense punctures, 

 which under the microscope appear as shallow, minutely punctate, 

 rounded pits, from the middle of each of which a small hair rises; 

 scutellum densely punctate; elytra punctate-striate, interstices 

 densely and shallowly punctate; beneath sharply, the alidominal 

 segments shallowly punctate. 



Head with a narrow, shining carina, commencing at the Imse, 

 and ending in a shallow depression between the eyes; antennse 

 slightly passing intej-mediate coxse, 1st joint bent as long as 2nd- 

 4th combined, 2nd short, more than half the length of 3rd, 3rd 

 not as long as 4th-5th combined, these very short, transverse, the 

 joints after the 5th gradually increasing in length and thickness, 

 11th not one and a half times as long as 10th. Prothorax longer 

 than wide, slightly the widest near ajpex, apex rounded, base 

 bisinuate, posterior angles produced and somewhat acute, median 

 line distinct at base, becoming obliterated towards apex, base 

 depressed and obscurely margined, the sides margined beneath, 

 these with the prosternal margins appear as a right-angled triangle 

 on each side, the right-angle of which almost touches the anterior 

 coxae. Scutellum large, subquadrate, apex rounded. Elytra 

 slightly narrower than prothorax at its widest, and not much 

 more than twice as long, shoulder's rounded. Metasternum with 

 an impressed line almost its entire length. Abdominal segments 

 straight, their apices at the side visible from above, causing the 

 elytra to appear somewhat serrate; apical segment obtusely carinate 

 at its extremity. Length 3|-7|, width 1-14 mm. 



Hah. — Galston (A. M. Lea), Lane Cove (Macleay Museum). 



This is a very variable species as regards size, scarcely two 

 specimens being exactly the same; the colour of the scutellum and 

 elytra is also subject to variation. I obtained numerous specimens 

 at an old burnt log in rather thick scrub; the females were boring 

 into the charcoal, and the males actively running about.
