608 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



of elytra is partly denuded of pubescence except at the suture, 

 where it is densest, and with a faint golden tinge (in one specimen 

 there is a round spot on each side not touching the suture, and 

 also two transverse rows of four brownish spots (caused by the 

 partial absence of pubescence), one in the middle, the other near 

 the base). Prothorax very densely and extremely minutely 

 punctate; elytra densely and not very minutely punctate, the 

 punctures only visible on both when the pubescence has been 

 scraped away. 



Head (except eyes) concealed l)y prothoracic horn, longer than 

 wide, antennse reaching basal third of elytra. Prothorax (exclud- 

 ing horn) transverse; the horn is large and half as long as entire 

 prothorax; the outer row of tubercles varies in number from 

 eleven to fifteen, lower surface impubescent, highly polished and 

 very minutely punctate. Elytra somewhat flattened above, about 

 one and a half times as long and wide as the prothorax, truncate 

 at base, the sides gradually widening to beyond the middle. Legs 

 slender, tibise straight; posterior tarsi longest, 1st joint slightly 

 longer than 2nd-3rd combined, and about one and a half times as 

 long as 4th; the intermediate with 1st joint as long as 2nd-3rd 

 combined, 2nd-4th decreasing in length, 5th twice as long as 4th; 

 anterior shortest, joints 1st and 4th as long as 2nd-3rd combined, 

 5th as long as 2nd-4th combined. Length 3-^-3|, width 1^-1 1 mm. 



Hah. — Tamworth; in debris from a flood in the Peel River. 



Mecynotarsus amabilis, n.sp. 



(J. Elongate-ovate, subconvex, derm shining. Derm above and 

 below reddish-testaceous, meso- and metasternum darker, protho- 

 racic horn and muzzle red, legs and antennje pale reddish- 

 testaceous, eyes black. Above and below the derm is completely 

 concealed by whitish glistening scales, which are distinct on 

 prothorax and extremely minute on elytra; the elytra have 

 scattered brownish setae with chestnut markings as follows — an 

 indistinct irregular fascia at base, in the middle of each elytron 

 an irregular macula, broad near the suture, narrowing and then 

 bluntly bifurcate, a small irregular spot near apex, apex itself and
