496 A REVISION OF THE STAPHYLINID^ OP AUSTRALIA, 



Head modei'ately strongly and sparingly punctured, with a few- 

 larger punctures behind and near the inner margin of the eyes, a 

 conspicuous depression in the middle just behind the antennae. 

 Antennae somewhat thickened towards the extremity, the first 

 four joints shining, the first two reddish testaceous, 4th joint 

 nearly quadrate, joints 5-9 transverse, 10th and 11th yellowish 

 white, the former transverse, the latter elongate and pyriform. 

 Prothorax strongly convex, moderately strongly and not very 

 closely punctured, with six rather deeply impressed punctures on the 

 disc, three on each side of the middle ; anterior angles conspicuous, 

 reflexed ; the sides strongly sinuate ; posterior angles obtuse. 

 Scutellum rather strongly and very closely punctured in the middle, 

 the sides almost impunctate. Elytra considerably longer than the 

 prothorax, widening posteriorly, rather closely and strongly rugose- 

 punctate. Abdomen narrowed behind, strongly and not very 

 closely asperate- punctate on each side of the middle which is 

 smooth. Legs reddish testaceous. Length 19-22 mm, 



(J Differs from the female in having the head much larger and 

 nearly quadrate, the anterior tarsi more strongly dilated, and the 

 7 th abdominal segment acutely emarginate. 



Johnstone River, Cairns, North Queensland. 



This beautiful species is allied to Actinus imperialis described 

 from New Guinea by M. Fauvel. In colour it agrees precisely with 

 a specimen of that species from Port Moresby in the Macleay 

 Museum, but it is readily distinguished by its much less strongly 

 and closely punctured head and prothorax, less strongly rugose- 

 punctate elytra, and by having the last two, instead of only the 

 terminal, joints of the antennae yellowish white. 



A specimen of this species obtained during October at the 

 Johnstone River was sent to me nearly a year ago by Mr. Henry 

 Tryon, of the Queensland Museum, and recently Mr. Macleay, to 

 whom the species is dedicated, has received a large series from 

 Cairns.
