foveolatus, Macl.), the punctures in the sutural row smaller 

 and closer than those in the other series, the punctures more 

 widely separated towards the apex ; intervals quite flat, closely 

 and unusually-strongly punctate ; prosternum carinate, its 

 sides with a few large punctures ; abdomen strongly longitud- 

 inally strigose. Dimensions — 10 x 4*8 mm. 



Hab. — Queensland : Cairns. 



A single specimen, quite distinct from all described Aus- 

 tralian species, in shape somewhat like, but wider than, vario- 

 laris, Pasc, with seriate punctures somewhat as in foveolatus, 

 Macl. The ground colour is red, but metallic-green is domi- 

 nant on the head and pronotum, and subdominant on the 

 elytra. Seen in a strong light the red tints prevail, the larger 

 punctures then appearing dark-green on a red ground. The 

 puncturation is peculiar in that the quite regular row nearest 

 the suture has smaller punctures than in the other series, 

 quite evenly placed, the space between punctures in the first 

 and second rows being as 3 I 2. Type, I. 2212, in the South 

 Australian Museum. 



Amarygmus maculicollis, n. sp. 



Elongate-ovate ; nitid greenish-copper above ; pronotum 

 with about 17 large purple spots, not placed in foveae, the 

 elytral punctures also purple; underside, legs, and antennae 

 red; tarsi flavo-setose. 



Head with epistomal suture deeply impressed, front closely 

 and strongly punctate, eyes widely separated by a distance 

 equal to the combined length of the second and third antennal- 

 joints. Antennas with basal- joints very slender, 7-11 success- 

 ively enlarging, three not as long as 4-5 combined, 11 longer 

 and stouter than 10, ovate-acuminate. Prothorax convex, bi- 

 sinuate at apex and base, the central lobe produced forwards 

 at apex, backward at base, all angles deflexed and obtuse ; 

 sides well rounded, with stronger curve in front than behind; 

 lateral carina not evident from above; disc closely punctate, 

 the purple maculae placed apparently quite regularly as fol- 

 lows: four forming a square in the middle, an elongate one 

 behind these on middle line near base, and about six on each 

 side of these (of these two near basal border). Scutellum tri- 

 angular. Elytra convex, subparallel on basal half, tapering 

 towards apex, as wide as prothorax at base ; seriate-punctate, 

 with eight rows (besides a short scutellary row) of subfoveate 

 punctures rather widely separated (the distance between two 

 punctures in the same row being considerably greater than 

 the distance between adjacent rows), with a few elongate or 

 confluent punctures in the series ; the intervals quite flat and
