Adelium helmsi, n.sp. 



Purple-bronze, shining, under surface darker bronze. Legs 

 piceous, antennae and tarsi brown, 



Hfiad (3 X 4 mm.) shining and ahnost smooth, widest between 

 the eyes, witli a high rounded transverse ridge between the eyes, 

 above which is a well marked frontal impression. Antennae stout 

 and clothed with brown hairs, 3rd joint longer than 4th and 5th 

 combined, 11th longer than 10th and rounded. Frotliorax (5 x 

 7 mm.) widest slightly behind middle, almost semicircular on 

 sides, with sharper declivity at base. Sides with wide reflex 

 borders and well marked marginal rim the whole way round. 

 Sides forming obtuse angle at apex and base, wider at base than 

 at apex (5 mm. base, 4 nun. apex). Surface smooth or with 

 variable number of fove^e (one to three) near the middle of each 

 lobe of disc. ScuteUum triangular, with rounded angles. Elytra 

 (14 X 10 mm.) very convex, sides rounded anteriorly, then gently 

 curved outwards to the point of greatest width (a little behind 

 half Avay) whence they abruptly narrow to a blunt point. Finely

 mens the seven interstices form an interrupted raised line.

llah. — Macleay River, N.S.W. (Mr. R. Helms, to whom I am 

 indebted for specimens); also taken by Mr. Lea, at Ash Island, 

 N.S.W. 



Easily distinguished for the combination of size and bright 

 bronze colouring, its almost circular prothorax and its marked 

 convexity from any Adelium with which I am acquainted. It 

 has the size of A. striatum, Pasc, the colour of A. ellijHicum, 

 Blackb., and elytral sculpture somewhat like A. coiwexiuscidum, 

 Macl. 



Adelium reticulatum, n.sp. 



Black, shining. Tarsi and front tibiae lightly clothed with 

 short brown pubescence.
