(widest behind middle in ittsularis) all its angles less wide; Elytra^ seriate punc- 

 tures finer, the intervals fijiely punctate (smooth in insularis). 



The elytral surface is uneven through each fovea forming a pit around 

 which the area is slightly tumid, the combined effect being very different from the 

 convex interval of a striate species. Types in Coll. Carter. 



N.B. — In the abdominal sculpture of H. insularis Hope there is a similar 

 sexual difference to that noted above, but to a greater degi'ee — the c? having 

 rather coarse sparse punctures. My remarks on this point in my revision of 

 the genus (Proc. Linn. Soc. N.S. Wales, 1914, p. 63) apply therefore only to 

 the ?. 



Cardiothorax cwerulescens, n. sp. (Text-fig. 7.) 



Shortly ovate, nearly black with blue reflexions, nitid. 



Head: clypeus rounded, usual frontal impression well marked, with a few 

 punctures near its base. 



Prothorax cordate, widest about middle, arcuate at 

 apex, sub-truncate at base, foliate margins naiTow, sides 

 narrowly sinuate behind; anterior angles subrectangular, 

 posterior deflexed and obtuse, without distinct tooth, disc 

 smooth, medial channel defined, a small fovea on each 

 side (sometimes wanting). 



Elytra wider than prothorax at base, ovate; each 

 with nine fine sulci — ninth on sides — intervals equal, very 

 lightly convex. Legs fine, without sexual characters, 

 tibiae straight, underside smooth. Dimetisions : 11-12J 

 X 4-4J mm. 



Hah. — Eungai (north of Kempsey), New South 

 Wales. (Mr. T. G. Sloane). 



Four examples, taken by Mr. Sloane (July, 1920), 

 show a small metallic species near iridipes, metallicus and 

 coerulso-niger. The first and third of these, however, 

 have clearly dentate hind angles to prothorax and the 

 third also has only 6 clearly impressed sulci on each 

 elytron ; metallicus Cart, has a clearly arcuate or sub- 

 angulate base to prothorax, the posterior angles wider and 

 not bent downwards as in the above species. Type in 

 Coll. Carter. 



Adelium murex, n. sp. 



Brilliant violet-bronze, nitid, pilose; antennae, underside, legs and tarsi 

 metallic black, the last clothed beneath with red tomentum, whole body more or 

 less clothed with long upright, dark hair. 



Head coarsely punctate, the punctures neither close nor regular; foveae at 

 corners of clypeal suture strongly setiferous, 3rd antennal joint as long as 4th- 

 5th combined. 



Prothorax sub-t"uncate at base and apex, widest near middle, thence rather 

 abruptly narrowed each way, sinuate near base, all angles obtuse, disc very 

 coarsely punctate-rugose, the punctures more thickly placed than in A. scutellare 

 Pasc. or A. pilosum Pasc, the rugosity consisting of smooth sub-yermiculate 

 ridges, chiefly conspicuous towards base, foliate margins not differentiated from 

 disc save by less coarse sculpture and transverse ridges.
