 («) ^rfe Blair. (?)) Mr. Blair writes: "The type of P. piceus Kby appears 

 to be lost, but I send a specimen of what passes with us for this species, and 

 with which I consider P. pruinosiis Pasc. and P. pa.scoei Macl. (det. H. J.C.I 

 identical." (c) My own examples have been compared with Lea's type and 

 secondly with an example of dispar (?) from the British Museum. An example 

 of P. dispar c? (f) much smaller than the S (14 X 9 mm.) is identical with P. 

 broadhursti Lea, but I consider this specimen to be doubtfully conspeeific with 

 the female example sent, and Mr. Lea's name should stand till further evidence 

 is adduced, (d) Mr. Blair states "The type of memnoiiitis Pasc. certainly has 

 quite distinct granules (= tristis Germ.) ." An example of meinnonius sent me 

 from the British Museum agrees with my own example that has been compared 

 with P. tenulstriattis Lea. (e) is certain from example sent of geminatm. (f) 

 fide Blair, with some doubt as to ovalis. 



P. semis Pasc. — A specimen sent from the British Museum is identical with 

 examples in my collection from Walgett and Nan-abri, N.S.W. The type was 

 described as from Victoria. 



P. agonus Pasc. — An example sent is quite new to me, and in size and form 

 near peltatus Erichs., but has head and thorax more cleai'ly punctate, the elytril 

 margins narrower, all intervals f|uite flat, and seriate punctures much finer. 



Pterohelaeus intbrruptus, n.sp. 



Elliptic, depressed, subnitid, black, tarsi and apical joints of antennae red- 

 dish. Head very minutely punctate, eyes separated by a space of about the 

 diameter of one eye, antennae with last 4 joints enlarged, 9th-10th round, 11th 

 oblong, elliptic. Prothorax 3 X 7i mm., length measured in middle, base bisinu- 

 ate, apex deeply emarginate, anterior angles sharply produced — though slightly 

 blunted at extreme end; sides continuing the elliptic curve of elytra but slightly 

 sinuate before the anterior angles; posterior angles acute and falcate; disc nearly 

 smooth or merely microscopically punctured ; foliate margins a little concave, rather 

 wide medial basal impression and shallow foveae on each side of this. Scutellum 

 equilatero-triangnlar. Elytra of same width as prothorax at base, widely ovate 

 and depressed, foliate margins wide and sub-horizontal; irregularly linear-punc- 

 tate, with nine more or less raised inteirvals of which the 1st, 3rd, 5th and 9th 

 are more raised than the others, the 1st bifurcating at scutellum, the 9th eosti- 

 form; from halfway to apex these intervals broken up into rows of noduleK; be- 

 tween the intei-vals are double rows of small punctures, those near suture very 

 irregular; outside the 9th and limiting the foliate margins, a row of large punc- 

 tures ; abdomen finely strigose. Dimensions : c?. 14 X 9, 9 15 X 10 mm.
