/4 AUSTRALIAN OOLEOPTEEA : NOTES AND NEW SPECIES. 11. 



Pterohelaeus hackeri, n.sp. 



Elongate-oblong, parallel, convex laterally, sub-nitid black above, nitid be- 

 neath, antennae and tarsi red. Head and proiiotum very minutely punctate, the 

 former widest in front of eyes, anterior part nearly flat, epistoma evenly rounded, 

 eyes large and separated by a distance less thaji lateral diameter of one ; antennae 

 with joint 3 shorter than 4-5 combined, 3-7 olseonic, 9-10 round, 11 bluntly oval. 

 Prothorax 4x9 mm. (leng-th measured in middle), anterior angles rounded, pos- 

 terior acutely produced, sides arcuately converging from base to apex, foliate 

 margins widely horizontal, extreme border very fine; disc with smooth medial 

 line feebly channelled at base, two large basal and two faint lateral depressions. 

 Scutellum widely triaugTilax. Elytra 15 x 9 mm., each with 17 rows of round 

 punctures (about as large as in P. walkeri Br.) besides a small scutellary row, 

 the extreme lateral row faint and irregular; also 8 smooth, nitid eostae, the 2nd, 

 4t]i and 6th more prominent than the rest, the sutural interval wide! and nitid ; 

 lateral margin moderately wide (as in P. elongatus Macl.) and continuous to 

 apex. Submentum finely punctate, abdomen longitudinally strigose, the rest of 

 undei-side smooth. Dimensions : 20 x 10 nun. 



Hab. — Tambourine Mt. and National Park, Queensland (H. Hacker). 



Two examples, both, I think, male, show a convex species belonging to 

 Macleay's Sect, ii., Sub-Sect, i., most neai-ly allied to P. opacus Cart., but differing 

 in its more nitid surface, parallel form, the finely punctured head and pronotum, 

 the elytral pimctures regular thi-oughout (not confused at base; smaller, but not 

 oblitei-ated, at apex). Type in Queensland Museum. 



Since my revision of this group in 1910, the following additions have been 

 described : — P. cylindrieiis Cart., P. opacus Cart., P. durlingensis Cart, and P. 

 oblongus Cart., besides the above species, bringing the total number of the section 

 to 15. 



Pterohelaeus persculptus, n.sp. 



Moderately elongate, depressed, nitid black, antennae and tarsi red. 



Head coai'sely rugose-punetaite, widest in front of eyes, epistoma straight in 

 middle, thence obliquely widening to the canthus, eyes rather small, widely 

 separated by space about twice the diameter of one; antennae having 4 apical 

 joints considerably widened, 8-11 nearly round, 9-10 oblate-spheroidal. Prothorax 

 3x8 mm., the horizontal foliation occupying one half the width; widest near 

 ))ase, anterior angles widely roimded, posterior acute, though blunted at tip, 

 extreme border moderately thick and reflexed, sides rather widely rounded without 

 sinuation; disc clearly, not closely, punctate with wide, light basal depressions, 

 medial line only indicated feebly at base. Elytra two and a lialf times as long as 

 prothorax, sub-parallel, foliate margins horizontal and wide at base, nan-owing 

 to apex, with 16 rows of large, closely set punctures, besides a short scutellarj^ 

 row; those in row near suture showing a tendency to confluence, those in extreme 

 lateral row vei-y large and irregular ; some confused punctures in humeral region ; 

 intervals narrow, fonning mere separating lines between the series, the alternate 

 intervals sub-costate (this more obvious towards apex). Submentum i-ugose, 

 presternum finely strigose, abdomen finely and spai-sely punctate. Dimensioris: 

 17 X 8 mm. 



II ab. — Australia. 



A single specimen in the Queensland Museum is labelled "No. 3455 Relton 

 Bequest," without locality label. It is a very distinct species, in fonn somewhat 

 between the elongate species (Sub-Sect, i) and the shorter species (Sub-Sect, iii)
