150 NOTES ON AUSTRALIAN COLEOPTERA, 



its apical segments finely punctate. Dimensions: 18-19 x 9 mm. 



Hab.— Bourke, N.S.W. (R. Helms). 



Three specimens given me some time ago by the late Mr. R. 

 Helms show a species near //. abdominalis Lea, in sculpture, 

 near H. memuonius Pasc, in form. It belongs to Maeleay's 

 Sect, ii., Subseet. iii., and may be distinguished by the com- 

 bination of large size, parallel form, moderately nitid surface, 

 with unusually fine sculpture. It is quite distinct from //. 

 depressiusculus Mac!., which T have from the same district, and 

 which has distinct costate intervals and larger seriate punctures. 

 It is separated from //. hepaticus Pasc, by structural as well as 

 colour differences. I can find no sexual characters. 



Type in Coll Carter. 



Pteroh ulceus gilesi, n.sp. 



Ovate, rather convex, opaque piceous-black above, nitid black 

 beneath, antennae and tarsi castaneous. 



Head and pronotum apparently quite smooth, epistoma rounded 

 in front, its suture well defined at, sides only, eyes separated by 

 a distance little more than the width of one eve, antennae robust, 

 joint 3 as long as 4-5 combined, 4-7 obconic, 8-10 transverse, 11 

 ovate. Prothorax 4 x 9 mm., length measured in middle, width 

 at base, arcuate-emarginate at apex, strongly bisinuate at base, 

 sides arcuately converging from base to apex (where it is less 

 than half as wide as base), anterior angles well rounded but 

 prominent, posterior acute and slightly dentate, explanate mar- 

 gins moderately wide, and subhorizontal, with extreme border 

 slightly retiexed; disc rather convex, medial line clearly im- 

 pressed, basal fovese shallow. Scutellum smooth and rounded. 

 Elytra of same width as prothorax at base and about thrice as 

 long, ovate and rather convex, explanate margins widest at 

 middle (here about one-fifth of width of an elytron), obsolete at 

 apex, extreme border reflected; finely seriate-punctate, intervals 

 quite fiat and smooth, the 1st (sutural), 3rd, 5th, and 9th wider 

 than the rest; the punctures evanescent towards apex, mere pin- 

 pricks elsewhere, except on lateral row, where some six punc- 

 tures of large size are apparent. (In the £ specimen the
