sutiira fore obsoleta ; ehtris in medio planutia, leviter seriatim 

 jmnctatis, interstitiis alternis elevatis. 



Hah. '' Interior." 



llatlicr narrowly oval, black, shining;;, somewliat (le])ressed ; 

 head finely punctured ; clypcus scarcely emarginate in front, its 

 suture nearly obsolete ; protliorax minutely punctured, a broad 

 shallow fovea on each side at the base, no groove, the expanded 

 margins not recurved ; scutellum curvilinearly triangular ; 

 elytra flattlsh at the middle and base, finely seriate-punctate, 

 the alternate intervals of the rows raised, the fourth, eighth, 

 twelfth, and sixteenth (the last) much more so than the others, 

 the expanded margins broad at the base, gradually narrower 

 to the apex ; body beneath and legs black, slightly glossy, 

 tibite covered with short spinous hairs ; antennas short, not 

 reaching to the end of the protliorax, black. Length 

 8 lines. 



A very distinct species, in outline resembling P. Reichei^ 

 but the elytra with expanded margins and strongly marked 

 elevated lines, &c. Dr. Howitt merely gives " Interior " as 

 its locality. 



Pterohelceus minimus, 



P. oblongo-ovalis, piceus, subnitidus, marginibus clypeoque pallidio- 

 ribus ; prothorace confertissime oblongo-punctato ; elytris subtu- 

 berculatis, subtiUter et vage punctatis. 



Hah. Cooper's Creek. 



Oblong-oval, pitchy brown, subnitid, the margins of the pro- 

 thorax and elytra, and the anterior part of the head paler, yel- 

 lowish brown ; head densely punctured, the clypeal groove very 

 indistinct ; prothorax rather short, covered with fine oblong- 

 punctures, the intervals very narrow, and in certain lights 

 causing the surface to assume a delicately corrugated appear- 

 ance, the expanded margins narrow and slightly reflected ; scu- 

 tellum transversely triangular ; elytra minutely and irregularly 

 punctured, with scattered minute tubercles, especially near the 

 suture, the expanded margins very narrow ; body beneath and 

 legs glossy reddish testaceous ; antenna? short, inclining to 

 testaceous. Length 3|- lines. 



The smallest species of the genus, and very distinct on ac- 

 count of the sculpture of the protliorax and elytra. I have 

 placed it after Pterohelceus peltatus^ Er., which it resembles in 

 outline. 



The three following are closely allied in general appearance.
