722 NEW specik:s of Australian coleoptera, xiv., 



ones obtuse and not completely rounded off; with rather small 

 but distinct punctures, sparser in middle than elsewhere. Elytra 

 moderately dilated to about the middle: punctures fairly numer 

 ous, except between the geminate strite (these very close together); 

 suture very feebly mucronate. Fygidium shining, lightly con- 

 vex; with rather small, scattered punctures. Basal joint of hind 

 ta7'si distinctly shorter than second. Length, 32 mm. 



Hab. — Western Australia. 



I have had the type for many years under the name of H. 

 gigmitea, but although looking like a large specimen of that 

 species, it may be at once distinguished by the maxillary palpi: 

 on ff. gigaiitea, the antepenultimate joint is slightly longer than 

 the penultimate, hence Blackburn referred it to his Group 5. 

 On the present species, the penultimate is slightly the longer, 

 hence the species must be referred to CC, of his Group 4, and 

 there associated with N. nobilis, from which it differs in having 

 the prothorax more transverse, and the fifth joint of the antennae 

 (instead of the sixth) the first of the club. The rami of the club 

 are decidedly long, but as that of its first joint is only about half 

 the length of the second, the type appears to be a male. From 

 some directions, the pronotum appears to have a fine, iridescent 

 bloom. 



Nova PUS parvus, n.sp. 



(J. Keddish-brown, head and parts of legs black. Under- 

 surface, legs, and upper part of pygidium with dense, rusty-red 

 hair, upper surface glabrous. 



Head with crowded and irregular punctures: with a sharp, 

 short, oblique, simple horn. Antennae ten-, club three-jointed. 

 Prothorax about one-fourth wider than long, hind angles rounded 

 off, front ones produced and acute, with a large discal excavation, 

 its front part with transverse sculpture; with punctures of 

 moderate size, but very irregularly distributed. Elytra with 

 sutural and lateral striie well-defined, but the others represented 

 by feeble depressions or oblique scratches; punctures small and 

 sparse, but becoming immerous at apex and sides. Pygidiiiin 

 with numerous rather small punctures, becoming larger and 

 crowded at base. Length, 15 mm.
