Remarkable by the punctures of its pronotum very con- 

 spicuously finer and closer than those of its elytra. In this 

 respect it resembles H. Rothei, Blackb., which is a consider- 

 ably smaller species, with the hind angles of the prothorax 

 though well defined notably less sharp than in H. nudus, the 

 hind femora very differently sculptured, etc. The trilobed 

 outline of the head is strongly defined and divided, the middle 

 lobe about half of a lateral lobe in size.

H. impar, sp. nov. Modice elongatus, postice minus dila- 

 tatus ; sat nitidus ; niger, antennis (harum flabello 

 testaceo), palpis pedibus corporeque subtus dilutioribus ; 

 supra fere glaber ; clypeo sat crebre ruguloso, antice late 

 vix emarginato ; labro clypei planum superanti ; capite 

 antice (a tergo oblique viso) tripliciter convexo (parte 

 mediana quam laterales paullo angustiori) ; fronte sat 

 fortiter minus crebre nee rugulose punctulata; hac 

 clypeoque ut plana valde disparia visis ; antennis 9- 

 articulatis, articulo 3° quam 4 US paullo longiori; pro- 

 thorace quam longiori ut 8 ad 5 latiori, antice sat for- 

 titer angustato, supra sparsim subtiliter punctulato 

 (puncturis circiter 12 in segmenti longitudine), lateribus 

 (superne visis) pone medium sat fortiter rotundato- 

 dilatatis, sulco laterali sequali, angulis anticis sat acutis 

 modice productis posticis (superne visis) rotundatis, basi 

 vix sinuata, margine basali subtili sat sequali; elytris 

 fortius minus crebre punctulatis (trans elytron puncturis 

 circiter 23); pygidio longitudinaliter carinato, fortius 

 sparsius punctulato ; coxis posticis quam metasternum 

 sat multo brevioribus, quam segmentum ventrale 2 ura 

 paullo longioribus ; tarsorum posticorum articulo basali 

 quam 2 US sat breviori, 3° sat sequali ; unguiculis posticis 

 append iculatis, parte basali quam apicalis multo longiori.

The punctures of the pronotum very much finer and less 

 close than of the elytra, will distinguish this species from all 

 others (known to me) resembling it structurally. Its small 

 size and dark colour (if the colour is constant) are also very 

 distinctive. The trilobed outline of the head is feebly defined, 

 not divided, the middle lobe fully three-quarters of a lateral 

 lobe in size. 



North Queensland (Mr. Perkins). 



H. hirsutus, sp. nov. Minus elongatus, postice leviter dila- 

 tatus ; sat nitidus ; ferrugineus ; supra (prsesertim in 

 elytris et pronoti margine antico) pilis sat elongatis 

 erectis vestitus ; clypeo (hoc antice late emarginato)
