Mr. G. R. Waterhouse’s Descriptions 
Obs.— This species is evidently allied to the last described, 
having the same short antennae, with the terminal joints incras- 
sated ; the hinder tibiae also, as in H. crassicornis, are curved 
downwards. It is remarkable for its short and almost perfectly 
oval form, and its great glossiness. To the naked eye it appears 
to be devoid of sculpturing, but with the assistance of a tolerably 
powerful lens we perceive that the head, thorax and elytra are 
very delicately punctured. 
Species 3. H. substriata. 
II. longe ovata, testacea; antennis brevibus, capite et thorace 
impunctatis, hoc fovea transversa leviter impresso, prope 
basin ; elytris vix punctato-striatis ; femoribus posticis lon- 
gioribus, corpore subtus piceo.

Obs. — This species, like the preceding, would appear at first 
sight to belong to the genus Macronema. The antennae are mo- 
derately thick at the apex. 
Species 4. II. acuminata. 
H. longe ovata, ochracea, corpore supra laevi ; elytris versus 
apicem acuminatis ; capite, thorace, suturaque fulvo tinctis ; 
corpore subtus, femoribusque posticis fulvis.

Llabitat King George’s Sound. 
Obs. — This species is very closely allied to the preceding : it 
may, however, be distinguished by the fulvous tint of the body 
beneath, its different form, and its smooth upper surface, there 
being no traces of striae on the elytra ; there is a very faint trans- 
verse impression on the posterior part of the thorax. 
Species 5. H. bicolor. 
H. ovata, nitide aeneo-viridis ; thorace, capite anteriore, anten- 
narumque basi, testaceis ; corpore subtus, pedibusque nigris ; 
tibiis tarsisque piceo-testaceis ; antennis mediocribus ; thorace 
linea transversali, foveisque duabus longitudinalibus, postice 
impresso ; elytris punctato-striatis.
