Longicornia of Australia and Tasmania. HO 
mediate tibies with a very feeble sinuation on their outer border 
towards the distal extremity. 
This genus, which is represented by one of the smaliest 
species of Longicornia known to me, seems best placed 
towards the end of Lacordaire’s subgroup of the Hxo- 
centrides. Some of its characters point ep an affinity 
with the Cyrtinides. 
62. Allomicrus exiguus, sp. 0. 
Niger, sparsissime setosus; elytris nigro-fuscis; antennis fuscis 
articulorum basibus testaceis; femorum basibus pallide testaceis. 
Long. 2°5, lat. 0°5 mm. 
Hab. Albany, in West Australia (Walker). 
The prothorax is distinctly longer than broad, with the basal 
fourth much narrower than the anterior three-fourths; and with a 
small but distinet conical tubercle near the middle of each side, 
whose posterior border is somewhat longer than the anterior, and 
slopes gradually back to the front end of the basal constriction. 
The upper surface of the prothorax is closely and finely punctulate, 
and is faintly impressed by a transverse groove at about one-fourth 
of its length from the anterior magin. The elytra are dark brown, 
nitid in places, and in other parts exhibiting faint indications of a 
greyish pubescence; they are thickly enough punctured in and 
between the two oblique depressions, which pass back, one on 
each side, from the shoulders towards the sutural region, but else- 
where seem very sparingly punctured. The various parts of the 
body, and the legs and antenne, are very scantily furnished with 
suberect sete.
