Head with two small but distinct interocular impres- 

 sions. Antennae moderately long and not very thin, three 

 apical joints distorted. Prothorax about twice as wide as 

 long, distinctly margined throughout. Elytra parallel-sided 

 to near apex; with dense and small, but sharply defined 

 punctures, becoming somewhat larger about middle. Length, 

 4 mm. 



Hab. — Victoria : Dividing Range (Blackburn's collec- 

 tion). Type (unique), I. 11868. 



The seventh and eighth joints of antennae are slightly 

 incurved on one side, and outcurved on the other, the ninth 

 has a narrow notch near the base (invisible from most 

 directions, but very distinct from others), the tenth has its 

 apical portion hollow, and conspicuously produced on one 

 side, and a subbasal notch somewhat larger than on the 

 ninth, the eleventh is about as long as the two preceding 

 combined, with a spine on one side of base, and the middle 

 strongly incurved on one side. There are two small, round 

 foveae, on the disc of the pronotum of the type; they are 

 quite symmetrical, but their presence is possibly due to post- 

 mortem contractions. No parts of the legs (except a small 

 portion of the front coxae) are flavous, even the tibiae being 

 deeply infuscated. In my table would be placed with 

 H. gagaticeps, which has conspicuously bicoloured legs and 

 very different antennae; it is closer to H. laticollis than to 

 any other described species, but the scutellum is dark, the 

 apical joint of the antennae is less strongly curved than on 

 that species, but in much the same way.

o* . Black; prothorax flavous, parts of three basal joints 

 of antennae obscurely flavous. With rather dense pubescence. 



Head with scarcely traceable frontal impressions. 

 Antennae moderately long, third joint stouter than the others, 

 tenth and eleventh distorted. Prothorax twice as wide as 

 long, margined throughout. Elytra parallel-sided to near 

 apex ; with dense and small, sharply defined punctures, 

 becoming larger about middle. Length, 3'25-3*5 mm. 



Hab. — Tasmania: Cradle Mountain (H, J. Carter and 

 A. M. Lea). Type, I. 12209. 



The tenth joint of antennae on one side is slightly longer 

 than the ninth, but on the other is conspicuously shorter, the 

 eleventh has one side incurved towards the base, with the 

 base itself on that side produced over the shorter side of the 

 tenth, and with a small spine there. The abdominal notch is 

 larger than usual. In my table would be placed with H.
