edge; tarsi with first and fourth joints elongate, the third widely 

 bilobed. 



The ocular lobes would appear to exclude this genus from being 

 allied to Myllocerus, or even as belonging to the same subfamily, 

 but the genus is quite obviously related to it. Synomus, an apterous 

 genus but certainly allied to Myiiocents, also has ocular lobes, but 

 they are scarcely traceable. The scrobes (except near the insertion 

 of antennae) are shallow and indistinct, and directed towards the 

 lower margin of the eye; immediately above each there is a groove 

 (sublateral sulcus) that commences close to the antennae, and dilates 

 so that it terminates at the eye from its upper surface to about its 

 middle. On densely clothed specimens, however, this is not always 

 traceable. Generally, however, a fine carina that separates it from 

 the true scrobe can be seen. Above the sublateral sulcus generally 

 another one can be traced. The scape, when resting in the scrobe, 

 extends almost to the middle of the prothorax. 



538. HACKERIA VIRIDIVARIA n. sp. 



Black. Upper surface with green and black scales, lower surface 

 with greenish scales, becoming more or less greyish along middle. 

 Elytra with long and more or less erect setcC, black amongst the 

 black scales, white amongst the green; elsewhere with much 

 shorter setae. 



Head with a narrow and generally concealed interocular impres- 

 sion. Rostrum shallowly depressed along middle, in middle with a 

 very narrow and usually concealed carina, a more distinct one 

 towards each side. Scape distinctly curved, about the length of the 

 six following joints combined; first joint of funicle distinctly longer 

 than second, second than third, and third than fourth. Prothorax 

 about once and one half as wide as long, sides gently and evenly 

 rounded, base slightly bisinuate, but (owing to elytra) apparently 

 deeply bisinuate, with fairly large and deep, but more or less con- 

 cealed punctures. E/^yfra about once and one half the width of pro- 

 thorax at base, sides dilated to beyond the middle, and then strongly 

 and evenly rounded; striate-punctate, punctures rather large 

 (larger in male than in female), but partially concealed. Femora 

 acutely dentate. Length (including restrum) 4-6 mill. 



Hab. : Queensland, Coen River (H. Hacker). 



This species is one of the most beautiful of the many beautiful 

 insects captured by Mr flacker in North Queensland. In some 

 respects it is close to the description of Myllocerus chrepideits, but 

 the ocular lobes are quite distinct, a character which removes it 

 from Myllocerus altogether.
