length of the second and third joints is rather more than 

 that of the fourth, but the third is conspicuously shorter than 

 the fourth. The size ranges from 6| to 12 J mm. The type 

 was recorded as from New Holland. The specimens before^ 

 me are From New South Wales (Dorrigo and Bellingen). 



Hemiopsida ventralis, n. sp. 



Castaneous ; head, pronotum (a large discal patch 

 excepted), part of sterna, and basal joint of antennae, black 

 or blackish. Rather densely clothed with whitish pubescence. 



Head with crowded punctures of moderate size; a sub- 

 foveate impression between anteniiary sockets ; clypeus widely 

 depressed in middle. Antennae extending to about one-fifth 

 from apex of elytra, second joint very short, third to tenth 

 moderately serrated, third slightly longer than first or fourth, 

 fourth-tenth subequal in length, eleventh almost as long as' 

 ninth and tenth combined. Prothorax with sides obliquely 

 and almost evenly increasing in width to base, with an 

 irregular shining median line on basal half ; with punctures 

 much as on head. Elytra parallel-sided to beyond the 

 middle ; with rather small but dense and irregular punctures, 

 becoming crowded about base ; striation rather lightly im- 

 pressed, but becoming deep posteriorly. Abdomen with a 

 wide and deep impression on each side of middle. Length, 

 6^ mm. 



Hah. — Queensland: Cairns district (A. M. Lea). Type 

 (unique), I. 5744. 



The depression on each side of the abdomen commences 

 about the middle of the first segment, and terminates at the 

 tip of the third, its inner wall is almost vertical ; at first 

 glance the depressions appear to be due to irregular contrac- 

 tions, but they are alike on both sides ; they are wider than 

 on longicornis, commence and end sooner, and are much less 

 conspicuously clothed. The second joint of the antennae is 

 paler than the following ones ; the pale portion of the pro- 

 notum is almost circular in outline. 



Hemiopsida mediana, n. sp. 



Deep-black, tarsi obscurely reddish. Moderately clothed 

 with short stramineous pubescence. 



Head densely granulate-punctate, with a shallow depres- 

 sion between anteniiary sockets and another on clypeus. 

 Antennae extending to about middle of elytra, second joint 

 very short, third slightly shorter than first, and slightly 

 longer than fourth, fourth-tenth subequal in length, eleventh 

 distinctly longer. Prothorax rather strongly convex, sides 

 gently rounded, hind angles acute and clasping shoulders,
