COLASPOIDES HERONI, n. Sp. 



d . Brassy-green ; under -surf ace castaneous, appendages 

 flavous, but four apical joints of antennae and part of seventli 

 black. 



Head uneven between eyes, with dense and rather coarse 

 punctures there, becoming smaller and denser on clypeus, and 

 much sparser and smaller elsewhere; median line well defined. 

 Antennae rather long and thin, second joint slightly more 

 than half the length of third, the latter distinctly shorter than 

 fourth. Prothorax with large, irregularly distributed punc- 

 tures, sometimes becoming crowded on sides. Elytra with 

 somewhat smaller punctures, but otherwise much as on tarsalis. 

 Flanks of prosternum with a few scattered punctures. Fourth 

 segment of abdomen somewhat irregularly transversely elevated 

 in middle; fifth somewhat shorter than fourth, rather widely 

 foveate in middle. Legs much as on picticornis. Length, 

 5J-6 mm. 



9 . Differs in having thinner antennae, more convex and 

 simple abdomen, and in the tibiae and tarsi. 



Ilab. — New South Wales: Dorrigo (W. Heron); Queens- 

 land: Killarney (H. H. D. Griffith, from R. Illidge). Type, 

 I. 3277. 



On some specimens parts of the under-surface are deeply 

 infuscated, as occasionally are parts of the legs. 



COLASPOIDES ELEGANTULA, U. Sp. 



PI. viii., fig. 160. 



d" . Brassy-green ; under-surface reddish-castaneous ; 

 appendages flavous, but four apical joints of antennae 

 blackish. 



Head irregular between eyes, and with some fairly large 

 but irregular punctures there, elsewhere much smaller and 

 sparser; with a small, impunctate, elevated space near each 

 antenna. Antennae long and thin, second joint not half the 

 length of third, the latter equal to fourth. Prothorax with 

 irregularly distributed and sparse, comparatively small, but 

 sharply defined punctures. Elytra with punctures of moderate 

 size, becoming larger, crowded, and more or less confluent 

 behind shoulders, smaller and in almost regular striae on 

 apical slope, and in semi-double rows elsewhere. Flanks of 

 prosternum with a few scattered punctures. Abdomen de- 

 pressed along middle, third, and fourth segments, each with 

 a median ridge, the fourth transversely depressed across apex, 

 and twice as long as third, fifth short and irregularly im- 

 pressed. Front femora acutely dentate ; hind tibiae rather 

 feebly dilated on apical half ; basal joint of four front tarsi
