tibiae simple, basal joint of four front tarsi much less inflated^ 

 and antennae not conspicuously paler between the eighth joint 

 and apex. 



Hah. — Queensland: Brisbane (A. J. Coates, R. Illidge^ 

 A. J. Turner), Dalby (Mrs. F. H. Hobler), Mount Tam- 

 bourine, Rockhampton (A. M. Lea). Type, I. 3275. 



Some males have the upper-surface slightly paler than the 

 under, but usually much darker ; on females the body parts are 

 sometimes almost black ; on the males the knees are slightly 

 infuscated, on the females they are usually deeply infuscated, 

 and some have the legs almost entirely dark. The inflated 

 joints of the male tarsi, although large, are much less con- 

 spicuous than on the preceding species. Each of the prosternal 

 episterna, when viewed from behind, appears to have its 

 front margin gently rounded ; from above it appears to be 

 straight in an oblique direction, and from in front (with the 

 head removed) it appears to be gently concave. Similar com- 

 ments might be made about many other species of the sub- 

 family. 



COLASPOIDES BICARINATA, U. Sp. 



o . Brassy-green ; under-surface castaneous, appendages 

 flavous. 



Head uneven between eyes, with fairly large punctures 

 there, becoming smaller and denser on clypeus and much 

 smaller elsewhere ; with a strongly defined but not continuous 

 median line. Antennae long and thin, second joint about half 

 the length of third, the latter somewhat shorter than fourth, 

 eighth wider than the adjacent ones. Frothoraoc and elytra 

 with smaller punctures, but otherwise much as on tarsalis. 

 Flanks of 'pro8tern\ini almost or quite impunctate. Fourth 

 segment of abdomen with a very consj)icuous carina from base 

 to apex towards each side ; fifth much shorter than fourth 

 and somewhat irregularly depressed. Legs much as in pre- 

 ceding species. Length, 5|-7^ mm. 



9 . Differs in having the abdomen simple, and in the 

 tibiae and tarsi. 



Hah. — New South Wales : Tweed and Richmond Rivers 

 (Macleay Museum, R. Helms, and A. M. Lea). Type, I. 3274. 



Very distinct by the abdomen of the male. The females 

 are usually less metallic than the males ; the tip of the 

 antennae is usually lightly infuscated. Some specimens appear 

 to have the head almost impunctate between the eyes and on 

 the clypeus, but on others the punctures, at least those beween 

 the eyes, are fairly coarse. A small, pale, almost non-metallic 

 female, from Mount Tambourine, probably belongs to this 

 species.
