the following ones longer and somewhat stouter. Prothorax 

 with evenly rounded sides, with two rather large, shallow, 

 circular depressions about middle towards base ; punctures 

 much as on head. Elytra with numerous rows of well-defined 

 punctures ; many of the interstices distinctly elevated. Fifth 

 segment of ahdomen with a shallow median fovea. Hind 

 tibiae widest in middle, thence strongly narrowed to base and 

 feebly to apex ; basal joint of four front tarsi rather strongly 

 inflated. Length, 2^-2^ mm. 



9 . Differs in having the eyes somewhat smaller and more 

 distant, abdomen non-foveate, hind tibiae thinner and feebly 

 increasing in width from base to apex, and basal joint of four 

 front tarsi much smaller. 



Hab. — Queensland: Cairns district (Macleay Museum, E. 

 Allen, and A. M. Lea). Type, I. 3406. 



An abundant species in the Cairns district. The upper- 

 surface, whilst always metallic, is seldom brightly so ; the 

 main colour is usually brassy-green, but sometimes brassy or 

 bronzy. On the elytra the margins are nearly always con- 

 spicuously bluish, and there are bronzy or obscure purplish 

 markings, sometimes in the form of large obscurely defined 

 spots, but frequently confined to some of the elevated parts, 

 occasionally there is an ill-defined bluish spot on the disc of 

 each. The prothorax varies from entirely brassy-green to 

 almost entirely bronzy, but the two colours are usually 

 obscurely mingled ; the head is usually more obscurely metallic 

 than the prothorax ; the palpi are nearly always pale-flavous, 

 and the knees are sometimes lightly infuscated. Many of the 

 rows of elytral punctures are short ; about the base the striae 

 are not well impressed, but posteriorly they become very 

 evident owing to the greater elevation of the interstices ; many 

 of these are oblique owing to the brevity of some of the rows ; on 

 each elytron there are three interstices that are more con- 

 spicuously elevated than the others, but their respective 

 positions vary, thus (counting the sutural interstice as the 

 first) across the middle they are the fifth, eighth, (^5) and 

 tenth, but towards the base they become the seventh, eleventh, 

 and fourteenth, and at summit of apical slope the third, 

 fifth, (96) and seventh. Each of the circular depressions (they 

 could scarcely be regarded as foveae) on the pronotum is about 

 thrice the length of the scutellum ; although not deep, they 

 are usually quite distinct. 



<^95) Between the fifth and eiejhth for some distance alongj the 

 middle tlic other interstices are sometimes almost or quite as 

 strongly elevated. 



(96) This one rather abruptly ends on the slope itself.
