indistinct punctures. Elytra with dense punctures, sparser and 

 smaller, on l)lue basal marking than elsewhere. Length, i\ to 4^ 

 mm. 



2 Differs fi'om the male in having the two basal joints of anten- 

 nae simple, and the front tarsi different. 



Uah. — Queensland : Cairns, Chillagoe (Henry Hacker). 



A medium-sized species, with distinctive elvtral markings, and 

 with the second joint of antennae of male very different to that 

 of any previously-described spec-ies. 



The pale colours have altered somewhat since the specimens were 

 first received, and, unfortunately, they were not noted when fresh. 

 On the ehi:ra the flavous parts appear to be of two shades of colour, 

 both being paler than the prothorax. The subapical fascia, if such 

 it can be called, on the elytra, starts from the sides, where it is 

 widest, and its front margin is angularly produced at its middle, 

 whilst its back margin is triangularly or semi-circularly notched. 

 The basal joint of the antennae is large, and towards its apex has 

 a small conical projection crowned with a seta ; the second is longer 

 than the first, and its extreme width greater than its length, its 

 lower surface convex, and upper irregularly concave, and it has 

 two curious projections from the front ; the anterior one of these 

 is the larger, is first directed outwards, and then backwards, and 

 terminates in a somewhat curved process, which almost, but 

 not quite, touches a narrow process that represents the outer 

 part of the posterior projection. From some directions the two 

 projections appear to meet in front of a circular opening. The 

 male has the second joint of the front tarsi very small, so that at 

 first the tarsi appear to be four-jointed; in the female the second 

 is of normal size, so that the five joints are clearly visible, and the 

 tarsi appear to be longer. 



Laius C.-pupiiretis. n.sp. (Plate XXIT., Fig 10.) 



<r Flavous, basal half of head black, with a purplish gloss, 

 scutellum black; a large spot on each shoulder, and a C-sliaped 

 mark near the apex, deep metallic blue or purple; meso and metas- 

 ternum black with a purplish or metallic green gloss; tip of abdo- 

 men infuscate; four hind legs black with a purplish gloss, the front 

 ones, except tibiae, flavous; two basal joints of antennae and part 

 of third flavous, the rest black. With rather long, suberect, pale 

 pubescence, and, in addition, with some longer and usually darker 

 hairs.
