Head with a vague, curved depression, with in-eg^ilarly distributed punc- 

 tures. Antennae rather short, third to tenth joints strongly serrated. Prothorax 

 about as long as tiie greatest width (almost across exact middle), angles rounded 

 off, base no narrower than apex, a very shallow depression near base, with a 

 few scattered punctures. Elytra about thrice the length of prothorax, with dense, 

 mgose punctures. Length, 4.5 mm.

The elytral punctures, although of fairly large size, are so rugose that very 

 few are sharply defined. At first glance the species seems close to C. bifoveatus, 

 but the elytra are of a brighter and more metallic blue, and with the punctures 

 more coai'sely rugose; there are also differences of colour in the abdomen and 

 legs. In my table it would be placed with C. rhagonychinus, C. simulator, and 

 pai't of C. variipennis, but rhagonychinus is now known to be a Balanophorus, 

 which the present species certainly is not, as its front tai'si are combless, and 

 they are comb-bearing in both sexes of that genus; the other species are very 

 differently coloured and punctured. 



Carphurus opacipennis, n. sp. 



c?. Of a dingy flavous; tip of eleventh joint of antennae, a rather large 

 spot on each elytron, mesosternum, metasternum, parts of under surface of four 

 basal segments of abdomen, and hind coxae infuscated or black. With very 

 short, whitish pubescence; a few long hairs scattered about, but not on prothorax 

 and elytra. 



Head rather long, gently convex between eyes, somewhat uneven in front; 

 with minute punctui'es, becoming more distinct behind eyes; base transvereely 

 strigose. Antennae long and thin, very feebly serrated. Prothorax distinctly 

 longer than wide; sides strongly rounded and widest at apical third, a shallow 

 depression near base; punctures inconspicuous. Elytra opaque, about twice the 

 length of prothorax, with crowded but sharply defined punctures. Basal joint ot 

 front tarsi large, lopsided, with a narrow black comb on inner edge from near 

 base to apex, around which it curves. Length, 6.5 mm.

The elytra are of a darker shade of colour than the other parts, the large 

 spot on each is somewhat rounded, nearer the side than the sutui-e, and at about 

 the apical third ; the shoulders are also slightly infuscated ; their opaque sur- 

 face, with dense punctures, causing the surface to appear finely granulated or 

 shagreened, render the species a very distinct one. In my table it would be as- 

 sociated with C. frenchi, with which it has few details in common. 



Helcxxjaster obliquicePiS Lea. 



A male of this species, from Jenolan (New South Wales) differs from the 

 type in having the head almost entirely dark, the muzzle being, at most, obscurely 

 diluted with red on the sides; the dark parts are also more intensely black than 

 on the type. 



Helcogaster macdliceps Lea. 



A male of this species in Mr. H. J. Carter's collection, from Illawarra, has 

 a small black spot on the disc of the prothorax, five of the abdominal segments 

 black except at the tips and sides, and all the femora black on the basal half.
