several feebly elevated on subtuberculate spaces about middle, 

 the interspaces with numerous small punctures. Elyira con- 

 siderably wider than prothorax ; with numerous rather large 

 punctures, in places seriate in arrangement, but with numerous 

 transverse irregular ridges or costae, on most of basal two- 

 thirds, on apical third with series of small depressed tubercles, 

 •or large granules of irregular shapes. Flanks of prnsier- 

 num with numerous punctures, but partially concealed by 

 clothing. Fifth segment of abdomen with a rather wide 

 shallow basal depression. Legs stout ; femora, edentate ; tibiae 

 dilated at apex and with many acute ridges; basal joint of 

 front tarsi strongly dilated. Length, 5-7J mm. 



9 . Differs in having the abdomen more strongly and 

 evenly convex, non-foveate, and in the front tarsi. 



Hab. — Queensland (H. J. Carter); Northern Queensland

In general appearance fairly close to carinatus, but 

 striation less pronounced posteriorly, and transverse sculpture 

 of elytra towards base quite evident and strong, more con- 

 spicuously clothed, etc. ; the interstices on carinafus, micans, 

 and porosus on the apical slope are usually entire, although 

 somewhat undulated, but on the present species they are 

 broken up into series of granules or small tubercles. The 

 metallic gloss is always conspicuous on the head, prothorax, 

 and base of elytra, the scutellum and the subtuberculate parts 

 of the pronotum are nearly always purplish ; on the male the 

 upper-surface of the head frequently appears to be brassy, 

 without a trace of the castaneous colour showing ; the antennae 

 are usually somewhat paler than the legs, the latter are some- 

 times feebly infuscated in places. On the elytra the pubescence, 

 although distinct, is confined to the depressed parts. The 

 median impression on the head is usually distinct, but is 

 occasionally rather feeble ; on some specimens it becomes almost 

 subfoveate towards the base. Two specimens from Mr. 

 French were sent as from Roebuck Bay (North-western Aus- 

 tralia). 



Alittus macleayi, n. sp. 



c? . Flavous or castaneo-flavous, in places with a bright 

 metallic gloss; suture infuscated. Head, prothorax, and 

 under-surface with short, and not very dense, silken pub- 

 escence, tip of elytra very feebly clothed. 



Head with dense and rather small punctures ; with a 

 distinct impression along middle, and with a small polished 

 impunctate space near each antenna. Second joint of 

 antennae less than half the length of third. Prothorax with
