390 DKSCRIPTIOXS OF XKW SPKCIES OF Al'STHALIAX COLEOPTKRA, 



DiTROPiDUs LAEvicoLLis Lea. 



This species occurs in South Australia (Lucindale and Port Lincoln) as well 

 as in Western Australia. Its elypeus appears as a narrow transvei-se rid^e, and 

 in many other respects it agrees witli the description of D. suhmetaUexcenn, hut 

 all the specimens before me are somewhat larger, 2 — 2.75 mm., than the type of 

 that species. z^Hn., which was also noted as having "thorace subremote, tenuiter 

 piiiictato''; the prothoracic punctures of /;. laevicoUis are certainly not subremote, 

 bi'iiig fairly dense, althougli not crowded. 



DlTBOPIDlS MTKrATOPUXCTATrs Lea. 



A short compact species, the prothorax with sparse and small punctures on 

 the disc, but the sides densely longitudiuall.y strigose. Specimens from Sydney 

 and Galston agree well with the type, except that the legs ai-e entirely black; the 

 eyes of the male are separated rather more than the length of the basal joint of 

 the antennae, still more in the female. 



DiTROPiDUM sOBRixvs Lea. 



Numerous specimens from South Australia (Petersburg, Quorn and Para- 

 <-hilna) belong to this species, but range in lengih 2.25 — 3 mm., the males usually 

 being smaller than the females. The eyes are moderately widely separated in the 

 males, more widely in the females; the jiunctures in the inter-ocular space are 

 i-ather dense and sharply defined; there is usually a well-defined median line there, 

 but occasionally it is almost absent; tlie discal striae of the elytra are very feelile; 

 the labrum is reddish, and the red occasionally extends to tlie elypeus. 



DiTROPiDus VEXUSTUS Lea. 



A specimen from Northern Queensland, and another from Mungar .Junction, 

 <liffer from the types in having the ui)per surface entirely purple, altliough the 

 protliorax is of not quite the same shade as the elytra. 



DiTROPinrs .scitui.tts Lea. 



Of two specimens from the Swan Kivei' one agrees well with the type, but 

 the other has the elytra of a vivid cn|iiiciy-green . 



DiTROPIUUS LATIFRONS, U . SJI . 



^ c?. — Coppery-bronze, in places with a sliglit imriilisii gloss; lal)rum, antennae 

 (the club infuscated) and )ial).)i ledilisli, ti))s of tibiae obscurely reddisli. MckUt- 

 ately densely clothed with white pubescence. 



Head wide and flat in front; witli I'ather dense, partially <'nncertlecl punct\tfes. 

 Eyes widely separated. Prothorax about twdce as wide as the median length, 

 evenly convex, a feeble oblique carina on each hind angle, these acute; punctures 

 rather dense and sharply defined, but not very large. Eli/tra with siunewhat 

 coarser punctures than on prothorax, the interspaces slightly rugose; striae well- 

 detlned on sides, but scarcely traceable elsewliere. Le()S rather stout, 

 the front ones somewhat longer than the otliers. Lenglii (c?. ?), 3.75 — 4 mm. 



?. — Differs in l)eing rather more robust, iiead smaller, labrum less prominent, 

 antennae somewhat thinner, with the club no darkei- than the basal joints, front 

 legs no longer than tlie liind ones, more of tlie tiliiiie reil. ;ind in tlie iiliduineii.
