Hah. — Western Australia : Greraldton (Blackburn's 

 collection from E. Meyrick). Type, I. 10910. 



A small wide species, in some respects close to the 

 description of duhoulayi (also from Geraldton), but elytra 

 not ''viridiaeneis," being of the same colour as the 

 prothorax, the legs are also entirely dark, and the head is 

 not "remotely punctured," being densely punctured and 

 shagreened. The distance between the eyes of the male is 

 about equal to the length of the two basal joints of antennae, 

 in the female it is about one-third more. 



C , 3. Minute species, usually entirely glabrous. 



DiTROPIDUS ROTUNDIFORMIS, U. Sp. 



(S . Black with a slight or moderate bronzy gloss, basal 

 half of antennae flavous, the club infuscated, labrum and 

 parts of front legs obscurely diluted with red. Glabrous. 



Head shagreened and with minute punctures; median 

 line lightly impressed. Eyes rather widely separated. 

 Prothorax about thrice as wide as long, sides strongly 

 rounded; with dense and fairly large, sharply defined 

 punctures. Elytra scarcely as long as the basal width, sides 

 beyond middle strongly rounded; with series of small punc- 

 tures, becoming larger and set in deep striae on sides. Sterna 

 with dense sharply defined punctures. Length (d, 9)> 

 1-75-2 mm. 



9 . Differs in having eyes slightly more apart, legs 

 slightly shorter, and abdomen foveate. 



Hah. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 10916. 



A small round species, although quite an ordinary looking 

 member of the genus so far as the outlines and punctures are 

 concerned (these being much as those of venuStus and 

 caeruleus); punctuliim is much smaller, and with the 

 prothorax shagreened instead of strongly punctate. At a 

 glance all the legs appear to be black, and the dilution of 

 parts of the front ones (sometimes the apical portion only of 

 the tibiae) is not very pronounced on any of the specimens 

 (six) before me. 



DiTROPIDUS RIVULARIS, U. Sp. 



d. Black; clypeus, labrum, mandibles, basal half of 

 antennae, palpi, and parts of legs flavous (sometimes rathej 

 obscurely so). Glabrous. 



Head opaque and apparently impunctate; median line 

 scarcely defined. Eyes widely separated. Prothorax opaque 

 (less so in middle than elsewhere), more than thrice as wide
