Lea— On Austkamax Coleoptera 407 



Head with rather dense ])unctures at base, sparse or irregular elsewhere: 

 median line shallow but distinct. Eyes distant about the length of three basal 

 joints of antennae. Prothora.v scarcely twice as wide as the median length, sides 

 stnmg-ly rounded; with dense and sharply defined but not very large punctures, 

 Ijeconiing slightly smaller on sides. SciitcUuiii thin and rather long. Elytra 

 liricfl\' sulxiblong; with rows of rather small punctures, becoming larger and set 

 in rather deep striae on the sides; interstices with very small punctures. Abdomen 

 with a large, round deep apical fovea. Length, 2 23-2 5 mm. 



Hab. Australia (old collection j : South Australia; Murray Bridge (J. G. O. 

 Tepper), Kangaroo Island (A. M. Lea). Type, L 10907. 



A metallic species with unusually narrow scutellum, it is at least twice as 

 long as wide, and as this is a most unusual feature I have named the species, 

 although there are but females, 6, before me ; the upper-surface is much the 

 colour of D. odewaliiii. but the scutellum. legs, punctures, etc., are different; the 

 outlines are almost as in D. 'I'ciiiistiis ; in general appearance it is close to D. 

 aurkhalceus, but is slightly narrower, prothoracic punctures more sharply defined, 

 sides non-strigose, scutellum narrower and legs dark ; it is apparently close to D. 

 laetus. but differs, from the description of that species, in being larger, and in the 

 sculpture of the prothorax. On one specimen the clypeus, and on another the 

 base of the front femora, are obscurely reddish. 



DITROPIDUS CONGENITUS sp. nov. 



6 Coppery or coppery bronze, basal half of antennae obscurely reddish. 

 L'nder-surface and legs with sparse pubescence. 



Head with dense, sharply defined punctures, median line rather slightly 

 impressed. Eyes moderately separated. Prothorax scarcely twice as wide as the 

 median length, sides strongly rounded; with fairly dense and sharply defined but 

 rather small punctures, no larger on sides than in middle. Elytra very little longer 

 than the basal width ; with rows of fairly large punctures, on the sides set in deep 

 striae ; interstices with very minute punctures. Front legs slightly longer than 

 hind ones. Length (d ? j, 2 -5-2 75 mm. 



9 Dift'ers in being more robust, elytra less narrowed posteriorly, legs some- 

 what shorter, the front ones no longer than the hind ones and abdomen foveate. 



Hab. South Australia; Adelaide (H. H. D. Griffith), Murray Bridge (A. 

 M. Lea J. Type, L 10926. 



In general appearance decidedly close to the preceding species, but scutellum 

 much shorter (of normal size and shape) punctures of head denser and larger, 

 eyes of female more widely separated and labrum almost black; it differs from D. 

 tropicus in its decidedly coppery tone, somewhat longer form and smaller punc-
