punctures rather dense and small but sharply defined, 

 becoming slightly larger and denser on sides. Elytra 

 suboblong; with rows of not very large but distinct punctures, 

 on the sides set in fairly deep striae ; interstices with dense and 

 minute punctures, or faintly shagreened. Hind margin of 

 intercoxal process of 'prosternum almost truncated. Length 

 {S , 9), 2-5-3 mm. 



9 . Differs in being more robust, eyes slightly more 

 apart, antennae less distinctly six-jointed, legs somewhat 

 shorter, and abdomen with a large apical fovea. 



Hah. — Australia (Blackburn's collection); South Aus- 

 tralia (Macleay Museum). Type, I. 10965. 



In general appearance strikingly close to Ditro'pidus 

 nigrihasis, and with prothoracic sculpture very similar, but 

 the mazzle, owing to the clypeus (which scarcely varies 

 sexually), is almost twice as long as on that species, and the 

 club is distinctly six- jointed on the male, but on the female 

 the sixth joint of the antennae might be regarded as 

 belonging either to the club or to the basal portion. On one 

 specimen the scutellar lobe appears to be feebly notched, but 

 on six others it is not. The black parts of the head cause 

 the eyes, at first glance, to appear much larger than they 

 really are; the red middle part extends to the extreme base 

 and is wider on some specimens than on others; the elytral 

 punctures are more conspicuously infuscated on some 

 specimens than on others. 



Var. A male, from New South Wales, has three black 

 spots on the prothorax : a large medio-apical one, and a 

 smaller one on each side, the three narrowly connected , across 

 the apex; most of its head is also black; the apical joint of 

 its antennae is longer, and the curved apical portion narrower 

 and more distinct; as the curious muzzle, however, is as on 

 the other specimens, it probably does not represent more than 

 a variety.
