DITROPIDUS PUNCTICOLLIS sp. nov. 



d lUack, upper-surface witli a slit^lit bronzy gloss, basal half of antennae 

 (except upper-surface of first joint) obscurely diluted with red. Under-surface 

 and legs sparsely pubescent. 



Head shagreened and with small punctures ; clypeus shining and almost 

 inii)unctate. Eyes rather close together. Protliora.v at the base not quite twice as 

 wide as the median length, sides strongly narrowed to apex ; with very small 

 and inconspicuous punctures in middle, becoming coarse on sides. Elytra rather 

 shiirt, sides rather strongly narrowed posteriorly; with rows of rather strong 

 punctures, on the sides set in ileep striae, the interstices between which are costi- 

 forni. Front leys slightly longer than hind ones. Length ( o $ ), 2 '5-3 mm. 



9 Differs in being more robust, eyes more apart, elytra less narrowed 

 posteriorly, front legs no longer than hind ones, abdomen larger, more convex, 

 more sparsely clothed on middle of basal segment, and with a large apical fovea. 



Hub. New South Wales: Blue Mountains (Blackburn's collection) ; Sydney 

 (Dr. E. W. Ferguson). Type, I. 10911. 



The labrum is sliining black, on almost all other dark species it is conspicu- 

 ously red, or at least with reddish sides, the antennae at first glance appear to be 

 entirely dark. The distance between the eyes of the male is about equal to tlie 

 length of the basal joint of antennae, in the female of the two basal joints. At 

 first glance the species apjjears decidedly close to D. [^yyidialis. but the prothorax 

 is non-strigose on the front angles, its sides have coarse punctures, and the inter- 

 ocular space is different : it is also close to P. (iiiadratiprniiis. but the prothorax 

 has only \ery minute punctures in the middle; in sonic respects it resembles D. 

 bracliysoiniis on an enlarged scale, but is less metallic with diiferent punctures, 

 and inter-ocular space different. 



DITROPIDUS BREVIS sp. nov. 



d Bronzy, under-surface of basal joint of antennae reddish. Under- 

 surface and legs sparsely clothed, but pubescence longer and denser on middle of 

 basal segment of abdomen than elsewhere. 



Head shagreened and with small dense, asperate punctures; median line well- 

 defined. Eyes about as wide apart as the length of the three basal joints of 

 antennae. Protliora.v abuut twice as wide as the median length, sides strongly' 

 rounded; with small, elongate punctures, frequently becoming confluent on sides, 

 lilytra along suture less than the basal width ; with rows of rather strong punc- 

 tures, on the sides set in deep .'^triae ; interstices with very minute punctures. 

 Abdomen with a small and shallow, l)ut distinct, apical fo\ea. Let/s rather stout, 

 front ones distinctly longer than hind ones. Length, 3-3 25 mm.
