Hub. Cheltenham, Victoria {French). The ? (=:type) is 

 177 and the male 178 in the Froggatt collection. 



Known by the tuberculate postscutellum, but otherwise 

 closely allied to the P. versicolor group. From P. tubtr- 

 culatus, P. frontalis (Sm.) differs by the smaller size, 

 antennae testaceous beneath, pale tibial seopa (shining 

 golden above), and in the bright ferruginous mandibles of 

 the male. The face of male frontalis is densely covered 

 with hair; in male tuberculatus it is densely covered only at 

 the sides. P. versicolor differs by the smooth and shining 

 thorax, '' with distant fine punctures/' and the " silken 

 gloss " of the abdomen. P. providus differs by the sparingly 

 punctured thorax and the Avhite tibial scopa. P. obscuri- 

 2iennis (c?) diffeis by the darker wings and the sparsely 

 punctured mesothorax (this is, howevei', more sparsely 

 punctured in ,^ than $ tuberculatus) ; also in the venation 

 and the base of the metathorax. 



Paracolletes tuberculatus insularis, subsp. n. 

 ? . — A little smaller and less robust than the type ; 

 underside of labrum with much copper-red hair ; mesothorax 

 more shining and less densely punctured ; area of meta- 

 thorax with the transverse striae feeble, scarcely evident; 

 thorax above with some dark hair ; first abdominal segment 

 more sparsely, feebly punctured ; hind tibial scopa with 

 black hair behind to apex ; hair on inner side of hind basi- 

 tarsi fuscous. The postscutellar tubercle^ though short, is 

 quite sharp.
