740 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xiv., 



general outlines of the prothoi-cax and elytra are much as figured 

 for those of Phcenocerus subdavatus (Bonv., Mon., PI. xiii., fig.l). 

 On one specimen, the eighth and ninth joints of each antenna 

 appear to be combined to form but one (with the suture com- 

 pletely obliterated in places); but, as the antennae of the type 

 are normal, this would appear to be accidental. On this speci- 

 men, also, there is a short, shining, median line, and two, small, 

 medio-discal fovese on the pronotum (quite absent from the type). 



Ph^nocekus clavicornis, n sp. 



Black, antennae and legs somewhat obscurely diluted with red, 

 tarsi paler. Rather densely clothed with short, ashen pubescence. 



Head with small, crowded, partially concealed punctures, inter- 

 antennary carina not continued across middle. Antennae stout 

 and not very long, first joint as long as the three following com- 

 bined, second short, third slightly longer than fourth and fifth 

 combined, fourth slightly longer than fifth, fifth-eighth short and 

 transverse, ninth-eleventh forming a conspicuous club, ninth and 

 tenth each conspicuously wider and longer than eighth, eleventh 

 as wide as tenth at ba^se, but rapidly narrowing to apex. Pro- 

 thorax with sides strongly rounded in front, thence parallel-sided 

 to base, with a slight but almost continuous median line; with 

 dense and rather small, but sharply defined punctures, becoming 

 crowded on sides. Elytra feebly diminishing in width from near 

 base ; densely granulate punctate about base, elsewhere with 

 small but sharply de6ned punctures; striation well-defined 

 throughout. Hind coo:(e at sides about one- third their greatest 

 length, this slightly more than that of second abdominal seg- 

 ment; basal joint of hind tarsi about as long as the two apical 

 joints combined. Length, 1\ mm. 



Hab. — Tasmania: Hobart (A. M. Lea); unique. 



The antennae have a distinctly three-jointed club, a character 

 which excludes the species from all the genera noted by Bon- 

 vouloir, except Phceuocerus; but the club is even more distinct 

 than as figured for P. subdavatus; from the description of that 

 species, also, it differs in being somewhat smaller, much darker, 

 and prothorax with a conspicuous median line. In Blackburn's
