486 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



the derm; three basal joints of antennae similarly clothed; the 

 others with short setose pubescence of a rather dingy brown; 

 scutellum with black scales; elytra with round stramineous (in 

 places brown) scales covering the interstices, and placed round 

 the fovese in such a fashion as to cause them to appear to be 

 granulate. Under surface uniformly clothed with round muddy- 

 grey scales; tarsi, intermediate tibi?e and posterior legs with soft 

 pubescence of a golden tinge, the legs elsewhere squamose. 



Head (excluding mandibles) transverse ; base widely and 

 shallowly emarginate, a median impression continued from base 

 to between antennae, an impression on each side close to and 

 continued around eyes. Mandibles stout, strong and irregularly 

 punctate. Eyes large, round, prominent, minutely faceted. 

 Antennse terminating before middle of elytra, 1st joint large, 

 -apex oblique, 2nd small, 3rd-llth cylindrical, 3rd feebly con- 

 stricted in middle, slightly longer than 1st or 4th, fully twice the 

 length of 2nd, and equal to 11th, 4th-10th almost equal in length. 

 Pro^Aorax transverse, disc strongl}^ excavated on each side, middle 

 longitudinal raised and keel-like, and with a distinct median line; 

 lateral margins somewhat raised, near apex projecting as an 

 obtuse tooth ; apex narrower than head, the base wider and 

 bisinuate, from some directions appearing to be rounded. 

 ■Scutellum convex, suboblong. Elytra almost four times the 

 length of head and prothorax combined, at base about once and 

 one-half the width of prothorax, near apex fully twice as wide; 

 suture, 3rd, 5th (except at base) and 7th (especially at the 

 shoulders) interstices raised and thickened, the interspaces with 

 ■double rows of large square excavations or foveae, sides oblique 

 and with three uniform rows. Junction of prosternum with 

 pronotum marked by a deep groove; abdomen long, the four basal 

 segments feebly but distinctly trans versel}^ ridged. Legs thin; 

 anterior tibiae strongly, the intermediate feebly, curved; posterior 

 straight. Length 13 J, width 4 J mm.
