antennaR. Second joint of the fljii^tilliini equal to the thinl, at 

 least three times as long as the tir.st. Eyes separated on the 

 vertex by a distance sli:^htly greater than the length of the 

 second joint of the Hagelinm. Pronotnm depressed below 

 the niesonotuni, a little higher in the middle than at the sides, 

 very sharply sloped. Mesoiiotuni and scutelliun shining and 

 smooth ; pleurie opaque, ahno.st smooth. Median segment 

 smooth, opaque, without a median line, as long as bioad, t!iO 

 posterior slope transversely striated. Abdomen smooth and 

 shining ; pygidial area very long and narrow, with a few 

 minute punctures, the sixth segment as long as the fourth 

 and tifth combined. Fore tarsi stout, the comb short as 

 compared with most species of the genus. The three 

 abscissa? of the radius about equal in length ; first recurrent 

 nervure di.«tinctly nearer to the second than to the first 

 transverse cubital nervure. The tegulse are brown at the 

 apex.

This may be distinguished from other Australian species 

 by the larger size and highly polished appearance. The eyes 

 are closer to each other on the vertex than in hypoleius^ Siu.

? . Clypeus shining, irregularly and rather coarsely punc- 

 tured, convex at the base, the apical half depressed and 

 flattened; apical margin transverse, with two indistinct teeth 

 on each side close to the angles. Front subopaquf, minutely 

 punctured, with an indistinct longitudinal sulcus reaching 

 the anterior ocellus. Eyes separated on the vertex by a 

 distance slightly exceeding the combined length of the two 

 basal joints of the flagellum ; the second joint of the flngellum 

 equal to the third and nearly three times as long as the first. 

 Pronotnm oblique, depressed below the mesonotum, some- 

 what higher in the middle than at the side?. Pleurae and 

 mesonotum subopaque, microscopically punctured ; median 

 segment opaque, as long as the mesonotum, transversely 

 ruguiose-striate, wit^h a shallow longitudinal sulcus from base 

 to apex, the face of the posterior truncal ion more strongly 

 transversely striated, with a deep sulcus from the base not 

 reaching the apex. Abdomen 3uboi)aque above, smooth and
