208 STUDIES IN AUSTRALIAN ENTOMOLOGY, 



narrowed in front, very rounded behind where the sides are not 

 the least prolonged, and have a shape like that of the first group ;* 

 the angles of the base are hardly distinct. The marginal border 

 is very fine and is not prolonged to the middle of the base. The 

 surface is but little convex, especially in the middle ; the median 

 line reaches the base ; the transverse impressions are well marked, 

 but rather short. The elytra are elongate-oblong, very slightly 

 rounded in the middle ; the shoulders are raised, but very much 

 narrowed externally ; all the striaj, except the seventh, are well 

 marked and finely punctate, becoming more shallow and con- 

 fused towards the apex ; the interstices are a little unequal. 

 The large umbilicate punctures of the lateral margins are bigger 

 than usual. The fovese of the abdominal segments are wide and 

 rounded. The thighs are club-shaped ; the anterior tarsi have 

 the four first joints spongiose below ; the intermediate are very 

 narrow, only clothed on the three first joints ; the last joint of all 

 the tarsi is slender, elongate, and not flattened above."

^. — Black, with a slight bronzy tinge ; palpi, tarsi, and antennae 

 reddish, first joint of antennse not lightei'-coloured than others. 

 Head small, smooth ; lateral impressions of clypeus small, round, 

 deep ; clypeal suture distinct in the middle ; eyes not very 

 pi'ominent ; the post-ocular prominences small. Prothorax short 

 (3 X 3 J mm.), cordate, broader than long, subconvex, flattened along 

 the median line, very declivous on each side to the anterior angles ; 

 sides rounded, shortly narrowed behind ; median line light, not 

 I'eaching either margin, crossed behind by a clearly marked trans- 

 verse impression ; the marginal border very narrow, with a very 

 slight and hardly perceptible sinuosity a little in front of the base, 

 not crossing the middle of the base ; the basal angles well marked,
