The pruinosity in some lights make the surface appear of a 
bluish-white colour. The puncturation of the upper surface is 
almost uniform, being slightly at its coarsest on the clypeus, and 
at its finest on the prothorax. The clypeus has a well-defined 
even reflexed mai’gin, and is nearly evenly rounded in front, very 
slightly truncate; it forms an even surface with the rest of the head 
and its suture is feebly marked and slightly arched. The pro- 
thorax is slightly more than half again as wide as it is long down 
the middle 3 it is widest close to the base, which is about half 
again as wide as the front margin 3 the front is strongly emar- 
ginate, the anterior angles being acute 3 the sides are divergent in 
a slight curve from the front almost to the base, where they form 
a roundly obtuse angle with the basal margin which is rather 
strongly lobed hindward in the middle. The elytra have no fringe 
at the apex, and are about three times as long (and at their widest 
])art nearly half again as wide) as the prothorax. They and the 
prothorax are irregularly studded with large punctures, the front 
edge of which is raised in a granuliform manner and from which 
a vei’y long, coarse, red seta protrudes (the longest of these sette 
are more than half the length of the prothorax). On the under- 
side there is a transverse line on the middle (longitudinally) of 
ventral segments 2-5 formed of strong bristles rising from granules, 
the bristles being more than half as long as the segment and very 
stout 3 these rows of bristles commence at the lateral margin and 
run out to near the middle of the segment, but entirely fail on the 
central portion. The hind coxae are very little shorter than the 
metasternura on its external margin, and almost entirely overlap 
the Vjasal ventral segment. Hind femora much wider than the
