situate at about a third from the base, and midway between side 
and suture; the second lunulate, situate at about a fourth from 
apex, not quite touching side or suture; abdominal segments in 
some lights appearing wholly ferruginous, in others only their 
apices, basal joints of antenna?, palpi and legs brownish- testaceous. 
Head, prothorax, basal half of elytra and sterna densely, minutely 
and transversely punctate-strigose, the shoulders most distinctly; 
apex of elytra and the abdominal segments minutely punctate. 
Moderately densely clothed all over with short greyish pubescence, 
somewhat sericeous on prothorax, scutellum and lower surface. 
Head rounded; antenna? slender, cylindrical, reaching about 
half way between intermediate and posterior coxae, 1st joint 
almost as long as 2nd-3rd combined, 2nd not much shorter than 
3rd, 3rd-10th very gradually decreasing, lOth-llth equal. Pro- 
thorax subquadrate, with the base — except for the slightly 
produced angles — truncate, base with a very feeble depression, 
and narrowly margined; median line distinct at base, feebly 
traceable towards apex. Scutellum transverse, feebly emarginate 
at apex. Elytra more than three times as long as wide, shoulders 
feebly rounded, sides very gradually narrowing to near the apex, 
a narrow depression on each side of the suture, a very feeble 
depression near shoulders, with feeble traces of stria?. Legs 
slender, four posterior tibiae depressed-serrate externally, spurs 
to the posterior unequal, the longest a little more than one-third 
the length of the first tarsal joint, the shortest about a fourth; 
intermediate and anterior spurs very short; posterior tarsi with 
the basal joint almost as long as the following combined, the two 
basal as long as tibiae. Length 10 J, width 2^ mm.

Several trees were riddled by this species, of which I could 
have taken hundreds; the markings are constant, but the size is 
extremely variable (I have given the extremes); the larvae are 
largely destroyed by two species of Hymenopterous parasites.
