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 Hghts appearing wholly ferruginous, in others only their 

 apices, basal joints of antenn^ie, 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; antennae slender, cylindrical, reaching about 

 half way between intermediate and posterior coxie, 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 tibi?e 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 a1)out 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 J mm. 



^. Differs in being smaller and narrower. Length 3, width 

 4 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.
