markings on the elytra differently disposed. The anterior spot 

 does not reach the margin, being confined to the 4th, 5th, 6th, 

 7th and 8th interstitial spaces, the colour being shortest on 

 the 5th and longest on the three last ; the posterior spot is con- 

 fined to the same interstices, almost disappearing on the last ; it 

 is more transverse and not so much curved obliquely backwards 

 and outwards as in Symei.

Narrow and elongate ; antennae with the two basal joints fer- 

 ruginous, except a piceous patch on the upper side of the first 

 joint, the remainder black or fuscous, the fourth and following 

 joints pubescent, flattened, and wider at the middle joints than at 

 either end ; palpi piceous. Head smooth, polished, virescent, 

 lightly punctate behind. Thorax narrow, with a tendency to be 

 cylindrical, but margined, narrowed both behind and in front, 

 narrowest behind, widest about the middle ; in front very much 

 rounded-in, and anterior angles fitting close to the neck; the 

 sides gently rounded, becoming straighter a little before the 

 posterior angles, which are rounded and obtuse; very deeply 

 and closely punctate; the punctuation becomes confluent to- 

 wards the sides, and closest behind ; sparingly pilose ; margin 

 a little raised towards the posterior angles, and having within it 

 a little of a cupreous or seneous lustre; dorsal line distinct, 

 reaching neither to front nor base, deepest in front. Scutellum 

 impunctate. Elytra long and narrow, widest behind the middle, 

 opaque, black or bluish-green, the green colour most seen when 

 looked at from in front; punctate-striate, interstices punctate, 

 and bearing a double row of yellowish hairs ; with two yellow 

 spots on each, the anterior broader than long, transverse, occupy-
