markings in the middle of the mesonotum and scutellum black or 

 very dark purple ; antenna} and tarsi dull black, the scape in front 

 and the basal two segments of the flagellum above dark blue ; head 

 and thorax coarsely and very closely punctured, cribrate ; abdomen 

 very finely, somewhat densely punctured, the 1st segment with 

 scattered large punctures at base ; the punctures on the head and 

 thorax with minute punctures within, those on the abdomen, 

 especially on the apical two segments, shallow ; pilosity short, 

 brownish, only moderately abundant, sparse on the 2nd abdominal 

 segment, no whitish pubescence in the facial hollow in the three 

 specimens I have seen. Head as broad as the pronotum ; clypeus 

 broad, its anterior margin transverse ; facial hollow shallow, 

 margined above, coriaceous within, slightly above it on the front is 

 a sinuate transverse carina, no distinct carinse emitted from it 

 towards the vertex ; antennae long, cylindrical, pubescent ; the 2nd 

 joint of the flagellum twice the length of the 1st ; vertex and front 

 c-onvexly sloping anteriorly ; occiput transverse. Thorax : the 

 prouotum convex, transversely rectangular, the sides with a sinuate 

 margin ; propleurae excavate ; mesonotum and scutellum convex, 

 the latter slightly but suddenly narrowed from near the base to 

 the apex, its posterior margin transverse ; median area of meso- 

 notum rectangular, its anterior lateral angles Jiot outwardly 

 curved or broadened ; mesopleurae coarsely rugose, the triangular 

 apex excavate and margined by a carina : postscutellum semi- 

 circular, not produced or overhanging the median segment ; the 

 latter vertical, with a series of large depressions arranged in V- 

 shape on its posterior face, the lateral angles produced, acute, some- 

 what thick ; wings hyaline, with a slight fuscous tint anteriorly ; 

 nervures brown, tegulse purple ; legs somewhat robust. Abdomen : 

 the 1st segment anteriorly very slightly concave, a short, broad, 

 medial longitudinal impression at base above ; 2nd and 3rd seg- 

 ments medially carinate, the latter comparatively long, with the 

 middle portion raised in a transverse line in front of the anteapical 

 series of foveae, these very large, well-marked and open ; the 

 apical margin with teeth, of which the 4 medial are long, narrow 

 and acute, closer to one another than to the outer, somewhat short 

 and obtuse teeth on each side of them. 



d". Two specimens from the Haungdraw valley, Tenasserim, 

 which 1 identify as the males of this species, are identical in 

 structure and sculpture with the $ , but are entirely green in colour, 

 with black markings similar to those on the $ .
