and obliquely striated ; vertex strongly aciculated. Pro- and 

 mesonotum smooth and shining ; the apex of scutellum obscure 

 brownish ; the pleurae opaque, strongly aciculated. Median seg- 

 ment closely, strongly striated ; the basal part of the meta- 

 notum longitudinally, the apical slope transversely striated, the 

 part behind the keel more finely than the rest and with the area 

 smooth ; the apical slope more coarsely, closely transversely ; 

 the pleune closely, longitudinally striated. All the sutur- 

 es and depressions are striated. Abdomen smooth, the 2nd 

 and 3rd segments aciculated. Metanotal spines long, fully 

 twice in length the thickness at the base ; the basal area clearly 

 defined, in length longer than the width at the base ; it becomes 

 gradually narrowed towards the apex.

 segment closely, irregularly striated, the pleurae more closely 

 and regularly than the rest ; the part of the metanotum behind 

 the keel smooth at the base, the rest closely, finely striated. 

 Metanotal spines short and thick. Abdorren smooth and shin- 

 ing ; the 5th segment is white at the apex above. Areolet square, 

 its apical nervure faint.
