margin of the epinotum. The inner spines of the petiole are barely 

 divergent, directed vertically upwards, about one-third longer than 

 the outer spines and a little nearer to the latter than they are to each 

 other. The outer spines twice as long as their basal width. 



9, 7-9 mm. Pronotum merely angular on each side, not dentate. 

 Dorsum of epinotum also only angular at the posterior corners. The 

 outer spines of the scale are a good deal thicker and more obtuse than 

 the inner ones, and only a little shorter. Wings tinged with brown, 

 nervures ochreous brown, stigma brown. Otherwise like the g.

$, 4*8-5-5 mm. Black. Head and thorax dull, abdomen fairly 

 shining. Head sharply and longitudinally striato-rugose, thorax 

 and petiole more or less longitudinally rugoso-reticulate. Pubescence 

 greyish, long, decumbent, fairly abundant all over, particularly on 

 the thorax. Pilosity greyish yellow, erect, long and abundant all 

 over. Head longer than wide, subovate, wider behind than in front. 

 Clypeus subcarinate, the anterior margin arcuate. Eyes placed at 

 the posterior third, fairly convex and prominent. Pronotum with a 

 tooth on each side which is broad at the base and thin in its apical 

 half, as long as its basal width. Pronotum two and a half times wider 

 than long, and quite twice as wide between the teeth as the apical 

 margin of the epinotum. Both thoracic sutures feeble. Mesonotum 

 two and a quarter times as wide as long. Dorsum of the epinotum 

 trapezoidal, two-thirds wider in front than behind, sloping steeply 

 downwards, armed on each side behind with a very small and vertical 

 tooth. The inner spines of the scale vertical, curved slightly back- 

 wards, much longer than their basal width, about two-thirds as long 

 as the interval between their bases ; the outer spines very short, 

 merely triangular teeth, placed close to the inner spines.

 or sometimes furnished with a small and obtuse tooth. The
