 tennsB slender, orange-coloured tipped with black.

Body rather larger and more oval than that of the 

 apterous female. Head small. Thorax very large. 

 Abdomen oval. Colour much like the preceding insect, 

 dullish brown with darker thoracic lobes. • Nectaries 

 small and conical, rising from black patches. Cauda 

 obtuse. Anterior and medial pairs of legs moderately 

 long, but posterior pair disproportionately so. Colour 

 same as with the apterous female. Antennae orange- 

 yellow, tipped with black ; pilose. Wings relatively 

 short, rounded at the tips ; insertions yellowish ; 

 cubitus and stigmata brown. The first furcal and the 

 cubital veins take their origin 'from the same point, 

 and do not anastomose from the cubitus. Membrane 

 hyaline, and handsomely brocaded with rich brown, 

 the colour being caused by a dense net-work of faintly 

 pigmented hexagonal cells like those of a honey-comb. 

 The whole of the first discoidal and the first cubital 

 cells are thus covered ; and also parts of the second 

 discoidal, the second cubital, and the marginal cells. 

 A brown blotch on the stigma is carried into part of 

 the infra-marginal cell. The margin of the wing has 

 several ornamental indentures of the uncoloured mem-
