. Fig. 9. Antenna of N. quadrifascata. From the inside the third joint also short, truncately triangular with a somewhat reni- form base; it is somewhat compressed, bearing a dorsal, two-jointed arista, with a short basal joint; the first antennal joint has no hairs above, the second joint has a circlet of small bristles at the apex, longest above, the third joint is distinctly hairy, and the arista has short hairs. Epistoma narrow, a little broader in the female, some- times widening a little downwards; when the eyes are contiguous below the antennæ the epistoma is only present above and belo
