Side-pieces, tenth stemites and ninth tergites as in C. occulta. Clasper with a slender, recurved, basal 'lobe' (Dyar, 1919) (i), with retrorse pointed tip, and a wide dilation («'/.), from which arise three lobes; an outer, rather slender lobe (2), with indications of a row of spines; a long curved lobe (3), with a row of teeth along inner side; an inner broad triangular.

Wyeomyia negrensis, , male hypopygium, clasper. d—dilation ; i, 2, 3, 4, and 5, lobes of clasper. lobe (4), with coarse teeth along distal edge; and a secondary lobe (5), with teeth on internal surface arising from fourth lobe. Larva. Stage IV. Head wider than long, widest at posterior angles. Mental flate triangular, with a median tooth and eleven sub-equal teeth on each side. Maxilla with a terminal transparent hook-like tooth, and a row of ten transparent teeth along inner side; a sub-apical tuft of delicate hairs, and near them a single seta on a tubercle, a row of hairs internally, and a short, stout spine near outer margin. Thorax with lateral dense tufts. Spines of comb of.
