insect agree, however, especially the characters of the reddish- 
brown thorax, apical abdominal banding, and the base of the 
first sub-marginal cell being nearer the apex of the wing than 
that of the second posterior cell. It is strange, however, that 
Van der Wulp did not mention the white scaled venter, unless 
it were denuded, when it would be dusky in hue. The dark 
lateral spots on the venter are very distinct, and should serve at 
once, with the apically banded abdomen, to separate it from all 
other Stegomyias.

“ Evidently very similar to C. fasciatus , Fabr., but differs in having 
untoothed ungues in the ?, and, according to Coquillett, by the silvery 
lateral stripes not being so curved, and it has the tarsal joints banded at 
both ends.” 
Genus 10.— ARMIGERES. nov. gen. 
Head clothed with fiat scales and a few upright forked ones ; 
thorax with narrow curved and long almost hair-like scales; 
scutellum with flat scales only. The wings have the third long- 
vein continued on, into, and through the basal cell as a distinct 
unsealed line, and the sub-costal and first long veindensely scaled 
with rather broad scales. Fore and mid ungues of the female 
equal and toothed, hind equal and untoothed ; in the male those 
of the fore feet are very unequal, both toothed; in the mid legs 
both ungues smaller, very nearly equal, both toothed ; hind equal 
(and simple V). Comparatively large species with unbanded legs 
and abdomen, but the latter with lateral spots. Palpi of the £ 
thin with no hair tufts, of the 9 rather longer than in Stegomyia. 
Antennae in the $ large densely plumed, more than half the 
length of the proboscis. This genus differs from Stegomyia in 
general appearance, being longer, with unbanded tarsi and 
abdomen, and the palpi are very pointed and provided with 
bristles only, and no hair tufts in the £ . The larvae are very 
peculiar (vide p. 326).
