Several of the species of the genus (e. g., N. Kirbit, 
NN. Sykesiana) are remarkable for having the antennz 
terminating in a dilated knob-like joint, giving them the 
appearance of the antenne of a butterfly. Another 
species, presenting the same peculiarity, differs from the 
other species in the dilated tongue, and comparatively 
slender and simple hind legs. These characters seem 
sufficient to warrant its separation as a distinct genus, to 
which I have applied the name of Monta as an anagram 
of that of Nomia. Another insect, with similar antennz, 
from Java, has just been described by Mr. Ritsema in the 
Transactions of the Dutch Entomological Society, but 
having only two submarginal cells in the forewings, the 
ordinary 2nd and 3rd cells being thrown together; as 
however an irregularity in the discoidal cells of the fore- 
wings appears to exist, as shown in the two sides of the 
figure of the insect (plate 10, fig. 4), it is possible that the 
specimen represented may have been a monstrous Nomia, 
having irregularly developed veins. A fourth genus, with 
knobbed antenne, is described by Mr. Smith (supra, p.47).

This large species is distinguished by its very short and 
thick hind femora and tibiz, and the elongated joint of 
the hind tarsi, thickened at the base, and gradually be- 
coming thinner to the tip. The general surface of the 
body is obscure, except the narrow posterior margins of 
the abdominal segments; the face is clothed with whitish
