Remarkable among the whole of the Halticidie for its peculiarly 
shaped head and its enormous antenns, which exceed in length 
twice the length of the body ; the head is vertical, with a somewhat 
produced and compressed labrum, the crown is prominent, and (when 
viewed sideways) is produced forward so as to form a ridge between 
the eyes, at the apex of which are placed the antenne. There is in 
the shape of the head a singular identity of form between the Fiji 
insect, which is the exponent of the genus before us, and the South- 
American form Lowoprosopus: in each the antennee are marvellously 
developed, and we may suppose that by reason of these heavy, jointed 
antennee the front of the head, from which they take their rise, should . 
have special strength, and probably on this account assumes a par- 
ticular and abnormal form: at all events in each of these genera, both 
manifestly approaching the Longicornia in the length of the antenne, 
1s found the peculiar-shaped head which is the common type of the 
head of the Longicornia. 
This, however, is the only special feature that is common to Lowo- 
prosopus and Febra; the globular inflation of the posterior claw 
of the former places it in quite another subsection of this enormous 
group. In the genus before us the antenne are as remarkable for 
their size as the body of the species before me is for its beauty. The 
first joint is longer than the breadth of the head, is slightly curved 
and, towards the apex, thickened; the second is very minute; the 
third is decidedly longer than the fourth, which in length is equal 
to the first; the apical joint (see magnified outline of it, Pl. XII. 
fig. 5g) is curiously angulated near the tip. In the feet the under- 
sides of the joints of the tarsi are thickly clothed with a dense pale 
pubescence ; the claws, at their inner margin near their base, are not 
simply appendiculated, but have a small, sharp, distinct spur. 
The type of the genus is found in the Fiji Islands.
