Body and ambulatory legs closely covered by a woolly tomentum. 
Carapace witb the regions well defined by smooth sulci, the hepatic 
regions sunken and pinched in, the surface closely and unevenly 
granular : the lateral margins are armed with knob-tipped spinules, 
of which there are sometimes as many as six, sometimes as few as two, 
on either side. 
The rostrum consists of a broad lamina which in the female is 
quite vertically, but in males is not so much deflexed, its sides are 
gently sinuous, and it ends in four sharp-cut lobes. The eyes are 
completely retractile within the orbits. 
The basal antennal joint is short and is extremely broad anteriorly, 
its greatly produced antero-external angle completing the orbit below 
and in front. The mobile portion of the antenna, which is freely 
exposed, varies in length and in the form of the flattened 2nd joint 
of the peduncle. In some males (var. mascarenica) the mobile portion 
of the antenna is half the length of the horizontal portion of the 
carapace, and the length of the 2nd joint is rather more than one-third 
the breadth of the rostrum at its own point of origin. But in all 
ovigerous females, and in certain males, the mobile portion of the 
antenna is between one-tliird and one-fourtli the length of the hori-
