brum, nearly filiform, geniculated, rather stout and hairy, more 
pubescent towards the apex; 11 -jointed, basal joint long and 
clavate, 2nd and 3rd a little elongated, of equal length, the re- 
mainder moniliform, 4th joint the smallest, subovate, 5th more 
orbicular, the following a little transverse cup-shaped or ob-

Labrum transverse, rounded and bilobed, being deeply cleft in 
the middle, the lobes horny at the base, fringed with long 
bristles, the margin broad and thin, densely pubescent towards

Mandibles very similar, elongated, a little curved, the apex form- 
ing a long claw, dilated a little internally at the middle, and 
forming a small tooth above in one (2), and a tubercle only in 
the other, emarginate beneath, with a membranous margin and 
a series of hairy filaments, forming an orbicular compressed 
brush of hairs (2). 
Maxilla rather small, terminated by a small oval lobe densely 
pubescent, and a long one on the inside, thickly ciliated. Palpi 
nearly of equal length, but these are a little the stoutest and 
4-jointed, basal joint not very short, subclavate, 2nd the long-

a long narrow curved lobe on each side before. Palpi arising 
from 2 scapes towards the apex of the lip, elongated, slender
