Color: head grayish-brown; mandibles clear ochre yellow, with 
black teeth; palpi with the two basal segments and the proximal 
end of the femur pale; the rest of the femur and the three distal 
segments strongly infuscate ; the patella, however, rather paler and 
browner than the tibia and tarsus, which are black; legs mostly 
pale yellow, the first, however, lightly infuscate distally, and the 
fourth infuscate towards the tip of the femur; abdomen with the 
terga infuscate. 
Head flattish above, sparsely bristly, its anterior border convex, 
a deep median longitudinal furrow ; ocular tubercle furnished with 
three pairs of bristles in front and a pair behind; the eyes promi- 
nent, the space between them perhaps rather less than a diameter. 
Mandibles long, bristly above and externally ; the stridulating 
ridges seven in number; the inner surfaces of the two jaws 
bristly, the bristle nearest to the teeth being normally feathery ; 
the upper jaw armed with ten teeth, including the two which are 
situated internally at the base and are of large size; the first two 
teeth large and conical, the fourth also large, but the third much 
smaller ; those situated externally at the base of medium size; 
the lower jaw with one small tooth between the large ones and 
close to the base of the posterior. 
Rostrum horizontal, its upper edge concave, convex at the apex; 
the apex of its lower lip projecting beyond that of the upper and 
furnished with the usual pair of feathery hairs. 
Palpi with femur and patella fusiform, broader mesially than at 
the apices; the tibia regularly incrassate, narrowest at the base; 
both the patella and the tibia furnished below with two series of 
longish spines, mixed up with bristles. 
Legs unarmed except for the tibia of the second and _ third
