Orbits not very divergent ventrally, a transverse line through the anterior 
ocellus being to the base line of the eyes in ratio 5 : 6. Malar space deep, 
in ])rofile two-thirds of the eye, which the keel itself just equals. Clypeus 
narrowed, with a median notch and one at each angle where it meets the 
gense. Antennae set on the base line of the eyes, about one-third of 
the scrobes being below, the latter oval, inclining towards one another 
and hardly narrowed superiorly. Bristles on the face rather sparsely 
set, those at the orbits not more developed, 8-9 short bristles between 
the scrobes, one above each lateral notch longer. 
Antenna : length, -75 ; scape (19 : 5) not quite as long as the sum of 
the normal funicular joints and less than three times as long as the pedicee 
(19 : 7) pedicel (8 : 5) ring-joint compound, a large basal joint with stout 
stalk and a second consisting of at least two laminae ; funicle with joints 
in ratio 7:7:6, breadth in same scale, 5, the second and third a little 
broader ; the club joints are 5:5:4 with a breadth of 7-8. The sensoria 
are numerous each joint of funicle and club bearing two rows, as follows 
10 : 12 : 14 ; club 16 : 14 : 6. The sensoria of the posterior rows are

short with long narrow processes, while those more distally situated are 
longer with short broad flanges. 
Mouth parts : labrum trapezoidal, broadest anteriorly, with fou^ 
long stouti.sh bristles, two more central and two at the sides, each of the 
latter pair extending to twice the breadth of the sclerite itself. Mandi- 
bles (Fig. 21) broad, basal edge only about one-eight less than the length 
lowermost tooth short, the uppermost large and separated by a shallow
