pattern moderately fine, regular; bristles on all surfaces short, rather stout, 
evenly set ; the ring joints bearing 1, 2, and 3 transverse rows respectively. 
Sensoria elongate, numerous, 2 rows (containing 22-26 sensoria) on all 
normal funicular joints and on the 1st of the club, of which the 2ud 
and 3rd bear only 1 row (16 and 7 or 8 respectively). Mouth parts. 
Labrum (fig. 19, c) oblong (8 : 5) with 4 long stiff bristles (2, 2) of which

the outer pair are as long as the sclerite itself and the inner longer. 
Maxillary palpus 3, 4, 3, 6 ; of the bristles on the galea 7-8 on the distal 
edge are stout. Mandibles (Fig. 19, b) moderately long, the lower basal 
angle a little produced, tridentate, the upper tooth broad, thin. Bristles 
nearly all on the lower outer aspect, there being about 6 moderate sized 
ones before the first tooth and a dozen minute along and about the 
ventral edge. The surfaces of the mandibles are smooth except for the 
basal ventral angle, which is curiously raised reticulate. 
Thorax. Prothorax : posterior row of bristles short 16-18 between 
the spiracles where there is an incrassation of the chitin. On the 
prosternum are 5-7 bristles posteriorly on each side of the mid line. 
Mesothorax elongate, the posterior ends of the parapsidal furrows much 
further apart (7 : 5) than the inner anterior angles of the axillae. From 
the posterior edge of the pronotum to the suture the mesonotum is as 
long as the scutellum. From above, the side lobes bulge considerably,
