TERMITES FROM THE AUSTRALIAN REGION. 
short, anterior margin sligiitly produced in the middle. Lahrum 
short and wide, widest across the middle, broadly rounded in front, 
with scattered moderately long setae. Palpi very dark, apex of 
terminal joint pale. Eyes small (O’ 187 diameter), circular, pro- 
minent, finely facetted, separated from the lower margin of the head 
by a space equal to half their diameter. Ocelli small, broadly oval, 
well separated from the eyes. Antennae (Fig. 66) 14-jointed ; the 
1st joint short, one-fifth longer than wide ; 2nd half as long as 1st. 
a little longer than wide ; 3rd very short and narrow ; 4th to 13th 
increasing in size progressively ; 14th longer than 13th, about as 
long as 1st. Fontanelle represented by a linear ])rominence. 
Thorax (Fig. 65). — Pronotum, narrower than head, anterior 
margin nearly straight and slightly bent up anterolateral angles 
rounded, sides slo])ing to the slightly emarginate posterior border. 
Posterior margin of mesonotum markedly sinuate ; that of meta- 
notum very irregular, geHerally approximating the form shown in 
figure. 
Wings.- Wing-stumps rather densely clothed with long pale 
hairs. Wings (Figs. 181, 182) light fuscous, with the two anterior 
veins and the first 5 or 6 branches of the cubitus dark, margin 
moderately densely ciliate except on the basal one-third of the hind 
margin. JMedian vein passing through the wing slightly above the 
middle, indistinct except at the base, with three or four branches to 
the posterior border. Cubitus with seven or eight branches, two or 
three of which are generally branched. Wing-membrane wdth 
minute micrasters and numerous small setae ; the latter apparently 
wanting, or almost wmnting, on hindwdngs. 
Legs . — Short and rather slender, moderately setaceous. 
Abdomen.- Long, narrowed at the base, nearly parallel on the 
sides from the 3rd to 6th segments, broadly rounded at the apex. 
Tergites and sternites markedly setaceous. C'erci small.
