276 A NEW AUSTRALIAN TEB3IITE, 



about 8 setae near the apex. Clypeus large, straight in front and on the sides^ 

 Antennae (Text-fig. 2) 14- jointed, first short and broad, the proximal half 

 obscured by projecting dorsal margin of antermal foveola, second much narrower 

 and shorter, these two without setae, third very lai-ge, strongly chitinised, narrow 

 at the base, swollen towards the apex, setaceous like remaining joints, fourth 

 very small, rather larger than fifth, fifth and following joints moniliform. Gula 

 long, much narrowed in the middle, where it is one-fifth the width of the head. 



Thorax: Pronotum a little wider than bead, markedly arched, almost semi- 

 circular in transverse section, anterior border deeply concave, antero-lateral angles, 

 rounded and projecting well over posterior-lateral area of the head, sides reced- 

 ing to the broadly rounded posterior margin, the latter slightly arcuate in the 

 middle. Meso- and metanotum a little narrower than pronotum, with sides and 

 posterior margins less rounded. No evidence of wing-pads. 



Legs (Text-figs. 3 and 4) short and stout, femora greatly thickened, with 

 few setae; tibial spurs 3:3:3, short, stout, serrate. 



Abdomen short, a little longer than thorax, tapered to the apex. Cerci 

 present. 

 Measurements : 



Total length, 11.00 mm. 



Head and mandibles, long 5.00. 



Abdomen and thorax, long 6.00. 



Head : from base to labral suture, long 3.29 ; wide 1.92 ; deep 1.64. 



Mandibles, from apex to external articulation, long 1.88. 



Pronotum: long* 1.36; wide 2.06. 



Tibia iii. long 1.27.

Colour : Head mars yellow with dark russet area at articulation of mandibles ;, 

 antennae, leg's and thorax antimony yellow. 



Head clothed with a few, short, pale setae, nearly circular, widest .midway 

 between the base of elypeus and posterior margin, the antero-lateral areas sloping 

 abruptly from the posterior margin of the antennal fossae to the ai-tieulation of 

 the mandibles, flat on the summit. Clypeus as in soldier; labrum short, strongly 

 convex, rounded in front, bearing a few short pale-coloured setae. Antennae 17- 

 jointed, first joint short and broad, second about half as long but nearly as wide, 

 slightly narrowed at the base, third nearly as long as second and a little wider 

 at the apex, nearly quadrate, fourth nearly as wide as third but only half as 

 long, nearly rectangular, fifth a little longer and wider than fourth, widest in the 

 middle, sixth as long and wide as fifth but more rounded, seventh to seventeenth 

 moniliform. 



Pronotum as in soldier, with very few setae; wing-pads short and thick, 

 projecting but little. 



Legs short and stout, with scanty setae, femora thickened, tibial spurs 3:3:3, 

 serrate. 



Abdomen moderately short and broad, with few setae; cerci very short and 

 stout at the base; styli rather stout, broad at the base. 

 Measurements : 



Head: from base to labral suture, long 1.83 mm.; wide 1.50. 



*In this, as in all earlier papers, I have given the maximum pronotum length, 

 not the length along the median line (Light, 1921, p. 29). The difference is con- 

 siderable in species with deeply notched pronotum. In all other respects my 

 measurements correspond with those defined by the above author.
