XEW AND RARE AUSTRALIAN TERMITES, WITH NOTES ON THEIR BIOLOGV, 



the middle of sternites one to four, paler; wings very dark, nearly as dark as 

 sternites of abdomen, veins darker. 



Head (Figs. 20 and 21) small, round, convex on the summit, with very 

 few setae. Labrum small, slightly swollen on the sides, bluntly rounded in 

 front. Anteclypeus large, three-tenths as long a.s wide, membranous. Eyes 

 small (0.188 x 0.235), not prominent, finely faceted, lower margin distant O.isS 

 from lower margin of head. Ocelli small, oval, well separated from, and in

line with the middle of, tlie eyes. Antennae 13- (rarely 14-) jointed, the first 

 joint short and stout, 2nd half as long and three fourths as wide as 1st, 3rd 

 nearly as long as 2nd but wider at apex, 4th very little shorter than 3rd, shortest 

 of all, rounded, 5th-12th increasing in length and width, 13th shorter or abo\it 

 a*; long as 12th, broadly oval. 



Thorax: Pronotum (Fig. 22) large, wider than head, wider than long, an- 

 terior margin convex, sides rounded, postero-lateral angles nearly straight, pos- 

 terior margin markedly sinuate, clothed sparsely with short, fine, pale setae, a 

 deep depression behind the anterior margin on either side of the median line. 

 Meso- and metanotum with dark median line on anterior two-thirds, jiosterior 

 margin slightly sinuate. 



^,\'i■>\(Jn■. Wing-stumps of i'orewiugs more tliau twice as long a.s those of 

 hindwings, extending jiosleriorly to the apex of the metauntum, with a few 

 miiuite setae. Wings ( Kig. 23, PI. xxxvi.) neiu'ly equal in lengtli and widtli 

 and bearing a few minute setae along the main veins; the membrane (Fig. 24, 

 PI. xxxvi.) is without setae, but, like the veins, it is covered witli small scale- 

 like spots, densest on the veins, but present in more or less irregular lines be- 

 tween them. In the forewing the subcosta is sliort, about one-fifth the length 

 of the wing; the radius is about twice as hmg as the subcosta and bears a 

 superior branch about the middle; (he radial sector has about ten superior 

 brandies, the media is nearly parallel to the radial sector, joins the costal margin 

 at I lie apex of tlie wing, bears about 3 inferior branches towards its distal end 

 and several short, indistinct, superior branches to the radial sector; the cubitus 

 traverses the middle of the wing and bears about 12 simple or forked branches 

 to the posterior margin. In tlie liindwing the subcosta is wanting; the radius 

 bears three short, superior branches, tiie radial sector seven or eight; the media 

 branches from the radial sector well beyond the suture, not at the base of the 

 wing stump as in the forewing. 



Legs (Fig. 25) short and moderately stout. Tibial spines 3: 3:3, serrate. 



.Widtimen nearly paiallel on the sides, flattened doi-so-^'cntrally, bluntly
