large, rounded in front, with a dark spot on either side; labrum 

 rather long, narrow and truncate in front and straight on the 

 sides : anal appendices large, at right angles to each other; cerei 

 as in others; body long and cylindrical. 



Hah. — Mackay, Queensland. (Mr. G. Turner). 



Calotermes improbus, Hagen. 



Hagen, Mon. Linnit'a, xii. p. -il. 



Chestnut brown, head somewhat darker; antennte, legs, and 

 underside bright yellow; head and thorax smooth, not hairy. 

 Length 6i mm. 



Head oblong, quadrangular, almost half as long again as broad, 

 rounded posteriorly. Eyes small, projecting slightly, well in 

 front of head; ocelli large, away from the eyes, a small central mark 

 or false ocellus almost in a line with the hind margin of the eyes. 

 AntennjB short and stout, longer than the head, 20-jointed, 

 coalesced, round; first joint larger than the following ones, 4tli 

 and last smallest. Labrum short, oblique below the jaws; labial 

 palpi thicker and shorter than in the other species. Pi'othorax 

 large, broader than the head, rounded and flat, sides turned down 

 in front, concave, rounded posteriorly, the angles rather truncate 

 behind. Scapular shield of forewings large, I'ound and truncate) 

 longer than the mesothorax. Wings wanting. Legs short, with 

 three spines at apex of tibire; the only existing claw is short, 

 sharp, and curved; if a j)lantula is present it is not noticeable in 

 this specimen. Body egg-shaped, broad; abdominal appendices 

 very small, two small cerci. 



The above description is taken from Hagen's Monograph. He 

 described this species from one imperfect specimen, without wings, 

 and with only one imperfect leg. 



Hah. — Tasmania. It does not agree with any of my species 

 from Australia. But in the case of a species known only from a 

 single imperfect individual it would l^e haixl to identify it without 

 a good series of specimens collected in the same locality.
