ERIC MJOBERG, ISOPTERA. 31 



reticulatus Frogg. is spread more in the western and tropica] 

 parts of the continent and Rh. intermedius Brauer hithertohas 

 been recorded mostly from the eastern parts (N. South Wales, 

 Queensland), it is probable that the specimens of soldiers and 

 workers mentioned above from the Kimberley district belong 

 to Rh. reticulatus Frogg., though Rh. intermedius Brauer has 

 also been recorded once from the tropical belt (Port Darwin) 

 of Australia. 



The soldiers and workers of the species in question from 

 Kimberley were abundant at Derby. They appeared in 

 millions on the dry ground at night, making a very audible 

 noise in the dry leaves. Disturbed by light, the soldiers 

 suddenly stopped, hammering with their large head against 

 the substrate. 



In the Rhinotermes galleries (no regular nests are con- 

 strueted) live many inquilines such as staphylinids, podurids, 

 etc. among them Sinella termitum Schött n. sp. and Cypho- 

 derus pseudalbinus Schött n. sp. (see: Results of Dr. E. 

 Mjöbergs Swedish Scientific Expeditions to Australia 1910—13, 

 15, Collembola, p. 20, 50). 



15. Parrhiiioteruies queeuslaiidicus n. sp. 



The genus Parrhinotermes was established by Holmgren 

 (Termitenstudien II, 1911, p. 77—78) for two abberant mem- 

 bers of the family Rhinotermitidce, Rh. cequalis Hav. and 

 Rh. incequalis Hav., both from Sarawak in Borneo. They 

 differ from the true Rhinotermes species by having (soldier) 

 only 13-jointed antennse, differently shaped jaws and only 

 ene kind of soldiers. Three year låter Holmgren (Wissen- 

 schafl. Ergebnisse einer Forschungsreise nach Ostindien III, 

 Zool. Jahrbiicher, Bd 36, 2/3 Heft, 1914, p. 238) describes 

 a third species, called P. Buttel-reepeni, from Central Sumatra, 

 and gives at the same time the diagnosis of the imago. 



Soldier (Text Fig. 12). General colour whitish yellow, 

 jaws and labrum more deeply coloured, the former being 

 bright rufous, the latter light yellow. 



Head comparatively large, distinctly longer than broad, 

 broadest before the hind angles, parallel on the sides, rounded 

 in front, fairly flat on the summit, with scattered hairs;
