12. Coptotermes Micliaelseni Silv. 



This species was recently described from S. W. Åustralia. 

 It is apparently a distinct species and can easily be sepa- 

 rated frora C. lacteus Frogg. by the smaller size of the sol- 

 dier, the differently shaped head, and the smaller 3rd joint 

 of the antennae, which have only 14 joints. It should be 

 observed, however, that these characters are not always com- 

 bined. Certain soldiers are more or less intermediate between 

 the two species. To the typical species belong, no doubt, some 

 winged insects, soldiers and workers, from the vicinity of Perth 

 (under Eucalyptus-bark, ^V»)- I have referred to this species 

 all small-headed soldiers with 14-jointed antennse, and with 

 the 3rd joint usually smaller than the 4th. — Localities: 

 Perth (W. Åustralia), Adelaide (S. Åustralia), Christmas Creek 

 (S. Queensland), Herberton, Cedar Creek (N. Queensland). 



13. Rhinotermes reticulatus Frogg. 



Several winged specimens taken by night at light (Ja- 

 nuary, February) at Oscars Range (Spring station), Kimberley, 

 N. W. Åustralia. 



The species has apparently a wide distribution. Taken 

 previously at Kalgooslic, W. Åustralia, and in Central 

 Åustralia. 



14. Rhinotermes intermedius Brauer. 



Winged specimens together with workers and soldiers 

 taken at Yedda (^70, Kimberley, N. W. Åustralia (under 

 rotten logs in Eucalyptus-bush) at the foot of Mt. Tambourine 

 (October, under bark of the »mahogony-tree») and at Colosseum 

 (October), S. Queensland. 



Rhinotermus soldiers and workers in large number taken 

 at Broome, Derby in N. W. Åustralia, at Yandina in S. 

 Queensland and at Cedar Creek, Evelyne and Alice River in 

 N. Queensland. To what species they belong to is impos- 

 sible to say; as no morphological differences can be found 

 between the soldiers and workers of the two very closely 

 allied species. Judging from the fact, however, that Rh.
