ERIC MJÖBERG, ISOPTERA. 65 



breadth of före wing 4,2 mm, length of liindwing 19,5 mm, 

 breadth of hind wing 4,5 mm, breadth of abdomen 2,4 mm. 

 A very characteristic and beautiful species, which in size 

 comes nearest to E, rnagnus Frogg. and E. nigerrimus Mjöb. 

 It differs from all other Australian species, of this genus 

 by baving 18-jointed antennae (in tbe species mentioned only 

 16-jointed antennse). Its broad prothorax and very long 

 wings with tbe very complicated venation give it a distin- 

 guished place among all Eittermes species of tbe Australian 

 rci^ion.

 North-West Australia in December. 



30. Eutermes sp. 



Two winged speciraens, taken swarming in tbe air after a 

 rain in tbe Kimberley district of ]S[orthwest Australia (De- 

 cember). As tbey belong to no very cbaracteristic species, I 

 bave preferred not to describe tbem as a new one, tbougb tbey 

 apparently are not identical witb any previously described Aust- 

 ralian Eutermes imago. Tbe body measures with wings 

 13 mm, tbe antennae are 16-jointed and prothorax slightly 

 emarginate at tbe hind margin. Tbe wings show tbe ordinary 

 Eutermes venation.
