Wings long, hyaline, elytra with a narrow fore-marginal opaqne area, diminishing 

 towards apex, and with two black spots, not very well defined. Anterior legs 

 shorter and finer than in female. Length of body, 98 mm., of pronotum, 35 mm., 

 of elytra, 56 mm. Cairns (A. M. Lea, Type male, I. 14068). 



Ilab. Qneensland. 



We have a pair of this species from Cairns. The female agrees with Wood- 

 Mason 's fignre, except that the spines of pronotnm are less densely set and some- 

 what more blunted in appearance. The apical joint of the cerci is broad and 

 twice as long as wide.

S Smaller than female, brown. Antennae very long. Pronotnm as in 

 female, but slightly less dilated, margins strongly serrated. Wings long, hyaline, 

 the fore-margin of elytra reticulated black, and with black spots as in the other 

 sex. Legs concolorons. Length of body, 93 mm., of pronotum, 32 mm., elytra, 

 54 mm. Roper River (H. E. Warren). Type, male, I. 14069. 



Hah. Northern Territory: Victoria River (type), Darwin, Stapleton, Roper 

 River, Groote Eylandt, North-west Australia. 



The first female from Groote Eylandt (fig. 29) has the pronotum shaped as 

 in the figure of the type. The other specimen (from Roper River) has the 

 pronotum very strongly dilated, and this seems to be the more usual form in the 

 Northern Territory. Sjostedt's figure of a "male" larva agrees with other larvae 

 of this species in our big series.
