features of coloration, it would appear that a certain amount of 

 differentiation in Giglio-Tos' material is clearly ascribable to indi- 

 vidual variation. The present specimens all have the internal spines 

 of the cephalic tibiae black at their apices. We therefore do not 

 feel justified in recognizing borneana either as a valid species or 

 race.

The present specimens measure as follows: length of pronotum 

 cf 8.8 to 9, 9 13.9; width of pronotum cf 6 to 6.4, 9 9; length of 

 tegmen cf iO.8 to 41, 9 53 mm. 



The two males at hand, though from very widely separated 

 localities, are extremely similar, that from Jelabu slightly the paler 

 in general coloration and very slightly the larger.

The present species, one of the smallest of the described forms 

 of the Mantidse, is now known to have a wide distribution on the 

 Australian Continent. The present specimen measures as follows:

 length of tegmen 9.8, width of tegmen 2.7 mm.
