6 . Agrees fairly closely with the description of the type. The 

 yellow mark on the dorsum of the thorax is triangular rather 

 than oval, its base ru.nning quite transversely across the thorax, 

 and its inner side close to the mid-dorsal carina. In one specimen, 

 however, the anterior margin of the triangle is distinctly oblique, 

 so that the mark becomes more nearly oval. The colouring of 

 the ventral side of the thorax seems to vary with age ; it is black 

 in the fully adult specimens, but on the younger it is yellow with 

 a smoky tinge. 



Abdomen : segments 1-7 reddish brown, 1 with yellowish mark 

 on doisum, 2-7 with black apical ring, and 2 with pale sub- 

 apical mark as well ; 8, 9 white, enamelled ; 8 with a reddish 

 tinge of rather blue-white ; 10 black. 



Abd. 30 mm. + 1 mm., h. w. 21 mm. 



2 . Head black, but with yellow median mark on post-clypeus 

 and yellow margins around the eyes. Prothorax light golden
