 scapes reacli the occipital border or a fraction t'artlier. Eyes 

 prominent, slightly in front of" the centre of sides. Pro-

 the centre of each side is a tooth-like ridge. Basal surface of 

 epinotnin longer than declivous surface ; spines much shorter 

 than basal surface, about as long as the interval between 

 them. First node narrow, straight across the top; seconil 

 node oval, longer than broad. 



Head coarsely striate longitudinally and finely reticulate. 

 Thorax and pedicel finely reticulate ; pronotum witli a few

 to the epinotum. Front of first segment of gaster faintly 

 reticulate.

Clypeus emarginate in front, with a lidgc down the centre. 

 The ridges continuing the frontal carinie are two-thirds as 

 long as the scaj)es, which reach beyond the half distance 

 from their bases to the occiput. Eyes just within the 

 anterior third of sides of head. The impression from the 

 occij)ital emargination is continued to the vertex. Spines 

 as long as the basal surface of ei)inotum and longer than the 

 interval between them. 



Whole of upper and under surfaces of head finely reticulate ; 

 in addition, the under surface of front of head, the cheeks, 

 and the whole of the top of head longitudinally striate ; the 

 ridges on each side of the central impression curve round the 

 lobes of the occiput and continue down the sides of the head, 

 those farther fiom the central impression making a narrow
