 with a wide, longer than wide area of equal width in the centre ; 

 the sides finely , closely rugose , with 2 keels (finer than the

Kuching, Borneo (John Hewitt). 



Face closely , rugosely punctured , more or less striated 

 above ; the clypeus clearly separated from it, more shining, finely, 

 closely punctured, its sides bordered by wide furrows ; the outer 

 orbits obliquely striated, finely and closely above , more strongly 

 and widely below, this being also the case with the malar space, 

 Avhich is two-thirds of the length of the eyes. Upper inner orbits 

 broadly , closely reticulated ; the centre of the front and vertex 

 shining, almost smooth ; a stout keel runs down from the ocelli. 

 Apex of mandibles piceous ; palpi dark testaceous. Middle of 

 mesonotum raised, finely, closely rugose, the sides more coarsely, 

 rugose and irregularly reticulated ; on the outer edge are 4 foveae. 

 Scutellum finely rugose and irregularly striated , gradually nar- 

 rowed to a bluntly rounded point at the apex ; at its base are 

 3 deep , longer than wide , foveae , of which the central is of 

 equal width, the lateral narrowed towards the apex, the 2 keels 

 dividing the foveae are distinct ; the basal half of the space 

 bordering the scutellum is stoutly striated, the apical very smooth 

 and shining. Metanotum coarsely reticulated , the apex trans- 

 verse above , the central basal area is roundly narrowed above, 

 below it are two small square ones, followed by 2 larger Square 

 areae. Basal half of propleurae rugosely , irregularly punctured, 

 the apical somewhat coarsely longitudinally striated. Mesopleurae 

 finely, closely rugose above, the rest reticulated , the lower reti- 

 culations longer than the upper ; the metapleurae more strongly 

 reticulated , the reticulations round. Abdomen longitudinally
