1/ . 5-5"8 mm. Head varying from dark, red to piceous, thorax 

 yellowish-red, abdomen yellowish-brown, the apical halves of the 

 segments darker, legs brownish-yellow to brown. Pilosity and pube- 

 scence much the same as in Prelli, but somewhat finer and more 

 abundant on the head and mandibles. The middle of the anterior 

 half of the head longitudinally striate, with some finer striae between 

 the longer ones, the sides longitudinally rugose with a few transverse 

 anastomoses, the spaces between finely reticulate. The anterior half 

 of the head is moderately shining, the posterior half smooth, shining 

 and very sparsely and finely punctured (a few striae extend beyond 

 the middle at the sides of the occipito-frontal sulcus). Mandibles 

 smooth, shining, with some scanty and elongate punctures, the basal 

 half faintly striate. Thorax fairly shining ; pronotum transversely, 

 irregularly and finely striate, the striae stronger at the sides. Meso-

and epinotum, sides of the thorax, and the nodes finely reticulate- 

 punctate, a few feeble transverse striae superimposed. Abdomen 

 shining. 



Head a little more than one- sixth longer than wide, widest at the 

 posterior fourth, where it is about one- third wider than across the 

 anterior margin. The posterior emargination is fairly deep and wide, 

 but not acutely angular at the apex. Occipito-frontal sulcus well 

 defined in its posterior half. Sides of the head between the eyes and 

 frontal carinae not concave. The latter extend back nearly to the 

 middle of the head. Frontal area smooth, shining and depressed. 

 Eyes placed at the anterior third of the sides. Clypeus fairly strongly 

 carinate in the middle, the anterior margin feebly concave. Posterior 

 lateral angles of the pronotum subacute, projecting very slightly 

 outwards, much more pronounced than in Prelli-redbanJeensis. The
