reticulate as in the type-species. The sides of the head are also more 

 regularly striate and with fewer transverse bars, and the fundamental 

 reticulation in that region is also much stronger. The occipito -frontal 

 sulcus is deeper, the posterior emargination is deeper and more angular, 

 the apex of the emargination being an acute angle. The posterior 

 lateral angles of the pronotum are more pronounced, and the scutellar 

 portion of the mesonotum is usually oblique and lacks the horizontal 

 ledge present in the type. The lateral angles of the 2nd node are 

 narrower and project further outwards owing to the greater width of 

 the node, which is quite twice as wide as long. Otherwise like the 

 type- species. 



^ . Colour a little darker than in the type-species. The dorsum 

 of the epinotum is very shallowly but fairly distinctly excavated 

 longitudinally, i. e. concave transversely (flat or even a little convex 

 in the type- species). The epinotal spines are less vertical. Otherwise 

 like the type-species. 



2. 6'8 mm. Colour like that of the 1/, base of the abdomen 

 reddish-brown. Head longitudinally striate in the middle between 

 the frontal carinae, the sides of the head longitudinally rugose, with 

 some transverse bars in addition. Back of the head, behind the level 

 of the posterior ocelli, truncate and flattened, subvertical. The larger 

 striae and rugae end at the brow of this truncation, which is only 

 finely and obliquely striate and sparsely punctured. Mesonotum and 

 scutellum smooth, shining, very sparsely and feebly punctured ; the 

 lateral margins in front of the tegulae, and two longitudinal bands 

 internal to the parapsidal sutures, are rugulose or reticulate ; the 

 margins of the scutellum coriaceous. Metanotum, epinotum and 

 petiole dull and transversely striate, closely and finely so on the nodes, 

 the spaces between the striae coriaceous. Abdomen shining except the 

 base, which is finely striate-reticulate and dull. 



Head, excluding the mandibles, a little wider than long, wider 

 behind than in front, the posterior margin straight, the posterior 

 angles narrowly rounded. Mesonotum a little wider than long, rounded 

 in front, flattened behind above ; scutellum twice as wide as long. 

 Dorsum of epinotum subvertical, concave transversely, not clearly 

 delimited from the declivit} r . Epinotal teeth nearly horizontal, acute, 

 parallel, not longer than their basal width, somewhat incurved towards 

 their apices. Posterior-dorsal face of the 1st node wider than in the 

 1/ , the dorsal edge shallowly emarginate in the middle. Lateral angles 

 of the 2nd node more acute than in the "2/ . Dealated. 



$ . 5 mm. Mandibles, clypeus and the space between the frontal 

 carinae and anterior ocellus brownish-yellow, the rest of the head
