" ^ • 3*9-5 mm. Mandibles strongly striated, the masticatory 

 margin moderately oblique, short. Anterior margin of clypeus straight 

 and entire. Frontal area distinct. Head more or less quadrate, slightly 

 wider than long, distinctly wider behind than in front, feebly emarginate 

 behind, rounded behind the eyes. The latter fairly large, placed in 

 the middle of the sides, of which they occupy nearly one-quarter. 

 The scapes extend back as far as the occipital margin. Antennae 

 11- jointed, all the joints of the flagellum longer than wide, but the 

 3rd-5th joints are almost as wide as long. Club 3-jointed. Dorsum 

 of pronotum convex and marginate. Pro-mesonotal suture distinct. 

 Dorsum of mesonotum longer than wide, wider in front than behind, 

 slightly convex, marginate at the sides, without a median carina or 

 t.ubercle. Meso-epinotal suture fairly strong. Dorsum of epinotum 

 fairly convex, widened posteriorly, wider than long, ending in two 

 robust spines, short, feebly pointed, subhorizontal, feebly divergent 

 and slightly curved inwards ; their external margins continuous with 

 those of the dorsum ; they are a little longer than their basal width. 

 Declivity oblique, as long as the dorsum of the epinotum. First node 

 as in 0. scutellaris, 01., widened in front, the anterior margin straight, 

 the anterior angles rounded, without a tooth below. Second node 

 divided into two subcircular halves by a deep groove ; it is a little less 

 wide than the 1st node. Abdomen fairly elongate. Finely but quite 

 distinctly reticulate, not very shining. Thorax and petiole subopaque. 

 Clypeus and cheeks finely and closely striated longitudinally. Pronotum 

 finely rugose transversely. Legs and scapes reticulate ; declivity of 

 the epinotum smooth. There is a sparse and much oblitei*ated punc- 

 turation, somewhat more distinct on the abdomen. Pilosity absent, 

 except a few hairs on the front of the head and the under-side of the 

 abdomen. There is a yellowish, adjacent, short and evenly spaced 

 pubescence on the whole body and on the limbs. Castaneous brown, 

 including the legs. Thorax and petiole of a rather paler brown. 

 Abdomen yellowish rusty-red, mandibles and front of the head of a 

 more reddish-brown.
