antennae. Head and thorax shallowly and irregularly rugoso- 

 punctate, epinotum shallowly and transversely striate, abdomen with 

 very minute piligerous punctures. Head much wider than long. 

 Eyes very large, occupying three-quarters of the sides of the head, 

 ocelli large and situated on a raised area. Clypeus flat at the sides, 

 convex in the middle, anterior margin feebly convex. Mandibles 

 small and atrophied. Scape short, twice as long as the 1st joint 

 of the flagellum, half as long as the 2nd, flagellum filiform. The 

 antennae are long, reaching back almost to the apex of the abdomen. 

 Pronotum covered by the mesonotum. The latter is very convex 

 from front to back, and as long as wide ; Mayrian furrows and 

 parapsidal sutures moderately clear. The scutellum small and not 

 much raised. Epinotum and petiole similar to that of the ? , but 

 the teeth of the epinotum less pronounced. Abdomen elongate, 

 1st segment longer than the 2nd ; pygidium sub-acute, not spined ; 

 cerci present. Legs long and slender. Wings larger than in the 

 5 and of a lighter colour. The projection of the ventral lamella is 

 triangular.

 " $ . 3 - 7-3 - 8 mm. Moderately shining, more or less reddish 

 yellow. A long erect and sparse pilosity on the abdomen ; the 

 moderately short pubescence is somewhat erect, thickest on the 

 antennae and legs, less abundant on the mandibles, head, and abdo- 

 men, scanty on the thorax. The mandibles are about half as long as 

 the head, with piligerous punctures, narrower at the base than at 

 the apex, the lower inner margin (i.e. when the mandibles are 

 directed forwards), is feebly and finely denticulate; the angle corre- 

 sponding to the anterior end of the upper and lower inner margins, is 

 strongly rounded off; the apex of the mandible ends in two medium- 

 sized teeth, directed inwards, the lower one bearing a smaller tooth 

 at its base ; the outer margin of the mandibles between the 1st 

 and 2nd fourths of its whole length, is distinctly although feebly 

 concave, beyond that the margin is slightly convex. The head is 

 shaped like that of Ghiliani, Spin., but the posterior margin is less 

 emarginate ; it is fairly abundantly punctured with rather smooth 

 shining interspaces ; from each puncture proceeds a short hair ; the 

 sides of the head behind the eyes, are very smooth, very shining and 

 sparsely punctured. The smooth triangular clypeus is wider than
