The mandibles of this species are very sickle-shaped (fig. 5 4), with two strong teeth on the inner edge, of 
which the second is truncated. The maxille (fig. 5c) are terminated by a long narrow membranous blade, 
which unite and form a tubular defence for the labium. The maxillary palpi are long, slender, 4-jointed, the 
last joint slightly clavate. The mentum (fig. 57) is slender and tubular, as is the labium, the labial palpi 
2-jointed, the second joint slightly clavate. The front of the thorax is vertical and concave, forming a saucer- 
shaped space for the reception of the head. Fig. 5 ¢ represents the insect seen sideways, with the limbs removed.

The obliteration of the parasides and scutellum, and the simple third joint of the antenne, together with 
the peculiar armature of the postscutellum, distinguish this insect from all the other species of the sub-family.
