484 Mr. P. Cameion on 



Clypeiis with a deep fovea on either side at the base and not 

 separated from the face, its apex transverse ; hibrum pro- 

 jocting, its apex rounded. Occiput sliarply margined. Scu- 

 tellum flat, not margined ; postscutellum bifoveate at the 

 base. Median segment areolated, its spiracles linear. Areolet 

 narrowed at top, not quite one half the length of the lower 

 side ; the recurrent nervure is received in the middle ; the 

 transverse median nervure is received in front of the trans- 

 verse basal. Antennse thickened beyond the middle, the apex 

 attenuated. Legs stout, the tarsi spinose, tlie claws simple. 

 The spiracles on the petiole are placed near the base of the 

 postpetiole ; the gastrocceli large, deep ; there are seven 

 segments, the ventral keel is only on the second and third ; 

 the ovipositor is short ; the hypopygium is large, broad, 

 rounded at the apex ; the apical segment is larger than usual 

 compared to the penultimate. 



Belongs by the form of the petiole to the Platyuri. It has 

 the bluntly pointed abdomen of Ainhlyteles, with which it 

 also agrees in the apical ventral segments not being retracted. 

 Characteristic is the form of tiie mandibles, which have only 

 one very small, almost obsolete tooth on the upperside. The 

 three central arejB on the median segment are clearly detined, 

 the others are obsolete, but the keel on either side of the 

 spiracles is distinct ; the basal joints of the flagellum are 

 elongated ; the apex of the abdomen is broad and bluntly 

 pointed; the face is flat; the occiput roundly concave; the 

 two abscissae of the basal part of the cubitus are straight and 

 oblique ; a short nervule issues from the middle.

Long. 10-12 mm. 



Antennas black, a line in the middle of the scape and the 

 eighth to fourteenth joints (except above) white; they are 

 stout, flattened and dilated beyond the middle, attenuated 

 towards the apex. Head black, the inner orbits, and the 

 outer more broadly on the lower half, yellow; tiiere is a 

 broad nmrk on the lower side of the face, extending to and 

 enclosing the foveas; above it is obliquely narrowed from the 

 sides to the centre ; on the middle of the clypeus is a large 

 black mark, which is also obliquely narrowed above. Man- 

 dibles yellow, their apex narrowly black ; palpi yellow. 

 Thorax black ; a narrow curved line on the pronotum, 

 reaching from near the base to the apex, two short lines near
