and oblique at the apex. Clypeus separated from the 

 face only at the sides, not behind, its apex obliquely 

 depressed ; at the sides bounded by a sharp oblique keel, 

 which projects slightly on to the labrum, which is large 

 and rounded at the apex. Mandibles unequall)' bidentate 

 at the ape.x. The second joint of the maxillary palpi 

 dilated gradual)}- towards the apex. Mesonotum trilobate, 

 the middle lobe not greatly raised, flat. Scutellum large, 

 flat. Median segment with only one transverse keel; 

 the spiracles linear, rounded at the base and apex ; the 

 teeth are large; legs long, especially the hinder, the tarsi 

 spinose, the fourth joint armed with six long spines on 

 either side beneath ; the claws long, simple. Areolet 

 large, broader than long, the recurrent nervure is received 

 very shortly beyond the middle ; the transverse median 

 nervure in the costal cellule distinctly before the trans- 

 verse basal. Petiole slender, gradually, but not much, 

 widened towards the apex ; the spiracles are received 

 shortly be}'ond the middle. Gastrocculi <mal!. 



Belongs to the Cryptides and comes near to Cerato- 

 cryptus, but it wants the frontal tubercles. Ceratoayptus 

 wants the facial tubercle and the keels on the sides of the 

 clypeus, while its areolet is small as in Mesosteims : in the 

 present genus large as in Cryptus.
