pobrachial areolet hardly longer than the prgebrachial ; recurrent 

 nervure rejected. First abdominal segment longer than all the 

 rest taken together, slender, curved, not wider behind, having the 

 spiracles just before the middle, where it is not tuberculated but 

 slightly incrassated, and again decreasing gradually from thence to 

 the apex : the other segments forming a small compressed oval. 

 Terebra subexserted.

Testaceous; eyes, stemmaticum, and valves of the terebra, 

 black; antennae infuscated towards the apex; metathorax rufc- 

 scent, becoming piceous or blackish posteriorly. Wings hyaline ; 

 stigma yellow, edged beneath with fuscous ; nervures testaceous. 

 Length, If ; wings, 3 lin. 



Distinguished from all other genera of this group by the form of 

 the abdomen, which resembles that of an AmmopTiila or Pclopccus. 

 Antennae 26-jointed, slender, as long as the body. Head rotundo- 

 cubic, wider than the thorax, and equal in bulk to the entire rneso- 

 thorax ; vertex ample, convex ; eyes prominent ; clypeus not 

 discrete, foveated on each side at the base, protruded at the apex, 

 so that a fissure appears between it and the mandibles, which are 

 bidentate. Prothorax deeply sunk between the elevated head and 

 mesothorax ; the latter trilobate, not longer than the head. Meta- 

 thorax short, rugulose, abruptly truncated behind, and there 

 triangularly excavated. ' Abdomen smooth and shining ; 2d and ocl 

 segments completely connate, concealing the rest, except the 

 extremity of the last segment. Legs long and slender. Terebra
