uarrowed posteriorly. In the cleft of the second and third segments lies 

 the first segment, composed of two very narrow, long plates, of which the 

 inner margins are close together, covering the ovipositor throughout its 

 length, reaching from its base to the end of the third segment, where they 

 are more visible than between the margins of the cleft of the second 

 segment. The long, strong, ovipositor, when at rest, is entirely shut in 

 and concealed t)y the plates of the first segment, whence it is protruded 

 for the fulfilment of its functions. Div. 1, UnicelluU. — Membrane with 

 one cell. Div. 2, Bicelluli. — Membrane with two cells.
