ENDEIS PELLUCIDA. 91 



The proportions of the antennal joints as given

Endeis formioina, Bucldon. Plate CXXIX,figs. 1 and 3. 

 Viviparous female. 



Inch. Millimetres. 



Size of body 0-045x0-040 M4xl'01 



Length of antennas 0*01 5 0*38. 



Opaque white, globose, smooth, somewhat mealy;

 joints. Legs and antennas brown. Rostrum short

 slopes. 



Endeis pellucida, Bucldon. Plate OXXIX, figs. 2 and 4. 

 Viviparous female.
