flattened, forming an elongate horn-shaped piece of sugar with a 

 narrow open lace-Uke strip running down each side ; broad 

 end of lerp open, forming a flat-roofed chamber in which the 

 larva hides with its head at the opening. The leaves of infested 

 trees are literally covered with these lerp-scales, which are very 

 brittle and crack off in the sun or are washed oif by rain very 

 quickly 



Larva pale orange-yellow, legs and antennye semitransparent, 

 the latter tipped with black; eyes dark yellow. . Front of head 

 to tip of abdomen of uniform width; abdomen somewhat heart- 

 shaped. Back and outer margins fringed with fine hairs, which 

 generally carry minute globules of the white sugary secretion 

 used in constructing the lerp-scale. 



Pupa. — Head and abdomen bright green; thorax pale yellow; 

 wing covers, legs, antennae, spots between eyes, thorax, and upon 

 abdomen brown. Head large, lobed in front, constricted at base; 

 antenn[« short, stout, fringed with long hairs; eyes large, project- 

 ing. Thorax long, sloping on sides to wing-covers, the latter 

 small; legs short, stout. Abdomen large, narrow at base, broad, 

 oval to tip. 



Imago. — Length 006, antennae 0*0125 inch. 



General colour bright green tinged with yellow at base of 

 thorax, and on genitalia; antennae, eyes, and legs light brown, 

 tips of first joint of tarsi and centre of eyes black; wings hyaline, 

 nervures dark brown. Head broad, arcuate in front, rounded on 

 sides, deeply arcuate behind. Face lobes large, close together, 

 rounded at tips, clothed with fine hairs. Antennae short; 1st 

 joint very thick; 2nd broad, short; 3rd long, slender; 4th-8th 

 uniform in length; 9th-10th shorter, the latter elongated, rounded at 

 apex Eyes very large, hemispherical, projecting: central ocellus 

 small, at apex of median cleft; lateral ocelli small, close to hind 

 margin of eyes. Thorax : pro thorax produced in front into a 

 stout angular point fitting into back of head, the extremities
