ripe is oblong with rounded ends (Plate I, fig. 6x24). The colour 
darkens to a dirty brown and the segmentation of the contained larva 
is clearly visible. The mandibles, maxillae and palps show edges of 
brown chitin. 
The Larva. (Plate I, figs. 7, 8, x 18 and x 12.) 
The young larva (Plate I, fig. 7 X18) is white, oval, 1—2 mm. long, 
legless, transversely wrinkled ; dorsal surface convex, ventral surface 
flat; integument of body minutely shagreened, and bristle-bearing ; 
prothoracic segment not differentiated as in later stages. 
The older stage larva (Plate I, fig. 8 x 12) is white, cylindrical, 6—7 
mm. long, legless, transversely wrinkled with well marked head and 
12 body segments. Head white; mandibles brown edged with black ; 
maxillae light brown. Prothorax , 1st segment transversely swollen and 
stouter than the succeeding segments ; integument slightly thickened 
dorsally and bearing two transverse plates of chitin on either side of 
the median line, strengthened with 7 or 8 diagonal ridges, alternately 
bifurcate (Plate I, fig. 9). Stigmata 9, on 1st thoracic and 1st to 8th 
abdominal segments, each bordered with a plain ring of chitin. Abdomen 
with undersurface with numerous longitudinal wrinkles, crossing the 
segmental 'wrinkles, and forming isolated calli, each bearing a small 
chitinous tubercle surmounted by a short bristle. Anal segment trun¬ 
cate, with a short median tubercle and a few short bristles. 
The Pupa. (Plate I, figs. 10, 11, x 12.) 
The pupa possesses the general form and size of the adult, white, 
5—6 mm., with legs and wing pads folded beneath the body and the 
abdominal segments exposed ; 1st and 2nd pair of legs above the elytra 
on the ventral surface of the body, 3rd pair covered by the wing pads 
and elytra all except the terminal tarsal joints. Abdomen with seg¬ 
ments furnished dorsally each with a row of minute chitindus teeth.
