June is, i92i Anastatus semiflavidus 
ally, the larva appears crescent-shaped and is slightly depressed dorso- 
ventrally. The head is partly retracted and not chitinized. The man¬ 
dibles are small and almost invisible. 
The body segments, 13 in number, are 
well defined and slightly broader dor- 
sally than ventrally. This causes a well- 
defined fold just above the pleural areas 
which becomes more pronounced pos¬ 
teriorly. A narrow ridge extends down 
the median line dorsally. The head and 
first two body segments are .sparsely 
pubescent. 
The average dimensions of the larva are: Length when extended, 2.5 
mm.; width, 1.25 mm.; depth dorso-ventrally, 1 mm. 
pupa 
The pupa (fig. 2) when first formed is creamy white in color and closely 
resembles the adult in shape. The appendages are 
folded close to the body, and the entire pupa is covered 
by a thin pupal skin. The sex differences are early 
apparent. The female pupa, when extended, averages 
2.5 mm. in length, and the male pupa, 1.75 mm. Soon 
after formation, the eyes of both sexes turn pink and 
gradually the thorax and abdominal bands of the 
female become light brown in color, while in the male 
they become dark blue-green. Just before the emer¬ 
gence of the adult, the entire pupa assumes the char¬ 
acteristic color of its sex.

All attempts to dissect the egg of Anastatus semifta - 
vidus from its host or t0 ascertain the length of the incubation period have 
been unsuccessful. 
The period of normal oviposition in the field begins when tire Hcmi- 
leuca oliviae eggs are first deposited, about the middle of September, 
and continues until the arrival of severe winter weather, which occurs in 
these comparatively high altitudes during late November or early 
December. 
Judging from indications furnished by numerous dissections of host 
cggsfroinlife-lnstoty cages and from eggs collected at various times in 
t le field, it is probable that the parasite eggs which are deposited just 
before the beginning of cold weather hibernate in that stage, while the 
eggs which are deposited early in the season hatch and hibernate as
