The cornicles are cylindrical, black, slightly flaring at the tips. The 
legs are yellowish, with the distal ends of the tibiae and the tarsi black. 
Black lateral tubercles are present on the prothorax and on the first 
six abdominal segments; the seventh and eighth segments each bear 
a pair of small black tubercles, one on each side of the median line. The 
length of this instar is 4+ days. 
Fourth instar.— Length 1.6 mm.; width 0.9 mm.; cornicles 0.28 mm. long. 
The general color is yellowish, with pink or reddish on the sides and 
around and between the cornicles. The whole body is covered with a

legs are yellowish, except for the distal ends of the tibiae and the tarsi, 
which are fuscous to black. Small black lateral tubercles are present 
on the prothorax and on the first six abdominal segments; on the seventh 
and on the eighth abdominal segment is a pair of small dorsal tubercles, 
one on each side of the median line. Thele ngth of this instar is 4+ days. 
Fifth instar— Mature apterous viviparous female——Length 1.84 mm.; 
width 1.04 mm.; cornicles 0.36—0.4 mm. long. i 
The recently molted female is dark purplish brown to olivaceous in

are present on the prothorax and on all the abdominal segments except 
the seventh and the eighth; the last-named bear small dorsal tubercles, 
one on each side of the median line. 
The apterous females vary greatly in coloration. The commoner form 
is the one just described. All gradations, to the form described as follows, 
may be discovered by a close examination of a wide series of individuals: 
general color yellowish, the sides faintly tinged with pink or reddish;
