Se 
is a simple row of hairs which are from 56 to 62 
microns long, and have the distal extremity dilated 
and with one or two slits; those with but one 
slit being the most numerous. The distance be- 
tween the hairs is from 187 to 219 microns. The 
anal plates are relatively small, and dark brown in 
color, and have the interior margin 0,279 min. 
long. The entire dorsal surface is full of large 
elands, oval, round, or sub-circular in form, and 
of various sizes; the largest being 11? microns in 
diameter. P 
The eggs are elliptical in form, with a longi- 
tudinal diameter of from 0.356 mm. to 0.418 mm. 
and a transverse diameter of from 0.100 mm. to 
0.116 mm., and are light yellow in color. The eggs 
are very abundant, as each female, at one time, lays 
many thousands of them. 
The newly hatched larvae are small, with the 
body flat and cval in form, 0.512 mm. Jong and 
0.287 mm. wide, yellowish brown in color, with 
the eyes small and black. The margin of the body 
is crenulated, and is furnished with a simple row 
of 34 hairs, of which the two median ones, on the 
vosterior extremity, are the longest. The stigmal 
areas are caracterizised by one thick, obtuse spine, 
about 31 microns in length. At the pcstericr ex- 
tremity there is also one pair of terminal setae, 
about 0.275 mm. in length. The antennae appa- 
rently have six joints, and are about 0.129 mm. in 
length. All of the joints have hairs, and the last 
joint has several lateral and terminai hairs, one of 
these last being 94 microns ‘ong.
