a red band near the upper margin of the joint, the femur of the first 
two legs was yellow green with gray at the upper margin, and a 
large black splotch at the lower margin on the side; the femur of 
the last two legs is the same color but lacks the black spots; the 
tibia, metatarsus and tarsus are yellow gray with darker gray 
green at the upper and lower margins of each joint. From now on 
until the last moult there was no change. At the last moult the sex 
of the spiders appeared and the color pattern was completely 
formed. Though the young with the complete color pattern were 
not as bright and brilliant as the mother caught with the eggs, yet 
they would very likely improve with age. The color pattern of 
this form was the hardest to follow and understand. At each moult 
it seemed to be a process such as is necessary in the reproduction 
of a colored plate, one color placed on top of the other until the 
final whole is obtained. 
A female Peucetia viridans with eggs was collected in the early 
summer (July Ist) on a squash vine. (Plate III.) The female 
was colored differently from the one just described above, and also 
different from the one described by Comstock, yet this one is identi- 
fied by Banks as belonging to this genus and species. The cephalo- 
thorax of the adult was a light yellow green with a silver eye 
space. There were two black lines on the lower margin of the 
cephalothorax. The abdomen is a dark brown green ground color, 
with a band of light green on either side of the median line near 
the upper margin. Near the middle of the abdomen are two white 
spots. A light brown triangular pattern is found in the median 
line near the upper margin. The legs and palpi have a light 
green coxa and trochanter, an orange femur and a yellow tibia, the 
metatarsus and tarsus with a green band both at the upper and 
lower margin of each joint. The trochanter is flecked with black 
spots. The legs are covered with strong spines. The spinnerets 
are dark brown. 
The young emerged after two weeks and were dark brown, the 
abdomen being darker than the legs and cephalothorax. At this 
time there was no semblance in the young to the adult in either 
shape of body or color. The first moult occurred in one week. 
The shape of the body had changed to the elongate abdomen and
