The females are usually larger and the males smaller than in mav- 

 morea. The largest female I have seen, a bright orange one from 

 New Haven, Conn., measured 19""" long ; first leg 24""", One of 

 the usual size measured 13""" long; first leg 17""". The ce})halo- 

 thorax is dull j^ellow with slightly darker lines in the middle and at 

 the sides as in marmorea. The femur and patella of all the legs are 

 bright orange, darker toward the ends with sometimes a darker ring 

 in the middle of the femur. The other joints are white with brown 

 ends as in marmorea. The sternum is light bi'own on the edges 

 and bright yellow^ in the middle. The light markings of the abdo- 

 men are bright yellow or occasionally deep orange. The dark 

 markings are dark brown or purplish. The markings are all sharply 

 defined. The folium is deeply scolloped and bordered by a wide 

 yellow line, outside of which is a row of irregular yellow spots. The 

 spots inside the folium are in the same positions as in marmorea but 

 are much larger. The wider side of the abdomen is marked as in 

 marmorea. 



The males are V""" long, first leg 13""" and marked like the females. 

 The dark stripes on the ce})halothorax and the rings on the legs are 

 plainer than on the female. The co.vie of the second legs have only 

 a slight hump in place of the spine. The tibiie of the second pair 

 are enlarged and spiny as in marmorea. 



This species is more common in Massachusetts and Connecticut 

 than marmorea. It lives with trifoltum on high bushes three or four 

 feet from the ground, usually near water. It makes a tent under 

 which it is usually found holding a thread leading from the center of 

 the web. The males are found near the tents of the females in 

 August and September. This species was found by Hentz in Ala- 

 bama.

 This species may readily be mistaken for young insularis. It is 

 7""" long, with a wide, round, white or yellow abdomen, with two dark 

 stripes extending from near the middle of the front around the sides 

 under the abdomen nearly to the spinnerets. Under the abdomen 

 there is a light spot just back of the epigynum surrounded by a large 

 dark area which extends back nearly to the spinnerets. The epigy-
