congcnei's, i. e., the abdomen more nearly approaches a globular shape. In 

 Massacliusetts I found one specimen with a white abdomen ; two with yellow 

 abdomens ; one with bright strawberry or burnt sienna marks ; one Tri- 

 folium that was blackish, the markings on the abdomen being white or 

 silveiy. These were all found in nests of several leaves, fastened together 

 in the ordinary ways. A similar variety in coloring characterized specimens 

 found in huckleberry patch- 



es and wooded hillsides just 

 back of the bay, at Niantic, 

 Connecticut. 



In habit and spinning- 

 work Trifolium resembles 

 Insularis, living in a curled 

 leaf with a trapline attach- 

 ment to her snare. ^ Hentz 

 in his description, based 

 u})on a si:)ecimen from 

 Maine, says that the spi- 

 der is found in houses and 

 near dwellings. Mrs. Mary 

 Treat reports the same 

 characteristic of the indi- 

 viduals seen by her in New 

 Hampshire. On the con- 

 trary I have rarely found 

 a specimen except in the 

 open fields or among shrub- 

 bery and often ([uite remote 

 from human habitations. 



A summer (1888) spent 

 on CajDC Ann, Massachu- 

 setts, gave me an admir- 

 able opportunity to ob- 

 serve the habits of this 

 species. Those who are 



familiar with New England hedge rows know how they are 

 formed ; granite boulders and blocks, brought from the meadow 

 or elsewhere, are i)iled along the boundaries between field and 

 road into low stone walls or fences. On either side of these 

 walls grow in unchecked profusion the native plants and wild flowers of 

 New England. There are shrubs of various sorts, golden rod, great ferns.
