The females of this form are rare. 1 have a single specimen taken in 

 Fairlield County during October which maybe a fnlly de\'e]oi)ed female

 dark brown with white annulations at all the Joints, including those of 

 tarsi, and a transverse wliite blotcli on dorsum of abdonu'n. If this is 

 the female longipes the forms with i)lain biown legs must be immature 

 conditions of it.
