324 J. H. Emerton — Neio England Epeiridm. 



I have this spider from the White Mountains and young from the 

 Adirondaeks. The web has a narrow segment without cross lines, 

 Plate XL, figure 2, in which is a single thread by which the spider 

 passes from the center of the web to the nest. Near Hermit Lake 

 on Mt. Washington I saw one of these spiders capture a fly and 

 after tying it up with silk carry it along the thread to its nest. 



I have compared the females with one from Switzerland with 

 which it agrees very closely, but have not compared males. In the 

 male characters it agrees with descriptions of Z. montana. 



Zilla X-notata c. Koch.

This species is about the same size as Z. montana and similarly col- 

 ored. The legs are whitish with dark rings at the ends of the joints, 

 and less distinct ones in the middle. The spines of the legs are black 

 Avith black spots around the base. The cephalothorax is whitish with 

 a fine black line on each side and a wide dark stripe in the middle of 

 the head and nearly covering it, and tapering to a point near the 

 dorsal groove. In this dark stripe are three black lines converging 

 behind. The abdomen is marked with a grayish folium scolloped at 

 the edges, which are black in irregular spots. The middle of the 

 folium is whitish, lightest in front, where it is bordered by black. 

 In the hinder part are two or three pairs of black spots which are 

 sometimes united into transverse black stripes, in front of each of 

 which is a white line or pair of spots. Outside the folium is a white 

 line, and beyond this the sides are covered with oblique black bands 

 that in some individuals nearly touch each other. Under the abdo- 

 men is a middle black stripe from the stem to the spinnei'ets. The 

 epigynuin is black and much smaller than in Z. montana. The 

 males have the first and second pairs of legs much longer than the 

 female, the palpal organs are smaller than those of mo)itana, and the 

 tibia of the i)alpus is more slender. 



This spider was abundant at Wood's IIoll, Mass., in the summer of 

 1883, chiefly under the Light House wharf, where it lived in company 

 with Epeira sdopetaria in about equal numbers. The nest is a tube 

 usually open at both ends attached in a crack or corner. The webs 

 were of the usual Zilla pattern with a vacant segment near where 

 the thread passes to the center from the nest. Where the nest was 

 so placed that this thread formed a large angle with the plane of the 

 web, the web was sometimes complete as in Epeira. 



The web is begun like that of an Epeira, but after the smooth
