side of the folium along the lower edge of which and on the front end 

 of the abdomen were irregular red spots. They were found in white 

 pine trees, Essex, Mass. 



The males are a little smaller and have the abdomen more cylin- 

 drical. The mandibles are two-thirds as long as the cephalothorax. 

 The tibia of the palj^us is short, not much longer than tlie patella, 

 and both together are a little more than half as long as the femur. 



The second tooth on the u[)per side is the longest, and from this 

 four or five other teeth decrease gradually in length to the base.

Tetragnatha straminea, new.

The hinder row of eyes is curved backwards more than in kiboriosa, 

 and the lateral eyes are farther apart. The abdomen is silvery white 

 above and dark beneath with two light stripes. The cephalothorax 

 is light yellow with two parallel gray stripes. The legs are light 

 brownish yellow. The abdomen extends backward about half its 

 diameter beyond the spinnerets. It is long and slender, thickest 

 toward the front end and seldom swelled out in the middle as in 

 laboriosa. 



The males are smaller and more slender but their legs are no 

 shorter than those of the females. The palpi are longer than those 

 of laboriosa. - The tibia is as long as the tarsus and nearly twice as 

 long as the patella. The mandibles are about two-thirds as long as 

 the cephalothorax. The arrangement of the teeth ditfers but little 

 from that of laboriosa. 



Eastern Massachusetts ; New Haven, Conn. Adults from May to 

 July. 



Tetragnatha caudata, new. 



PL.A.TE XXXIX, FIGURES 16, 22. 



Two females from Maiden and Dedham, Mass., resemble very 

 closely T. straminea, except in the shape of tlie abdomen, which is 

 longer and has a tail about a quarter its length, extending backward 

 beyond the spinnerets. The shape of the abdomen of straminea 

 seems to be very constant, so that this is probably another species.
