 Plate III, figures 2, 2a. 



I have several times found at Beverly, Mass., spiders which appear 

 to be the European lineatum. The colors are similar to T. frondeuin, 

 but the markings are different. The thorax lias a fine black line in 

 the middle and one on each side near the edge. The sternum has also 

 black edges and a black line in the middle. The abdomen has six 

 pairs of black spots, under which in some specimens were bright 

 crimson bands. There are four black spots around the spinnerets and 

 a black stripe under the abdomen. 



All my specimens are young females from Beverly, Mass., and 

 an island in Salem harbor.

 This genus is much like Ero, but the cephalothorax is lower and 

 long. The head is narrow and prolonged forward. The mandibles 

 are long. The abdomen is high and wide in front and resembles 

 Epeira in shape and markings. The logs are long and spiny as in 

 jEVo, but the rest of the body is less hairy. Tiu; palpi of the male 

 have a long tube and a })roccss at the base of the tarsus much as in 

 Era.
