slender ov long as in TetragtuUlui. The colors are bright green and 

 yellow with black and silvery markings on the abdomen. The max- 

 illfe arc long as in Meta. The lateral eyes are widely separated from 

 the middle ones. The mule palpi are long and the palpal organ large 

 and rounded and only partly covered by the tarsus. Keyserling 

 includes these hi the genus Meta^ and Walckenaer in Tetragnatha, 

 2nd tamily.

 longer, the tiist pair being 17"'"' long. The male palpi are longer 

 than the cephalothorax. The patella is about as short as thick, and 

 the patella and tibia together are nearly as long as the femur. The

Tetragnatha. 

 In TelrfU/natlia the body is long and slender. The eyes are in 

 two rows variously curved. The legs are long and slender, and when 

 the spider rests in the web, are extended in front and beliind parallel 

 with the l)ody. The colors are light brown and yellow with silvery 

 spots and bauds above and darker with yellow stripes beneath. 

 Sometimes the whole body is bright green with white and red mark- 

 ings. The mandibles are long, and longer in males than females. 

 Besides the teeth on the inner side of the mandibles, the males have 

 an additional tooth on the upper side near the tip which curves for- 

 ward and is usually forked at the end. The webs are otten inclined or 

 horizontal and are usually near water on low [)lants.
