long posterior process, and markings of dark brown. The nymphs are 

 found on the same hosts as the adults, and all stages may be collected 

 during July and August. 



Because of the fact that most of the species of the genus Telamona 

 inhabit oak, it has been impossible in the course of this study to positively 

 identify the eggs without rearing the species in each case, and this has not 

 been accomplished except in a few instances. The nymphs do not live 

 when confined under netting on the tree, and do not survive transportation 

 and transfer to new hosts in the laboi'atory; and it will require very 

 patient work for a number of years to work out the life histories for all of 

 the Telamonas. 



In the few cases in which nymphs have been successfully reared to 

 maturity a wide variation has been found in the individuals of a single 

 egg mass, suggesting that the species here recognized may not all stand 

 after careful biologic data have been obtained. 



It has been suggested that a careful revision of the genus is needed, and 

 such a revision should be based largely on a study of life histories. 



Technical description. — Varies greatly in shape and size of dorsal crest and in coloration; 

 crest usually higher before than behind, marked with a brown fascia which extends to the 

 lateral margin; metopidium hairy; tegmina tipped with brown. 



Head broader than long, greenish marked with reddish patches, sculptured, sparingly 

 punctate, pubescent with short black hairs; base high and sinuate; eyes prominent, brown; 

 ocelli large, protruding, nearer to each other than to the eyes; clypeus nearly flat, greenish, 

 smooth, pubescent, sutures distinct, tip extending far below inferior margin of face. 



Pronotum finely punctate and pubescent; metopidium convex, median carina prominent; 

 dorsal crest sloping, longer than high, tip truncate, posterior margin pale; posterior process 

 gradually acute, not reaching tips of tegmina. 



Tegmina hyaline, WTinkled, bases deeply punctate with black, tips marked with deep 

 brown triangular fascia. Undersurface of thorax flavous and pubescent; abdomen brown, 

 segments margined with paler. Legs yellowish; tibiae hairy. 



Length 9 mm.; width 4. .5 mm.
