NO. 34-] HEMIPTERA OF CONNECTICUT: MEMBRACIDAE. I 79 



The species may be recognized by its small size, reddish carina 

 and long, recurved horns. 



The life history is not known. 

 Hosts : Locust, oak.

Stictocephaia Stal. 



This genus is close to Ceresa but may be distinguished super- 

 ficially by the absence of suprahumeral horns. This character, as 

 has been pointed out by Van Duzee (Studies in North American 

 Membracidae, p. 41), is an entirely superficial one and does not 

 hold good in the comparison of the two genera as entities since 

 there is a gradation between the horned and hornless species, but 

 it serves perfectly in separating the genera in Connecticut since 

 the intermediate forms do not occur in this fauna. A more 

 natural character is the difference in the genital apparatus pointed 

 out by Fowler (Biologia Centrali-Americana, ii : 1. p. 97. 1894) 

 and apparently good in generic diagnosis. 



The two species of the genus to be found in Connecticut may be 

 distinguished as follows : 



Size large ; color uniform green .inermis 



Size small ; undersurface of body black lutea 



S. inermis (Fabricius).

A fine large species very abundant throughout eastern United 

 States on clovers and grasses and usually taken in sweeping. 



The eggs are laid in the young stems of apple just beneath the 

 bark in groups of four or five. The egg puncture is a ragged 

 one and fails to heal smoothly, leaving a characteristic scar which 

 has been well figured by Hodgkiss (The Apple and Pear Mem- 

 bracids, p. 98). Oviposition occurs over an extended period 

 during July, August and September. The eggs winter over and 

 hatch about the first of May. Almost immediately the nymphs 

 migrate to the grass and weeds where they spend most of their 

 lives, the mature females returning to the apple to oviposit. The 

 complete life history of a closely related species, S. festina, has 

 been worked out by Wildermuth (Wiklermuth, V. L., Journ. Agr. 

 Research, iii. 343-362. 191 5) and the life history of S. inermis is 

 probably very similar. 



Hosts : Sweet clover, red clover, white clover, timothy, apple.
