90 REPORT OF NEW JERSEY STATE MUSEUM. 



C. lyricen DeG. Taken only at points north of New Brunswick, but prob- 

 ably occurs throughout the State with the preceding, which it closely 

 resembles. 



C. canicularis Harr. Throughout the State; more or less common. 

 Occurs with "linnei," than which it is smaller, but otherwise nearly 

 allied. 



C. davisi Grossb. Paterson IX, 4 (Gr) ; Anglesea VIII, 25 (Coll). 



CARINETA Am. & Serv. 



C. parvula Say. Occurs all along the Atlantic Coast, and, according to 

 Ashmead, should reach New Jersey. It is certain that a form not 

 yet taken has been heard at Anglesea by myself and others, and it 

 is probably this species. 



Family MEMBRACIDyE. 



Contains the "tree-hoppers" which are odd-looking creatures, more or 

 less wedge or beech-nut shaped, the prothorax often abnormally developed 

 into horns, spines or crests. They leap and fly readily and are commonly 

 found on trees and shrubs. The eggs are usually laid in slits made in 

 twigs, shoots or other vegetable tissue, and many of the larvae or nymphs 

 envelop themselves in frothy masses. A few of them excrete honey dew. 



Few of the species are really abundant and none of them cause injury 

 by feeding. The "buffalo tree-hopper" and its allies do some harm by 

 their egg-laying. The slits are made in the soft tissue of the twigs and 

 shoots of fruit trees, and these wounds seem to be poisonous. At all 

 events, instead of healing, the slits form open wounds which enlarge, 

 check growth, make weak points where breaks occur when fruit is borne, 

 or any strain is put upon the injured wood. 



The punctures are readily noticed in winter and should be cut out when 

 pruning and the cuttings destroyed. Insecticides are not indicated. 



Sub-family SMHJIN,. 



CERESA Am. & Serv. 



C. diceros Say. Throughout the State VI, VII, VIII, IX. 

 C. bubalus Fab. Common, VI-IX, throughout the State. This is the

C. boreal is Fairm. Chester VIII (Coll). 



C. basalis Wlk. Chester IX, 1 (Coll), and probably throughout the High- 

 lands.

 tually taken, although its occurrence is probable.
