This new species seems to be most correctly placed in the 

 genus Leptobyrsa 3 -, which was founded by Stal on a single 

 species b from Rio Janeiro, Brazil. It agrees very well with 

 the diagnosis he has given of his genus. It also has much 

 affinity with the genus Stephanitis Stal, but the hood is com- 

 paratively smaller and the lateral carinas extend over the 

 whole length of pronotum, not abbreviated in front. Dr. C. 

 Berg c recorded another species from Argentina, South 

 America, and Dr. G. C. Champion d described several new 

 species from Central America. Our species resembles two 

 species, Leptobyrsa steinii Stal and Leptobyrsa translucida 

 Champion ; from the first it differs in having the membranous 

 margins of pronotum less advanced in front, the sides not 

 straight but evenly rounded, and from the latter it can be 

 distinguished by the more prominent hood, also in having 

 two sharp impressions across the elytra. 



This tingitid lives quite abundantly on the mountain laurel 

 (Kalmia latifolia) and on Rhododendron maximum. It has 

 been found up to the present time on the Atlantic side from 

 Florida as far north as Boston, Mass., and westward to Ohio. 

 The insect is recorded as injuring Rhododendron foliage.
