A NEW TINGID FROM NEW YORK STATE. 



By J. R. DE LA Torre Bueno, White Plains, N. Y. 



Genus Acalypta Westwood 1840. 



Orthosteira Fieber 1844. Orihostira Fieber 1861. 



1. Pronotal keels subparallel or very slightly diverging posteriorly; costal 



area uniseriate in greater part; third joint of antennae long, more than 

 three times the fourth Acalypta lillianis, n. sp. 



2. Pronotal keels diverging posteriorly; costal area biseriate in greater 



part; third joint of antennae short, not quite twice as long as the 

 fourth A. thomsonii Stal. 



Acalypta lillianis n. sp. Black, posterior part of pronotum and hemely- 

 tra dark gray; third joint of antennae of equal thickness throughout, four 

 times as long as the fourth, longest, second joint shortest, first stoutest 

 and shorter than fourth, v^^hich is not quite so stout as second ; pronotum 

 tricarinate, keels nearly parallel, or at most slightly diverging posteriorly, 

 the middle keel highest; hood small, not projecting over head, slightly 

 angulated in front, somewhat higher than the median keel ; sides f olia- 

 ceous, more or less biseriately reticulate, anteriorly rounded ; costal' mem- 

 brane uniseriate in greater part. Abdominal segments broadly banded 

 with rufous. 



The macropterous form has the membrane complete, reticulately veined ; 

 in the brachypterous, it is much reduced and is biseriately reticulate. The 

 pronotum in the former is quite high, but in the latter much reduced in 

 area and nearly flat. The hemelytra are one third longer than the body 

 in the macropterous form, and in the brachypterous exceeds it but very 

 little. The brachypterous form is nearly oval, while the macropterous is 

 elongate. 



Macropterous, long 3 mm.; wide 1.6 mm. (type). 



Brachypterous, long 2.3 mm.; wide 1.2 mm. (type).
