No. 34-] HEMIPTERA OF CONNECTICUT: TINGIDAE. 699 



Uniform dark brown; head, antennae, legs, and body beneath, 

 darker. 



Paranota with two or three rows of areoles ; pronotal carinae 

 sHghtly divergent posteriorly. Subcostal and discoidal areas of 

 hemielytra with three or four confused rows of areoles ; sutural 

 with two rows anteriorly, this area parallel in short-winged form, 

 widening posteriorly in long-winged. Length, long-winged form, 

 3 mm. ; short-winged, 2.3 mm. 



Taken in sweeping and in hibernation under stones. Has been 

 found in Maine and in New York, but not as yet in Connecticut. 

 A, thomsonii Stal. 



Enum. Hemip., iii, 122, 1873. 



According to Stal, the bucculae in this species are contiguous in 

 front, a very exceptional condition in this genus. Length 

 2.5-3 "^^- This species may yet be found in New England. 



Dictyonota Curtis. 



Head with two divergent anteocular processes and two spines on 

 -vertex ; antennae thick, rugose, with strong setae. Pronotum with 

 three uniseriate carinae, a small hood not projecting over head, and 

 wide paranota, narrowed posteriorly. One of the many Palaeartic 

 species occurs in our territory, apparently representing a distinct 

 variety. 

 D. tricornis (Schrank) var. americana Parshley. 



Psyche, xxviii, 164, 1916. 



Head and disk of pronotum black, nervures brown, membrane 

 between the nervures gray. Legs and body beneath very dark 

 brown, antennae black. Length 3 mm. 



This form has been found only in Maine. 



Corythucha Stal. 



This genus contains a large number of small gauzy species, 

 w^hich have the antennae slender; hood large and more or less 

 regularly globose, with an anterior extension covering the head 

 and usually marked off from the posterior portion by a constric- 

 tion ; paranota extended forward ; hemielytra strongly constricted 

 and refiexed near base; lateral carinae of pronotum poorly devel- 

 oped as a rule; margins and dorsal surface usually more or less 

 spinose. Many of the species are closely related and our knowl- 

 edge of the limits of variation is far from adequate, but most of 

 the species are normally confined to a single food-plant, which 

 often aids in identification. The following key is restricted almost 

 entirely to the species now known to inhabit New England.
