Ofv. Finska Vet.-Soc. Forh., liv, Afd. A. No. 7, 62, 1912. 



Length 3.3-3.5 mm., width 1.3 mm.; ligneous black, antennae 

 and legs yellowish ; antennal segment i fuscous at base, sometimes 

 more broadly dark; hind femora usually with three or four

Occurs on elm (Ulmus) and white oak (Quercus alba). On 

 elm the bugs are found most frequently among aphid curled leaves, 

 feeding to some extent on honey dew. The writer has also 

 observed this species to feed on eggs of the elm leaf beetle 

 (Galerucella luteola).
