 but little longer than fourth. Thorax with sides less sinuate than in the

rura.") 



Small oval brownish or reddish species, having the head usually 

 with a distinct median impressed line; antennas as long or longer 

 than half the body, the third joint longer than fourth; thorax with 

 a median and two lateral impressions; elytra irregularly punctate,

 open behind; tibia' carinate on the outer side and without terminal 

 spurs; first .ioint dT hind tarsi not Ioniser tliiin the next two; tarsal 

 claws bifid in both scxex. They occur for the most part on herbs 

 growing in low, moist places, on the flowers of water-lilies, or on 

 the foliage of trees and shrubs bordering marshes. Ten of the 

 eleven species recognized by Horn probably occur in the State, while 

 hdeola, an introduced species, has also been taken. They were for- 

 merly classified under the genera Adiiiwiii'i and (rtilrruca.
