brown, faint; the terminal and subterminal spaces concolorous. 

 Posterior wings uniform, grayish fuscous, fringed with white; discal 

 dots present. Beneath, the anterior wings are dark gray, with con- 

 trasting white and black atoms in the costal and apical spaces ; pos- 

 terior wings gray, with numerous black atoms and discal dots. 

 Expanse, 35 mm. 



Hab. Galena, Illinois. This fine species was received from Mr. 

 Thomas E. Bean. (No. 137.) 



Tseniocampa revicta nov. sp. 



Eyes hairy. Palpi brown and disconcolorous. Head and thorax 

 uniform, very light gray. Anterior wings of a slightly darker gray ; 

 the median lines dentate and very faint, the subterminal line clear 

 black, very conspicuous, divided into short lines by the veins, obso- 

 lete before the costa and inner margin ; ordinary spots large and 

 concolorous, the orbicular open above and below, the reniform also 

 imperfect, with a black spot in its base; both are surrounded by clear 

 brown annuli, the tip of the claviform spot also of the same color. 

 Posterior wings gray, with white fringes and black discal dots. 

 Beneath, with discal dots and an interrupted common median line. 

 Expanse, 35 mm. 



Hab. Galena, Illinois. A single specimen taken by Mr. Thomas 

 E. Bean. (No. 197.) The black subterminal line is the most im- 

 portant character of this insect. 



Homoptera penna nov. sp. 



This species is allied to Homoptera galbanata Morr., which Mr. 

 Bean has captured in the same locality; it is separated from it by the 

 partial obsolesence of the median undulate lines and by the presence 

 on both wings of a very heavy continued black band following the 

 exterior line, at a little distance. 



This character will also separate it from all the species of the 

 genus known to me; several of them have a more or less distinct 

 black line in this position, but in none of them is it so broad, heavy, 

 so evenly continued over both wings, and so strongly contrasting 

 with the ground color which, in the new species, is light gray. Ex- 

 panse, 40 mm. 



Hab. Galena, Illinois. Received from Mr. T. E. Bean, (No 147.)
