NATHAN BANKS. 27 



costal veinlets branched ; outer margin of forewing concave, hind- 

 wing barely so; in hindwings one cross-veinlet below the ptero- 

 stignia, and three near posterior margin ; the radial sector with four 

 branches. 



Type. — L. Jiavicornis Walk. 



Differs from Isoscelipteron Costa in having the subcosta end in 

 the radius, and the fevver branches of radial sectors, as well as minor 

 points. I have not seen the type of Berotha Walk., which is from 

 India, but judging from the description it is a different genus from 

 ours. I know but two species. 



1. Apical margin siuuateiy concave, and with the bind margin sinuate before 



outer angle flavi<'oriiis. 



Apical margin evenly concave textliia.

 dots; antennte pale yellow, the basal joints with a few brown spots; prothorax

 pale, with brown dots, transverse veins entirely brown ; some larger spots at 

 forks of veins in apical part of wing, margin mostly brown, but with some 

 patches of white, two in the concave part; pterostigma brown ; hindwings with 

 apical venation and pterostigma brown. Forewings falcate at tips, apical mar- 

 gin sinuately concave, and the posterior margin slightly concave before outer 

 angle; five branches to radial sector. Expanse 22-24 mm. 



Specimens from Falls Church, Virginia, July 4th ; Prospertown 

 and Lakehurst, New Jersey, May 25th. Walker's specimens came 

 from Georgia, and Hagen records it from AVashington, D. C.
