Numerou.s forms from Europe and America. 

 Type of genus, S//sci/>/>/i/eI>n/ oKjlyptina (Germar), 

 I am convinced that, after a careful investigation of very abundant 

 material, many of the species separated b}^ me will be combined. 

 However, in order that an arl^itrary association may be avoided, it 

 will be necessary first to determine exactly the limits of variation in 

 recent forms. So long as that is not done, I consider it advisable to 

 separate the fossil forms rather than unnaturally and arbitrarily to 

 unite them. 



SYSCIOPHLEBIA ARCUATA (Sellards). 



Gerahlattina arruata Sellards, Amer. .four. Sci. (4), XVIII, 1904, p. 216, fig. 1, 

 pi. I, %. 7. 



Locality. — Lawrence, Kansas. Upper Coal Measures; Le Roy 

 (Lawrence) shales. 



SYSCIOPHLEBIA V7HITEI, new species. 



Locality. — Wills Creek, near Steuben ville, Ohio. Conemaugh for- 

 mation; shales above the Ames limestone. 



Length of the front wing, 

 iJ6 mm. Costal area narrow, 

 extending three-fourths the 

 length of the wing. The 5 

 branches of the radius are 

 directed obliquely forward, 

 the first being furcate, the 

 second twice divided. Media 

 with few oft'shoots directed 

 forward. Cubitus strongly arcuate, with 7 or 8 simple branches. 

 Anal area with 7 veins. The wing has a more kidnej'-shaped form, 

 and is more than 2^ times as long as wide. The veins are distinctly 

 bordered. 



The specific name is in honor of Dr. David White of the U. S. Geo- 

 logical Survey. 



ILolotype. ~C?it. No. 38697, U.S.N. M. 



SYSCIOPHLEBIA SCUDDERI, new species. 



EtohlaUhia gracilenta Scuijder (part), Bull. U. 8. Geol. Hurv., No. 124, 1895, p. 95, 

 fig. 7 (not fig. 6). 



Locality. — Richmond, Ohio. Conemaugh formation; shales above 

 the Ames limestone. 



It seems to me that Scudder has combined several species under 

 Etohlattma gracilenta.
