Loculitii. — Mazon Creek, near Morris, Illinois. Peiinsyivaniaii; 

 Kittannino- { (Allegheny) stage. 



Similar to the preceding form, ])ut probably to be regarded as a 

 distinct species.

This form also perhaps belongs in another genus.

DISTATOBLATTA, new genus. 



Nearl}' related to I'/n/loh/atta. front wing similarly formed, 2^ 

 times as long as broad. Costal area extended oidy a little beyond the 

 middle of the wing. Radius proceeding in an almost straight course 

 to the end of the anterior margin, with <J simple or feebly ])ranched 

 ofl'shoots. Media strongly vaulted, continuing to the middle of the 

 apical border, with ;^ long veinlets l)ran("hing oil' forward. Cubitus 

 strongl}' developed, stretching obli({uely to the second third of the 

 posterior border, with 6 branches directed backward; in addition, 

 however, there are 3 compound ])ranclies running out foi'ward to the 

 apical margin. Anal art>a rather short. No cross veins.

 METAXYS, new genus. 



Front wing inclining somewhat to a cordate form, with rather 

 l)roadly rounded apex, twice as long as wide. Costal area broad, half 

 as long as the wing, inclining to a triangular shape, with 5 or i> veins, 

 some of which appear to ))e given otf at the base of the wing. Radius 

 strongly vaulted, not reaching to the apex; its branches directed 

 toward the front margin; the first is furcate, the second twice forked, 

 and third and fourth arc simple. Media not strongly arcuate; its ram- 

 bling compound branches directed forward toward the apical margin. 

 Cubitus with few very strongly branched otishoots taking up the 

 entire free inner maro-in. Anal area attainino- two-tifths the lenjitli of
