Sublamily PSETTDOPHYLI.ID^E Burmeister. 



The Tertiary species described by Heer from Greenland under the 

 name of Locusta grcenlandica falls probably in this family; but there is no 

 close connection between it and the American species described below. 

 The distribution of the family at the present day is in general similar to 

 that of the last named. (July, 1884.) 



CYMATOMERA Schaum. 



This tropical or subtropical Old World genus does not properly find a 

 representative in the American rocks, but the species here described, too 

 imperfect for separate diagnosis, appeai-s to fall in its near vicinity and is 

 consequently referred here provisionally. No fossil species is known. 



CYMATOMERA MACULATA. 

 PI. 17, Fig. 7. 



A couple of spotted fragments from near the base of the tegmina of a 

 locustarian are placed here provisionally, because they agree better with 

 the group represented by that genus than with any other, though they 

 plainly can not belong to Cymatomera in any strict sense. The better of 

 the two fragments shows the base of a broad wing, with dark brownish, lon- 

 gitudinal veins, spreading widely, and the spaces between them or their 

 branches broken by very frequent, long cross-veins into short but very deep 

 quadrangular cells, while the whole surface, largely independent of the
