The characters in the table easily differentiate this from the 

 preceding species. Though its author states that it seems to 

 approach the European O. marginatus Latreille, a comparison of 

 the two species shows immediately notable differences in facies and 

 markings, without considering the structural details. 



This species, not heretofore recorded from Connecticut, is found 

 not uncommonly in New York within a few miles of the 

 Connecticut border.

Family NERTHRIDAE. 

 ( Gelastocoridae ; Galgulidae. ) 



By J. R. DE LA TORRE-BUENO. 



There is only one genus of this curious family in the East, 

 represented by an uncertain number of undescribed species. 



Gelastocoris Kirkaldy. 

 (Galgulus Latreille.) 



The family characters serve to distinguish it. The species of 

 the genus all have a peculiar shagreened mottled aspect. They are 

 commonly called toad-bugs, on account of their markings, promi- 

 nent eyes and squat shapes. So far as known, all frequent the 

 shores of streams and ponds and some are found in bogs and 

 marshes, hopping and running about the dryer parts, in chase of 

 their prey. 



The following key has been prepared from the type specimen of 

 G. barberi; and from specimens from Raleigh, North Carolina,
