I have not seen any winged individuals of this species. 

 Immature specimens are of an uniform bright brownish 

 red upon the head and thorax, with the abdomen growing 

 darker posteriorly and laterally ; the legs are of a bright 

 shining yellow, a little dusky, with rather long delicate 

 spines placed irregularly upon the edges, the femora 

 being tipped with one slightly curved ; cerci blackish ; 

 eyes black ; palpi dusky ; antennas light brown ; third 

 joint of antennae as long as the succeeding five taken 

 together, and twice as large as the second ; in E. ger- 

 manica it is only slightly larger than either of the succeed- 

 ing, and of the same size as the second. Length, .4 in. ; 

 breadth, .2 in. An ootheca of this species (or so labelled 

 by Harris), is similar in general appearance to that of E. 

 germanica, but is shorter ; it measures Length, .2 in. ; 

 breadth, .1 in. ; thickness, .07 in. There are nine trans- 

 verse depressions. " Under stones ; very common in woods.
