As noted above the present authors have twice failed to recog- 

 nize single specimens of the present species as distinct from the 

 then known species. This was chiefly due to the fact that 

 scarcely any material from the salt marshes of the Atlantic 

 coast was then availalile, and, in a genus showing such great 

 variability as the present, no definite knowledge of the forms 

 already described and the number of species really present could 

 be gleaned from the inadequate series at that time in hand. 



The present species bears a shght superficial resemblance^ to 

 C. brevipennis and C. spartinae, but may at once be separated 

 from these by the decidedly more rol)ust and compact structui'c, 

 unusually prominent eyes, heavy truncate distal portion of the 

 male abdomen, which in life is a bright and striking yellow and 

 bears concolorous cerci which are distinctive (but plainly a de- 

 velopment of the type found in C. stidomerus and C. hygrophilus), 

 broad and weakly sigmoid ovipositor, and short, heavy limbs 

 with the vcntro-cxternal margins of the caudal femora l)earing 

 normally a number of heavy spines. 



Along the coast of Georgia and Florida, where spartinae is 

 also found in the salt marshes, the present insect averages decid- 

 edly larger in size than that sjjccies.
