bility that these two forms represent variants or races of the same 
species. ; 
Compared with 4. maritima (Géné), the present species may 
be readily separated by the darker and annulate antennae, with 
joints heavier; pronotum which does not widen caudad; more 
highly polished dorsal surface, due to the less numerous micro- 
scopic hairs; ultimate tergite with a more pronounced ventro- 
lateral keel; preceding tergite of male similarly produced, but with 
minute, scattered, impressed punctae and a moderate keel, not 
ruguloso-striate, and heavier and proportionately shorter forceps, 
which, in the male, differ decidedly in being much less strongly 
curved and of the same type developed in E. annulipes (Lucas). 
Compared with annulipes, the insect is easily distinguished by 
its much larger size, less globular antennal joints, immaculate 
limbs and numerous other features. It is evident that Burr was 
in error in believing eteronoma to be a synonym of annulipes.*

“Tt is regrettable that in many places Burr has indicated synonymy, 
apparently in haste, without justification, for examination of our material 
shows that, as in the present case, distinct species had actually been described. 
*Exclusive of the forceps, as is customary. 
*Tt is evident that Burr’s paper on the National Museum collection of 
Dermaptera was hurriedly prepared, for many of his identifications, as 
already noted, are incorrect.
