bility that these two forms represent variants or races of the same 

 species. 



Compared with . /. iiuirifiiini (Gene), the present species may 

 be readily separated by the (hirker and annulate antennae, with 

 joints heavier; pronotnm which does not widen caudad ; more 

 hi,f;hly 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 luoderate keel, not 

 rug-uloso-striate, and heavier and proportionately shorter forceps, 

 which, in the male, dififer decidedly in being- much less strongly 

 curved and of the same type developed in B. aiinulipcs (Lucas). 



Compared with aiinulipcs, 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 cfcronoma to be a synonym of annnlipcs.^

^ It 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. 



■' It is evident that Burr's paper on the National Museum collection of 

 Dermaptera was hurriedly prepared, for many of his identitications, as 

 already noted, are incorrect.
