MEXICAN DERMAPTERA 
abdominal segment siibqiiadrate and forceps extremely heavy 
(Plate XXVIII, figure 2). Width of disto-dorsal abdominal seg- 
ment 4.1, length of forceps 4.8, basal width of forceps 1.2 mm. 
Additional material may show this to be a distinct species; if this 
proves true Dohrn’s name, saussurei, is available.

The present species might easily be confused with A. annulipes, 
and the features of real differential value have been so casually 
stated in the literature, that it is not surprising to find that Burr 
has assigned this name to the synonymy under that species. 
Females may be separated from those of annulipes by the 
average decidedly larger size;^ head with margins of cheeks, 
behind eyes, almost straight, parallel, to the broadly rounded 
latero-caudal angles, thus giving the caudal portion of the head a 
distinctly more quadrate appearance than in annulipes',^ latero- 
caudal angles of fifth and sixth dorsal abdominal segments sharply 
rounded, not broadly rounded as in annulipes', forceps decidedly 
* As noted by Bormans. Das Tierreich, xi, p. 49, (1900). 
• This feature is noted in the original description, and, though subtle, appears 
to be of marked diagnostic value.
