Ancistrogaster sp. 



One immature 9 ; Jalapa, Vera Cruz, Mexico. Collected by J. 

 T. Mason (U. S. N. M.). 



»olohopliora ruficeps (Burmeister). 



1838, F[orficnla] ruficeps Burmeister, Handb. cler Ent., ii, p. 755. 



Two males ; Jalapa, Vera Cruz, Mexico Collected by J. T.

These specimens are quite uniformly colored, the only apparent 

 contrast being the reddish head. In one specimen the forceps are 

 much shorter (7.75 mm.) than in the other (12.5 mm.). 



Apterygida linearis (Eschscholtz). 



1822, Forficula linearis Eschscholtz, Entoniographien, i, p. 81. 

 Forficula tseniata Dohrn, Stettin Ent. Zeit., xxiii, p. 230. 



Sixteen specimens; Jalapa, Vera Cruz, Mexico. August, and 

 September. Collected by Otis W . Barrett. (Eight; three males, 

 five females.) Same locality. Collected by J. T. Mason. (Two; £ 

 and ?.) (U. S. N. M.) Texolo, Vera Cruz, Mexico. 1899. Col- 

 lected by S. N. Rhoads (1<?). Cuernavaca, Morelos, Mexico. 

 September. Collected by Otis W. Barrett (5 males). 



Bormans and Krauss* have rather vaguely noticed that the name 

 linearis of Eschscholtz was based on the same insect as Dohrn's 

 fa ii in ta, a fact which cannot be questioned when the original de- 

 scription of linearis is examined. All the characters assigned are 

 perfectly recognizable, the size alone being somewhat unusual, 

 though the writer has examined specimens but little larger. 



Apterygida californica (Dohrn). 



1865, F[orficuld] Californica Dohrn, Stettin Ent. Zeit., sxvi, p. 85. 



Two specimens, $ and 9 ; Gualan, Guatemala. Collected by

These specimens extend the range of the species south of the 

 former southern limit — Teapa, Tabasco, Mexico.
