A CONTRIBUTION TO THE KNOWLEDGE OF THE 
DERMAPTERA OF PANAMA^ 
BY MORGAN HEBARD 
In recent years extensive collecting in Panama has been under- 
taken and the exceptionally fine series of Dermaptera thereby 
assembled is here considered. Nearly the entire collections were 
made by E. A. Schwarz and A. Busck for the National Museum; 
a few specimens taken by J. Zetek, for that institution, and by 
D. E. narrower and the author, for the Hebard Collection, are also 
included. A general study of the American Dermaptera available 
has been undertaken, the results of which work are in the course 
of publication. 2 Considerable revision has been found necessary 
and in the present paper many, now obvious, mistakes are recti- 
fied in the Spongiphorinae, Labiinae and Sparattinae. 
In the present paper twenty-two genera and twenty-nine 
species are recorded, of which five genera and six species are 
described as new. The only species previously recorded from 
Panama, but not represented in the present series, is Echinop- 
salis thoracica (Serville). A series of one hundred and eighty-five 
specimens has been considered. 
Our thanks are due to hlr. A. N. Caudell for the privilege of 
studjdng the material belonging to the National jMuseum and the 
retention in the Hebard Collection of duplicate material. 
It is important to note that “length of body” in the present 
paper signifies the distance from the buccal region of the head to 
the apex of the penultimate ventral abdominal segment, the head 
in normal position being carried horizontally. 
' The second and succeeding papers of this series will deal with the Orthop- 
tera of Panama. 
2 The first paper has already appeared, “ Notes on the Earwigs (Dermaptera) 
of North America, north of the Mexican Boundary,” Knt. News, xxviii, pp. 
311-323, (1917). The others will treat of the Dermaptera of Mexico; Gen- 
eral Notes; of the Dermaptera of the West Indies excluding Porto Rico, and 
of the Dermaptera of Porto Rico.
