PANAMA DERMAPTERA 
The present male has the forceps with sinistral arm more slender 
and shorter than the dextral, the dextral alone supplied at end of 
proximal third with a small inner tooth. The present specimens 
show the following measurements: length of body, cf, 9.2, 9, 
7.7 ; of forceps, d', 3.4, 9 , 2.7 mm. 
Prosparatta humilis new species (Text fig. 1; plate XXVI, figs. 1 and 2.) 
This species shows a very strong general superficial resem- 
blance to small examples of Vostox brunnei'pennis. Compared 
with the genotype, P. incerta (Borelli), the present species is 
found to be less slender, with less elongate pronotum, more acute 
male pygidium, male forceps with internal tooth more proximal 
and female forceps with distal flange of ventro-internal margin 
weaker and not abruptly terminated. 
Type . — d] Cabima, Panama. May 25, 1911. (A. Busck.) 
[U. S. National Museum.] 
Size medium large for genus, form moderately depressed. Head with occi- 
put impressed, cheeks longer than eyes. Anten- 
nae with first segment large, broadening in mesal 
third so that the distal portion is the more ample; 
second minute; third as long as first, but much 
more slender; fourth decidedly shorter, twice as 
long as its mesal width ; succeeding segments in- 
creasing regularly in length distad. Pronotum 
longer than broad, smooth, with a medio-longitu- 
dinal linear sulcus very feebly indicated; rect- 
angulate cephalad, broadly convex truncate 
caudad, lateral margins straight, shovdng an 
almost imperceptible divergence caudad ; prozona 
tumid, this becoming very weak caudad in the 
middle of each side; metazona deplanate. Teg- 
mina smooth, with distal margin truncate; wings 
with exposed area nearly half as long as tegmen. 
Abdomen with fourth and fifth dorsal segments 
showing laterad a weak, rounded carina; abdom- 
inal surface polished, but with surface micro- 
scopically very closely ruguloso-punctulate, ex- 
cepting ultimate dorsal segment which is smooth, 
with length equal to half its width, showing a 
weak triangular depression meso-distad and with 
transverse distal margin thickened, feebly con- 
cave mesad and laterad. Pygidium small, about
