COLOMBIAN’ DERMAPTERA AND ORTHOPTERA 
1 40 
Tesinina and wings fully developed, broad, extending well beyond apex 
of abdomen; wings differing from those of P. phoratspoides (Walker) in hav- 
ing the transverse veinlets between the discoidal and median veins more 
numerous and delicate, the ulnar vein sending a few branches toward the 
median vein. Abdomen as characteristic of genus. 
Cephalic femora rather slender, with the characteristic parallel dorsal and 
ventral margins found in the species of this and related genera; ventro- 
cephalic margin supplied distad with widely placed, microscopic, rather short, 
spiniform hairs, with a single very short, stout but greatly atrophied distal 
spine; ventro-caudal margin unarmed, except for a similar distal s]nne. 
ether ventral femoral margins completely unarmed, the caudal margins 
moderately supplied with microscopic hairs. Tarsal joints short and stout, 
metatarsus unarmed and supplied with a large pulvillus, which extends to 
near its base, three succeeding joints with ventral surfaces fully occupied by 
large pulvilli. Moderately large arolia present betw'een the heavy bases of 
the simple, symmetrical, strongly curved tarsal claws. 
Allotype . — 9; same data as type. [Hebard Collection.] 
Very similar to male, size slightly larger, form broader. Pronotum with 
production of cucullate portion even less decided, so that the cephalic margin 
shows scarcely any emargination. Abdomen as characteristic of genus. 
Cleneral coloration similar in the sexes. General dorsal coloration shining 
cinnamon buff. Pronotum beautifully pictured with blackish brown as 
figured, cingulate cephalic margin russet. Tegmina wdth humeral trunk 
broadly blackish brown, veins of the same coloration, these becoming much 
less conspicuous toward the costal margin and distad; proximal portions of 
anal and marginal fields conspicuously pale, the impressed punctae there 
seen, under the microscoije, to be brown. Ventral surface of pronotum cin- 
namon-buff, with a large square suffusion of blackish brown laterad toward 
the latero-caudal angles, the tegmina with a smaller suffusion on their ventral 
surfaces toward the base of the marginal field. Head blackish brown, ocelli 
cream color, antennae uniform dark brown. Ventral surface ochraceous- 
buff, the coxae and lateral portions of abdomen heavily suffused with bister, 
four abdominal sternites with patches of ochraceou.s-buff in the center of the 
suffused area on each side. Cerci bister. Limbs ochraceous-bufif, with 
cephalic femora entirely, and other femora dorsad and ventro-distad, heavily 
suffused with bister, spines mars brown.
