COLOMBIAN DERMAPTERA AND ORTHOPTERA 
at the caudal margin; lateral margins of pronotum irregularly 
denticulate. Alesonotum and metanotum with tegminal and 
wing pads distinct, produced, and with a distinct medio-longi- 
tudinal carina, this carina forming with the caudal margin a 
small acute raised projection meso-caudad on each of these seg- 
ments. Median segment with a similarly formed but larger, yet 
small and foliaceous plate meso-caudad, three succeeding tergites 
weakly carinate medio-longitudinally and similarly specialized 
meso-caudad, the remaining tergites with specialization weaker, 
similar to but more decided than that of metanotum; four proxi- 
mal tergites iirodiiced latero-caudad in rounded lamellae, these 
smaller for the two succeeding tergites and much smaller for the 
two following these. 
Supra anal plate elongate trigonal, weakly carinate medio- 
longitudinally, with apex rather broadly rounded. Cerci mod- 
erately stout, not extending beyond apex of supra-anal plate, 
with joints well defined. Subgenital plate as in females of Pogo- 
nogaster, except that the cleft distal portion is not differentiated 
proximad from the jiroximal portion by a transverse depression. 
Limbs and their armament as in Pogonogaster. Cephalic coxae 
with dorso-external margin microscopically denticulate, dorso- 
internal mai-gin showing this condition even weaker, conspicu- 
ously lobulate distad. C'ephalic femora slender, wuth three elong- 
ate discoidal spines, ventro external margin minutel}' denticu- 
late and armed with four elongate spines, in addition to a small 
genicular spine; ventro-internal margin, in addition to a small 
genicular sjiine, with seven elongate spines, of which the second 
is much the longest. Cephalic tibiae armed proximad on ventro- 
internal margin with two minute spines,®* curved distad, fol- 
low(‘d by a very elongate heavy spine, with a single spine of 
about half that size distad on ventro-external margin, exter- 
nally distad with a similar .sjiine mesad and a larger more curved 
spine dorsad. Caudal metatarsus longer than combined length 
of succec'ding joints. 
'rh<‘ ty])(‘ of P(H/<>iio(ia.sl('r tristani Roliii shows oiu' of these spines on one 
of the ee])liiilie til)iiie, the ottier laekiiifr armament in this area. Tliat indi- 
vidual may prove to ho a specimen ahnormal in this respect.
