COLOMBIAN DERMAPTER\ AND ORTHOPTERA 
Tet^aiina delicate, with (seven sinistral, six dextral) longitudinal discoidal 
sectors, cross-veinlets decided and strikingly colored distad and in area of 
dextral tegnien concealed when at rest. Wings delicate, proximal (seven) 
costal veins heavily clubbed distad, this ami the coloration of this area as 
described for albida, ulnar vein with (five) complete branches, intercalated 
triangle small. Abdomen with dorsal surface unspecialized, except that the 
sixth tergite bears mesad a few scattered, microscopic hairs. 
Sui)ra-anal plate transverse, with free margins straight and nearly trans- 
verse, weakly oblique to less than median third, where the plate is i)roduced 
in a moderately deflexed area, twice as wide as long, with brief lateral mar- 
gins straight but rounding without angulation into the broadly convex cau- 
dal margin. Paired plates beneath supra-anal plate unspecialized. Cerci 
elongate and slender. Subgenital plate with sinistral portion straight, curled 
briefly upward, its margin straight, oblique, at the apex of the channel thus 
formed is situated an elongate, slender, flattened jn'oeess (probably the 
sinistral .style), over three times as long as its basal width, directed in the 
same line and consequently meso-distad, tapering from fts j^roximal quarter 
to the sharply rounded apex and decurved in distal fourth. Adjacent to 
this dextrad is a similar ])rocess (probably the dextral style), si)ringing from 
an almost obliterated socket, slightly more elongate, bearing in the same 
direction proximad but curving sinistrad in the distal portion, so that the 
apex is above but beyond that of the sinistral jjrocess, these two i)rocesses 
have their dorsal surfaces proximad armed with rather closelj^ placed, erect, 
microsco])ic, conical teeth. Adjacent to these processes dextrad is a third, 
very slender j)rocess, slightly the shortest of the three, cylindrical but some- 
what irregular in contour, unarmed, straight and directed more strongly 
dextrad than the others. From this process the free margin of the plate is 
feebly concave, moderately oblique to the dextral section of the j)late. Dex- 
tral section of subgenital i)late with lateral margin straight to beyond cereal 
base, in this j)ortion shar])ly folding inward at the margin ami forming a 
lamellation with dorsal surface very strongly concave, thus embracing the 
l)roximal portion of the dextral style. So com])lex is the subgenital plate 
that reference to plate VllI, figure 8, is recommended. 
Limbs and armament as in accuithastyldhd'^ (except that the flange of tlie 
tarsal claws is armed with seven teeth, though the three more distal ones 
are the more conspicuous). 
flcneral coloration huffy, tinged with tawny olive. Head of this coloration 
with four tran.sver.se suffust'd bands of darker brown, the heaviest between 
the ventral margins of the eyes, the next between the dorsal margins of the 
ocellar .s])ots, the next between the ventral margins of the ocellar spots and 
the last very weakly indicated above thc^ clypeus, the three last broken mesad. 
Pronotum with disk ochraceous-buff, j)ictured with delicate lines, and a 
blotch later-caudad on each side, of (dnnamon brown and dots of deep mars 
brown; marginal i)ortions hyaline with a faint butfy tinge. Tegmina and 
wings hyaline, cro.ss-veinlets of tegmina distad heavily suffused with ])rout’s 
brown; veins, spuriovis veins and cro.ss-veinlets in area of dextral tegmen,
