COLOMBIAN DERMAPTEK\ AND ORTHOPTER.\ 
Type. — cf ; Mainatoco/® ^Magdalena, Colombia. Elevation, 50 
feet. Decemlier, 1917. (INI. A. Carriker, Jr.) [Hebard Collec- 
tion, J^pe no. 538.] 
In addition to the generic features already given, we would note the follow- 
ing for the iwesent species. Interocidar si)ace four-fifths that between the 
antennal sockets. Inter-ocular-ocellar area flattened. Ocellar sjjots large, 
their areas showing no defining contour. Lateral margins of cheeks weakly 
convergent ventrad. Maxillar}" palpi missing. Tegmina with numerous 
discoidal sectors (twelve to thirteen). Wings with (eight to ten, the varia- 
tion caused by distal branching) complete branches of the ulnar vein. Fifth 
tergite with broad median section shallowly concave; sixth with broad 
median section slightly more deeply concave, with a slightly raised medio- 
longitudinal V-shaped area, its lateral margins slightly convex and thickly 
supplied with agglutinated hairs directed caudad, the caiulal margin subchi- 
tinous and weakly and broadly emarginate mesad; seventh and eighth ter- 
gites transversely narrower, exposed very narrowlj^ along their caudal margins. 
Supra-anal plate triangular with ajiex broadlj' rounded, its length two-fifths 
its basal width. Cerci slender and elongate, tapering to acute apex, the 
joints (thirteen in allotype, damaged in type) well defined, the lateral margin 
of each nearly straight, the dorsal surface weakly convex, the ventral surface 
decidedly convex between the narrowly lamellate lateral margins. Paired 
plate beneath supra-anal plate large and unspecialized. Titillator with 
chitinous distal portion short and heavy, terminating in a sharp decurved 
])oint. Subgenital plate with proximal ])ortion very weakly convex, latero- 
distal portions slanting sharply upward, their dorsal margins weakly sinuous, 
transverse to the styles. The latter are rejiresented by lamellate plates, 
moderately convex externally, broadly hinged to the lateral portions of the 
subgenital jdate, vertical and directed caudad, slightly dee]3er than long, 
with free margins convex, particularly distad. The brief median portion 
of the free margin of the subgenital plate between these is triangularly ju'o- 
duced dorsad, its tlistal portion slender, slightl}’ thickened and curv'ed cau- 
dad, with a])cx sharp but unarmed, this portion with height ecpial to its 
basal width. 
Caudal metatarsus sup])lied with a large rounded distal pulvillus, succeed- 
ing three joints with ventral surfaces fvdly occupiefl l)y large pulvilli (from 
immature example, caudal metatarsi missing in tyi)e and allotype). 
Allotype . — 9 ; same data as type. [Hebard C'ollection.] 
.\grces fully with male in most ambisexual features, differing in the follow- 
ing resi)ects. Size Larger; tegmina and wings fully developed in similar 
projxu'tion. Interocular sjjace very slightly wider. Inter-ocidar-ocellar 
area slightly less decidedly flattened. Dorsal surface of abdomen unspecial- 
ized. Supra-anal i)late one-third as long as basal width, triangular but 
bilobate at aj)ex, this due to a short medio-longitudinal distal cleft, which 
'** 1 his hxaihty is four and one-half miles from Santa Marfa, in the arid 
coastal region.
