elongate pale markings, wing apex and two diagonal markings extending 
from it anterolaterally to intersect costal margin, black; a transverse slightly 
oblique red marking extending to clavus in apical one-fifth of forewing; face, 
venter, thoracic pleura, and legs as in D. euthemis, n. sp. 
Holotype male, two additional males, two females, and one specimen 
without abdomen, ‘“‘Sinchono”’ Peru (D. M. DeLong collection, OSU). Six 
specimens of both sexes. Tingo Maria and 10 mi. SW of Las Palmas, 
Hudnuco Prov., Peru (CAS). 
D. erupa, n. sp., is closely related to vartegata (Fabricius), from which it may 
be separated by the characters in the key and in the above description. It 
should be noted that the lack of an angle at the ventral portion of the 
aedeagal apex is not a good specific character in this genus, but the shape of 
the male pygofer, which differs from variegata, is very constant in the 
specimens studied thus far. 
51. Genus PACHITEA MELICHAR 
FicuRES 266-269 
Pachitea Melichar, 1926a: 344. Type-species: Tettigoniella habenula Jacobi, by subsequent 
designation of China, 1938d: 184. 
Length 8.0-10.7 mm. 
Head well produced, with median length of crown usually varying from 
eight-tenths of to almost one-fifth greater than interocular width and from 
one-half to slightly more than eight-tenths transocular width, anterior margin 
moderately rounded in dorsal view, with a carina at transition from crown to 
face at apex, ocelli located behind a line between anterior eye angles, each 
closer to median line than to adjacent anterior eye angle, crown concave, 
without a median longitudinal fovea, with oblique striae parallel to margins of 
antennal ledges, lateral clypeal sutures extending onto crown and attaining 
ocelli; antennal ledges not protuberant, in lateral view with anterior margins 
strongly oblique and convex; clypeus convex, not tumid, muscle impressions 
distinct or not, face without pubescence, transclypeal suture usually in- 
complete, clypellus not produced, its contour continuing profile of clypeus. 
Thorax with pronotal width varying (interspecifically) from less than to 
greater than transocular width of head, lateral margins convergent anteriorly, 
dorsopleural carinae complete, posterior margin concave, disk without trans- 
verse rugae, not pubescent; scutellum not rugose behind transverse sulcus. 
Forewing without a distinct membrane, with apical portion less opaque than 
remainder, but not abruptly delimited, veins not very distinct, with four apical 
cells and with base of fourth more proximal than base of third, without an 
anteapical plexus of veins, outer anteapical cell not spindle-shaped, reaching 
third apical cell, texture coriaceous except apically, without sculpturing; 
apical margin oblique to slightly concave; forewings of female in rest position 
exceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1, length 
of first tarsomere much greater than combined length of two more distal tar- 
someres and with two parallel rows of small setae on plantar surface.
