Acanthojoppa major sp. nov. 
Female.—Length, 16 millimeters; antenne, 13. Head sub- 
opaque punctate; temples convexly sloping, not nearly as wide as 
eyes; frons deeply concave with a slight median elevation, the 
antennal scrobes highly polished below; vertex medially dis- 
tinctly below level of top of eyes, strongly sloping behind to oc- 
cipital carina; occiput moderately concave; eyes large, bulging, 
divergent below, hardly longer than their distance apart below; 
face nearly fiat, rather densely punctate, with a ridge on each 
side on the inner orbit, which extends obsoletely to the lateral 
angle of the clypeus, bordered dorsally by a curved ridge that 
unites at each side with the orbital ridge and extends dorsally as 
a fine carina nearly to top of eye; clypeus nearly flat, slightly 
elevated at base medially, at apex broadly rounded with a very 
inconspicuous median truncature, punctate at base, polished at 
apex ; labrum subangulately rounded at apex; malar space as long 
as basal width of mandible; cheeks in front view nearly straight; 
Scape distinctly elongate, flagellum rather stout, its basal joint 
little more than three times as long as thick at apex. Thorax 
densely punctate, the mesoscutum and scutellum very finely punc- 
tate, the pleura coarsely subrugulosely so; notauli obsoletely 
impressed to middle of mesoscutum; scutellum pyramidal, sinu- 
ately tapering toward summit, which is deeply emarginate, its 
sides densely punctate; propodeum rugose-punctate, basal areas 
polished, spiracular area open behind, apical transverse carina 
largely obliterated by coarse sculpture, areola nearly a regular 
hexagon, open behind, apophyses long and stout and situated dis- 
tinctly behind middle; legs slender, hind femur reaching nearly 
to apex of abdomen; longer hind calcarium reaching distinctly 
beyond middle of basitarsus; basal vein curved; nervulus post- 
furcal; radius originating at middle of stigma; areolet very 
narrowly sessile, practically quadrilateral; first brachial cell 
short and much wider at apex than at base, the basal abscisse 
of discoideus and brachius being strongly divergent and the sec- 
ond and third abscisse of discoideus combined nearly as 
long as first; intercubitella little more than a third as long as 
basal abscissa of radiella. Abdomen minutely punctate, opaque ; 
petiole distinctly compressed; postpetiole polished, four times 
as wide at apex as petiole, sides beyond spiracles divergent; 
Second tergite wider at apex than long, gastroceeli distinct, 
rather broad, shallow. The area cephalad of each one longi- 
tudinally striate; third tergite nearly twice as wide at base as 
long; ovipositor strongly exserted.
