collected by C. R. Jones and labeled “Acc. No. 752, Bur. Agr., 
P. I.” All agree so well with Bingham’s description that there 
can be little doubt of the correctness of the determination. 
Slight variations exist in the height of the scutellar carine and — 
the strength of the sculpture. 
This species differs from the three preceding species in having 
the face and pleura striate rather than punctate, the striz on 
the face being arcuate and those on the pleura oblique; the 
clypeus strongly elevated at base and distinctly separated; the 
malar space much shorter than the basal width of the mandibles; 
the scutellum convex but not emarginate at the summit; the ner- 
vulus interstitial; and in its much smaller size. From the two 
following species it differs in the convex scutellum; strong pro- 
podeal apophyses; distinctly sculptured and subopaque face, 
pleura, and propodeum; contrastingly colored head; separated 
clypeus; and almost petiolate areolet. 
Acanthojoppa polita sp. nov. 
This and the following species differ from all those described 
above in having the propodeal apophyses obsolete and the pleura 
and propodeum polished. 
Female.—Length, 14 millimeters; antenne,11. Head polished 
throughout except that face is medially arcuately striate above; 
clypeus polished, strongly elevated at base, the elevation contin- 
uous with the median elevation of the face, foveze very deep, 
apex broadly rounded, medially subtruncate; labrum exserted; 
malar space much shorter than basal width of mandible; cheeks 
in front view straight; vertex impressed below top of eyes, 
sharply declivous behind; occiput rather deeply concave; eyes 
large and prominent. Mesoscutum and scutellum opaque; thorax 
otherwise polished, practically without sculpture, although the 
propodeum is obsoletely transversely rugulose; notauli sharply 
defined to middle of mesoscutum; scutellum flat above, the ca- 
rine becoming gradually weaker toward apex, which is subtrun- 
cate; lower portion of metapleurum separated off by a sharp 
arcuate carina between middle and hind coxe (in the four pre- 
ceding species this carina is visible only anteriorly) ; median 
areas of propodeum narrow, the areola much longer than wide, 
long horseshoe-shaped and far removed from base of propodeum, 
lateral abscisse of apical carina far behind middle abscissa; 
areolet rather broadly sessile; nervulus antefurcal; first brachial 
cell nearly parallel-sided and about twice as long as wide. Ab- 
domen opaque, narrow; first tergite stout, polished, petiole nearly
