so thick dorso-ventrally as wide; pronotum strongly arcuate; mesoseutum 
much longer medially than at the sides and somewhat less than twice as 
wide as long, its posterior margin nearly transverse or only slightly pro- 
duced medially; axillae over twice as wide as long and very acute medi- 
ally, their inner tips slightly separated or covered by the mesoseutum; 
scutellum nearly as long as the scutum, the greatest width about equal to 
the length, the width decreasing from near the base to the rounded apex, 
the sides low yet abruptly declivous, the disk moderately convex; propo- 
deum extremely short in the middle, but strongly lengthening and becom- 
ing declivous towards the sides. 
Abdomen a little shorter than the thorax, triangular in outline, with 
the basal angles rounded and strongly depressed with the dorsum a little 
sunken in; vibrissal plates situated on the lateral margin a little before 
the middle; ovipositor sheaths barely protruded, the spicula (in the unique 
type) les free from the sheaths and curves downward and a little for- 
ward from the point where it issues a short distance from the apex of the 
venter. 
Legs rather short, the middle tarsi considerably stouter than the hind 
tarsi, but not distinctly tapering towards apex, the basal joint about equal 
to the spur of the middle tibiae and about equal to the following three 
joints combined. Wings as in abilis, as figured by Silvestri except in the 
following particulars: Marginal vein fully twice as long as wide, the stig- 
mal practically equal to the marginal in length and much more expanded at 
apex and constricted at base than in abilis, the post-marginal about one-half 
as long as the marginal; the row of about seven coarse setae guarding the 
proximal side of the speculum extends more than three-fourths of the dis- 
tance towards the opposite margin; the second row of finer setae situated 
just proximad extends for the same distance as the first row and parallel 
with it, and there is another row of setae lying beneath and parallel with 
the submarginal vein; the discal pubescence beyond the speculum is moder- 
ately dense and fine, and the marginal fringe is extremely short, but dense. 
Head with very fine reticulations transversely arranged between the an- 
terior corners of the eyes and just above the facial impression arranged 
in lines conforming to the rounded margin of the impression, and in this 
manner extending downward and forward on the face towards the cheeks; 
the dorsal and anterior orbits of the eyes with a row of pin-punctures, 
which become gradually smaller and obscurer anteriorly; frontovertex pro- 
vided also with two other curved rows of pin-punctures, beginning close to 
the orbital row on each side near the anterior part of the frons and eury- 
ing backward to join together in a loop behind the anterior ocellus. Mesos- 
eutum with equally fine scaly reticulations producing a somewhat rougher 
effeet than on the head and with numerous seriately arranged minute 
setiferous punctures; axillae appearing smoothish, yet with an extremely 
fine reticulation, the scutellum smooth and highly polished; propodeum 
smooth except for a small longitudinally shagreened median area, and pro- 
vided with a distinct median carina, the posterior margin also ecarinate,
