Head smooth, more or less polished, with oiilj' a few punctures; ocelli very 
large and i)rominent, with a transverse impression behind but no imjiression 
between them, their measurements: .38 mm., .23 mm., .4.5 mm.; an ol)lique 
Carina on each side of the forehead, limiting an impressed basin above each 
antenna, the carinae originating close above the antennae, close to the eye, and 
converging upward; between these two basins the surface iirominent and 
slightly rugose; inferior margin of each antennal socket not thickened, but 
with a slight tubercle below; margin of the ch'peus prominent, medially with 
a broad in-ocess projecting downward, on either side of which the margin is 
deeply notched; mandible with the two inner teeth of equal size, unusually 
acute, the only remnant of a carina being a short tubercle at some distance 
from the inner tooth; gular orifice moderately broad, its margin produced 
into a tooth at the side, distant from the ej^es by more than the length of the 
last segment of the labial })alpus, from the swelling at the condyle of the 
mandibles bj' slightly more than the thickness of the same. Antennae some- 
what crenulate toward tlieir tips. 
Humeral angles quite noticeable but not very prominent; sides of the pro- 
notum coarsely and closely punctured, more sparsely below, the dorsal surface 
Avith only minute punctures e.xcept along the posterior margin; mesonotum 
coarsel}' but sparsely punctured, bearing strong lateral grooves; scutellum 
with a longitudinal impressed line and coarse punctures on the disc, its sides 
and the postscutellum closely and minutely punctulate; mesopleura Avith 
coarse but mostly sparse punctures, A’^ery irregularly and rugosely SAVollen, a 
large impressed basin on the most SAvollen part of each, bordered posteriorly 
by a curved carina and aboA'e by a marked rugosity; dorsal surface of the pro- 
podeiun shagreened, with a broad parallel-sided, deep, median channel, 
traA’ersed by four cross-bars; at its apex an equally broad and deep, sinuous, 
transA^erse channel, the posterior border of Avhich is formed by a carina sepa- 
rating the dorsal from the almost A'^ertical, flat, caudal surface; coarse punc- 
tures, becoming in places rugpse, are borne on the upper part of the lateral 
and caudal faces. 
Wing A-enation as shoAA-n in figure 11. 
Inner surface of the anterior tibia with a transA’erse subapical row of three 
spines; inner surface of the anterior metatarsus Avith three prominent spines; 
outer surface of the middle tibia spinose, almost to the base, and AA'ith four 
coarse sjjines near the apex of the posterior edge; posterior tibia Avith five or 
six spines along the posterior edge. 
First abdominal segment short, rather broad and thick, enlarging almost 
from the A'ery base, AA’ith only a very short anterior neck; as seen from aboA'e 
noticeably constricted from the Avide second segment; basal third of the 
second ventral segment with a strong raised longitudinal keel, ending in a 
sharj) tooth posteriorly; first segment laterally, closely and coarsely punctured, 
dorsally Avith sparse i)unctures, remaining segments polished, Avith only sparse, 
minute, setigerous jnmeturos; pygidium truncate, with AA’eak lateral carinae, 
n,nd coarse punctures toAvard the sides at ba.se.
