cT Length 7-8 mm. Dark reddish brown, varied with lighter 
brown, the paler markings, not very sharply defined, as follows: 
head below the antennae, entire orbits, vertex, neck behind, 
irregular streaks on mesonotum, margin of propleura, mesopleura 
except behind, propodeum except for a median dark line, lateral 
spot at middle of first and at tip of first, of second and of third 
abdominal segments, posterior margin of following segments, 
base of antennal scape and four anterior tibiae; hind legs with the 
femora and tibiae lighter on the lateral surfaces. Wings hyaline, 
stigma and veins piceous. hlead distinctly wider than the thorax, 
one-half broader than thick, occipital margin sharp, but not 
strongly elevated; ocelli in a triangle, as far from one another as 
from the eye-margin. Eyes with their facial margins parallel, 
surface sparsely but distinctly hairy; almost touching the base of 
the mandibles. Occiput irregularly, transversely aciculate, the 
striae oblique to the side of the ocelli and very fine and more or less 
concentric about the base of the antennae; clypeus and face below 
antennae smooth, except for very delicate dense punctures at the 
sides just below the antennae. Mandibles large, the basal and the 
apical tooth long. Antennae inserted just above the middle of the 
eye: scape and first flagellar joint about equal, each two and one 
half times as long as the pedicel; second and third flagellar joints 
equal, together barely one-third longer than the first, each nearly 
twice as long as thick; following gradually decreasing in length, 
the penultimate but little longer than thick. Head behind the 
eyes smooth, the foraminal margin higher than on the occiput, 
transparent. Neck barely as long as the distance from tegula 1o 
anterior margin of mesonotum, with a very strong median 
carina below. Mesonotum with a V-shaped impression formed by 
the parapsidal furrows which originate on the sides at the 
anterior third and meet medially behind at the posteiioi thiid, 
between them near the anterior margin are traces of two delicate 
impressed longitudinal lines; surface coarsely transversely striate,
