d^ Length 7-8 mm. Dark reddish brown, varied with Hghter 

 ■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 tibise; hind legs with the 

 femora and tibiae lighter on the lateral surfaces. Wings hj^aline, 

 stigma and veins piceous. Head 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 to 

 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 posterior third; 

 between them near the anterior margin are traces of two delicate 

 impressed longitudinal lines; surface coarsely transversely striate,'
