tate, with no suture between it and the face; antenn?e forty-seven jointed, scape 

 and pedicellum together about as long as the first joint of the flagellum. Thorax 

 shining, sculptured irregularly like the head, but the punctures stronger on the 

 pleura, the pleura also partly smooth and practically impunctate; parapsidal 

 grooves of mesonotum deeply impressed and converging posteriorly, terminating 

 in a semilunar depression which is rugose; metanotum rugulose, not areolated, 

 some ridges or raised lines present; wings slightly darkened, transverpe median 

 nervure nearly interstitial with the basal nervure, a little basad of the transverse 

 median nervure, first discoidal cell sessile, second abcissa of the cubitus as long 

 as the first abcissa of the radius, a little shorter than the second transverse cu- 

 bitus; the second abcissa of the radius as long as the first transverse cubitus. 

 Spurs of posterior tibia? thickened, not tapering, shaped like a talon. First ab- 

 dominal segment smooth, shining, with shallow small impressions, with a lateral 

 carina that is nearly straight ; the remaining abdominal segments more dullish, 

 somewhat punctured. Thinly pubescent with white pubescence. Testaceous, 

 in part with a castaneous tint; between the ocelli the tegument is nearly black; 

 claws very dark brown ; flagellum and tarsi more or lees brownish; nervures of 

 the wing brown, stigma testaceous; abdomen beyond the first segment brownish 

 except on the apical margin.

Related to M. communis and M. hyphantrite, from which it differs in size and 

 sculpture. 



Male. — Length, 4.5 mm. Head, face dullish, with closely arranged indistinct 

 minute punctures; clypeus prominent, decidedly convex, sculptured nearly like 

 the face; malar space practically wanting; front, vertex, occiput and cheeks 

 shining, minutely sculptured; scape about as long as the first joint of the flagel- 

 lum, pedicellum globular, first joint of the flagellum distinctly a little longer 

 than the second, the second and succeeding joints subequal; antennte twenty- 

 three jointed. Thorax shining; prothorax with smooth borders and a large, 

 triangular impressed rugulose space on the pleura; dorsulum very closely punc- 

 turred, the punctures small and indistinct, posterior half of the dorsulum nearly 

 entirely taken up by a semilunar rugulose impressed space; mesopleura 

 polished, minutely punctured, with a shallow, oblique groove that is partly 

 rugulose and a rugulose impression beneath the insertion of the wings; scutel- 

 lum polished, rather sparsely punctuted; metanotum rugose, almost reticulate, 

 the superior face bounded posteriorly by a sharp curved ridge, posterior face 

 nearly as coarsely sculptured as the superior face, broadly impressed along the 

 middle line longitudinally; metapleura polished, more or less closely sculptured; 

 wings clear with a brownish tint, stigma testaceous, nervures brown; recurrent 

 nervure received by the second submarginal cell distinctly beyond the first trans- 

 verse cubitus, the second abcissa of the cubitus nearly as long as the first abcissa 

 of the radius; the transverse median nervure nearly as long as the first joint of 

 the flagellum, the first abcissa of the discoidal nervure nearly as long as the 

 transverse median nervure. Abdomen shining and polished ; the first abdominal
