verse, twice as broad as long. Vertex and front shining, impunctate; 

 between the antennae with a median raised line which extends almost 

 to the clypeus. Face faintly punctulate with a longitudinal depres- 

 sion on each side of the median elevation. Eyes oval, bare, broader 

 than the temples. Ocelli in a triangle which is much broader than high. 

 Mandibles and palpi fuscous. Cheeks impunctate. Antennae 13-jointed, 

 considerably longer than the head and thorax together; stout, en- 

 tirely black, joints 2-8 of flagellum each with a tooth-like projection at 

 the middle of the upper side. Scape stout, twice as long as thick, pedicel 

 minute ; first flagellar joint about four times as long as thick, not 

 dentate or toothed ; second and each following joint somewhat shorter, 

 but very slightly so, and gradually more slender ; last joint very little 

 longer than the penultimate, very slender with acute apex. Mesonotum 

 shining slightly fuscous pubescent like the head. Scutellum broad, 

 evenly convex, with a transverse depression at the base. Metathorax 

 nearly twice as long as high ; angulate, not curved at the upper edge 

 of the posterior slope when seen in profile ; its surface entirely coarsely 

 rugose-reticulate, except above where a large shield-shaped much 

 smoother area is formed by two lateral carinae which meet behind. 

 This area is divided by the usual median carina which however does 

 not continue on the posterior slope. Pro and mesopleurae smooth ; pol- 

 ished ; tegulae ferruginous. Abdomen as long as the head and thorax ; pet- 

 iole as long as broad, coarsely fluted ; second segment with a few coarse 

 deep striae at the base ; apical spines black. Legs bright ferruginous 

 except the bases of the coxae which are black, especially on the posterior 

 pair. Femora slender, inner spur of posterior tibia not quite one- 

 half as long as the metatarsus ; all tarsal claws simple. Wings quite 

 distinctly infuscated, with the discoidal veins very distinctly indicated 

 by brownish streaks ; stigma, except upper half, and radial vein very 

 dark fuscous; marginal cell petiolated, less than one half as long as 

 the stigma. 



Described from a male collected on Mount Constitution, Orcas 

 Island, San Juan Co., Wash., July 31, 1908 (A. L. Melander). 



Allied to calif ornicus Holm, but separable from this and other 

 species with dentate flagellar joints by the large divided shield- 

 shaped area on the metathorax. 



Proctotrypes obscuripes sp. nov. 



Male. Length 4 mm. Entirely black, with the base and tips of 

 the femora and part of the tibiae and tarsi honey-yellow. Head trans-
