one-third longer then wide when viewed from above. When seen from 

 the side it is nearly triangular, with the face very strongly reflexed. 

 Vertex and front above antennce smooth and highly polished. Face 

 long, gradually narrowed below, its surface faintly punctulate. Eyes 

 small, round, bare ; separated from the posterior margin of the head 

 by more than their own diameter. Ocelli in a triangle, the median one 

 farther anterior to the lateral ones than the distance separating these 

 from each other. Mandibles and palpi ferruginous. Antennas 13- 

 jointed, as long as the head and thorax, and much thickened. Scape 

 stout, about two and one-half times as long as thick; pedicel minute; 

 first and second flagellar joints of equal length, about twice as long 

 as thick, and each three-fourths as long as the scape ; following joints 

 growing shorter, after the sixth quadrate, the last longer, acute at the 

 tip ; in color they are ferruginous at the base, shading into black near 

 the middle of the flagellum. Thorax unusually narrow, metanotum 

 and scutellum smooth, polished ; the latter with a depression across 

 the base, and more strongly elevated medially than is usual. Metano- 

 tum slightly longer than high, rather abruptly declivous behind ; its 

 surface finely rugose, above with a faint median carina, not extend- 

 ing on to the posterior slope, surrounded by a more nearly smooth 

 area. Pro- and mesopleurae polished, smooth ; tegulse testaceous. Ab- 

 domen shining black ; petiole rugose, broader then long ; second seg- 

 ment striate only at the extreme base. Cauda short, scarcely longer 

 than the hind metatarsus, with an unusually slender, acute tip. Legs 

 yellowish brown ; hind coxae black ; inner spur of hind tibia one-third 

 the length of the metatarsus. Wings hyaline, with no indications of 

 discoidal veins ; stigma piceous ; marginal cell one-half as long as the 

 stigma ; radial vein fuscous. 



Described from one female specimen collected on the slope of 

 Mount Constitution on Orcas Island, San Juan Co., Wash. 



The head is more elongate in this species than in any other 

 member of the genus which I know. It approaches most closely 

 to two Canadian species described by Ashmead, longiceps and 

 canadensis, but can be readily recognized by the shorter antennal 

 joints, longer head, and different metathoracic characters.
