teniifE brown-black, the three or four basal joints pale or yellowish, especially 

 beneath. Legs honey-yellow, the tarsi faintly dusky. Abdomen rufo-piceous or 

 ferruginous, varying somewhat in depth of coloring. Head and thorax smooth, 

 polished : face below antennae faintly punctate ; metathorax rugulose, with only 

 a trace of a long central area; antennse long and slender, much longer than the 

 body, tapering toward tips, 30-jointed, the first flagellar joint the longest, the 

 others shorter and slightly gibbous at the middle, giving them a cord-like ap- 

 pearance; thorax with two furrows that converge and meet before thescutellum, 

 the middle lobe with a delicate grooved line on its basal half; scutelluni smooth, 

 with a large crenate fovea at base; metathorax rugulose, with medial earinse. 

 Wings hyaline, the stigma and venation light brown, the recurrent nervure 

 joining an angle in the second submarginal cell, the fii'st abscissa of radius about 

 as long as the second. Abdomen long-oval, shining, but with the surface finely, 

 minutely wrinkled, the second segment very much longer than any of the others, 

 about as long as the third, fourth and fifth united, with an oblique grooved line 

 at each basal angle.

Type in coll. Ashmead. 



The single specimen in my possession was kindly given me by my 

 friend, Mr. E. A. Schwarz, who captured it Aug. 23, 1890. 



At first sight I was inclined to believe this species the opposite sex 

 of H. erythrog aster, also captured at Cedar Point, but its much 

 smaller size, different colored legs, sculpture of metathorax and the 

 ])aucity of joints in antennae readily separate it. 



4. H. atriceps sp. n. 



% 9 • — Length 1.6 — 1.8 mm. Head, except clypeus and mandibles, black ; rest

 18 — 19-joiuted, longer than the body, the first flagellar joint the longest, the fol- 

 lowing joints from three to three and a half times as long as thick; thorax 

 smooth, polished, with delicate parapsidal furrows, the metathorax feebly punc- 

 tate, areolated, the central carina quite distinct. Wings grayish hyaline, the
