middle; subgenital plate rather broadly ligulate, slightly decurved, 

 and with scattered erect hairs that are a little longer than the width 

 of the plate, straight, and with their apical 0.25 bent over. 



Black. Wings hyaline, margined apically with light fuscous; 

 seventh tergite with a large dirty white spot. 



Female: Forewing 5.0 to 6.5 mm. long; apical hairless margin of 

 clypeus a little widened medially to make an indistinct median tooth ; 

 temple with about ten long suberect hairs; mesopleuron without an 

 oblique carina at the front end of its transverse groove; propodeum 

 without wrinkles. 



Black. Head, pronotum, mesonotum, and abdomen with a rather 

 weak, dark, greenish blue iridescence; wings subhyalme, the apical 

 0.35 of the forewing somewhat infuscate and the apical part of the 

 hind wing weakly infuscate. 



Specimens (30 cf , 31 9 ): From Connecticut (East Hartford) ; Dis- 

 trict of Columbia (Washington) ; Indiana (Mineral Springs) ; Kansas 

 (Onaga) ; Maryland (Cabin John and Glen Echo) ; Massachusetts 

 (Sherborn, South Natick, and Wellesley) ; New Jersey (Chatsworth in 

 Burlington County) ; New York (Enfield Glen in Tompkins County, 

 Gardiners Island, Ithaca, and Niagara FaUs) ; North Carolina (Crab- 

 tree Meadow at 3,600 ft. m Yancey County, Hamrick, and Hot 

 Springs) ; Ontario (Ridgeway) ; Pennsylvania (Mount HoUy Springs) ; 

 Quebec (Aylmer) ; and Virginia (Arlington, Falls Church, and Rosslyn). 



Dates of collection faU mostly between July 10 and Sept. 8. 

 The earlier and later dates on record are July 8 at Falls Church, Va. ; 

 July 21 at Niagara Falls, N. Y.; July 23 at Ithaca, N. Y.; July 24 at 

 Onaga, Kans., in Burlington County, N. J., and at Washington, D. C; 

 Sept. 6 at Falls Church, Va., Sept. 7 at Ridgeway, Ont., Sept. 8 at 

 Aylmer, Que., and Sept. 23 at Cabin John (near Washington, D. C), 

 Md. Seven of the collected lots are definitely recorded from woods. 

 Included in these is a collection of 11 d", 6 9 from "dense woods," 

 and a collection of 2 9 taken "on bushes in open woods," 



This is a woodland species of the Alleghenian and Carolinian faunas. 

 There seems to be a single generation a year; it emerges late in July 

 and is on the wing into early September.
