 to be the same species.

Female. — Length 4 mm. Labrum broadly rounded; clypeus rather deeply, sub- 

 angulately omarginate, lobes triangular, obtusely rounded; supraclypeal area shining, 

 somewhat convex; middle fovea small, well defined; antennal furrows interrupted 

 by the rounded frontal crest; ocellar basin shallow, well defined, rectangular in out- 

 line; postocellar area narrowing posteriorly, well defined; postocellar furrow arcuate; 

 front with sparse, small punctures; antennre rather robust, third and fourth joints 

 subequal; venation as in Plate XXVI, figure 3; upper discal cell exceeding the lower 

 on the outer margin; sheath and saw as in Plate XXIV, figiu-e 6, and Plate XXIII, 

 figure 4. Color reddish yellow; antennae beyond scape, posterior part of mesoscutum, 

 the mesoscutellum, the metanotum, and the tergum except apex black; wings hyaline, 

 iridescent; venation yellowish pallid. 



Paratopotypes show that the scape and interocellar area may be black. 



Male. — Length 3.5 mm. Sufficiently like the female to be easily associated with it. 

 In the following color characters it differs from the female: Antennpp reddish yellow, 

 interocellar area black, mesonotum black. Hyjiopygidium rounded apically to an 

 obtuse angle. 



Type locality. — Montana. Four females and two males.

Hoplocampa (Hoplocampa) halcyon (Norton). 



(Plate XXIII, flg. 8; Plate XXIV, fig. 9; Plate XXV, flg. 2; Plate XXVI, flg 2.) 



Selandria {Hoplocampa) halcyon Norton, Proc. Boston Soc. Nat. Hist., vol. 8, 

 p. 222, 1861, no. 10, $ ^ ; Norton, Trans. Amer. Ent. Soc, vol. 1, p. 252, 

 1867, no. 16, $ ? . 



In the collection of the American Entomological Society Hoplo- 

 campa {Hoplocampa) halcyon (Norton) was confused with Hoplocampa 

 ( Macgillivrayella) lacteipennis Rohwer. That which agreed with. Nor- 

 ton's original description, and was from the type locality, has been 

 considered the type. Agreeing with this type, specimens have 

 been seen from the following localities: Ithaca, N. Y. (two females); 

 Canada (one female) ; McLean, X. Y., May 8, 1891 (male and female) ; 

 Washington, D. C, April 22, 1885 (one male); Clementon, N. J., 

 April 25, 1909, Harbeck (one male which has the mesoscutum dark 

 brown). Norton records this species from Maine, Massachusetts, 

 Maryland, and Saskatchewan. 



Konow'* states that this species feeds on Amelancliier canadensis. 

 Tiie only statement which seems to indicate such a habit is by Nor- 



(^Zeitschr. syst. Hym. Dipt., vol. 1, p, 174, 1901; or Syst. Zusam. Chalastogastra, 

 p,46, 1901.
