oval or fusiform area on the posterior margin at base of wing; an 

 oval spot at the constricted part of the disk extending obliquely 

 basad from the submarginal vein not quite to the opposite margin; 

 a narrow arcuate crossband with the concave side distad, situated 

 just beyond the middle of the wing at the base of the widest part 

 of the disk and just touching apices of the postmarginal and stigmal 

 veins; and a narrow band at apical margin of the disk. Submar- 

 ginal vein reaching almost to the middle of the wing, strongly 

 sinuate or curved inward at the constricted region of wing; mar- 

 ginal and postmarginal veins equal, very thick and widest at their 

 juncture, each fully four times as long as wide; stigmal vein form- 

 ing a right angle with the postmarginal, about three-fourths as long 

 and enlarged at apex, its apical margin very broadly emaginate, the 

 four postules arranged in a curved line. Speculum very oblique, ly- 

 ing almost parallel with the marginal vein and apex of the submar- 

 ginal and passing into the clear oval area at the constricted part of 

 the disk, beyond this area continued and connecting with the basal 

 clear area. Costal cell narrow except w^here the submarginal vein 

 curves inward, mostly hyaline and bare excepting a row of setae on 

 the basal third, and a marginal row of setae on the apical third. 

 Setae on the veins very numerous but small, about equaling in size 

 those between the speculum and the marginal vein, which are dis- 

 tinctly but not greatly larger than the remaining discal setae. 



Head with very fine roundish reticulations and with numerous 

 minute pin punctures on the frons, which become finer and closer 

 toward the antennal sockets and much sparser toward the vertex, 

 there being practically no punctures on the vertex behind the ocolli; 

 mesoscutum finely reticulate, axillae and scutellum finely longi- 

 tudinally punctato-reticulate and duller than the scutum ; mesopleura 

 microscopically reticulately shagreen: d, but much more coarsely 

 so on the posterior margin; abdomen very finely reticulate. 



Sides of head behind the eyes, the face, checks, pronotum, 

 mesoscutum, propodeum, abdomen, and legs provided with numerous 

 appressed fine white s^tae, which are distinctly longer behind the 

 eyes and on the propodeum; scutellum with very spai'ce, fine, incon- 

 spicuous setae and two rather long bristles at apex; frontovertex 

 almost bare, the very few fine setae present being very inconspicuous ; 

 eyes with sparse, very short, erect setae. 



Coloration metallic but not brilliant, the surface of body being 

 moderately and not uniformly shiny. 



Male. — Not known.
