198 DOLICHOPIDiE. 



The female has short antennae, with the third joint ovate, the long 

 ai'ista placed a little before its tip ; the wings broader than in the 

 male ; the femora and tibiae yellow, only the tip of the hind femora a 

 little darker, the tarsi dusky, with the metatarsus yellowisli except at 

 the tip. 



Commou in swampy spots. (E. S. I.)

The description of the preceding apphes to this also^, so exactly, 

 that it is necessary only to mention the differences. The ajipen- 

 dages are longer, the outer ones ticice as long as the hypopygmm, 

 strap-shaped, obtuse, pubescent, dingy yellow, but appearing black- 

 ish at the base, where they are apphed to the inner ones, tvhich 

 end in a long, pale, compressed, slightly curved thread, ciliated at 

 the tip. The females of the two species are scarcely distinguishable. 



In the like situations with the last, and equally common.

Metallic blacldsh-green. Front steel-blue. Face silvery-white. An- 

 tenncB not as long as the thorax, third joint about three times as long as 

 the arista. Scutellum bluish. Wings brownish. Inner appendages 

 short, dilated at the tip, but thinly ciliated on the lower edge ; outer 

 ones elongated, dilated in an angle near the base, after this attenuated, 

 linear, ending in a single long hair. Legs yellow ; posterior coxa grey 

 outside, and each with a single black bristle, the fore pair without any ; 

 in the hind pair the upper edge of the femora towards the tip, with the 

 tibiae and tarsi, blackish-brown, the tibia3 often lighter ; the anterior 

 tarsi dusky towards the tip ; the fore metatarsns a little curved and 

 fringed above with longer pubescence ; the spines of the tibia3 rather 

 stronger than in the preceding two species. The female probably may 

 be best distinguished from them by the fewer black bristles on 

 the coxae. 



Not uncommon. (E. S. I.)
