ished black rounded protuberances; length before pupation 10 mm.; usu- 

 ally from three to a dozen or more larvae occupy an infested pitcher. 



Pupa. — Suspended among or imbedded in froth-like white filaments; 

 often several pupae in close proximity in a common froth-mass which is 

 denser about each pupa, thus approximating a frail cocoon-like structure, 

 from which the pupa pushes its way before emergence of the fly; pupa 

 yellowish white, soon darkening, especially the eyes, with the pigmenta- 

 tion of the imago; base of antennae prominently arched over the eyes, but 

 not in contact medially; abdominal spiracles marked by minute concol- 

 orous pointed projections; length about 4 mm. 



Imago, cf and 9 .—Length 3 to (9) 3.8 mm., dry; liv'e females often 

 slightly exceed 4.5 mm.; fuscous black to black; head and thorax denser 

 in color than the abdomen, somewhat polished, finely punctate, hairs 

 black. Eyes black, finely pubescent, their finger-shaped frontal projec- 

 tions failing of contact by less than width between antennae; lateral ocelli 

 remote from eye-margins, inclined on a rather prominent ocellar protuber- 

 ance. Palpi and antennae smoky; intermediate joints of the ilagellum 

 twice as long as wide, last flagellar joint elongated; antennae of 9 about 

 one-sixth shorter than those of the (f. 



Halteres slender, finely pubescent, smoky, the stems pale; coxae and 

 femora brownish-yellow, with dark hairs; tibae darker, more smoky, and 

 tarsi almost black; trochanters dark beneath; length of hind tibia to 

 tarsus, as 100 to 85. 



Wings brownish-hyaline; costa, radius, and R-M cv. setose; cubitus 

 and media not setose, except that basal section of media of ^f usually 

 bears one or two setae; costa produced fully two-thirds of way from Rs to 

 Ml; Rs and M2 end about equidistant from the base of the wing; the 

 base of Rs is slightly distad of the mid-point between the humeral cross- 

 vein and the tip of Ri; subcosta very faint, ends free, proximad of the 

 origin of Rs; Ri ends slightly' proximad base of fork of M (in measured 

 wings, from one-twenty-sixth to one-tenth of the wing-length proximad); 

 petiole of cubitus about same length as basal section of media. 



Abdomen black-haired; lateral band (in fresh examples) yellowish 

 brown; the distended body of the 9 dries to an almost uniform smoky 

 brown, paler than that of the cf ; hypopygium dark, claspers subglobose, 

 shortly stemmed to and more than half as long as the preceding joint and 

 with no mesal processes or differentiated apical spines: lamellae of 9 ovi- 

 positor about one and one-third times as long as broad.
