39 ENTOMOLOGICAL NEWS. [Nov., 'l6 



found in a leaf, but even when most numerous they do not ap- 

 pear to have been laid in groups or clusters, and the maximum 

 number is attributable to the visits of more than one female to 

 the same leaf. 



Egg. Cigar-shaped, roundedly-pointed at one end, the other with a 

 short cylindrical or collar-like cap of less diameter than the body of the 

 egg ; obscurely and shallowly wrinkled longitudinally ; white, opaque, 

 pearly, faintly polished, under 100 X finely punctate; length .9 mm., and 

 greatest diameter .2 mm. 



Larva. Slender, cylindrical, tapering and strongly retractile anterior- 

 ly ; white, translucent, smooth, but segmentally with narrow ventral 

 fusiform areas marked by short acute granules, coarser beneath and 

 fading out laterally ; black cephalo-pharyngeal skeleton with two great 

 hooks visible through the translucent anterior segments ; anterior 

 spiracle inconspicuous, f ew-lobed, concolorous, not protruded ; the two. 

 posterior dorsal stigmata in form of even-armed crosses surmounting 

 prominent dome-shaped processes, the inner arm of each cross partially 

 obliterated by the circular extremities of the tracheal tubes ; anal lobes 

 low, smoothly rounded ; extreme length about 5 mm. The larvae are 

 active, moving freely about among the insect remains and climbing up 

 the vertical wall of the pitcher in search of food or when ready to 

 pupate. 



Puparium. Shorter and stouter than the larva and hardening to a 

 dull bronzy-brown color ; flattened ventrally where in contact with the 

 leaf ; segmentation not distinct ; first visible segment flattened, trans- 

 versely wrinkled, darker in color ; anterior spiracles small, hand-like, 

 slightly projecting, black; second segment low-arched, the succeeding 

 segments more highly arched until posteriorly they become almost 

 cylindrical ; the anterior segments on their lateral edges above have a 

 well marked longitudinal angular depression, outside of which the mar- 

 gin is produced and rounded ; the terminal dome-shaped processes bear- 

 ing the shrunken larval stigmata are prominent but less regularly shap- 

 ed than in the larva, concentrically wrinkled, and the dorsal area im- 

 mediately preceding them is also roughened and transversely wrinkled ; 

 length, 3.5 mm. ; pupation usually occurs among the dry insect remains 

 or on the inner wall of the leaf often well up toward the orifice or even 

 in the hood; pupal stage (in August) eight to ten days. 



$ $ . Black, head and thorax not shining, surface roughened and 

 thinly white-pollinose ; mesonotum and scutellum studded with short 

 spine-like black hairs ; mesonotum three-striped, with an additional 

 abbreviated dark stripe above each wing base; abdomen dark brown 

 above (almost black when dry), broad, flattened, slightly glossed, micro- 

 scopically punctate, finely haired; logs yellow and black.
