Another Pitcher-Plant Insect (Diptera, 

 Sciarinae). 



By Frank Morton Jones, Wilmington, Delaware. 



(Plate I.). 



The captures of Sarracenia, especially those of the larger 

 southern species, offer many surprises: as we pass from one 

 tall "pitcher" to another, lifting their lids and peering down 

 the narrowing tubes, we find recent captures, — moths, beetles, 

 flies, wasps, grasshoppers, representatives of most of the prin- 

 cipal orders of insects, — attempting to scale the vertical walls 

 which have already proved fatal to the earlier victims whose 

 remains fill the lower tubes; we recognize the usual guest in- 

 sects, Exyra, Sarcophaga, Isodontia, or the indications of 

 their presence; and if the season and locality be favorable, 

 we may soon find a "pitcher" whose tube, some inches below 

 the top, is closed by a mass of whitish froth-like filaments
