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, Isodoiitni, or the indications of 

 their presence; and if the se.oon and locality be l.ixoruble, 

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

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