identified it as a Sciara, but could not refer it to any of the species 

 listed in the Osten Sacken Catalogue of Diptera, and, therefore, 

 accepted it as undescribed. 



Prof. Riley, in a notice of the above paper in the American 

 Naturalist, xv, 1881, p. 150, quotes the occurrence of another unde- 

 scribed species of Sciara, where the flies came out in millions from the 

 joinings of the floor boards in an upper room of a new addition to a 

 semioary building in Bethlehem, Pa. 



The Apple-Midge. 



Still another species possessing particular interest from the 

 habitat of its larva differing so greatly from that of most of those of 

 its congeners, is Sciara mail, originally described by Dr. Fitch in his 

 Second Report on the Insects of New York, as Ifolobrus mali, found 

 by him in its pupal and winged stages in the center of an apple that had 

 been eaten and perforated by the " apple-worm " of the codling-moth. 

 Dr. Fitch was of the opinion that the eggs of this midge are deposited 

 on apples that have been attacked by the apple-worm, and that the 

 larva3 enter the fruit through the perforation in the side made by the 

 worm . , 



This species is apparently rare . I have never met with it, and I am 

 not aware of any important contribution to its habits or life history by 

 recent writers . It is not so much as referred to in Osten Sacken's 

 revision of Characters of the Larval of Mycetophilidm,v& 1886. It 

 will be of interest to know if the larva feeds on the pulp of .the fruit or 

 on the excremental or decomposed material associated with the presence 

 of Garpocapsa p)omonella and Trypeta pomonella — the latter the 

 probable burrower of the apple in which the insect was found by Dr. 

 Fitch. 



Sciara coprophila n. sp. 



The Manure- Fly . 



(Ord. Diptera: Fam. Myc&tophilid^e ) 



Examples of the above fly were brought to me on March 20, 1889,* 

 from a gentleman in Albany who was growing mushrooms in his 

 cellar. He believed that the larvae injured the mushrooms by eating 

 into the stalk near the surface of the bed. Although I have no notes 

 stating the fact — if my memory serves me correctly, some of the larvae 

 received at this time were carried to their winged state by feeding 



* Reference to this was made in the Fifth Report on the Insects of New York, 1889, p. 265.
