68 MYCETOPHILIDiE. 



the 4th vein. The markings vary within reasonable limits. 

 Halteres clear orange-j-ellow. 



Length 9-10 millim. 



Described from a nearly perfect female in the Indian Museum 

 from Sylhet, 27. v. 05 {Lt.-Col. Hall, type), and four females in 

 my collection from Kandy, Ceylon, v. and vii. 09 {E. E. Green). 



Apparently the largest known Oriental Mycetophilid. 



Subfamily SCIOPHILIN^. 



This subfamily is represented by a well-circumscribed set of 

 species numerously distributed throughout the world and possess- 

 ing a characteristic cell formed by the upper branch of the 3rd 

 longitudinal vein being so short, so upright, and placed so soon 

 after the origin of the vein, as to be almost parallel to the upright 

 short basal section of the vein, thus enclosing a more or less four- 

 sided cell, x^'hich I propose to term the " sciophiline cell," from its 

 being peculiar to this group. Anterior cross-vein present, 

 subcostal cross-vein present or absent, posterior cross-vein ahx ays 

 absent. Two or three ocelli present, always remote from the eye- 

 margius except in one (non-Oriental) genus, Eudicrana, Loew. 



Table of Genera. 



The 4tli louoitudiiuil vein forks at or a little 

 beyond anterior cross-vein ; fork of 5tli 



longitudinal vein beyond fork of 4th . . Sciophila, Mg., p. 68. 



The 4th longitudinal vein forks at least the 



length of the anterior cross-vein beyond 



the latter. 



The 3rd longitudinal vein very sinuate. 



Auxiliary vein ends free or in the 



costa beyond the sciophiline cell. 



Three ocelli, the middle one only a 



little smaller than the laterals Poia'LEPTa, Winn., 



The 3rd longitudinal vein straight or gently [p. 78. 



curved. Auxiliary vein ends either 

 in the costa, in the 1st longitudinal 

 or free. Ocelli two or three; when 

 three, placed together in a triangle in 

 middle of frons, the middle ocellus 

 very minute Mycojiyia, Rond., p. 70.
