NEMATOCERA. 51 



Hor)iiomyia, \j^. = Angelinia, Rd. 



This sub-genus is distinguished by the gibbose thorax, which is 

 often drawn over the head. The second longitudinal vein ends as 

 in the preceding sub-genus. Wings without lustre,

Asp/i07id\'lia, Lw. = -1 -^ ' •' 



• Fhyllophaga, Rd. 



Antennae with short hairs of equal length ; joints cylindrical and 

 sessile ; no verticils. Same number of joints in $ and ? . Second 

 longitudinal vein reaches the mnrgin of the vving, beyond its tip. 

 Wings shiny. 



Dirhiza, Lw. 



Joints of antennse sessile in both sexes. Second longitudinal vein 

 hardly undulating before the cross-vein. 



Efiidosis, Lw. = Porricondy/a, Rd. 



Joints of antennce pedicelled. Second longitudinal vein is sinose 

 before the cross-vein. The cross-vein runs obliquely, commencing at 

 the root of the first longitudinal vein in the last two sub-genera 

 (Fig. 3a). Li the others the cross-vein commences in the middle of 

 the first longitudinal. 



Asyiiapta, Lw. = Wintietzia, Rd. 



Has four distinct longitudinal veins — all other sub-genera having 

 three — the last being divided. Reputed British (Fig. 4A). 



B. The second section is not satisfactorily classified. Loew 

 considers the members of this section as forming a sub-section of 

 the Cecido/nyidcv. Winnertz isolates them as a separate and distinct 

 family between the Cecids and the Mycetophilids. Brauer places 

 most in the dxido/nyidic and some in the Mycetopliilidcc {Zygoneurd). 



The following are the more important genera of this section : 



Cafocha, Hal. = Macrostyla, Wtz. 



Ocelli present. Wings hairy. Third longitudinal vein forked, 

 the upper branch forming a single smooth curve. The ^ has verti- 

 cillate antenna, composed of sixteen pedicelled joints. ? antennae 

 ten-jointed, joints moniliform (Fig. 5A).

Ocelli present. Wings hairy. Fourth longitudinal vein forked. 

 Antennae 11-20 joints, moniliform in J, with pedicelled joints. 

 Sub-moniliform, with sessile joints in $ (Fig. 6a).
