Gnophomyia fraterna, sp. n. (Fig. 6, p. 356.) 



Coloration and wing-venation as in G. maculipleura, but 

 the antennae a little shorter, the pubescence on the flagellum 

 longer and the hairs shorter, so that the difference in length 

 between pubesceuce and hairs is not so noticeable ; male 

 genitalia (fig. 6) of quite different structure ; pubescence of 

 wing-veins rather more evident. 



Selangor {A. L. Butler), 1 J . 



Gnophomyia nigrescens, sp. n. 



Whole body, except the ovipositor, blackish, somewhat 

 shining. Antennae a little longer than the head and thorax 

 together, with long hairs as in G. maculipleura, but here the 

 flagellar pubesceuce is rather longer and less regular. Ovi- 

 positor reddish-brown, of siuiilar structure, but rather longer 

 than that of G. maculipleura. Wing as in G, maculipleura ; 

 legs rather darker.

Oxy discus umbrosus, sp. u. 



? . Head dull grey ; front almost silvery, broad and 

 rather swollen. Antennae 15-jointed, first joint yellowish, 

 dark at the tip, second joint whitish, remainder blackish ; 

 joints 3-5 rather broadly oval, joint 6 cylindrical, a little 

 longer than broad, joints 7-15 cylindrical, rather more than 

 twice as long as broad. Thorax : mesonotum shining 

 ochreous-brown, without markings ; pleurae light ochreous 

 with two indistinct dark stripes. Abdomen dark brown, 

 ovipositor lighter. Legs almost uniformly light ochreous, 

 only the apical tarsal joints lighter. Wings slightly greyish 

 with darker clouds at the tips of all the veins (except Sc) 

 and over the cross-veins ; additional dark clouds over the 

 base of Rs, at the base of the forks of Mi and M2, and in 

 the middle of cell 1st Ei. Tip of wing slightly hairy. Rs 

 augulated near the base, the cell 1st Rj rather broad ; 

 mai'ginal cross-vein vertical, placed exactly at the fork of 

 R24.3; cross-vein R-M meeting Mi^s a little above the fork, 

 so that cell 1st M2 does not quite come to a point at the 

 base ; fork of Mi and M2 scarcely as long as the second 

 section of Mi^.2 ; second section of M3 straight and scarcely 

 longer than the cross- vein connecting it with Mj^.2; Ax 

 turned rather sharply downwards at the tip. Halteres light 

 ochreous. 



Length of body 4 mm.; wing 4 mm.
