along the cord and outer end of cell Isl .V.j, and along the 

 wing-margin at the ends of all the veins : veins brown, 

 darker in the infuseated areas; the colour is produced by 

 very abundant macrotrichiae that cover the entire wing. 

 Venation: lis ending in cell Ry as in Molophilus ; row Ro 

 about its own lengtii beyoud the fork of Rs ; cell \st Mo 

 closed ; basal dcflectiou of Cu^ one-third its leugth or less 

 before the fork of M. 



Abdominal tergites dark, the colour almost concealed by 

 dense white setie ; stcrnites similar, but the apical margins 

 of the segments appear broadly whitish, due to the greater 

 abundance of sette. Male liypopygium with a median 

 dorsal (the apparent ventral) style ; on either side of this a 

 deeply bilid, slender appeudage, the lateral arm shorter, 

 sinuous, the apex acutely pointed ; mesal arm longer, decus- 

 sate across the mid-Hue, dilated near the ends, the extreme 

 tips of each produced into an acute black spine.

Amphineurus molophilinus is a very distinct fly that sug- 

 gests iu several respects a species of Molophilus, but has the 

 wing-membrane densely covered with macrotrichite and is to 

 be placed in Amphineui'us. 



Amphineurus harrisi, sp. n. 



Antennoe of male elongate; wings snbhyaliue ; cell R^ 

 petiolate ; cell ]st J/j open ; cell Mg sessile or nearly so; 

 male liypopygium with the ninth tergite terminating in two 

 parallel spines ; basal pleural appendage branched beyond 

 mid-length ; penis-guard terminating iu a long slender 

 spine. 



Male. — Length abont 4'5 mm. ; wing G"5 ram. 



Rostrum light brown : palpi dark brown. Antennae 

 elongate, a little shorter than the body ; flagellura appearing 

 subnodose as in the insulsus group of species ; tlagellum 

 segments elongate-fusiform, except at the distal cud with 

 abundant erect setae ; scapal segments brownish testaceous; 

 basal flagellar segments indistinctly bicolorous, dark brown, 

 the apex narrowly pale ; terminal flagellar segments uni- 

 formly brownish black. Head grey.
