ORPHNEPHILA. 265 



two joints (first globose; second ovate, with a terminal arista, which 

 is a little longer than the first and second together), but under a good 

 lens they are found to be ten-jointed; the first thickest, globose; 

 second, third, and fourth compact into an oval mass ; the rest slender ; 

 fifth short ; sixth and following, to the tenth, linear, pubescent ; tenth 

 with two longer hairs near the tip. Thorax robust, gibbous ; scutellum 

 of moderate size. Wings oblong, with an obtuse anal angle; no dis- 

 tinct axillary lobe ; the ambient vein faint round the hind margin ; of 

 the longitudinal veins two end in the costa, two about the apex, three 

 in the hind margin ; there is an areolet closed before the middle of the 

 wing, with very irregular outward limit ; it is divided longitudinally by 

 an obsolete vein (the first part of the praebrachial vein), and represents 

 the confluent brachial areolets (nearly as in Bolitophila). Taking the 

 mediastinal vein to be obsolete, and the first longitudinal vein ending 

 before the middle of the costa to be the subcostal, we shall have a 

 simple radial ending beyond the middle of the costa, and a simple cu- 

 bital ending near the apex of the wing, these two connected by a per- 

 pendicular veinlet beyond the end of the proebrachial areolet ; three 

 simple externo-medial veins, two from the end of the prsebrachial, one 

 from the pobrachial areolet ; subanal vein produced from the posterior 

 apical angle of this last areolet, running to the margin not far beyond 

 the anal angle ; anal and axillary veins very faint or obsolete ; prrebra- 

 chial areolet longer than the pobrachial, but almost confounded with 

 it. Halteres elongated ; club rather large. Abdomen with seven seg- 

 ments, nearly cylindrical, moderately thick, a little narrower than the 

 thorax, and about twice its length. Legs simple, bare, unarmed, of 

 moderate and nearly equal length ; coxae short ; tibiae without spines ; 

 tarsi rather long, the foremost much longer than the tibia ; penultimate 

 joint shortest, emarginate at the tip, nearly obcordate. Ungues curved, 

 simple, acute. Onychia dilated. Etnpodium inconspicuous. Male. 

 With a double forceps, the outer very stout, two-jointed ; first joint 

 broad, subovate ; second slender, culthiform, acute ; inner forceps slen- 

 der, strongly incurved, armed at the tip with an inflected claw, and 

 with a smaller spine inside, some way before the tip. Fern. Tentacles 

 of the vagina broad, rounded at the tip.
