Rhaphium flavipalpe Ztt. PLATYPEZIDJE Platycnema, two species, type 

 Empis pulicaria Fin. Microsania, including Cyrtoma pectipennis Mg. 

 and a second species, differs from the preceding chiefly in venation, the 

 cubital vein running to the hind margin. PIPUNCULID.E Nephrocerus, 

 antennae with the third joint reniform, the venation nearly as in Pipuncu- 

 lus auctus; two species, larger than any of that genus. MUSCIDJE, 1. 

 CALYPTERI Micra, placed next to Phania, the clothing pubescence with- 

 out bristles, the abdomen ovate ; one species M. Trixina, 2 lines long, a 

 single specimen found in Northland. Wahlbergia, type Tachina melanura 

 Mg., allied to Ocyptera, the radial vein longer and not curved, the angle 

 of the subapical vein more obtuse, the alulae smaller. Gymnopeza, distin- 

 guished from Phasia by the nearly naked body and legs, and the gentle 

 curvature of the subapical vein, which joins the cubital exactly at the end, 

 and resembling Phania by the incurved extremity of the abdomen ; two 

 species, scarcely exceeding 2 lines in length. Cinochira, of rather 

 doubtful affinity ; the subapical vein approaching the cubital with a slight 

 curve towards the end, the alulae pretty large, antennae with the third joint 

 not longer than the rest, rounded, the arista long and capillary, eyes dis- 

 tant (in male ?) ; one species C. atra, 2 J lines long ; allied to the Tachi- 

 nides in the opinion of Wahlberg the discoverer, but placed by Zetterstedt at 

 theend of tlieMuscides, immediately before iheAnthomyzides. 2. ACALYPTERI 

 Leptopa, one species L.filiformis Ztt. (Cordylura flava Hal., Ent. Mag. 

 A.D. 1836, but Wiedemann had previously a C. flava from Egypt); sepa- 

 rated from Cordylura on account of the shorter antenna and oblong eyes ; 

 the orbits of the face very prominent below, where they bear the ordinary 

 " mystacine" cilia. Ectinocera, differing from Tetanocera in the com- 

 parative length of the joints of the antennae, the third being elongated, and 

 the two preceding short ; E. borealis, a northern species, 2^ lines long. 

 Psceroptera Wlbg., allied to Ortalis, and the wings spotted in like man- 

 ner, hypostoma short not keeled, habit of Sepsis; four species, from 1-J to 

 3 lines in length ; frequent the trunks of trees, running with the wings 

 extended horizontally in constant motion ; the larvae feed under the bark. 

 Colobcea, type Opomyza bifasciella Fin. (Sciomyza concentrica Mg.). 

 Rhynchcea, resembling Lonchcea, but the oral angles of the face armed 

 with a bristle ; one species Rh. lonchceoides, 1^ line long. Macrochira 

 (Clusia Hal, Ann. Nat. Hist, ii., 188, A.D. 1838), type Heteromyza flava 

 Mg., but Zetterstedt has not recognised their identity, though he happens 

 to have adopted the same trivial name. Amphipogon Wlbg., much re- 

 sembles the preceding, but the round third joint of antenna? bears the 

 naked arista near the base ; one species A. spectrum Wlbg., between 2
