with four or five very obsolete veins, the tip armed with a long curved 

 bristle, which is triple in the female, antennae 12-jointed, the first joint 

 short and stout, the last oblong and thickened, the intermediate joints small, 

 globose, and compact; one species C. ambigua, 1-^-2 lines long, found on 

 the shore of a lake in Tornea Lapland. TIPULID.E Psiloconopa, wings 

 divaricated, venation nearly as is Limnobia, Mg. Zw. i. t. 5, f. 6, antennae 

 16-jointed, moniliform, eyes meeting under the antenna?, proboscis short, 

 palpi 4-jointed ; one species Ps, meigeni, 3 lines long, like Erioptera late- 

 ralis in colour ; found throughout the northern provinces in watery places. 

 Tricyphona, distinguished from Limnobia by the peculiar venation, type 

 L. immaculata, Mg. Zw. i. t. 5, f. 8. Dicranota, antenna? 13-jointed, type 

 Limnobia pavida Hal. (D. guerinii Ztt.), and it seems to us that L. bima- 

 culata (Schiimmel) is congenerous, although Zetterstedt has left that species 

 among his Limnobice. LEPTIDJE Ptiolina Stg., dismembered from 

 Atherix, third joint of antenna oval, with short apical arista; e.gr. A. 

 melcena Mg. BOMBYLID^E Psilocephala, founded on the species of The- 

 reva with naked face ; but Loew (Beytr. ii.) has retained them as a portion 

 of that genus. ACROCERID.E Sphcerogaster, resembling Cyrtus in the an- 

 tennae and exserted proboscis (which is horizontal and as long as the head), 

 and Henops in venation ; the alulae very small ; one species Sph. arcticus, 

 little more than ^ line long, a single specimen found on a mountain of Fin- 

 mark. EMPIRE Anthalia, like Euthyneura, third joint of antennae ovate, 

 without a style, hind femora rather long ; seven species, almost exclusively 

 northern; A.furcata^ having the cubital vein forked, should probably be 

 removed from this genus. Iteapkila, like Euthyneura, but the cubital 

 vein forked ; two species, chiefly northern. Hormopeza, seems to come 

 near to Ragas, but the third joint of the antenna? is ovate, and the style 

 longer in proportion, the fore tarsi moniliform in the male ; one species H. 

 obliterata, above two lines long; Toruea Lapland and the north of Bothnia. 

 Microcera Ztt. is synonymous with Sciodromia. Phyllodromia, type 

 Tachydromia melanocephala Fabr., differing from Hemerodromia chiefly 

 by the simple cubital vein. Wiedemannia, type Heleodromia bistigma 

 Curtis (W. borealis Ztt.)] Wahlberg has remarked that longicornis is the 

 only genuine Brachystoma, and that the other species referred to that 

 genus by Zetterstedt belong to Paramesia Macquart (synonymous with 

 Heleodromia) ; we would add that both Heleodromia and Wiedemannia, 

 and, perhaps, Ardoptera too, might be reunited with Clinocera; and 

 Wiedemannia has been employed as a generic name, not only in another 

 family of Diptera, but in botany also. DOLICHOPIDJS Thinophilus, like 

 Rkaphwm, but the third joint of antennae round, with dorsal arista ; type
