the smaller pressure on the light, friable brown coal coked, the 
lighter rising of the gases in the dense but low smelting column, 
and the possibility of more readily overcoming occasional inter- 
ruption, ought to be especially pointed out. Whilst I must 
refer you for the details of the matter to the book already men- 
tioned, I must leave it to the future, and to greater experience 
in the working of the blast, to determine whether this suggestion 
should come into everyday use.* 
* Professer Kupelwieser remarks that the practicability of the reduction of iron 
ore by brown coal has been shown by the experiments of Chenot and Blair. The 
difficulty arises in continuing the operation when sponge iron is produced; and the 
question then obtrudes itself whether this part of the work would not be suitably 
carried on in a small furnace with coked fuel, such as in a Siemens furnace as Blair 
tried to doit. In conclusion he thinks it best, under the present conditions, to urge 
not so much the application of brown coal alone, as the possibility of the combined 
use of brown coal in working the blast fnarnace, as he previously suggested in the 
year 1876 (vol. xxi. p. 253 of the ‘‘ Austrian Journal’), and the combined use of the 
blast furnace process with the Bessemer process, in certain cases in combination with 
the Martin process (vol. xxviii. No. 1 of 1880) in order by this combination to unite 
the shortest and most economical way for the production of wrought iron,

(ABSTRACT,) 
ee 
GENUS GLYPHIPTERYX, 0. 
Head smooth, with ocelli; tongue moderate. Antennz 
much shorter than fore-wings, slender, filiform, pubescent, or 
very shortly ciliated in males. No maxillary palpi. Labial 
palpi rather short, thick, arched; second joint laterally com- 
pressed, often roughly scaled beneath ; terminal joint as long as 
second, pointed. Fore wings elongate, variable in breadth, hind- 
margin often indented, oblique, apex rounded, often produced. 
Hind wings varying from ovate to lanceolate, narrower than 
fore wings, cilia rather narrower or broader. Abdomen rather 
elongate. Legs rather short, smoothly scaled. Fore wings with 
12 veins ; secondary cell indicated ; 7 and 8 separate ; 1 simple, 
or more or less furcate at base. Hind wings with 8 veins; 
3 and 4 from posterior angle of cell, sometimes short 
stalked. 
The genus may always be recognised by the short palpi 
clothed with whorls of scales, and metallic transverse markings. 
All the species have the same habit of alternately raising and 
depressing their wings when at rest, as though fanning them- 
selves. They are sun-loving insects, and fly especially in the 
afternoon towards sunset, in grassy places. 
The larvee are 16-legged, rather stout, and feed principally 
on the seeds of grasses and allied plants, except one European 
species on Sedum. I have not yet succeeded in finding the
