102 The Rev. Wm. Kırzy on a new Order of Insects. 
alternately at right angles by an infinity of transverse ones, so 
that their reticulations, or little squares, are usually arranged like 
bricks in a wall: in Forficula, indeed, the nerves are chiefly lon- 
gitudinal, but they are all connected near the margin by a trans- 
verse one which surrounds three-fourths of the wing. 
From the. peculiarities here stated, I trust I have made it evi- 
dent, as far as the el ytra or the wings are concerned, that these 
insects will not arrange under any of the present orders. 
I shall now say something on the remaining characters of the 
Stylopide, beginning with what Mr. Spence and myself, in our 
proposed elementary work, have denominated Trophi (Feeders) *. 
Upon these the Fabrician orders are professedly founded, and 
therefore this will enable us to judge whether our insects will 
arrange under any of them. The whole of the orders established 
by that system may be divided into two principal classes; those 
that masticate their food, or at least have mandibule and maxillz, 
and those that imbibe it by suction ; in the first we have Eleu- 
therata, Ulonata, Synistata, . Piezata, Odonata, Mitosata, Unogata, 
and all the Crustacea. The characters of this class are all taken 
from the maxilla or under-jaw: under the second, the suckers, 
are arranged the Glossata, Ryngota, and Antliata ; the characters 
of these are taken from the tongue or haustellum, which is an- 
other name for it. Now in the insects in question, the Stylopide, 
neither maxille nor tongue are discoverable; they are armed in- 
deed with what, as well as Professor Peck, I am disposed to 
consider as mandibule or upper-jaws, but which are not formed 
for mastication ; these mandibul:e, unlike all others, are fixed in 
the head on its under-side, between the palpi at their base f, a 
* Fabricius names the parts in question Instrumenta cibaria ; but having laid it down as 
a rule not to employ compound terms, where it was possible to avoid it, except to express 
qualities, we have substituted the above for those of Fabricius.
