the anterior pair of legs* : whereas in Coleoptera and Orthoptera 
their point of attachment to the trunk is dorsal, by means of an 
apophysis or kind of pivot, which acts under the posterior part 
of the thoracic shield ; and they cover the back; the wings, 
where they exist, for the most part entirely, though in some few 
genera only partially; and the abdomen. In connection also 
and direction they are quite unique, there being nothing at all 
‚similar to them in any order; for they are entirely and widely 
separated from each other, coming in contact in no one part, at 
first receding from the body, then curving towards it, and lastly 
diverging from it againt, so as to give them the appearance of 
distortion. In Coleoptera it is well known, with the exception of 
Melöe Fabr. (the elytra of which diverge from each other consi- 
derably, though at the base one laps over the other) that, when 
closed, they unite together at the longitudinal suture$. In all 
the Orthopterous genera one elytrum laps more or less over the 
other|; in a few species of Phasma and in Acrydium the elytra 
are very minute, and may perhaps be deemed more analogous to 
those of Stylops and Xenos; still, even in these cases, when closed 
they cover the base of the wings, are dorsal, and remote from the 
head. The elytra, therefore, now under consideration, whether 
we advert to their situation, direction, or connection, cannot be 
regarded as indicating the arrangement of these insects under 
any of the present orders.

Kew Green, who has been kind enough to enrich this paper with such a drawing as 1 be- 
lieve has scarcely a parallel in Entomology.

though not so much as they do in Melee. 5
