INSECTA — ORTHOPTERA. 
223 
0. vulgare, allied to the species above mentioned; but it differs in 
the tegmina being as long as the under wings, and the male having two 
black spots upon them ; it is very plentiful in the meadows : 0. gracile 
is like the preceding, but smaller (its length to the tip of the wings is 
7-8'"), the wings projecting a little from beneath the tegmina, and the 
male having no black spots upon them. Lastly, a species of Conoce- 
phalus, which is mentioned in the Catal. of Ins. of Massachus., under the 
name of ensiger, and appears to the author to be different from C. dis~ 
similis, Serv. ; it is green, with a whitish head, and has the mark of a U 
under the tooth, which is directed downwards to the cone on the fore- 
head, the ovipositor of the female is straight, and above 1" long, the 
length to the tip of the tegmina lf-2". 
Charpentier (1. c. s.) has figured both sexes of Phaneroptera ma- 
cropoda, Burn, {dalmatina, Serv.) ; Ph, cruenta, Burm., and a new 
German species, Locusta caudata, resembling the L. viridissima, but 
smaller, and with a longer ovipositor, and without the brown stripe on 
the head and prothorax, or the brown on the inner base of the tegmina, 
and having a black spine on the posterior thighs. 
The Locustm occurring in Denmark have been arranged by Schiodte 
(Kroyer Naturhist. Tidsskr. iv. No. 3, p. 316). There are seven 
species. 
Siebold read his observations on the spermatozoa of the Locustidce, 
at the meeting of Naturalists at Mainz (1842). They are of a peculiar 
form, consisting of a long flat body, which gradually passes into a long 
very tender thread, terminated by a V-shaped appendage. This, as well 
as the body, is stiff ; but the threads are very flexible. In the simple 
receptaculum seminis of the female Locustce, after copulation, the semi- 
nal mass is found to be contained in several bags ; in these are observed 
peculiar filiform bodies, winding round each other with undulating mo- 
tions. On minute examination, it was discovered, that these filiform 
bodies were composed of the spermatozoa, which attach themselves to 
each other by the V-shaped appendage. (Amtl. Bericht, &c. p. 223.) 
Acridites. — Charpentier (1. c. s.) has enriched this family with one 
new genus Sphenarium (Fasc. vi. t. 31), most nearly allied to Pyrgo- 
morpha, by its oblique face, with the top of the forehead projecting for- 
wards, fourteen- jointed antennae and large claws on the hinder tarsi, but 
apterous, with small narrow stumps of tegmina, and a short thickened 
body, fusiform in the middle ; Sph. purpurascens is from Mexico (a whole 
series of nearly allied species of this excellently conceived genus, and all 
from the same country, are preserved in the Berlin collection). Charpen- 
tier has also figured Tropinotus discoideus, Serv. (t. 32), and Acridium 
tarsatum, Serv. (t. 22), both from Brazil ; Ereinobia muricata, Gryll. 
muricatas, Pall. (t. 23), from the south of Russia ; and E. limbata (t. 24), 
a new species from Turkey.
