from two to four hundred eggs; this nest, with the gallery that 
leads to it, resembles a ale with a curved neck. The young 
remain together for some time. For other details, see the ob- 
servations of M. Le Feburier, Nouv. Cours d’Agriculture *. 
Tripacryius, Oliv.—Xya, I/lig. 
These Insects also excavate the earth, but with the anterior legs 
only ; in lieu of posterior tarsi, they are furnished with moveable, 
narrow, hooked appeu Jages, resembling fingers. The antenne are of 
equal thickness, very short. and consist of ten rounded joints. 
ye variegatus; ; Xya variegaia, lllig.; Chapent., Hor. Entom., 
Il, p. 84, f. 2, 5. Very small; black, with numerous spots or 
dots of a yellowish-white; a great jumper. South of France, 
on the shores of rivers +. 
GRYLLUS proper, 
Where none of the legs are adapted for digging, and where the pos- 
terior extremity of the female*abdomen is provided with a salient 
ovipositor, 
Their antenne are always elongated, smaller near the extremity, 
and terminate in a point. The simple eyes are less distinct than in 
the Tridactyli and Gryllo-talpe. 
G. campestris, L.; Roes., Insect., IT, Gryll., xii. Black; base 
of the elytra yellowish; head large ; posterior thighs red be- 
neath. It excavates deep holes by the roa: dside, in dry soils, and 
in situations exposed to the sun, where it remains in ambush, 
watching for the insects on which it preys. There also the 
female lays her eggs, which amount to three hundred. This spe- 
cies hunts the following one. 
G. domesticus, lu.; Rees., Insect., H, Gryll., xii. Pale-yel- 
lowish mixed with brown. It frequents those parts of houses in 
which fires are generaliy kept, and which furnish it with both 
shelter and food, as behind chimnies, ovens, &c. Such are also 
its breeding places. The male produces a shrill and disagree- 
able noise. 
Spain and Barbary produce a very singular Gryllus, the G. 
wmbraculatus, L. The forehead of the male is furnished with 
a membranous prolongation, which falls like a veil. 
MM. Lefevre and Bibron have brought from Sicily a new 
and large species, described by the former under the name of 
megacephalus; its stridulous noise is prolonged for half a mi- 
nute, and may be heard at the distance of a mile. 
The wings of the G. monstrosus form several spiral convolu- 
tions at the extremity ¢.
