456 THE INSECTA, $ 850, 
these fusciculate, there are, also, here and there, botryoidal ovaries, in which 
there are numerous imbricated tubes inserted on a large calyx of each of 
the oviducts.“? When these tubes are few in number, they are but rarely 
disposed in simple or double regular series.“ With most species, the 
Receptaculum seminis is cuneiform and often arcuate; its internal walls 
are brown, solid and horny, and it communicates with the vagina or copu- 
latory pouch by means of a long, flexuous, spiral Ductus seminalis. With 
many species, this receptacle is invested with a muscular apparatus, com- 
posed of striated fibres, and which undoubtedly is a compressor. Usually, 
there is, attached to the base of the receptacle, a simple, rarely bifurcate 
or multiramose, Glandula appendicularis, which is sometiines provided with 
a long, flexuous excretory duct.“ Sometimés the entire Recep/aculum 
seminis is composed of only a simple, rarely bifurcate, somewhat long cae- 
cum.“ Most of the Hydrocanthari, and some Carabidae, with which the 
Ductus seminalis is inserted on the copulatory pouch, have the peculiarity 
that there arises from the Receptaculwm seminis a special Fecundatory 
canal which opens into the upper portion of the vagina. A Bursa 
copulatrix exists, generally, in this order. With only a few species, it 
consists of a simple dilatation of the vagina, but, usually, it is a rather 
long, muscular caecum, separated from the upper wall of the vagina, and 
sometimes even flexuous when its length is considerable. Very often, 
the vagina is quite long, curved S-shaped, and passes with the rectum into 
a cloaca-like canal. It has a complicated special muscular apparatus. © 
The glandular appendages of the vagina are wanting with the Coleoptera, 
but, with the Hydrophilidae, there are two multiramose appendages on the 
oviducts, which are probably sebaceous organs.” The same function may, 
perhaps, be attributed to the glandular walls of the upper extremity of the 
oviducts of the Staphylinidae and Histeridae.™

burg, Mediz. Zool. II. Taf. XVII. fig. 2. 
re The ovaries are in single rows with Macrony 
chus, Oxytelus, Silpha, and Byrrhus ; but thy 
are in two rows with Stenelmis, Lycus, Oedeme- 
ra, and Hydrobius ; see L. Dufour, Ann. d. Sc. 
Nat. III. 1835, Pl. VII. fig. 25,275 and Stein, 
loc. cit. Taf. IIL. fig. 83,16, Taf. IV. fig. 3, 4, and 
Taf. VI. fig. 8. There is a very remarkable dispo- 
sition, according to Stein (loc. cit. p. 30, Taf. I. 
fig. 4), with Dianous caerulescens, Myrmedonia 
caniculata, Homalota canaliculata, and a spe- 
cies of Trichopteryx, which, alone among all 
known Insecta, have only a single ovary and a 
single oviduct, the first being composed of ten to 
twelve tubes disposed in two rows.

seminis of the Coleoptera, see L. Dufour, Ann. d. 
Sc. Nat. VI. 1825, and ILI. 1835, &c. ; Siebold, in 
Miiller’s Arch. 1837, p. 404, Taf. XX. fig. 1, and 
especially Stein, loc. cit. p. 96, with the corre- 
sponding figures. With the Elateridae, the acces- 
sory gland is distinguished by a very complicated 
structure and numerous ramifications ; see 4. Du- 
Jour, Ann, d. Sc. Nat. VI. 1825, Pl. XVII. fig. 
8-10, and Stein, loc. cit. p. 129, Taf. V. The sem- 
inal receptacle is wholly wanting with Xantholi- 
nus punctatus, Lathridius porcatus, Notoxus 
monoceros, and Lagria hirta; see Stein, loc. 
cit. p. 93. 
49 With the Carabidae, and some Staphylinidae. 
The seminal receptacle is double with Stenus and 
Paederus ; see Stein, loc. ‘cit. p. 97, Taf. L. ILi.

53 There is a long, flexuous, muscular vagina 
with the Cerambycidae, Curculionidae, Elateridae, 
Buprestidae, and most of the Heteromera ; also, 
with the Histeridae, Dermestidae, Parnidae, &c.; 
see Stein’s exact descriptions, loc, cit. p. 71, Taf.

54 See Stein, loc. cit. p. 33, Taf. IV. fig. 3 
(Hydrobius fuscipes). With Hydrobius piceus, 
and caraboides, there are even two kinds of anal- 
ogous appendages. One consists of eight bifurcate 
follicles, the other of simple tubes inserted on the 
calyx of the oviducts; see L. Dufour, Ann. d. 
Sc. Nat. VI. 1825, p. 445, Pl. XVIII. fig. 5, and 
Suckow, in Heusinger’s Zeitsch. IL. Taf. XIII. 
fig. 34. The bifurcated appendages were over- 
Jooked by this last naturalist. It is well known 
that the females of the Hydrophilidae enclose their 
eggs by groups in a cocoon Cyanets Mém, du 
Mas. &c. XVIII. p. 454, Pl. XXIV.) which those 
of Spercheus carry about attached to their poste- 
rior legs.
