these fVtsciculate, 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 sometimes provided with 

 a long, flexuous excretory duct/^**' Sometimes the entire Receptaculum 

 semuiis is composed of only a simple, rarely bifurcate, somewhat long cae- 

 <3,j,jj/49) 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 Receptaculum seminis a special Fecundator}' 

 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.'^^'
