THE INSECTA. >§, 350. 



these fasciculate, 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 those tubes are few in number, they are but rarely 

 disposed in simple or double regular series.*^'') AVith most species, the 

 Receptaculum seminis is cuneiform and often arcuate ; its internal walls 

 are brown, solid and horny, and it comnmnicates with the vagina or copu- 

 latory pouch by moans of a long, flcxuous, spiral Ductus senmialis. With 

 many species, this receptacle is invested with a muscular apparatus, com- 

 })osed 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 appendicular is, which is sometimes provided with 

 a long, tl'xuous excretory duct.^^*" Sometimes the entire Receptaculum 

 seminis is composed of only a simple, rarely bifurcate, somewhat long c-e- 

 cum.'*"' Most of the Hydrocanthari, and some Carabidae, with whidi the 

 Ductals seminalis is inserted on the copulatory pouch, have the peculiarity 

 that there arises from the Receptaculum seminis a special Fecundatory 

 canal which opens into the upper portion of the vagina.*^'" A Bursa 

 copulatrix exists, generally, in this order. W^ith 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 clor.ca-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.*^^
