1908] Reproductive Organs of Male Cimbex 201 



The glandular nature of the epithelial eells is shown by the 

 presence of secretory processes which arc somewhat similar to 

 those that we have described and figured in the mid-intestine of 

 Cimbex (t,s). Bordas (4) in his investigation upon the male 

 reproductive organs of Coleoptcra has described secretory 

 processes in the accessory glands of a species of Lucanus and 

 Dorcus parallelipipedus. In the process of secretion of Cimbex 

 the free end of the cell becomes swollen causing it to project above 

 the glandular cells at rest (Fig. 4, gl). The swollen mass elon- 

 gates and assumes a more or less pyriform shape (Fig. 5, A). 

 Further stages can be found in which the globules are still in 

 direct continuity with the protoplasm of the cell, from which 

 the}' originated, by a fine pedicel. Finally the globule becomes 

 free by strangulation and floats in the lumen of the glandula 

 mucosa (Fig. 5, B). 



Since Zander (39) who has worked on the morphology of the 

 male genital apparatus of various Hymenoptera, has described 

 the ejaculatory ducts and penis of Cimbex \'ariabilis, we made no 

 further attempt to examine these parts in Cimbex americana. 



We are deeply indebted to Prof. Wm. S. Marshall for the use 

 of literature which was borrowed from his excellent entomological 

 library.
