The whole contour of the gland is thus somewhat ear-shaped. In A. trinitatis the glands are longer and of an even diameter throughout, The accompanying drawing (fig. 2) will show the difference between the two species in this respect. The duct of the gland, too, is rather longer in the present species. Fig. 2. B C Spermatheca; of : A, Amyntas heterochcetus ; B, A. trinitatis ; C, A. aiexandri. Fig. 3. A B- C Spermiducal glands of: A, Amyntas heterochcetus ; B, A. trinitatis; C, A. aiexandri. The spermatheca? (fig. 2) are four pairs and lie in segments vi.-ix. Their orifices to the exterior are not so dorsally placed as in A. trinitatis. The pouch, too, is distinctly different in form and the relations of its component parts. The duct of the pouch is longer thau the pouch and broadens towards the external orifice. |
