160 Mr. H. Eltringham's Further Observations on the 



are not the dried granules of a secretion, since they are 

 unaffected by prolonged immersion in eau-de-javelle, 

 although particles of secretions which I have observed in 

 other species, however fully they may resist the action of 

 the various solvents used in preparing the sections, dis- 

 appear more or less readily when a drop of eau-de-javelle 

 is placed on the slide. The dust produced in this manner 

 in A. oclilea must be very small in amount as compared 

 with that formed in such species as niavius and psyttalea. 

 I have not reproduced photographs of sections of the 

 brush in A. ochlea, nor drawings of the wing-glands, since 

 compared with the same organs in A. egialea the differences 

 are so small as scarcely to warrant separate illustration. 



Amauris hecate, Butl. 



The wing-patch presents alternate rows of cupped and 

 blind glands, as may be seen in PI. XVIII, fig. 12, showing a 

 section parallel with the nervures. The gland-cells differ 

 considerably from those of A. egialea, in that they occupy 

 nearly the whole space between the wing-membranes. 

 The structure may be regarded as somewhat intermediate 

 between that of yiiavius and egialea. The scales on the 

 wing-patch, of which one is shown in fig. 10, are also inter- 

 mediate in shape. They cover the glands very incom- 

 pletely, though more effectively than those of egialea. 



The structure of the brush in A. hecate is also of an inter- 

 mediate character. PI. XIII, fig. 1, shows a section near 

 the base, from which it may be seen that there is a small 

 core of modified scales presenting in large part the char- 

 acters of both the central and first-ring bodies of egialea. 

 These die out rapidly and the greater part of the area of 

 the section is taken up by the yellow hairs, as shown in 

 PI. XIII, fig. 2, in which will also be noticed, on the side, 

 where the bag membrane is thinnest, a somewhat obscure 

 mass, unfortunately not very clearly in focus. This 

 represents certain flattened hairs which arise on that side 

 and become at higher levels (figs. 3 and 4) somewhat in- 

 vaginated on one side so as to present a reniform section. 

 These structures may perhaps be regarded as corresponding 

 with the third-ring bodies of egialea. In fig. 4 they 

 occupy a large area of the section and are obviously tending 

 to break up, a condition shown still better in fig. 5. They 

 arise from cells in the bag membrane, and in longitudinal
