second branches. Lampronia and Incurvaria (Staint. pl. 2. figs. 
1 & 3) are excellent examples of this arrangement. This character 
does not occur in the Oiketici, the veins of which, on the other hand, 
are more analogous to some of the Bombycidve, such as Limacodes. 
These considerations are, I think, sufficient to disprove the relation 
of Otketicus and Psyche with the Tinee, and to establish their 
position among the Bombyces. 
DESCRIPTION OF THE PLATES. 
PLaTE XXXIV. 
Oiketicus nigricans. (Great Britain.) 
Fig. 1. Female magnified, seen sideways, drawn from living specimen. 
Fig. 1a. Head and anterior segments of the body, seen from beneath, showing the 
rudimental eyes, antenne, and legs. 
Fig. 1b. The same, seen sideways. 
Fig. 1c. The lower part of the face, showing the transverse membrane capable of 
alternate dilatation, and the small exarticulate antenne. 
Fig. 1d. The terminal segment of the body, showing the produced bilobed append- 
age and the central terminal elongated joint. 
Fig. le. The same seen from beneath, the bilobed appendage seen almost vertically. 
Fig. 1f. The same, seen sideways. 
Fig. lg. The case formed by the female larva. 
Fig. 1h. The pupa case of the female; slit behind the head for the exit of the insect. 
Fig. 1i. Fore wing of the male:—1, costal vein; 2a, 2b, 2c, 2d, 2e, branches of 
the subcostal; (a, upper discoidal, wanting) y, lower discoidal; 31, 32, 
33, the branches of the median vein; 4, submedian vein. The same let- 
tering is used throughout the wings represented in this and the three 
following plates (except that the branches of the subcostal have occasion- 
ally been numbered 21, 22, 23, 24, 25), occasionally one of them is wanting, 
or the lower discoidal is wanting, instead of the upper; in these cases the 
place of the wanting branch is indicated by a < and the indicatorial letter 
in the place which it ought normally to occupy.

Fig. 2a. Antenna of the male. 
Fig. 26. Fore leg of the male.

spots indicating the palpi.

extremity,

Figs. 5, 6, & 7. Cases of three Australian species in the Collections of Mr. Saunders 
and myself, of which the transformations have not yet been observed.
