4 Mr. E. Newman's Notice of 



the orifice, and made about the tliickness of common brown 

 paper. There is no great difference in the size or form of the 

 chrysalids which produce the male and female moths; they are 

 about three-quarters of an inch in length ; on both of them the 

 sheaths for the wings, antennae and legs are alike, and are as 

 plainly to be seen as on the chrysalids of other winged moths. 

 The chrysalis tapers very little, and does not end with a point, 

 but is blunt behind; and on the edge of each of the rings of the 

 back there is a transverse row of little pointed teeth, which shut 

 into corresponding notches in the ring immediately behind them. 

 These teeth are evidently designed to enable the chrysalis to 

 move towards the mouth of its case, and to hold with when it is 

 engaged in forcing off the lid in order to allow of the escape of 

 the moth.

Both sexes leave their cocoons when arrived at maturity, 

 and both are provided with wings. Their feelers are of moderate 

 size, cylindrical, blunt, pointed, and tliickly covered with scales. 

 The tongue is not visible. Their antennae are curved, and are 

 recurved or bent upwards at the point ; the stalk is feathered in 

 a double row, on the underside, very widely in the males for 

 more than half its length, and beyond the middle the feathery 

 fringe is suddenly narrowed, and tapers thence to the tij) ; in 

 the females the antennte are also doubly feathered, but the 

 fringe is narrower throughout than in the other sex. The body 

 and the wings almost exactly resemble those of the foreign silk- 

 worm moth in shape; but the fore wings are rather more pointed 

 and hooked at the tip. There are no bristles and hooks to hold, 

 together the wings, which, when at rest, cover the sides like a 

 sloping roof, and the front edge of the hind wings does not pro- 

 ject beyond that of the fore wings. 



The neuration of the wings is very different from the typical 

 Bomhycidce, at least from that of the large Saturnice. The costal 

 nervure is faint, and terminates on the costal edge at two-thirds 

 length of the wings. Sub-costal throws off its first and second 

 nervures before the end of the cell; the second nervure being the 

 strongest vein in the costal part of the wing. The upper disco- 

 cellular nervure is very short and nearly transverse to the wing; 

 the middle is of the same length as the lower; the middle imper- 

 fect in its middle part, the lower perfect. The maxillae are ap- 

 parently wanting, and the middle spurs of the hind tibicfi are im- 

 perceptible, showing that the character, together with the an-
