two ears, or two cylindrical bodies, terminating in a point, 
which emerged from the first segment behind the head?. 
In another observed by the same author, the legs were 
replaced by a single horn, but which did not appear to 
send forth an internal one: from the back of its fourth 
segment also emerged a single conical or pyramidal fleshy 
eminence or cleft, terminating in two points>, Some of 
the tropical butterflies also, as may be seen in the figures 
of Madame Merian, have two diverging anal horns in- 
stead of anal prolegs; but it does not appear that they 
incase tentacula®. Wherever these caudal horns are 
found, the above prolegs are wanting’. ‘Two conical 
anal horns also distinguish the caterpillar of one of the 
moths called Prominents, Lophopteryx camelina ; but 
these are not terminal, but on the back of the last seg- 
ment but one’. In that of another British moth, Noto- 
donta ziczac, there are three dorsal prominences, one 
near the anus, and two more in the middle‘. Some 
Geometers (G. fuliginosa, Ros. &c.) have two erect 
horns on the eleventh segment, and others (Pericallia 
syringaria, &c.) two recurved ones on the eighth’. I 
must not here omit to mention the curious hooks emerg-

@ This is not, however, universally the case, for the caterpillar of 
a Geometer described by Reaumur (ii. 363. #. xxix. f. 8.) (Ennomos 
amatoria) has a pair of fleshy anal horns, terminating, it should seem 
from his figure, in a minute hook that the animal uses as a forceps ; 
which has at the same time the anal legs, of which indeed these horns 
seem to be appendages.
