STATES OF INSECTS. (Larva.) 115 
Menelaus*, the lobes assuming the form of a pear, and 
the horn representing the stalk. In a caterpillar I found 
amongst Mr. Francillon’s larve, the head is bilobed, 
with a very long recurving subcapitate subramose spine. 
In Brassolis Cassia, the head is armed with three occi- 
pital stout spines>. The larva of Limenitis ? Amphinome 
Latr. is crowned with a coronet of eight occipital stout 
acute spines, the intermediate ones being the longest¢ ; 
and that of Morpho Teucer has a similar coronet, con- 
sisting of only seven blunt rays, seemingly, rather than 
spines?. With regard to the articulation of the head 
with the trunk, it is generally by its whole diameter; but 
in some instances, only by a part of it. This is the case 
with one of a sphinx figured by Mad. Merian*; and I 
have another, probably belonging to the nocturnal Le- 
pidoptera‘. In both these, the head is vertical and trian- 
gular ; and in the latter (which is a remarkable creature, 
the tail itself being more like a head, and furnished with 
what resemble two prominent black eyes) the vertex of 
the triangle is considerably higher than the back of the 
animal, Whatever may be the clothing of the body, the 
head is usually naked. Sometimes, however, it is itself 
beset with very small simple spines, as in the butterfly 
of the mallow (Hesperia Malve); or with longer com-

© As the larva of L. Amphinome differs widely from these of L. 
Camilla, Sibylla, &c. the types of the genus, it ought to form a dis- 
tinct one: it agrees with that of Brassolis Cassie, except in having 
more occipital spines : they therefore probably belong to the same Fa- 
mily. (Comp. Mer. Surinam. ¢. vill. and xxxii.)

£ I purchased this singular caterpillar from the collection of the 
late Mr. Francillon, with his other exotic larve; but without any 
indication of the fly to which it belonged.
