STATES OF INSECTS. 115 



two lobes of the head, I am informed, terminate behind in 

 two horns ; as they do likewise in the brilliant Morpho 

 Menelaus a , the lobes assuming the form of a pear, and 

 the horn representing the stalk. In a caterpillar I found 

 amongst Mr. Francillon's larvae, the head is bilobed, 

 with a very long recurving subcapitate subramose spine. 

 In Satyrus Cassia ; the head is armed with three occipital 

 stout spines b . The larva of Nymphalis Amphinome Latr. 

 (Limenitis F.) is crowned with a coronet of eight occipi- 

 tal stout acute spines, the intermediate ones being the 

 longest c ; and that of Morpho Teucer has a similar coro- 

 net, consisting of only seven blunt rays, seemingly, rather 

 than spines d . With regard to the articulation of the 

 head with the trunk, it is generally by its 'whole diame- 

 ter ; but in some instances, only by a part of it. This is 

 the case with one of a sphinx figured by Mad. Merian e ; 

 and I have another, probably belonging to the nocturnal 

 Lepidoptera [Phalccna L.) f . In both these, the head is 

 vertical and triangular ; and in the latter (which is a re- 

 markable 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 but- 

 terfly of the mallow (Hesperia Malvce) ; or with longer 

 compound ones, such as are found on the rest of the body.

f I purchased this singular caterpillar from the collection of the 

 late Mr. Francillon, with his other exotic larvae; but without any 

 indication of the fly to which it belonged.
