early stages of some Trinidad Butterflies. 227 



brown protuberances projecting forward with a few small iuler- 

 mediate brown ones. From these rise some fine whitish hairs. A 

 fringe of similar hairs surrounds the body of the larva. A very- 

 peculiar and remarkable feature is the anal segment, which has 

 a sort of bony whitish scale flat and shining and divided by a black 

 line ; immediately in front of this are two brown wart-like humps 

 lighter in the centre. 



Habits. The larva feeds from the inside of a rolled cocoa leaf ; 

 the young and tender leaves being chosen. The larva is myme- 

 cophilous and lives surrounded by ants within the rolled-up leaf. 

 The ants evidently protect the larva and use it as an ant-cow is 

 used. The wart-like portions on the anal segment are tickled and 

 an exudation ensues which the ants are eager to obtain. When I 

 removed a larva the ants made a great fuss. They smell very 

 strongly of formic acid and are very active and build 2)aper nests 

 among the leaves. They frequently run over the larva, which does 

 not take any apparent notice of the proceeding. 



Pupa. Attached by the tail with a girth round the centre as in 

 the Theclid species. 



Theopefoliorum, Bates. (PL XVIII, fig. 2.) 

 Larva. Yery similar to Theope eudocia and lives on the same 

 plant under the same conditions. 



Nymphidium molpc. 



Larva. Head small and hairy. Abdomen flat slug-shaped very 

 similar in shape and habits to the two preceding Theope species. 

 A pair of horn-like protuberances take the place of the club-like 

 ones in the foregoing. Before pupating the body turns brownish. 

 The anal segment is similar to the Theope larvte and there are 

 large ants that attend and milk the larvise. These ants are solitary, 

 are armed with a powerful pair of jaws, and when I went to remove 

 them from the backs of the larvie, they snapped violently at the 

 piece of wood I was holding. A pair of larvje are generally found 

 on each plant and are to be obtained chiefly on the low-growing 

 Cassia plants, chiefly through the dry season, though some are to 

 be found at all times. 



Fupa. Very much like a piece of wood. 



Mcchanitis veritahilis, Butl. 



Ovuyn. Pure white with about thirteen longitudinal ridges, spindle- 

 shaped. The micropyle appearing as a small flattened area at the 

 apex. The eggs are laid regularly in batches, but each egg is quite
