184 ECNOMIDEA PITHECIUM. 



sable to assign it a new generic name, as has been 

 done above. Altogether only three of these curious 

 moths have fallen under our observation, and they 

 have so many points in common, that they may be 

 all included, at least provisionally, in the present 

 genus. The perfect insects are in no way remark- 

 able, but the caterpillars are furnished with long 

 lateral appendages, commonly curved backwards, 

 and so disposed as to take away all resemblance to 

 a lepidopterous larva. So much is this the case, 

 that Madame Merian, speaking of the one she has 

 figured, says that she found this rare animal on a 

 citron, and although it was entirely different from a 

 caterpillar, it produced a very pretty moth. Her 

 delineation was the first that appeared of one of 

 these caterpillars, and it seems to have attracted so 

 little attention, that we are not aware that even a 

 specific name has been given to it. Stoll figured ano- 

 ther, which he found to produce the moth described 

 by Cramer under the name of Phal. (Bombyx) 

 Hipparchia (pi. 185, fig. D). The third, which has 

 been engraved on the accompanying plate, was 

 figured by Abbot and Smith in their joint work on 

 the Lepidoptera of Georgia. 



All these caterpillars are rather of small size; 

 have the head minute and retractile as in Lima- 

 codes; the body somewhat flat, and on each side 

 are three long projecting appendages covered with 

 hair, having a small fleshy protuberance between 

 them terminating in a hair ; and there are two other 

 projecting pieces, of intermediate size, behind the
