natural affinities of the family j^geriidcB. 123 



by Mr. Stainton, and find that the following are the only 

 differences : — 



j^geriidcB. — LarvjB with 16 feet, internal feeders. 



Pi/r allies . — Larvffi frequently (if not always) with 16 

 feet, either internal feeders or rolled up in leaves. 



Gelechiidce. — Larvge with 16 feet, either internal feeders 

 or betAvecn leaves. 



Thus it is clear that some at least of the species in each 

 of the three groups agree in the number of their feet and 

 their habits. 



The charactei'S of the A^geriidcB reproduced in the 

 Pyrales are as follows : — 



The long-spined posterior legs in the whole family. 



The general form and ornamentation of the body in 

 Glyplwdes doles challii, several species of Vitessa, the 

 genus Azochis from South America, and even in the 

 common Botys urticaiis of Europe. 



The terminal anal tuft in Phakellura. 



The narrow anterior mngs in the Cingalese genus 

 lluryia. 



The transparent wings with black veins, in Erilusa and 

 several other genera ; but the Pearl-moths are, for the 

 most part, semi-transparent. 



The long anal sheath of Acridura gryllina (fig. 6) is 

 reproduced in various species of Botys, notably in B. con- 

 cordalis from the Amazons, B. admixtalis from Ceylon, 

 B. damasalis from China, as also in Platamonia stenosoma 

 of Felder (Reise der Nov. Lep. pi. cxxxiv. fig. 16) from 

 the Viti Islands (fig. 12). 



The densely-hairy second joint to the antennae of Acri- 

 dura metallica, of Tincegeria and Arauzona, is found also 

 in Omphalocera and Piletocera of Lederer's Monograph 

 (Wien. Ent. Monatschr. VII.), and occurs m a modified 

 form in the antennas of Desmia funeralis and Zehronia 

 jaguaralis. (Cf figs. 5, 9, 13, 18, with 10 and 11.) 



The remarkable antennfe of Tarsa bomhyciformis (fig. 

 16), in which the pectinations are fringed with stiff hair 

 below and terminate in strong curved spines, are almost 

 reproduced in the European Eurrhypis pertusalis, which, 

 however, differs in that the pectinations taper to a point 

 and terminate, not in spines, but in five or six stiff-ciu-ved 

 bristles (fig. 15). In Titer sana acuta (which is certainly 

 a Pyrale), although the antennas are somewhat compressed, 

 the pectinations taper less than in Eurrhypis, but only 

 terminate in a single rigid bristle (fig. 14).
