C88.) 
considered there could be no doubt that the families possessing 
incomplete pupe were allied together, and were probably 
a more ancient form; the probability of such a special and 
peculiar set of characters being separately reached by diffe- 
rent families being very small. The larval characters, 
moreover, of these same families separated them in almost 
every instance decidedly from the true Macros, and associated 
them with other families of the incomplete group. Dr. Chap- 
man further remarked that three families of the Incomplete 
were suited as larve for exposed existence; all the rest 
were concealed feeders, living either between leaves, in the 
tissues of plants, or were leaf-miners, &c. These three families 
were Zygena, Limacodes, and Micropteryx (calthella), of all 
which the larve are slug-like in form and movement, and 
possess very retractile heads. Tortrix formed a large and 
very uniform section of the Incomplete, and Cossus was held 
to possess in all its stages characters that did not admit of 
any describable difference between it and the Tortrices. Sesta 
occupied a position rather nearer Vinca; whilst Hepialus and 
Zeuzera presented characters showing no very distant re- 
lationship to lower forms, such as the dAdelide. Certain 
families of Tineina appeared to belong to the first group ; 
Obtecte and Gelechide were held to be true Pyralidina. It was 
shown that many Incomplete that had no maxillary palpi (6- 
jointed) in the imago, had them well developed in the pupa. 
A definition of Incomplete as possessing at least some trace 
of 6-jointed maxillary palpi in the pupa, and of Obtecte as 
without them, was suggested as in the main correct. It was 
also shown that the Incomplete possessed a dorsal plate in 
the pupa, very distinct on dehiscence, described as prothoracic, 
but possibly cephalic, and wanting in Obtecte, which carried 
with it the glazed eye (true eye?) covers on dehiscence. 
The prolegs of Incomplete were also referred to. Pterophorus, 
though exceptional in having a fixed pupa, was shown to 
belong to Incomplete, whilst Alucita belonged to Obtecte. 
Several other similar removals of genera were noted, and 
others would no doubt appear as the subject was worked 
out, several such removals having of late years been made 
on other grounds, and confirmed by the larval and pupal
