﻿390 LEPIDOPTERA 



This case of resemblance is of the most noteworthy character, 

 for an appendage of this kind in a Lepidopterous Insect is 

 without parallel, and is almost equivalent to the production of 

 a new structure. An interesting feature of the case is that 

 Ichneumonidae do not sting, and there is no evident reason why 

 the enemies of the moth should be particularly afraid of an 

 ovipositor. 



The larvae appear to be in form somewhat like those of 

 Zygaenidae ; but with the same sort of remarkable clothing, in 

 the form of tufts and brushes, that we find in Lymantriidae. A

cocoon is formed. In Britain no member of this family is to 

 be met with, but Naclia ancilla may formerly have been a 

 native ; Syntomis jyhegea has occurred here ; probably an escaped 

 example that had been introduced in one of its earlier stages. 



Fam. 16. Zygaenidae (BwrTiet-Moths). — This family is one 

 about the limits and characters of which much difference of 

 opinion prevails. As exemplified by our Burnet -moths it is 

 characterised (in addition to the points given in the table) by 

 the peculiar, flexible antennae ; these are a little thicker before 

 the tip, but are curved and pointed at the extremity, and without 

 pectinations in the male. There is an elongate proboscis ; 

 bladder-like organs at the sides of the first abdominal segment 

 are not present. The pupa is softer than is usual in the Macro- 

 lepidoptera, and the parts are less firmly fixed together, so that 

 unusual mobility exists ; six of the intersegmental membranes
