170 CARADRININA 



3, 4, 5 approximated at base, 6 and 7 stalked or approximated, 

 8 connected with cell before middle. 



This family has its main development in the Indo-Malayan, 

 African, and Australian regions, where the genera and species 

 are numerous ; elsewhere it is but poorly represented, and is 

 absent from New Zealand. It originates from the Psychidae, 

 and is in fact very closely connected with that family. The 

 markings of the fore wings are often obsolete ; the reniform 

 spot is represented by a curved discal mark. 



Ovum spheroidal, smooth. Larva more or less hairy, often 

 with characteristic dense compact dorsal tufts on some segments ; 

 the hairs are sometimes poisonous, causing irritation or painful 

 inflammation, hence the larvae are usually uneatable. Pupa 

 sometimes rather hairy, in a cocoon above ground. 



Besides the following, Laria l-nigrum, Mull, (v-nigrum, F.), 

 has been included in the British lists, but probably through an 

 error of locality, the record being very ancient.
