Head with appressed or rather rough hairs. Ocelli present. 

 Antennae \-\, gradually dilated from about middle to near 

 apex, thence rather pointed, terminating in a small hair-pencil. 

 Labial palpi moderately long, curved, ascending, terminal joint 

 short, pointed. Maxillary palpi rudimentary. Posterior tibiae 

 more or less rough-haired. Forewings : lb obsoletely furcate, 

 7 and 8 stalked. Hindwings 1 or over 1, elongate - ovate ; 5 

 absent, 6 and 7 tolerably parallel, 8 absent (probably absorbed 

 in costa). 



A rather considerable family, principally inhabiting the 

 Northern hemisphere. Imago with wings partially hyaline, 

 forewings elongate, narrow, somewhat dilated posteriorly, apex 

 obtuse ; hindwings elongate-ovate. The species are diurnal in 

 habit, Hying in hot sunshine ; their flight is usually rapid. 

 The supposed resemblance to II i/menoptera is probably in most 

 instances imaginary ; but Aegeria apiformis seems to be a true 

 mimic of the hornet ( Vcspa crabro), and some exotic species 

 arc faithful copies of hairy bees. 



Larva elongate, with 10 prologs ; feeding in wood of trees 

 or rootstocks of plants. Pupa with abdominal whorls of spines, 

 segments 8-11 free, in $ 12 also; situated within the larval 

 gallery. 



The first two genera may be taken as developments of the 

 third. The family is derived from forms of Plutellidae (allied 

 to Heliostibes) transitional between the Simaethis group and the 

 Gelechiadae.
