Famitry I. EXAPATIDA‘ 
Ale maris ample, femine valde abbreviate et acuminate. Antenne 
crassiuscule, pubescentes vel dense ciliate. Haustellum breve, aut 
nullum. Palpi labiales breves, aut longiusculi; palpi maxillares de- 
sunt. Larva 16 pedibus instructa; tertio pari claviformi; inter folia 
victitat. 
Wings of the males of large size, of the females extremely abbreviated 
and pointed. Antenne rather thick, pubescent or densely ciliated. 
Tongue short or entirely wanting. Labial palpi short or moderately 
~ long; maxillary palpi undeveloped. Larvae with sixteen legs, the third 
pair club-shaped. ‘This character does not appear quite universal in 
this family ; it occurs both in Salicella and Fagella, but in Phryganella, 
according to Mdme. Lienig’s observations (Isis, 1846, p. 269), this 
peculiarity is restricted to the young larvee of the males; the adult 
male larvee and the female larvee always having the third pair of legs 
of the ordinary form, and the larvee of Gelatel/a never have this peculiar 
formation of the third pair of legs. 
This family contains three genera, consisting of four species, 
and no other European species are at present known. 
The larvae feed in the summer and autumn between united 
leaves, and the perfect insects appear at the commencement of 
winter (when C. Phryganella may frequently be observed on the 
wing in the day-time), or early in the spring. 
The three genera may be readily distinguished as follows :— 
Tongue none. 
Labial palpi of the g very short. 1. Exaparn. 
Labial palpi porrected. 2. DasysToma. 
Tongue short. 
Labial palpi ascending; terminal joint smooth and pointed. 3. 
CHIMABACCHE.
