Family 1. EXAPATID.E. 



■lla maris amplnc, fc/'ni'uKe valde albreviuld' et acuminatfe. Antennie 

 crassiiiscuhe, pubescentcs vel dense ciliatiu. Haustellum breve, aut 

 nullum. Palpi labiales breves, aut longiuseuli ; palpi niaxillares de- 

 sunt. Larva IG pedibus instrueta ; tertio pari claviformi ; inter folia 

 victitat. 



Trings of the males of large size, of the females extremely abbreviated 

 and pointed. Antenu.e rather thick, pubescent or densely ciliated. 

 Tongue short or entirely wanting. Labial palpi short or moderately 

 long ; maxillary palpi undevch)ped. Larva; with sixteen legs, the third 

 pair club-shaped. This character does not appear cpiite universal in 

 this family ; it occurs both in Salicella and Fagella, but in I'JirjjgaueUa, 

 according to Mdme. Lienig's observations (Isis, 1810, p. 209), this 

 peculiarity is restricted to the young larvae of the males ; the adult 

 male larvas and the female larvae always having the third pair of legs 

 of the ordinary form, and the larv;e of Gelatella never have this peculiar 

 formation of the third pair of legs. 



This family contains three genera, consisting of foiu' species, 

 and no other European species are at present known. 



TJic larva; feed iu the siunnicr and autumn between united 

 leaves, and the perfect insects a])pear at the commencement of 

 winter (when C. rkri/>janel(a may frecpientl}- be observt'd on the 

 wing in the day-time), or early in the spring. 



The three genera may be readily distinguislied as follows : — 



Tongue none. 



Labial palpi of the J' very short. 1. I'-xai-aii;. 



Labial palpi porrected. '2. Dasystoma. 

 Tongue short. 



Labial palpi ascending; terminal joint smooth and pointed. 3.
