of small birds. .S'. ajjicel/n mid -S'. Pijrclld appenr in the first 

 biirsi of spring-, and are indelibly associated in the niiiul of the 

 collectors with those few uarui days at the end of Ajjril, "too 

 briu'ht to last." The ofher species do not appear till considerably 

 later; ])robably all, with the exception of «S'. apicella, arc donble- 

 broodcd. The larvtc of this genus are long and slender (espe- 

 cially anteriorly), with sixteen feel, and reside singly in webs on 

 the ii})per surface of the leaves of hawthorn, apple, pear, birch, 

 etc. They are easily frightened from their place of abode, and 

 readily descend to the ground l)y their silken thrcnds; when full- 

 fed they spin rather dense cocoons of very line white silk. Tlie 

 11 ve British species are all rather closely allied.
