Genus 17. GIACLA. 

 The specimens under this name are mutiiated, and in some 

 characters, such as the deeply pectinated antennas and the ocellated 

 wings, the genus much resembles the Saturniidee, but a further ex- 

 amination proves it to have more affinity to the Noctuites, and it is 

 therefore transferred to that tribe.
