CHALCOSIID^E. 7 1 



hind border ; under side yellow, pale reddish towards the tips, 

 and with two black spots, the one nearer the base much 

 smaller than the other. Hind-wings yellow. Legs white, 

 femora and tibiae striped with white. Length of the body, 7 

 lines; of the wings, 22 lines." 



"North America (?)" 



" ' Taken on the door of the church at Horseleydown by 

 Mr. Bydder.'" 



The specimen above described is in the British Museum. 

 It is undoubtedly an accidentally introduced species, and may 

 be known from the other species of the genus by the absence 

 of any dark border to the yellow hind-wings. 



FAMILY VIII. CHALCOSIID^E. 



Egg. Not described. 



Larva. Tuberculated, with hairs springing from the 

 tubercles. 



Pupa. Enclosed in a dense cocoon. 



Imago. Measuring four inches or under in expanse ; body 

 rather short and slender ; antennae pectinated, especially in 

 the males ; wings generally broad, rounded, and entire, never 

 dentated, and rarely tailed, brightly coloured; cells closed, 

 and bisected by a nervure ; fore-wings usually with two sub- 

 median nervures, and hind-wings with three. 



This is a Family of moderate extent, peculiarly characteristic 

 of the Indo-Malayan Region, though a few species are found 

 in other parts of the world, Europe, North America, and 

 Australia (?) excepted. They are day-flying Moths, and are 

 perhaps specially protected, as is the case with so many 

 brightly-coloured insects; nevertheless, several species mimic 

 DanaincB of the Euplcea group very exactly. Several hand- 

 some species are figured in this volume.
