234 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



having been described as endemic. Approximately half the total number 

 are Phalaenidae; in fact, the Phalaenoidea (Phalaenidae plus Arctiidae 

 of this list) account for exactly half the total. Yet the really interesting 

 feature of the list is the absence of so many tropical groups both with and j 

 without strong flying tendencies. Although half the total are Phalaen- 

 oidea, the phalaenoid families Notodontidae, Lymantriidae, Syntomidae, 

 Pericopidae, Dioptidae, and the stronger flying Arctiidae* are absent. 

 Also absent are the Papilios and Danaidae among the butterflies, and 

 among the moths the whole Saturnoidea, Bombycoidea, Drepanoidea, 

 Uranioidea, Cossidae, Castniidae, and most of the "micro" families 

 (many of the species of which are not small). It seems truly strange that 

 so many Phalaenidae, big and small and of many diverse groups, have 

 reached these islands when so few other Lepidoptera have done so. 



The 6 species here recorded from the Galapagos Islands for the first 

 time are : 



Feltia annex a (Treit.) 



Peridroma margaritosa (Haw.) 



Peridroina (Peridroma) conwayij new species 



Prodenia dolichos (Fabr.) 



Prodenia eridania form normal linea (Fabr.) 



Zale sp. of viridans group 

 These also represent the first definite records of these 4 genera.
