MACROLEPIDOPTHRA [SUPPLE MENTIS ''<y'-'^., 



■ c. 



By Edward Meyrick, B.A., F.Z.S., F.E.S. 



Since the publication of my main paper, a considerable further collection whs 

 made by Mr Perkins, almost wholly in the island of Oahu, which had previously received 

 little attention from him ; and the results of an examination of this additional material 

 are now^ shown, together with the correction of some previous errors, and the inclusion 

 of two or three forms described elsewhere in the meantime. 



Four genera and eighteen species are thus added to the list, and several species 

 previously inadequately known have now been illustrated by extensive series. The 

 general results indicated in the introductory portion of my main paper are however 

 practically unaffected. 



Two of the genera, NesocJilide and Aci-odrcpanis, are offshoots of Scotorythra, 

 from which they do not greatly differ ; one, Hypcrcctis, is an isolated form of Pyraustidae, 

 of (at present) doubtful affinity and origin ; and the fourth, Evergestis, is a common 

 Indo-Malayan insect of undoubtedly artificial introduction. 



Besides the species included in the above additional genera, there are added species 

 o{ Agrotis (i), Hypeuodes (i), Plnsia (i), Scotorythra (5), Omiodes (i), PJilyctacnia (2), 

 Mestolobes (i), and Scoparia (3). These are much what might have been anticipated, 

 with the exception of the Piusia, which is a remarkable form, and the first endemic 

 species of the genus, which it has the effect of removing from my category [a) to {b), 

 placing it on the same footing as l^aiiessa. 



Owing to the intermediate position of Oahu, which encourages a community of 

 fauna with each of the two extremes, Hawaii and Kauai, the investigation of this 

 island has somewhat reduced the percentage of endemic species confined to a single 

 island, which now stands at about 61 per cent, instead of 67.
