SOLAR ECLIPSE, MAY 6, 1883. 93 



latter collectiou contained thirteen specimens, and throngh the kindness of my colleague. 

 Professor Owen, of tbe University of Wisconsin, it was submitted to Dr. Hermann Strecker, 

 of Heading, Pennsylvania. 



Dr. Strecker was prevented from making a careful study of tiie collection, and returned it 

 with the identification of five specimens, viz : 



1 Utethesia palchella, L. 



4 Diademu bolina, 3 5,19. 



One of the latter (a male) and the other eight specimens were sent by me to Dr. Arthur (K 

 Butler, assistant keeper of the zoological department of the British Museum. The remaining 

 four were presented to Professor Owen's collection. 



Dr. Butler kindly undertook the identification of the nine specimens sent him, and his 

 report on the subject follows. These specimens are now in the collectiou of the British Museum. 



It will be seen that Dr. Streckbr's Diadema bolina has been made a new species by Dr. 

 Butler, who has also found in this small collection three other new species, one representing a 

 new genus. 



I desire to express here the thanks of the expedition to these gentlemen for their kindly 

 interest, and especially to Dr. Butler for his full report, which follows : 



THE LEPIDOPIERA COLLECTED ISY HERR I'ALISA AT CAROLINE ISLAND IN IIAT, 1883. 



By Arthur G. Butlkr, assistant keeper of the zoological tlepartmeiit, British Museum. 



"The collection contains one butterfly of the family Nymplmlidm ; the moths are represented 

 by a new species of Maeroglossa, three species of NocUue, and sexes of one species of Pyrales. 



butterflies. 



Nymphalidji;. 



Hypolimnas Roldeni. sp. n.'(No. Gl). 



<J wings above, velvety, blackish-piceous, with the sinuations of the cilia white ; primaries 

 with a large, irregular, oblique ])atch of glossy ultramarine blue, inclosing an oblique oval lilac 

 patch, irrorated with white scales immediately beyond the cell ; an oblique, unequally trifid, 

 subapical spot, the two upper divisions of which are snow-white, aiid the inferior division ultra- 

 marine, irrorated with lilac; secondaries with a large subquadrate central patch of glossy ultra- 

 marine, its inner edge straight, limited by the first median branch, its other edges undulated 

 between each pair of veins ; this patch incloses a small central aggregation of lilac scales ; 

 abdominal area purplish brown, with iiale sandy-brown inner edge ; body blackish ; head and 

 palpi white spotted ; antennal club tipped with bright cupreous ; under surface very similar to 

 that of H. rarite of Eschscholtz, which we have from Korth Australia and the EUice Islands, but 

 wanting the white band across the secondaries; the subniarginal lunate spots are also bluer, and 

 the apical area of the primaries is redder; it also differs from H. otaheitai of Felder in the same 

 characters and its greatly superior size ; expanse of wings, 75 millimeters. 



The genus Hypolimnas is a difiicnlt one, chiefly owing to the great similarity of the males. 

 This difticulty is, however, increased in certain islands by the apparently variable tendencies of 

 the females, more particularly in the ground-color of the wings. How far these modifications are 

 constant to locality within the island can only be ascertained by careful breeding ; but as regards 

 forms from different islands there can be no doubt that they are locally separable.
