322 Mr. A. G. Butler on Nocturnal Lepidoptera 



further : — " This insect is extremely common all over the 

 Hawaiian archipelago, as I have found out since I penned the 

 note from which you give extract calling it rare. I should 

 say it is periodical in occurrence. I have taken it at all 

 seasons of the year ; but sometimes hardly a specimen is to 

 be seen for months, then it swarms suddenly. At a place 

 called Kawaihae, on the island Hawaii, in February 1879, I 

 observed it literally in thousands round a lighthouse, evidently 

 attracted by the lamps. The unset specimen (type of the male) 

 was taken there ; the largest specimen (type of the female) is 

 from Maui, the other two from Honolulu. It does not usually 

 occur much above sea-level, and does not thrust itself into 

 notice much unless looked for about or soon after dusk, so is 

 easily passed over." 



With regard to Agrotis {"SjKelotis ") cremata, Mr. Black- 

 burn says, " I think there is a mistake somewhere in the 

 mention of Oahu as a locality for this species. I am only 

 conscious of having had three specimens altogether, two of 

 which I sent you in separate consignments. They were all 

 bred from pupge obtained in September 1876 in the Maui 

 sand-hills. If I wrote No. 10 against any insect with "Oahu" 

 as its locality it was a slip of the pen ; nor do I even think it 

 decidedly probable that the species occurs on Oahu, as that 

 island has no region of sand-hills ; and, moreover, Maui seems 

 to contain many other species peculiar to it, many more, so 

 far as my experience goes, than any other of the islands." 



Apameidse.

(J. Allied to A. unanimis^ but with the coloration of a 

 Graphiphora. Primaries shining laky brown, mottled with 

 testaceous towards the base and along the costal border ; costal 

 margin spotted regularly with black ; basal area crossed by 

 oblique interrupted slightly zigzag black lines, which appear 

 to be continuous with the first two pairs of black costal spots ; 

 four ill-defined, reversed, oblique, dentate-sinuated black lines, 

 the first, third, and fourth attached to minute whitish points ; 

 the first line (which runs from the "orbicular" to the inner 

 margin) very indistinct, the last line limiting the external 

 border, which is dusky ; a discal series of black dots j an 

 oblique subapical costal black dash ; a marginal series of 

 small lunate black spots, followed by a testaceous marginal 

 line ; base of fringe dark brown, remainder of fringe red- 

 brown ; orbicular and reniform spots whitish, with black-
