Noctuidse. 

 4. Spadotis crinigera^ sp. n. (No. 11). 



Colour of primaries and thorax similar to >S'. ravida^ and 

 exhibiting the same slight variations of tint from brownish to 

 slaty grey, always as sericeous and sometimes more so than 

 in that species ; the markings on the primaries agree with 

 those of >S'. pyropliila, excepting that they are black, with 

 scarcely perceptibly paler borders : secondaries only differing 

 from 8. pyrophila in having the yellow line at the base of the 

 fringe sliarply defined and limited externally by an interrupted 

 dusky line ; abdomen greyish brown, the male with a very 

 large anal tuft of long stramineous hair. Under surface 

 shining white in the male, greyish in the female, with the 

 discoidal area of primaries greyish in both sexes ; internal 

 area shining brassy opaline i a slightly dentate-sinuate discal 

 grey stripe, abbreviated on the primaries : body below sandy 

 yellowish in the male, sordid white in the female, dusky in 

 front behind the palpi ; tarsi blackish, with pale bands at the 

 joints. Expanse of Avings 1 inch 8 lines to 2 inches 3 lines. 



Four specimens, in both sexes ; Mr. Blackburn says of them, 

 " I believe it to be identical with the Agrotis referred to in 

 your papers in E. M. M. vol. xv. p. 269, and vol. xvii. p. 7, 

 which was too much broken to be named, also with the insect 

 described by you as Spwlotis lucicolefis. How the number 

 * 12 ' (unless it be a misprint) got placed against the latter I 

 cannot conjecture, for the number H2 ' is marked off from my 

 note-book as non-existent, having been applied to a single 

 worn specimen of a Leucania, which further study satisfied 

 me was only dislocata, Walker." In this supposition 

 Mr. Blackburn is partly correct ; that is to say, this is the 

 supposed ^^ Agrotis ; " but it differs from my " 8pailotis luci- 

 colens,'''' which (with "/S. cremata^'') must be referred to 

 Agrotis^ in the simple instead of pectinated antennae of the 

 male : the species which must now stand as Agrotis lucicolens^ 

 although it possesses the general coloration and pattern of 

 SjKvlotis, is represented by a male specimen having strongly 

 pectinated antennae, as in ^. crassa of Europe, to which it is 

 probably most nearly allied. A. cremata also has the an- 

 tennae of the male exactly as in typical Agrotis^ notwith- 

 standing its Spcelotis-Wko, pattern. 



The specimen of A, lucicolens still has the No. " 12 " 

 attached to it ; so that it seems probable that this number 

 when detached from the Leucania was accidentally transferred 

 to the Agrotis. Of Sj>ailotis crinigera Mr. Blackburn says
