rather than the other. L. straminea differs chiefly in 

 the generally more prominent pale longitudinal streak 

 above the median vein of the primaries, and the better- 

 deiined black or dark markings. Not having bred both 

 from the egg, I keep them separate in the collection. 



The L. juncicola of Walker is not the species so named 

 by M. Guenee, but is the L. adjusta of Grote. The true 

 L. juncicola seems to be very closely allied to, if distinct 

 from, L. scirpicola. 



In the Index to ' Illustrations of Typical Lepidoptera- 

 Heterocera,' I inadvertently placed L.griscifascia, Moore, 

 as a synonym of L. commoides ; it really is a dark form 

 of L. percisa (Proc. Zool. Soc, 1888, p. 410). 



The following is a very variable species, which has 

 received many names : — 



18. Leucania unipuncta. 

 Noctua unipuncta^ Haworth, Lep. Brit., p. 174, n. 37 



(1810). 

 Typical form. United States, Chili, New Zealand, 

 Azores. Coll. B. M. 



This is a large reddish form of the species in which 

 the white dot on the primaries is very prominent. I have 

 seen no undoubted European examples of the species, 

 and the few specimens which may have been obtained 

 were probably accidentally imported. 



Yar. saccharirora. 

 Leucania saccharirora, Butler, Trans. Ent. Soc. Lond., 



1882, p. 115. 

 Chili, India, and New Zealand. Coll. B. M. 

 Smaller than the typical form, and of a brighter red- 

 dish colour ; the white spot obsolete. 



Var. antica. 

 Leucania antica, Walker, Lep. Het., ix., j), 100, n 52 



(1852).
