153 THE ENTOMOLOGIST. 



Leucania, Och., obsoleta, Hb. 



The type of this species is Hiibner's j&g. 233, which gives a 

 very incorrect idea of the form we get, and an equally incorrect 

 one of all Continental specimens I have seen. The anterior 

 wings are of a different shape to our ohsoleta, and it is highly 

 colom-ed. The row of dots parallel to the hind margin are, 

 however, distinctly marked. My first impression of the figure 

 was that the fore wing represented the var. punctalinea of 

 impura, but the hind wings are characteristic of ohsoleta, which 

 cannot be mistaken for those of any other species. Hiibner's 

 figure may have been an unusual form, but I have seen no 

 varieties. 



Leucania, Och., putrescens, Hb. 



The types of this species are Hiibner's (Geyer's) figs. 730 and 

 731. These, although presenting the general characteristic 

 markings of piutrescens, are so small compared with our British 

 form that they are hardly recognisable. I have seen no Conti- 

 nental specimens, but, if Hiibner's figures are a fair representation 

 of the species as it occurs on the Continent, our form is well 

 worthy of a distinct name. This would hardly seem to be so 

 from Guenee's remarks, * Noctuelles,' p. 80, where he writes, 

 " Bad as is the figure of Geyer, I believe decidedly that it really 

 is the type of this species, which it represents, and not, as I at 

 first thought, a variety." 



(I have dwelt on Hiibner's figures of these two species 

 because they represent the first described or figured types of 

 their respective species.) 



Leucania, Och., impudens, Hb. 



Hiibner's fig. 229 (by error 329) is the type of this species, 

 which may be described as follows : — Anterior wings of a pale 

 greyish colour, with no trace of reddish, thickly sprinkled with 

 black dots ; a dark but faint longitudinal shade runs just above 

 the inner margin, another between the upper branches of the 

 median nervure, and another near the apex, a black dot at the 

 end of discoidal cell ; hind wings very dark grey, no markings 

 whatever. Guenee, comparing the type with pudorina, says of
