80 * VARIETIES OF NOCTUJE 



the * fanfeet ' in the males, and the difference in colour from any 

 of its allies. Our British specimens, or at least those from the South 

 of England offer a slight variation in the ground colour, some being 

 of a dark shade compared with others. The markings are variable 

 in intensity and distinctness, and they also vary somewhat in 

 shape. The hind wings of some specimens are very much shaded 

 with darker on the outer margin, especially towards the centre. There 

 is a distinct sexual difference in the form of the abdomen, but the 

 sexes vary much in size, some specimens of either sex being above, 

 and others below the average size. 



a. var. pectitalis, Hb. The darker form of this species is known 

 as pectitalis, Hb. The description I made of Hubner's figure is as 

 follows : " Anterior wings grey with a slight slaty tinge ; the basal 

 line very much bent ; the reniforin (a linear spot only) and the elbowed 

 line brownish, the subterminal yellowish with a yellowish marginal 

 line just inside the fringe. The hind wings paler grey, whitish along 

 the upper edge where it is in contact with the fore wing with two 

 whitish transverse lines edged with dark grey " (' Sammlung europ. 

 Schmet.' (Pyrales), fig. 122). 



TABLE SHOWING THE CHIEF CHARACTERS OF THE SPECIES IN THE 

 SUB-CLASS Deltoides. 



To enable British collectors to distinguish readily the species in 

 the Deltoides, the following table is appended : 



I. HYPENIDJE 



a. Madopa salicalis Slaty-grey ground colour trans- 



verse lines reddish edged with yellow. 



b. Hypena proboscidalis Large size brown colour inner 



line not indented on the fold. 



c. Hypena rostralis Kaised tufts of scales on disc of 



wing inner line sharply indented on the fold 

 almost straight elbowed line. 



d. Hypena obsitalis Kaised tufts of scales on disc of wing 



basal (inner) line not so sharply angulated on 

 the fold distinctly angulated elbowed line sub- 

 terminal line composed of pale dots. 



c. Uomolocha fontis Large reddish-brown or chocolate- 

 brown costal patch at base and centre of wing inner 

 margin whitish. 



/. Hypenodes costcestrigalis With a dark costal patch 

 before the elbowed line. 



(j. Hypenodes albistrigatis No dark costal blotch before 

 the elbowed line the elbowed line conspicuously 

 edged with white. 



//. Tholmiges turfosalis Of exceedingly small size for this 

 sub-class.
