thorax is wider, IJ mill, in specimens measured, and relatively less constricted 

 anteriorly. The pectination of the antenna; is larger, and each leaflet longer. All 

 these characters are conspicuous, but I fail to see others, except the general colour 

 of the thorax, which is castaneous rather than piceous. 



The three males I possess have been captured in the plains 

 between Fujisan and Tokohama, but I have not taken it myself. I am 

 much indebted to Mr. Ota, of Tokio, for a very fine example.

Occurrence of Stigmonota pallifrontana, Z., in England. — While looking over 

 my series of <S. iniernana, I lately became aware that one of the ? specimens 

 differed from the rest. The insect in question I found, on referring to my notes, 

 had been sent me eight years ago by Mr. W. Thompson, of Stoney Stratford. 

 Indeed, it was the first example of internana that I possessed, and as such was 

 placed at the head of my series. Accordingly, I wrote to Mr. Thompson, and, in 

 answer to my queries as to his captures of internatia, was informed that he only took 

 one or two a season, and then always by sweeping flowers of Heracleum sphondylium, 

 but that he had once taken a few in quite another place, upon a heath. Ho kindly 

 sent me three more to look at, 2 ? and 1 $ , when I at once saw that the second 

 supposed ? was another S of the same species as my original type. I expect that 

 the insects Mr. Thompson captures on the heath are the real internana, while those 

 he sweeps from the iZerac?e«j« flowers belong to the species new to \xs, pallifrontana, 

 Z., which may be thus described : — F. w., dull blackish-Srown ; on the inner margin 

 a curved yellowish- white blotch, containing a single dark brown curved line along 

 its centre ; on the costa are two yellowish-white spots before, and six beyond, the 

 middle — not eight, as is generally the case, — the two nearest the apex being single, 

 not geminated ; face and palpi yellowish- white. From the 5th and 6th costal spots, 

 reckoning from the apex, a fine blueish line curves across the wing to the hind- 

 margin, slightly beyond the anal angle ; along the lower edge of the hind-margin is an 

 indistinctly marked coppery line. H. w., dull blackish-brown, alike in both sexes. 

 Thorax, patagia, and abdomen all blackish-brown. 



From its nearest allies, composlteUa, F., and internana, Gn., it may be thus dis- 

 tinguished :^The ground colour of the wings is distinctly brownish, not so black as 

 in the other two. The markings are dull yellowish-tvhite, insiead of lustrous silvery. 

 The hind-wings of both sexes are alike brown, whereas in the $ s of both the other 

 species the hind-wings are dark grey, and in the S s whitish towards the base. The 

 face and palpi are clear yellowish-white, whence the name. 



Moreover, in both its allies the lustrous line is obtusely angulated in the middle 

 of the wing, and reaches the anal angle itself as a broadish, pale silvery, perpendi- 

 cular blotch. Heinemann, p. 185, says that "each division of the blotch on the 

 inner margin sometimes bears traces of a further sub-dividing line, in wliich cases 

 it becomes diflicult to distinguish them from those ? specimens of compositella in 

 which the dark lines of the pale blotch are less distinctly marked." In the speci- 

 mens of pallifrontana which have come under my notice, I have observed nothing of , 

 this (nor, indeed, are such examples of compositella, as he here alludes to, very 

 common with us).
