Q [June, 



" One finds varieties of this, as of the following specic=3 (hi/peri- 

 " cmta), in which the ground colour of the anterior wings is of a golden 

 "colour, others in which it is of a dark brown-grey. Sometimes also 

 " the shield and the white streaks are absent. These specimens can 

 " hardly he distinguished from hypericana. * * * 



" The rather scarce imago should fly in July ; its larva should 

 " occur on Hypericum quadranrjulum " (I !). 



Vol. X, part 3, p. 110, he adds the following note on Holienwar- 

 thiana — "It runs through, in a number of varieties, eveiy modification 

 " from light cinnamon-brown and red-brown to pale whitish yellow- 

 " grey. It is often confounded with hypericana, and the cinnamon 

 " coloured varieties of Hohemoarthiana are referred to that specie^. 

 " * * * A closer acquaintance with the true ^o7^e?»6','?r/7?i'«?w has 

 " shown me that the white marginal shield contains not ihree longitu- 

 " dinal streaks, but at most only ttoo, composed of spots, and rarely the 

 "traces of a third." 



Of hypericana he says — " Specimens which I previously had re- 

 " ferred to this belong to the previous species {Hohemoarthiana^ : 

 " hypericana has in the marginal shield three, not composed of dots, 

 " distinct black longitudinal streaks. This character separates it most 

 " certainly from Hohenwarthiana.'" 



Now, from all this it seems evident that Treitschke's Holienwar- 

 thiana was either a jumble of distinct species (possibly including the 

 present and its allies), or else a species not known in this country at 

 all, and very distinct from ours, and to this the passages in his descrip- 

 tion which I have italicised seem to point. There can be very little 

 risk of confusing either of the species of this group with liypericana, 

 neither does either of them show any preference for Hypericum qua- 

 drangulum ; indeed, they nearly always occur in chalky or sandy fields, 

 rather than in the marshy places and ditch pides in which the Hyperi- 

 cum loves to grow. Moreover, JLxxb'iiev'' ^ pupillana is of a dull yellowish- 

 brown, paler at the base, with leaden-silveiy markings, but far too 

 broad in the iving for either of the present species. Therefore, it 

 appears clear that we may safely drop the name Hohcnwartldana 

 altogether. 



But Haworth's diagnosis of Tort. ScopoJiana (p. 45G) — "Wings 

 " reddish-fuscous, with the ordinary median spot ashy, and another 

 " 7nore ohscure in the anal angle " alone suffices absolutely to indicate 

 this species, and the descriptions of its vai'ieties which follow confirms 

 it. Stephens copies the name and the description with very little al- 

 teration, while Wood (fig. 988) gives a most accurate representation of
