BRITISH LEPIDOPTERA.

 mattgoldgelb, mit vielen Scbuppen, sehr schmalen Federehen, und 

 feinen Haaren bedeckt. Die Unterfliigel, deren einer, q, efcwas 

 vorstehet, wie eine Vogelfeder. An den Randen heram, r, s, lauter 

 solche Haarformige, langstielichte, oben keulenformige, undgespaltene, 

 dicke beysammen gepnanzte Federn als Fig. 10. Wegen seiner 

 Kleinheit konnt'ich ihn ohne Verletzang nichfc genauer behandeln. 

 Mir war am meisten an dem Beweise gelegen, dass es erstlich eine, 

 aus einem Minirraupchen mit achtzehn hautigen Wulstfiissen, ganz 

 ungezweifelt gewiss ausgekomtnene Phalane war ; zweyfcens, dass sie 

 in Farben und Bildung der Glieder von andern Minirraupenmotten 

 ganz abwich. Und diesen Beweis hat mir die Natur, die Erfahrung, 

 und der Augenschein gegeben " (Goze, Naturforscher, xv., 1781, pp. 

 40-46). 



Imago. — Head bright orange-yellow, the long hairs covering the 

 base of antenna?, which appears to be black. Anterior wings 5 mm. ; 

 bronzy, tinged with purple on costa at base ; apex purplish-red ; cilia 

 dark grey at their bases, paler towards the tips. Posterior wings and 

 cilia dark grey. 



Comparison of N. anomalella with N. fletcheri. — Compared 

 with N. fletcheri, the fore-wings appear to be broader in N. anomalella, 

 the purple colour at the apex redder and extending over a greater 

 area, being produced markedly in some specimens for a short distance 

 along the costa towards the base. There is also in N. anomalella a 

 tendency to the development of a patch of pale cilia quite at the apex 

 of the fore-wings. The posterior wings and their cilia appear also to 

 be more uniformly dark grey. Besides these characters, the red-headed 

 N. anomalella is a distinctly larger insect than the black-headed A 7 . 

 fletcheri. 



Egg-laying. — The egg is laid on the under- surface of a rose-leaf, 

 close to the midrib, or (almost as frequently) against one of the large 

 lateral veins of the leaf. It forms a complete oval in outline, has a 

 perfectly transparent shell, with no trace of sculpturing ; one end of 

 the shell is, however, almost always yellowish in hue, the remainder 

 of the shell colourless. There is only a slight trace of iridescence, 

 even with a good light. In some instances the shell is packed almost 

 full of black frass, in other cases it is practically empty. 



Mine. — The mine is at first very fine, and discolours the leaf so 

 that the track is greenish, reddish or brownish at the sides (in dried 

 leaves, probably due to difference in the colour of the chlorophyll), 

 with the black frass scattered along the central part of the gallery. 

 The frass, however, soon becomes exceedingly dense, filling the whole 

 of the space mined, and causing the mine to appear as a wavy black 

 line, with a fine red (or brown) margin on either side. This first part 

 of the mine is about an inch in length, and contains about three or 

 four wavy curves in its course. The second part of the mine is much 

 wider, and altogether is perhaps an inch and a half in length ; the 

 larva now clears out a large part of the parenchyma on either side, 

 leaving a pale (greenish) margin on each side of the trass-line, the margin 

 gradually increasing in width as the larva progresses ; this paler area is 

 again bounded on either side with a narrow reddish (or brownish) 

 margin, whilst the frass still forms a dense central wavy line. At the 

 termination of the mine the larva clears out an area about a quarter of
