line from the apex of the wing to the apex of the ciliae, and as in that 

 species, tlie ciliae are yellowish rather than yellowish brown, as Dr. 

 Clemens describes them. Dr. Clemens' statement that in splendoriferella 

 there is a black apical spot, with metallic scales, in its centre, also 

 seems to me misleading ; there is only the fan-shaped apical black spot 

 divided across its centre by a paler brown streak, at each end of which is 

 a minute speck of silvery scales, and there is the third one at the 

 beginning or handle of the fan-shaped spot — and this is true of all the 

 species. I have not been able to detect separate from the brown dorsal 

 patch what Dr. Clemens calls " a blackish brown hinder marginal line in 

 the ciliae "' in splcndoriferdla, unless by it is meant the brown band which 

 -crosses the fiin-shaped spot ; but by careful observation with a lens, two 

 such lines may be found in the dorsal brown patch, darker than the 

 surrounding portions, but which I have not been able to detect in 

 diospxrielhi. The basal portion of the wing is more silvery than in 

 splcudoriferclla, and the apical portion is much less golden, so that in this 

 species the dark brown and silvery hues prevail over the golden, while 

 Dr. Clemens was perhaps right in calling golden the ground color of the 

 apical part of the wing in splendoriferella. 



In Jui^landiella the apical part of the wing is more golden than in 

 diospyriella, but less so than in splendoriferella.. It has, like diospyriella, 

 the anterior dark margins of the two silvery streaks confluent, and the 

 silvery streaks are separated mjuglandiella as just described in diospyriella 

 But, as in splendoriferella, the golden costal patch sends oft' towards the 

 dorsal ciliae and to the little silver s])Ot which on that side margins the 

 fan>shaped spot, a short streak which is not cut oft" from the rest of the 

 golden patch by a process from the costal brown spot to the fan-shaped 

 spot, as we have seen is the case with diospyriella. The case of juglan- 

 diella, like that of diospyriella, is nearly oval, whilst that of splendoriferella 

 is rather trapezoidal. But juglandiella is but little smaller than 

 splendoriferella, whilst diospyriella is but little larger than salicifoliella 

 Some of the points of difference that I have mentioned are only brought 

 out by the use of the compound microscope. 



Considering the near relationship of the food plants (Walnut and 

 Hickory), it is strange that I have not sooner thought that juglandiella 

 may be lucifneUa Clem. It may be, though I have not been able to 

 recognize it in Dr. Clemens' description. Indeed, it seems to me that 

 Jucijlnella and A. ella are nearer to each other, though I have not been 

 able to recognize A. ella in Dr. Clemens" description of litcifliiella. I
