fluence of the siipplj^ of food, or indicate any veiy accurate measure-

Prof. Riley seems to attach some importance to the fact that my re- 

 marks on the spotted fovxnoi Pronuoa occur on "the ver}^ first page" of 

 my paper in the Bulletin. I fail to see what difference it makes 

 whether they occur on the first or the last. Prof. Riley is certainlj' 

 familiar enough with the classification of the Tiveina to know that P. 

 yuccasella is the highest form treated of in that paper ; and that ar- 

 ranging the species sj-stematically, I began with the highest, Pronuha, 

 and ended with the lowest, Nepticula. 



Explanation oj the Figures. — Fig. 1 shows the position of the spots 

 in the Colorado species; fig. 2 sliows the position of the spots in Hypo- 

 nomeula dpunctella. 



The figures are not intended to show accurately either the form or 

 neuration of the wings, onlj- the position of the spots. 



As to the Colorado species, I find in my notes the following state- 

 ment in addition to what I have published in the Bulletin, as before 

 mentioned: "The vertex is somewhat roughened, the antennae are 

 not quite half so long as the wings, and have the apical half naked." 

 In Hyponomeuta, and 1 believe also in Pronuha, the apical half of the 

 antennffi is clothed with scales. I am not, however, certain as to this 

 about Proniiba, of which I have no specimen now in my collection, 

 and Prof. Riley makes no statement about it in his diagnosis of the 

 genus. Nor do I know that my note applies to all the specimens ex- 

 amined by me. If it does, and the antennse are clothed in Pronnba, 

 the species taken by me would seem to differ in this respect both from 

 that genus and from Hyponomeuta. In Hyponomeuta the awlennnd 

 are a little more than half as long as the wings, and the antennte of 

 Pronuba are said bj' Prof. Riley, in his diagnosis, to be not more than 

 half as long as the wings. In Hyponomeuta the head is, as in the 

 Colorado specimens, "somewhat roughened;" while in Pronuba, Prof. 

 Riley says it is " sparsely haired." 



ON THE DEFORMITIES OF SOME TENNESSEE 

 HELICES. 



By a. G. Wetherby. 



During the past season, while engaged in making collections on tiie 

 Cumberland table-land of Tennessee, various species of Helix were 

 found in the cliff" regions to exhibit wide variation from the normal 

 type. An instance of this may be found in the H. (Triodopsis) ap-
