210 Prof. Frey^ and some American Teneina. 



LilhocoUetis, except L.ornatelht, Cham.,andL. helianthemeUa, H. S., it 

 leaves the mine to pupate, as do most species of Gracilaria. Then, when 

 we come to the imago, the tuft on the vertex is much more like the long, 

 loose scales, which slightly roughen the head of some species of Gracila- 

 ria, than it is like the erect tuft of Litliocolletis. Dr. Clemens was 

 mistaken in the statement that it has no maxillary palpi ; they are dis- 

 tinct, though small, as they are in some small species of Gracilaria, 

 but both the maxillary and labial palpi differ in form and appearance 

 from the palpi of Lithoeolletis, being more like those of some small 

 Gracilaria. The form of the head is more like Gracilaria, and, above 

 all, the form and neuration of both the fore and hind wings are those 

 of a Gracilaria, and not at all those of Lithoeolletis. Hence, I think I 

 am right in placing it in Gracilaria, as generally received, though per- 

 haps not in Gracilaria as restricted by Dr. Clemens. Certainly it can 

 never be properly placed in Lithoeolletis. Where, then, is this wonder- 

 ful confusion which the Professor tells the American Micro-Lepidopter- 

 ists are in, and about which he gave his unfortunate head that terrible 

 cudgeling ? If it exists at all, it is only on the question whether the 

 name of this last species (there is no trouble about the insect) should 

 stand Parrectopa robiniella, Clem., or Gracilaria robinidla, Clem, — 

 Lithoeolletis gemmca, Frey, is frayed out. 



The only remaining species mentioned by Prof. Frey in this genus, 

 is L. cenigmatella, Frey, which seems to be not in all respects a 

 Lithoeolletis. I do not recognize any form known to me in this descrip- 

 tion-. 



The Professor then proceeds to the genus Tischeria, of which he thinks 

 that he bred five species : ten from oak leaves, and one each from the 

 apple, one from rubus (blackberry), and one from rose leaves. As to 

 these, all we can say is, that, as to the oak-feeding Tischeria, the less 

 said the better, until some one will study carefully the whole life 

 history of this group. There is more confusion already about this 

 group than about all the species of Gracilaria and Lithoeolletis in the 

 United States, although the described species do not amount to more 

 than one tithe of either of the other genera. We think it very proba- 

 ble that entomology would be better off to-day, if Dr. Clemens, I, and 

 Prof. Frey had entirely omitted all notice of the oak-feeding species of 

 Tischeria. As to the species bred from the apple, rubus and rose, I 

 believe that it is only one species, T. Malifoliella, Clem., under three 

 names ; the other two names, T. cenea, Frey, and T. roseticala, Frey, 

 being added for the same species when feeding on the rubus and the 

 rose. As early as 1871 (Can. Eut., vol. iii., p. 28), I mentioned the 

 fact that T. Malifoliella, Clem., fed on the blackberry (rnhns villosns)
