granules of somewhat unequal size. After the last molt the specific color- 

 ational characters definitely appear, and the sets are nearly obliterated. 



The coloration is uniform green Avith certain yellow lines, evidently 

 adapted to escape observation. 



The larva is a typical Eucleid, not highly specialized, yet without 

 any very generalized characters. The peculiar structure and arrange- 

 ment of the subdorsal setse in stage I cannot be congenital in our view,* 

 but may be some special adaptation to this stage, in which the larva does 

 not feed. Later the primitive tubercles appear as reduced and finally 

 rudimentary structures. The spiracles are in line, normal. The de- 

 pressed areas, characteristic of the family, are in a state of moderate 

 development, while the skin granulation is also intermediete between 

 such extremes as Sibine and Eulimacodes. 



Affinities, Habits, Etc. 



This species is related to the European Apoda avellana {Limacodes 

 testudo) in a close degree. The larvc^ seem not to differ, to judge by 

 Dr. Chapman's description and by a well prepared specimen from 

 Staudinger and Haas. The moths only differ in that y-inversa is usu- 

 ally less suffused with brown, while avellana is rather smaller, more like 

 our A. rectilinea. 



We may regard this species as derived from a former circumpolar 

 fauna, whose near allies are not now found in tropical South America, 



* These structures appear in Tortricidia fasciola, stage I (Packard, Proc. 

 Amer. Phil. Soc, xxxi, pi. ii, figs. 15-16) and in Apoda avellana (Chapman, Trans. 

 Ent. Soc. Lend. 1894, pi. vii, figs. 16-18.) Dr. Chapman remarks (k c, p. 345) 

 "When the larva has completed its development within the egg shell . . . it is 

 free from any spines or processes, but at the period of hatching, certain long spines 

 are rapidly developed." We cannot endorse Dr. Chapman's view that these spines 

 do not correspond to the tubercles. They seem to us to correspond to the warts of 

 subdorsal row, and their apparent alternation, in our species at least, is due to the 

 angle at which they arise from the body, rather than to a dislocation of their bases. 

 In Tortricidia pallida (which we hope to reach in due course) these spines of stage 

 I are in a still more interesting condition, being V-shaped, and thus intermediate be- 

 tween the single knobbed spine of Apoda and the three-pronged one of Adoneta. 

 (Packard, 1. c. p. ii, fig. 8.) It should be remembered that the spined Eucleids are 

 more generalized ihan the smooth ones, and we should not look for the most general- 

 ized condition of stage I in Apoda and allies, but in Adoneta and Sibine. In the latter 

 there are three setae from each wart, and no sign of alternation on successive seg- 

 ments, thus quite agreeing with our view, but not supporting Dr. Chapman's infer- 

 ence that the primitive arrangement corresponded to that of Eriocephala. (1. c, pp. 

 345-347- )
