Show 324 ON NORTH-AMERICAN TINEID.E. [Feb. Ii examples to examine the neuration, I can find no difference in structure beyond the very slight modification above referred to. A careful comparison of the descriptions of ^Etole and Heliodines shows them to be at least very closely allied, if not identical; and as Mr. Chambers's figure of the neuration of his Mtole Bella (Journ. Can. Soc. Nat. Hist. Jan. 1880, p. 26, fig. 54) does not seem to agree precisely with his previous description of the number and position of its veins, there may, perhaps, be some doubt as to the sufficiency of the evidence on which he separates them. iETOLE, Chambers (Can. Ent. vii. p. 73). " Scales of the head appressed; forehead wide, obtuse. " Antenna? simple, rather thick, about as long as the body; basal joint short." Tongue long and naked. No maxiliary palpi. " Labial palpi very short, drooping, the third joint pointed. " The discal gives off two branches, the superior being furcate before the apex, with one of the branches to each margin" (figured simple, not furcate). Fig. 1. Mtole bella. HELIODINES, Stainton (Ins. Brit., Lep. Tin. p. 243). " Head smooth; forehead obtuse. " Antenna? setaceous, almost as long as the body; basal joint short, cla-vate. " Tongue of moderate length." (No maxillary palpi mentioned, none existing.) " Labial palpi small, rather thick, acuminate. " The furcate apical vein terminates in the apex and in the hinder margin." Heliodines rcesella. Neuration of wings. If the upper fork of the apical vein (apparently described, but omitted in the figure, by Mr. Chambers) be inserted, the neuration of the two genera will be found to correspond very closely, with the exception of the absence of a short vein in AUtole which in Heliodines runs from the lower edge of the cell to the dorsal margin, which may possibly have been overlooked. Mr. Chambers places his genus among the Elachistidae, and states that it "resembles closely the European Chrysoclista linneella," which is the British genus placed nearest to Heliodines by Mr. Stainton, although not so placed in Wocke's Catalogue. |
