 NOTES ON SOME TORTRICID GENERA WITH DE-V^ ^ 



SCRIPTIONS OF NEW AMERICAN SPECIES. ^"^ , ^ 

 BY AUGUST BUSCK. 



The Tortricid moths, placed in European and American cata- 

 logues under the generic names Heraimeiie Hiil>ner, (Dichro- 

 ntmpha Guenee), and Lipoptycha Lederer, form a natural, easily 

 distinguished group, which is at once separated from all other 

 Tortricids (of p]urope and America at least) by having veins 6 

 and 7 in the hind wings remote at base and nearly parallel ; in 

 all the other genera, l)ut two,* these two veins are either ap- 

 proximate, connate or stalked. 



The group is an immediate offshoot from the more generalized 

 genus, Laspei/resia Hiibner (Meyrick & Walsingham) f and the 

 species can from their general habitus alone be confounded with 

 no other genus l)ut that and Pammene Hiibner, another paral- 

 lel offshoot from Laspei/rcsia ; some of the species of these latter 

 genera are in general appearance very similar to the group under 

 consideration, and others also approach it in having veins 6 and 

 7 in the hind wings rather distant instead of closely approxi- 

 mate as is normal ; but by consideration of the pterogostic 

 and oral characters combined, there is no difficulty in placing 

 any of the species in its proper group.! 



The two genera Hemimene and Lipoptycha are by European 

 authors at present separated on Lederer 's original character, 



* Isotrins Meyrick, which belongs to another subfamily and can not be confounded 

 with the present group, and the West Indian and South American genus Balbis Walsing- 

 ham ; I am not acquainted with the type of this genus, Carpocapsa assumptana Walker, 

 except through a carefully colored figure of Walker's type specimen, but it appears to be 

 very close to Hemimene and must be separated from it by the palpi, which are like those 

 of Laspeyresia.

X Thus macukma Fernald, described as a Lipoptycha, clearly belongs to Laspeyresia, 

 neur interstinctana Clemens; Professor Fernald was presumably misled by the certainly 

 nearly parallel (still distinctly approximate) veins 6 and 7, but the curved ascending 

 labial palpi with the short brush and short apical joint indicate its proper genus. This 

 genus, placed under the name Enarmonia, Hubner, by Professor Fernald (in Dyar's List 

 N. Am. Lep. p. 469, 190;?) is nut, as given in the synonomy, equal Enarmonia Meyrick, 

 which is the genus called Epinotia by Professor Fernald (SteganojitychaStephens, Rebel).
