the second costal streak is replaced by a faint, curved, dark line, 

 emitted from a small bluish brown costal spot. The transverse 

 striation caused by the rows of slightly raised scales is apparent. 

 The antennae are pectinated. 



While the two males from Hawaii before me do not exhibit much 

 variation, a similar range of variation as is found in the females may 

 be expected in the males. 



Alar expanse, 20-23 mm. 



Habitat Tantalus and Makiki, Oahu, Hawiian Islands, 

 Otto H. Swezey, collector. 



Type No. '12777, U. S. National Museum. 



The types of this very distinct species were bred by Mr. 

 Otto H. Swezey, assistant entomologist of the Hawaiian Sugar 

 Planters' Association, who writes as follows, under date of 

 October 26, 1909 : 



This tortricid is quite a pest in the Hawaiian Islands. The larva? 

 are leaf-rollers on many kinds of plants, shrubs, and fruit-trees, often 

 so numerous as to defoliate the trees and sometimes attacking the 

 fruit as well. It is an introduced species here which has been present 

 for several years. No one here knows where it came from, nor has 

 anyone learned its identity. 



The species has long been known to the writer from Mexico 

 and has undoubtedly been introduced from that country to 

 Hawaii within comparatively recent years. In the National 

 Museum are specimens from Jalapa, Santa Rosa, Orizaba, 

 Vera Cruz (Wm. Schaus coll.), and Mexico City (R. Miiller 

 coll.), Mexico, and from Costa Rica (Wm. Schaus). The 

 species comes nearest the darker and larger North American 

 species, A. cuneana Walsingham. 



The genus, which is characteristic of America, has veins 

 7 and 8 in the forewings stalked in the female, coincident in 

 the male, but is, aside from this secondary sexual character, 

 amply defined by characters common in both sexes, the ven- 

 ation and form of the hindwings, and the raised scales of the 

 forewings.
