Eyes large, somewhat prominent and widely separated beneath. 

 Antennae slender, scarcely exceeding one half the wing length ; 

 basal joint with pecten. Forewings elongate, pointed, without scale 

 tufts; all veins present and free, 10 arises near end of cell; no 

 accessory cell; l 6 furcate. Hindwings as wide as the forewings, 

 ovate, costa retuse beyond middle; all veins present, 5 and 6 stem- 

 med. Hind tibia roughened, with long, coarse hair. Ovipositor of 

 female exserted. 



The type of the genus resembles a Tinea of the croceoverticella 

 group. The absence of plicate maxillary palpi, the peculiar forma- 

 tion of the labial palpi, which have the appearance of a branch of 

 pitch pine, removes this genus from the neighborhood of Tinea. 



A. carbonella n. sp. — PI. V, fig. 1. — Entire insect, with exception of hind- 

 wings, dark fuscous brown ; bristly hairs of labial palpi like those of the head, 

 tipped with white. Forewings elongate, obtusely pointed ; the general fuscous 

 color is interspersed with scattered dark brown and also paler scales, the former 

 aggregated into a spot at end of cell and also generally more dominant in apical 

 part of wing where they are somewhat arranged into ill-defined lines. Hind- 

 wings pale fuscous, with brassy lustre, cilia concolorous, with paler basal line. 

 Abdomen and underside of body ochreous fuscous. Tarsal joints paler at apex. 



Expanse 14.0-19.0 mm. ; 0.56 0.76 inch. 



Hab. — Pennsylvania (Hazleton). 



Seven specimens in my collection, all taken at electric light, in as 

 many seasons. It has not occurred since 1900. A specimen sent 

 to Lord Walsingham was returned under the MS. name Tinea car- 

 bonella, the specific name of which I have retained. The white 

 tipped, rough hairs of head and palpi give them a peculiar, hoary 

 appearance.

 Dyar's List, p. 570. 



Head rough, tongue present; an ten use about three fourths the 

 length of the forewings. Labial palpi porrect or somewhat droop- 

 ing, second joint with apical bristles, third joint pointed. Maxillary 

 palpi well developed, plicate. Posterior tibiae rough haired. Fore- 

 wings with a vitreous spot in the disk, corresponding to end of cell ; 

 all veins present, veins 3 and 4 stalked, vein 2 sometimes out of stem 

 of 3 and 4 ; \ b furcate at base. Hindwings 1, cilia generally under 

 1 ; all veins present, free, or rarely 5 and 6 stemmed. 



According to variation in venation the species occurring in our 

 fauna may be arranged in three groups as follows :
