AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



205 



The genus and its type species were described from 

 a single female. The male is unknown, so the above 

 diagnosis is incomplete. The habitus of neaeriatella is 

 that of a pale ignidorsella so the placement of Wunderia 

 near Eurythmidia seems safe enough. 



The genus is readily identified by the open cell of hind 

 wing, the otherwise Eurythmidia venation, and the 

 absence of a signum. Grossbeck's description is faulty 

 in one respect. The front is not "projected forward in 

 the form of a cone." The scaling projects Ln a conical 

 tuft, but the front itself is evenly roimded. 



408. Wunderia neaeriatella Grossbeck 



Figures 90, 948, 949 



Wunderia neaeriatella Grossbeck, Bull. Amer. Mus. Nat. Hist., 

 vol. 37, art. 1, p. 133, 1917.— McDunnough, Check list, 

 No. 6361-1, 1939. 



Markings and color of forewing similar to those of 

 Eurythmidia ignidorsella e.xcept slightly paler. The 

 female type is somewhat rubbed, which accounts for 

 the traces of a dark transverse antemedial line and the 

 dark discal markings mentioned by Grossbeck. Before 

 me are three females from the Cornell Collection, col- 

 lected at San Germdn, Puerto Eico, Apr. 16 and 17, 

 1930. In these the entire area below the whitish costal 

 stripe is pale grayish fuscous without transverse lines 

 or appreciable discal spots, and there is a very faint 

 orange blotch on middle of dorsal margin (as in igni- 

 dorsella) distinguishable on one of the specimens. The 

 whitish costal stripe is sparsely dusted with reddish 

 scales and there is a scattering of similar scales on the 

 dark area. The Puerto Kican examples are certainly 

 congeneric and I believe conspeciiic with the Florida 

 type. 



There are some differences in the female genitalia 

 (shown in figs. 948, 949); but these are merely in the 

 size and shape of the bursa, differences which are prob- 

 ably of no more than individual significance. The 

 Puerto Rican specimens are rather small (12-12.5 mm.) 

 compared with the type (14.5 mm.). 



Type locality: Everglades, Fla. (Apr., type in 

 AMNH). 



Food plant: Unknown. 



The male is unknown. 



Genera 110-114: Oedothmia to Cacozophera 



[Venational division D. Forewing with 10 veins; 9 present; 4 

 absent; vein 2 from before but near lower outer angle of cell. 

 Hind wing with discocellular vein curved. Labial palpi up- 

 turned or oblique. Transtilla incomplete or altogether absent.] 



110. Genus Oedothmia Hampson 



Oedothmia Hampson, Ann. Mag. Nat. Hist., ser. 10, vol. 5, p. 60, 

 1930. (Type of genus: Oedothmia endopyrella Hampson.) 



Synothmia Hampson, Ann. Mag. Nat. Hist., ser. 10, vol. 5, p. 61, 

 IPSO. (Type of genus: Synothmia bahamasella Hampson. 

 New synonymy.) 



Clarke and Tams have compared the types of Hamp- 

 son's two supposed genera and inform me that they 



appear to be no more than sexes of one species. Hamp- 

 son's chief character for separating Oedothmia and 

 Synothmia was the shape of the frons, conical on 

 Oedothmia and roimd on Synothmia; but Clarke states 

 that his description of the former is at variance with 

 the type in several details — the male antenna is simple, 

 the shaft not excised at base, and the frons isroimd.not 

 pointed. The venation of the types of the two genera 

 is similar. 



Tongue well developed. Antenna pubescent; shaft 

 simple. Labial palpus upturned; the second segment 

 reaching above vertex; third segment "thickly scaled." 

 Maxillary palpus filiform. Forewing smooth; 10 veins; 

 vein 2 from very near to lower outer angle of cell; 3 

 from the angle, approximate to 2 for some distance from 

 cell; 4 and 5 united, shortly separated from 3 at base; 

 6 from below upper angle of cell, straight; 8 and 9 

 stalked for about haK their lengths; 10 from the cell, 

 separated from 8-9 at base; male without costal fold. 

 Hind wing with vein 2 from lower outer angle of cell; 

 3 from the angle, contiguous (but not fused) to 5 for 

 half their lengths; 7 and 8 contiguous beyond cell for 

 some distance, but not anastomosed; cell short, less 

 than one-third the length of wing; discocellular vein 

 curved. 



Male genitalia unknown; the type of 0. endopyrella, 

 and only known male, is without abdomen. 



Female genitalia resembling those of Eurythmidia 

 and Oncolabis; with the signa strongly developed, the 

 large spined plate situated in bursa like that of Oncolabis 

 but the collar of strong spines at junction of bursa and 

 ductus is lacking; genital opening simple; ductus semi- 

 nalis from bursa near its junction with ductus bursae. 



The genus is easily distinguishable from its nearest 

 relatives in venational division D (except Stylobasis) by 

 the approximate condition of veins 2 and 3 of forewing. 

 From Stylobasis it is distinguished by the contiguous 

 rather than anastomosed condition of veins 7 and 8 of 

 hind wing, its upturned labial palpi and simple male 

 antennae.

Markings and color similar to those of Oncolabis 

 anticella ZeUer, from which it can be distinguished most 

 readily by its venation. Alar expanse, 16-18 mm. 



Type localities: Vera Cruz, Mexico {endopyrella, 

 in BM); Nassau, Bahamas (bahamasella, in BM). 



Known only from the two types.

 segment enlarged; on male shaft with a hook from its 

 basal segment and deeply curved for several segments
