POLYHYMNO SEXSTRIGELLA Chambers. 



Polyhymnn sexdrujeMd Chambers, Dyar, Cat. N. Am. Lep., No. 5649. 



Six specimens. Tlie.se are the first specimens of this elegant species, 

 which have come to the National Museum collection since the unique 

 .specimen there, named by Lord Walsingham. 



UNTOMIA, new genus. 



Labial palpi long, recurved; second joint somewhat thickened with 

 smoothly appressed scales cut off sharply at the end of the joint; ter- 

 minal joint smooth, pointed, longer than second joint. AntenniM sim- 

 ple, rather thick; forewings elongate ovate, obtusely pointed, with 11 

 veins, vein 8 lacking; 7 to costa 6 separate, veins 3 and -1 stalked, 1^ 

 furcate at base. Hindwings as wide as forewing, broadest at tornus, 

 apex produced, pointed; termen sharply emarginated below apex; 8 

 veins, 3 and 4 connate from corner of cell, 5 curved upward from the 

 same point, 6 and 7 connate, 7 to apex, 2 distant from 3 and -1 and the 

 transverse vein between 5 and 7 obsolete. 



The genus is a development from Gelechia on the lines of Aproaerema, 

 from which it differs mainly in the more specialized venation, the 

 absence of vein 8 and the stalking of veins 3 and -1 in the forewing and 

 the open cell in the hindwing. 



Type of genus. — Untomia untomiella. 



UNTOMIA UNTOMIELLA, new species. 



Labial palpi on the exterior side blackish brown, second joint with 

 apex white, inner side light fuscous. Antenna? dark fuscous. Face 

 whitish, head and thorax pur- 

 plish fuscous. Forewings 

 dark fuscous, irregularly and 

 sparsely sprinkled with ochre- 

 ous and blackish scales; on the 

 middle of the cell is a longitu- 

 dinal black dot, at the end of 

 the cell is another more promi- 

 nent black dot. At the begin- 

 ning of the dorsal cilia is an 

 outwardly directed oblique narrow white streak, nearly parallel with 

 the edge of the wing and reaching nearly to apex where it is met by a 

 similar costal white streak; both of these are often more or less incom- 

 plete and faint and the small size of the insect makes the ornamentation 

 obscure. The insect looks like a diminutive A2)roaerema eoncinnusella 

 Chambers. 



Alar expanse. — 8-9 mm.
