LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 301f 



Cu, ? ) ; the remaining cubital widely separated from the other two, which are 

 connate. Hind wing with R 3 widely separated from stalk of R, to M^ RI from 

 beyond middle. Hind wing half as wide, with M 3 and CUj widely separated, M a 

 nearest M^ Mj connate with R. 



1. S. andropogonis Braun. Pale ochreous, dusted with dark brown. Head paler; 

 palpus with a brown spot on outer side of second segment, and annulus on middle 

 of third. Fore wing with the dusting denser at apex, gathering in longitudinal 

 streaks, and usually forming two oblique postmedial streaks on costa; costal fringe 

 ochreous, dorsal brownish, with brown terminal dots and a bar at apex. Hind 

 wing pale brown, fringes reddish ochreous. 9 mm. 



Larva in inflorescence of Andropogon scoparius, showing its presence by a yel- 

 lowish patch in the flower-spike. Moths in August, flying at dawn and evening, 

 and resting head down. 



Clermont County, Ohio. 



34. HELICE Chambers 

 (Theisoa Chambers; Cacelke Busck) 



Palpus with third segment very long, much longer than the second, which is 

 nearly smooth, curved, and fusiform. Fore wing lanceolate, with R 3 lost in the 

 male, usually stalked in the female, M 2 lost, M x long-stalked, and Tfj and Cu t 

 stalked, with more or less distinct gray scale-tufts. Hind wing half as wide or a 

 little more, lanceolate or notched below the apex, always very narrow. Sc two- 

 fifths length of wing, R often lost at base or entirely lost, and M a running to just 

 below the apex, (male) or with R and Mj represented by a single free vein running 

 just above the apex (female); Mo lost; M 3 and CUj stalked (male), or cell open 

 above M 3 ( female ) . 



The extraordinary sexual dimorphism in venation has had a curious effect on 

 the synonymy of this genus. It is the most reduced of the recognized Gelechiidae. 



I. Female with apex of hind wing produced, and outer margin concave below it 



(He lice). 



1. H. pallidochrella Chambers (fig. 173 5). Light gray, powdery, a small costal 

 dot near base, a large dark antemedial spot, crossing the cell but not crossing A, 

 a third way out; usually with a smaller costal spot at three-fifths way out, a 

 subtenninal shade on costa and a complex of dark streaks across apex of mem- 

 brane. 9 mm. (gleditschiceella Chambers; Cacelice permolestella Busck). 



Larva probably on Gleditschia. Moth in May and late summer. 

 Kentucky; Maryland; southern Ohio. 



II. Female with lanceolate icings as in male (Theisoa). 



2. H. constrictella Zeller (fig. 171 <$, 172 ?). Light wood-brown, shaft of 

 antenna lighter, annulate with dark brown. Fore wing darker at base, especially 

 before the antemedial line, which is excurved evenly, except for a sharp inward 

 turn in at costa, and followed by a paler shade. Sometimes with a black discal 

 dot; a blackish costal spot at two-thirds way to apex, followed by a pale one, the 

 boundary sharp and oblique, sometimes extending into a short fascia. Dorsal 

 fringe paler. 8 mm. (bifaciella Chambers). 



May to July. Larva on elm, forming a web on the under side of the leaf, con- 

 nected by a whitish tube of silk and frass to the base of the petiole; spinning a 

 thin, oval, silken cocoon. July and September. 



Massachusetts to southern Ohio and Texas.
