Lepidoptera of New York and Neighboring States 359 



4. IDIOGLOSSA Walsingham 



(Metamorpha Frey and Boll, not Hlibner, Walker, or Stainton; 

 Idiostoma Walsingham) 



Vertex and front smooth scaled; the front strongly narrowed below, as in 

 Coleophora. No ocelli; scape of antennae very long; pecten apparently absent; 

 a notch in base of shaft. Palpi widely divergent, second segment slightly thick- 

 ened, third as long as second. Maxillary palpi drooping, clothed with a con- 

 spicuous tuft of hair-scales; tongue scaled; hind tibia? with two or three regular 

 series of bristles. Mid-tibiae smooth. Wings linear; R 5 running to costa; cell low 

 in wing, oblique, like Coleophora; one dorsal vein lost. Hind wing linear. 



This is a very striking genus, distinguishable from all our other narrow-winged 

 Tineina by the metallic bands on the linear hind wings. The relationship is 

 entirely uncertain. The genus shows resemblances to Coleophora, Cosmopteryx, 

 Batrachedra, and the Gracilariidse. There is another species in South Africa, and 

 two more in India. 



1. I. miraculosa Frey and Boll. Straw yellow. Palpi and maxillary tuft nearly 

 white. Fore wing with an oblique brownish fascia a third way out, nearer the 

 base on dorsal margin, sending a point outward along the middle of the cell, and 

 edged with violet-silver. Another fascia running obliquely outward from the 

 beginning of the costal fringe, edged within with silver; and brownish fuscous 

 streaks in the fringe below. Extreme apex silvery. Hind wings nearly con- 

 colorous, with three silvery fascia?, somewhat edged with brownish, the outer one 

 followed by a stronger brown shade which extends into the fringe. Two brown 

 scale-tufts in dorsal fringe of fore wing and one on hind wing. 10 mm. 



Caterpillar on Panicum clandestinum, in a translucent white silken tube on the 

 under side of the blade, attacbed through a hole to the upper side of the leaf, 

 which the larva skeletonizes. Pupation in the tube, which is trussed up and 

 enclosed in loose silk. 



Southern States, north to southern Ohio. 



5. CYCLOPLASIS Clemens 



Antenna? very short, hardly more than half as long as body; palpi short, diver- 

 gent, oblique in life, slightly curved, with terminal bristles; with flat scale-masses 

 beside the tongue, possibly representing the maxillary palpi; Tongue somewhat 

 longer than face. Fore wing linear-lanceolate (fig. 221) ; R near costa, simple, 

 fading out at base; a vein through middle of wing, furcate over apex (represent- 

 ing R s and M) ; Cu very short and simple. Hind wing- linear, abruptly broadened 

 at base, with a simple vein running to apex, and a fragment of Ctl in the basal 

 lobe. Middle and hind tibia? and tarsi heavily spined; hind legs elevated in the 

 resting position. 



The larva lives in a long linear mine, which is later enlarged into a blotch. 

 When mature, it cuts out an oval piece of the mine, and folds it lengthwise to 

 form a cocoon, in which it drops to the ground and anchors itself. A mass of 

 white froth is ejected from the end of the cocoon. I suspect the pupa is obtect. 



This isolated genus is placed here by Meyrick; the peculiar cocoon would sug- 

 gest rather the Heliozelida?, but the food and maxillary palpi may indicate more 

 direct kinship with Idioglossa. 



1. C. panicifoliella Clemens. Head and thorax lead-color; antenna? brown, with 

 silver toward base ; fore wing umber brown, more or less violet, with a broad 

 straight bright silvery fascia a third way out, and suffused with silver in apical 

 half, especially toward costa: fringe and hind wing violet brown; fringe of hind 

 wing fuscous.
