LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 77 



6. EUDARCIA Clemens 



(Meessia Spuler) 



Face exceptionally rough; eyes extremely small, but prominent and visible from 

 above, behind the antennae, which are longer than fore wing. Fore wing (fig. 45) 

 with one medial lost; closing vein of accessory cell weak and arising before end of 

 discal cell, making R, and R 3 appear stalked together; hind wing two-thirds as 

 wide as fore wing, with broad fringe; one medial lost, cell open above Cu and 

 base of media preserved. 



The larva lives in a flat, ovoid, rough case, on lichens. E. simulatricella is 

 closely related to E. vinculella of Europe. 



1. E. simulatricella Clemens. Blackish; head ochreous. Fore wing with a fascia 

 a third way out, costal and dorsal spots opposite each other at middle, an apical 

 spot, not reaching either margin, and extreme tip of fringe white. 9 mm. (bipuiic- 

 tella Walsingham). 



Pennsylvania. 



2. E. caemitariella Chambers. Similar to E. simulatricella,, no white in fringe, 

 markings generally much narrower and more oblique. 9 mm. 



In the type specimen the fascia is broken; there are three median spots, the 

 middle one farther out and obscure, and two white spots beyond, on costa. 



This species has been confused with the similarly marked Ornix gutted,, but 

 the type is undoubtedly Adelid. I have seen no other specimens. 



Kentucky; Gulf States. 



7. ADELA Latreille 



Antennae (fig. 46) at least as long as fore wings, almost always several times 

 as long in male, but relatively short and roughly scaled toward base in most 

 females; with large basal joint. Eyes varying from very small to very large, 

 larger in male ; tongue strong, scaled at base ; maxillary palpi minute, porrect ; 

 labial palpi bristly; vertex with long, bristly hair, front variable. Hind tibire 

 in several species heavily bristled. Ovipositor of female strong, simpler than in 

 Tegeticula. Fore wings (fig. 43) with all ten veins arising from the cell, pre- 

 served, R 6 running to costa; all veins free, or R 3 and R^ shortly stalked; hind 

 wings with all veins free, or M, and M 2 connate or stalked; Sc much swollen at 

 base, R t not recognizable. 



The larvae (fig. 51), when young, live, as a rule, in flowers or seeds; when older, 

 they form a lenticular case of two, flat, oval pieces of leaf, in which they pupate. 

 Their prolegs are extremely primitive, each consisting of two areas of hooks, 

 grading off into the normal skin-granulations, and separated by a narrow fold 

 of membrane. The leg on the sixth segment of the abdomen is reduced, and there 

 is none on the anal segment. The pupa is normal.

No speculum. 



A white postmedian fascia 2. purpura. 



Immaculate blue 3. bella. 



1. A. ridingsella Clemens. Antennae relatively short (in male twice as long as 

 fore wing, and one and one -fourth times in female); face hairy, palpi moderate, 

 eyes small; fore wing with R-, and R, stalked, hind wing with M, and M, stalked. 

 Head dark, antennae annulated with white, fore wing yellow-brown, with a pale 

 grayish patch beyond middle, covered with rows of black dots; with a silvery
