Lepidoptera of New York and Neighboring States 547 



terminal space contrasting, white; lines fine, nearly black; orbicular and reniform 

 as before, heavy, and nearly filled with brown; antemedial line excurved from 

 orbicular to inner margin, an oblique basal line before it; postmedial line as in 

 B. ranalis, but heavier, the horizontal part slightly oblique above Cu, and touching 

 the lower side of the reniform; subterminal line nearly parallel to postmedial, 

 often touching the outer margin at Cu 2 , and the postmedial at its angle; twice as 

 far from postmedial below the horizontal part as above. A continuous brown 

 terminal line and a broken line in fringe ; a brown bar across the terminal space, 

 opposite the cell. Palpi less beaklike at the tip than in B. ranalis, the entire tip 

 brown; third segment short and blunt; maxillary palpi rather shorter. This 

 species and the next might go better in Lygropia. 15 mm. (magnalis auct. ) 



June. 



Central Illinois and southward. 



3. B. rivulalis Hampson. Fore wing with a fringe of rough hair on under side 

 of costa, fore coxa and femur with expansible tufts, head as in B. magualis. White; 

 more or less of base, costa, and whole outer margin pale yellow; markings brown- 

 black. Hind wing similar, base with four irregular and more or less interlocking 

 lines; the first and fourth typically complete and excurved, fifth line running to 

 orbicular; postmedial line much as in //. magualis, the offset running along Cu 2 

 and not touching the reniform, the space beyond it not white; subterminal line 

 well separated, except the horizontal portion, which is fused with the postmedial on 

 CUo. Reniform a double brown bar ; a brown bar beyond it in the postmedial space^ 

 below which there is an oval white patch above Cu 2 (this region is yellow in B. 

 magualis). Terminal line strong. 20 mm. 



Rare; in June and in late August. 



Quebec and Illinois, south to Pennsylvania and North Carolina. 



4. B. stenialis Guenee (figs. 322, 332). Light yellow, shaded heavily with brown; 

 the yellow ground most constant before the postmedial line, and the brown filling 

 the terminal area, except for a narrow line just beyond the postmedial line and 

 the costa toward the apex. Lines as in B. ranalis, thicker, but broken; orbicular 

 and reniform thick, obscured by the brown shading; basal line represented by a 

 brown shade. Hind wing similar. Palpi obliquely upturned with segments well 

 set off; the third segment a third as long as the second and broadly scaled; 

 maxillary palpi truncate, subtriangular, and as long as second segment of labials. 

 18 mm. 



Not rare; in swamps in June and July. Larva unknown, possibly aquatic. 

 Closely related to Geshna primordialis, and very near the point of separation of the 

 Nymphulinae and Pyraustinae. 



Generally distributed. New York: Gowanda (Wild), New Windsor. 



22. CONCHYLODES Guenee 

 (Spilomela Guenee) 



Labial palpi thick and smoothly upcurved; the first two joints rather marked, 

 not triangular, and third joint short and triangular. Maxillary palpi minute; 

 p.ntennae prismatic, front flat, oblique, prominent. Fore wing with R 5 slightly 

 approximate to R 3+4 ; hind wing with Mj shortly stalked, M 2 and M 3 approximate. 



The southern species C. diphteralis eats pecan. 



1. C. ovulalis Guenee. White, abdomen with fifth to seventh segments yellow, 

 second and fourth with black bands. Fore wing with straight basal and ante- 

 medial lines; postmedial line excurved from costa at four-fifths to inner margin at 

 four-fifths, fine except on costa; orbicular a black patch; reniform a heavy black 

 ellipse with a white line in the center; subterminal excurved, parallel to outer 

 margin, much heavier than postmedial line. Terminal line rather strong, black.
