spiracles, straight, defined above and below. Subventral area reddish ; 

 feet pale ; spiracles black ringed ; tubercles and setae minute. On joint 

 12 the oblique shades join a medio-dorsal shade, forming a trifid mark 

 that is rounded behind. 



Food plant not stated. Alameda Co., Cal. A. Koebele, No. 583. Be 

 fore the last stage the larva is green and differs considerably in appearance. 



30. Orthosia bicolorago Guene"e. 



Head 2 mm., shining brown, vertical band and reticulations darker 

 brown, distinct throughout. Body greenish, heavily mottled with red- 

 brown ; cervical shield brown, mottled, faintly divided by dorsal and dis 

 tinctly by subdorsal lines. Dorsal line pale, narrow, pulverulent; oblique 

 shades brown, each filled in before to the dorsal line, producing a series 

 of dark segmentary triangles, the base in front and a little produced along 

 the dorsal line. Subdorsal line pale, narrow, pulverulent, throwing off 

 faint branches that partly border the oblique shades behind. Substigmatal 

 line indicated by pale mottlings, obsolete. Spiracles black, in dark areas ; 

 feet pale, leg plates dusky; tubercles and setae minute, in pale areas. 



Food plant, maple. Dept. Agriculture, No. 3369. 



31. Glaea olivata Harvey. 



Head 3.6 mm., pale brown, the vertical band and reticulations distinct, 

 but not very dark; reticulations fine. Body olivaceous, mottled with 

 brown, and dotted with pale; shield more uniformly brown, cut by the 

 lines. Dorsal line narrow, pale, straight; subdorsal pale, but nearly lost 

 in the dots and mottlings. Substigmatal band broad, sharp edged, just 

 touching the spiracles, but well below those on joints 2 and 12, yellowish, 

 broadly centered with red-brown mottlings, edged above by a narrow dark 

 brown line that partly encloses the spiracles. Feet pale ; spiracles black 

 ringed ; tubercles and setae minute. 



Food plants oak and wild cherry. Dept. Agriculture, No. 3357. 



32. Glaea inulta Grote. 



Head 3.8 mm., pale brown, the usual markings nearly obsolete, but the 

 tubercles, mouth, and sutures of clypeus dark brown, these sutures trisect 

 ing a faint orange-yellow band that extends across between setae viii of the 

 two lobes. (Seta viii is just above ix, both being above the base of an 

 tenna.) Body translucent, sordid whitish, immaculate, the tubercles, 

 shield, and anal plate cornified, brownish. Spiracles black; legs with 

 dark claspers ; tubercles and setae small. 



Food plant Viburnum nudum. Dept. Agriculture, No. 3368. The head 

 of this larva is marked curiously like that of Charadra deridens. Judg 

 ing from this unusual marking and the thin skin, one would say that this 

 was a concealed feeder, living in a spun-up leaf. 



33. Jodia rufago Hiibner. 



Head 3 mm., light brown, the vertical band and reticulations darker 

 brown, distinct ; clypeus pale. Body light brown, finely mottled on a pale
