indicated by a few brown scales. Apical spot_^is larger than hotrana, and there 

 are three|]smaller, rectangular, obhque spots on costa beyond the central fascia. 

 The inner spot, which in botrana is as distinctly defined as the other four, is'in 

 viteana not separable from central fascia. A few short streaks on costa before 

 the middle. A shade of pale yellowish-brown, involves the outer half of costa 

 between the central fascia and outer patch, giving the outer half of wing this 

 color. Hind wing: smoky-brown becoming paler at base. Expanse 10 to 11.5 

 mm. 



The many specimens bred by Professor Slingerland of the three broods on 

 cultivated grape, and one or more broods on wild grape are remarkably uniform 

 in coloration and maculation, and I have not observed a single specimen that 

 varies sufficiently to form a connecting hnk between any two of the five species 

 here treated. 



Larva: 9 to 10 mm. cylindrical, rather robust, tapering from 4 to head and from 

 8 to anal segment. Pale, oUvaceous green, with a reddish or purplish tinge 

 from food within. Head flattened, slightly bilobed, luteous green on upper 

 parts of lobes, discolored by brown in front. Mouth parts, and a horizontal dash 

 on each side of lobe below middle, black. Prothoracic shield large, but narrow, 

 luteous brown, bisected by pale green dorsal line. Thoracic feet black, green 

 between the joints. Tubercular plates moderate, a slight shade darker than 

 skin, shining. Anal plate not chitinous. 



Polychrosis liriodendrana Kearfott. — (Trans. Am. Ent. Soc, Dec, 1904). 

 Front wing : ground color, filaceous or leaden-blue, much as viteana, but extend- 

 ing farther outward and involving a greater area of wing; the bands and spots 

 in this species are nearly uniformly an ochreous olive-brown, a little paler around 

 the edges, but with hardly a trace of black which is so characteristic of viteana. 

 The outer patch is almost square, much smaUer than the two preceding species. 

 The outer spur of the central fascia is less produced than viteana, its upper limb 

 is broader, and it is considerably broader on and above dorsal margin. The 

 narrow fascia at inner third is more sharply angulated at middle than either 

 botrana or viteana, and Ln some specimens is almost obsolete. Four large, rect- 

 angular, costal spots, beyond middle, the outer one in the apex. A narrow, 

 oblique streak before the inner spot turns upward and merges into this spot. 

 The ochreous-ofive shade is most apparent on outer third of wing. Hind wing: 

 darker smoky-brown than viteana and less pale at base. Expanse 1 1 .5 to 12.5 mm. 



Larva: 10 to 11 mm. cylindrical, less robust than viteana, sUghtly tapering, 

 sordid green. Head yellowish-brown, oceUic field and lateral dash on lobes 

 black. Mouth parts only sfightly darker than head; prothoracic shield dark 

 brown; thoracic legs black. Tubercular plates, concolorous, sUghtly shining. 

 Anal shield not chitinous. 



The larva makes a narrow tent along one side of the midrib begirming near the 

 base on the imder side of the leaves of Liriodendron tulipifera, sometimes tun- 

 neUing the midrib for a length of 15 to 20 mm. As it increases in size, the tent 

 is widened, until at maturity a whole lobe of a leaf may be involved; rarely more 

 than one on a single leaf. Spring or first brood not observed. Second brood, 

 fuU-grown larvae July 2 to 9; moths issued July 10 to 21. Third brood of larvae 

 from Sept. 15 to Oct. 15; hibernates as pupae in the same form of cases as viteana. 



Polychrosis slingerlandana Kearfott.— (Trans. Am. Ent. Soc, Dec, 1904.) 

 Front wing: ground color, mottled shades of ochreous light-brown and dark- 

 brown, the leaden-lilaceous blue is nearly obsolete, occurring only as a cilate 

 band and a few scattered scales in basal third and streaks in outer third.
