color of costal margin between fascia and apex, whitish blue, four brown costal 

 spots in this space, the inner a mere outwardly oblique line curving into outer 

 lower end of second spot, latter and fourth are triangular-oblique, third spot 

 rectangular. Below these spots and above the white patch are scattered a few 

 brown scales. Cilia bluish grey, darker at apex and light fuscous at anal angle 

 Underside dark fuscous, whitisli below fold, three geminated whitish spots on 

 costa before apex, and a number of others on extreme edge of costa only, between 

 these and base, cilia darker with narrow light subciliate line. 



Abdomen smoky black, with metallic reflection, anal tuft silvery-white above, 

 yellowish beneath, tipped with dark fuscous; underside abdomen whitish; legs 

 same inwardly and between joints, outwardly smoky-black. 



Hind wing: — Smoky fuscous, lighter towards base, darkest at apex, cilia paler; 

 underside fuscous. 



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

 8 to anal segment. Pale olivaceous-green, with a reddish or purplish tinge from 

 food. Head flattened, slightly bilobed, luteous green on upper parts of lobes, 

 discolored by brown in front; mouth parts and a horizontal dash on side of each 

 lobe below middle black. Pro-thoracic shield large but narrow, luteous brown, 

 bisected by pale green dorsal line. Thoracic feet black, green between joints. 

 Tubercles plates moderate, a slight shade darker than skin, shining. Anal plate 

 not chitinous. 



First brood complete, from hibernating pupse of the complete third 

 and partial second broods; issues in May and deposits eggs in the 

 flowers of the grape, larvse feed on recently got berries. Second 

 brood not complete, part issuing middle of July and depositing eggs 

 on half grown grapes, but some of the pupse of this brood hibernate 

 and do not issue until the following spring; this habit has been 

 ob.served on both the cultivated and wild grape specimens. Third 

 brood complete, issuing latter part of August and ovipositing on 

 yearly full size grapes, larvae completing growth and in pup?e by the 

 latter part of September. Pup?e of all broods formed in a neat little 

 flap or envelope cut out of edge or internal part of a leaf. 



The ground color of viteana and the inner half specially well de- 

 fined, is a leaden blue or lilaceous-blue, crossed by a narrow choco- 

 late brown line at first quarter. The central fascia is more slender 

 than botrana, its outer spur is sharply produced and in some speci- 

 mens turning upwards towards costa and almost joining submargi- 

 nal patch. Apical spot is larger and the costal spots before it are 

 smaller than in botrana. Hindwings dark brown. 



Polychrosis liriodendrana sp. nov. 



Head, palpi and thorax light brown, or fawn color, tips of palpi and outer ends
