and Texas. Larva somewhat flattened, grey or red with yellowish subdorsal lines and many yellow spots; on 
Nyssa sylvatica, the Tupelo-tree. 
8. Genus : .Ijeuconycta Hmps. 
Very similar to the preceding, distinguished by the frons lacking the horny plate, ciliated antennae, 
the thorax intermixed with hair and with loose tufts. 
L. diphteroides Gn. (5 f) is light green, strewn with white, with fine black transverse lines and maculae; diphteroi- 
conspicuous are a small black triangular spot near the base of the costal margin, and a large one from the 
costal margin entering into the maculae. Hindwing dusted with brownish with a central spot and traces of 
postmedian and subterminal lines. -—- In the form obliterata Grt. the black borderings of the posterior transverse obliterata. 
line and of the marginal lines are extinct. Canada, United States. —- Larva green with white dorsal and sub¬ 
dorsal lines and with a reddish stigmata! being below bordered with white, with single fine hairs on the partly 
white-dotted tubercles. 
L. vesta Schs. (5e) is silvery white, in some places dusted with red-brown, with very fine dark markings vesta. 
a black spot between the maculae and at the costal beginning of the postmedian line with a black triangular 
spot; fringes speckled white and brownish. Hindwing reddish-brown. From Mexico. 
9. Genus: Centrochlora Dyar. 
Distinguished from the preceding by its smooth frons, short, straight, porrect palpi, rough-haired and 
scaled thorax without tufts, from the following by short anterior tibiae with a spine on the inside. Only 
1 species: 
C. esmeralda Dyar (5 e) is a wonderful, dark green species marked white and black, also the hind- esmeralda. 
wings are intensely green. Mexico (City), taken in July. 
10. Genus: Agriopodes Hmps. 
Proboscis developed, palpi erect, extending to the centre of the frons, somewhat hairy. Antennae 
ciliated. Thorax covered with rough scales, without a tuft; abdomen at the base roughly haired, with a large 
dorsal tuft. Tibiae hairy. Several pretty greenish species. 
A. fallax H.-Schdff. (5 e) is emerald-green with a white costal margin and black, spotted markings, fallax. 
below which a triangular spot is particularly prominent analwards in the postmedian; subterminal line whitish, 
otherwise the marginal area is vacant, only the fringes are crossed by black. Canada to Texas. -— The velvety 
green larva with narrow white dorsal and subdorsal lines exhibits on the tubercles numerous, very fine, short 
hairs and lives on the snowball-tree. 
A. geminata Sm. (5 f) differs from fallax by the malachite-green wings being intermixed with white geminata. 
and black, with a much smaller subanal black triangular spot; the subterminal area shows black sagittae. 
From Canada. 
A. tybo Barnes (5 e) is light bluish-green, scantily strewn with black, with more coherent, finer tybo. 
black markings, transverse lines and maculae, the latter being large, finely surrounded with black; the subanal 
black triangular spot is entirely absent. Fringes speckled white and black. Hinclwing dusted with brownish- 
grey, with traces of a discal spot and postmedian line. Arizona. 
A. viridata Harv. (5 f) is very similar, smaller, separable by a very distinct, blackish discal shade and viridata. 
similar extensive dusting in the postmedian area. Hindwing lighter, almost white, with a black discal spot 
and 2 postmedian lines, and a black marginal lunular line. California. 
A. jucundella Dyar is a very small species; forewing light green with black triangular spots at the jucundella 
costal margin at the base, at the apex and anal angle; along the costal margin and at the distal margin in 
its centre there are besides small, black streaks; the other transverse markings are only represented by 
irregular, narrow, white, small strigae. Hindwing light grey, at the margin darker. Fringes whitish. Expanse 
of wings: 15 mm. Porto Rico, September. — The larva, according to G. N. Wolcott, lives on lichens and by 
the colouring being the same as the latter it offers an excellent example for protective colouring. 
A. lepidula Grt. (10 a) on its emerald-green ground is dusted with red-brown in the basal half of lepidula. 
the costal margin, in the discal area and in the centre of the postmedian area; transverse lines and maculae 
marked white, the former being double, finely bordered with black. Hindwing whitish, dusted with red-brown 
Canada to Colorado. — f. avirida Sm. (5 g) is not green, but greyish-white, strewn with dark brown; it occurs avirida, 
in the same range.
