HYLOPHILINA. By W. Warren. 297 



crests: head rough haired: forewing with costa straight, apex prominent, termen obliquely curved, even; veins 

 8. 9. 10 stalked: hindwing with 3, 4 stalked; the retinaculum bar-shaped from subcostal nervure; forewing 

 green with oblique pale streaks; hindwing without markings. Larva smooth, broad in front, attenuated behind; 

 feeding exposed on trees; pupation in a silken boatshaped cocoon. The imago emerges in early summer, the 

 larva is fullfed in autumn. Type H. prasinana L. 



H.prasinanaL. ( = faganai^.,viridisdmeata,Rete,sylvanal'\, milliereiCap»-.)(53k). Forewing yellow green; prasinana, 

 costal edge pink, diffused towards apex; inner marginal area pink-suffused, except towards base; inner and 

 outer lines oblique, darker green, conversely edged with white, the outer sometimes pink; subterminal line white, 

 curved into apex: fringe pink with a white line at base; hindwing yellow; fringe pale pink, white at tips from 

 apex to vein 2: abdomen white, dorsally suffused with yellow; in the $ the abdomen is white, tinged with brown 

 at base: forewing with costal edge white, and inner margin yellow; hindwing white. In the British form subsp. 

 britannica subsp. nor. (53 k), all the 3 lines are silvery white; the costal and inner margins in the <$ reddish only britannica. 

 at apex and tornus respectively; in the ab. rtifilinea ab. nov. ( = ab. 2 Hmps.) (53 k) the outer line is marked rufilinea. 

 with red. Larva apple green coarsely shagreened with yellow; the subdorsal line yellow; segment 2 red-rimmed 

 in front : on various trees. A common European insect, occurring also in West and East Siberia and Japan. 

 The imago stridulates on the whig. 



H. kraeffti Graes. (= magnifica Leech) (531). $. Forewing olive green, terminally paler; costal and hraeffti. 

 inner marginal areas broadly pink, except at base and towards termen; a broad oblique outer band pink, followed 

 by deep olive green; subterminal line white, running into apex; termen and fringe pink; hindwing pink, with 

 pale interspaces ; f ringe white at tips ; the dorsum pink ; $ yellow green ; the costa white faintly tinged with 

 pink: hindwing white; the veins and inner margin ochreous; dorsum ochreous. Recorded from E. Siberia and 

 W. China. 



H. sylpha Btlr. (53 1). Forewing pale green varied with white; costal and inner margins ochreous tinged sylpha. 

 with {link; inner and outer lines white, oblique, converging towards costa, the median area darker green along 

 them; termen and fringe white, pink-tinged; hindwing pure white. Japan. 



H. hongarica spec. nov. (53 k). Forewing pale, somewhat bluish, green in $, yellowish green in <$; inner hongarica, 

 margin reddish in q to base, slightly in $ in outer half; fringe red in^, paler in $, often olive green; an 

 outer white line parallel to termen, not emphasised by darker green ; inner line very faint, often obsolete ; when 

 visible whitish, parallel, or nearly so, to outer line and not reaching costa; hindwing white in $, yellowish green 

 in o ; underside whitish green in $, yellow green in <J; head and thorax green; abdomen in $ greenish white, 

 in (J yellowish, with fulvous yellow hairs at base; palpi, legs, and antennae red. Herculesbad. Hungary. Out of 

 more than 3 dozen $$ and over a dozen <$<$ not one shows any variation towards prasinana. 



H. japonica spec. nov. (53 1). Resembles hongarica, but the inner line is plain, and both are rather japonica. 

 more oblique; distinguished from sylpha by its shorter and broader wings. A pair from Yokohama and a^ from 

 Asamayama in the Tring Museum. 



H. buddhae Alph. Forewing delicate pale green, with a single oblique white line from middle of inner buddhae. 

 margin parallel to termen; fringe traversed by a red line; hindwing pure white. Described from a single $ from 

 the province of Sze-chuen, W. China. Although I have described the two preceding species, from Hungary and 

 Japan respectively, as distinct, it is not impossible that both are forms of buddhae; the unique type of this 

 insect may be an example with the outer line more central than usual, while the partial or entire absence 

 of the inner line is not uncommon in the $$ of hongarica. 



8. Genus: Hylophiliiia gen. nov. 



Differs from Hylophila hi the retinaculum of <J being a tuft of hair from below median nervure, and 

 hi the head being smooth. The larva feeds up in spring, emerging as imago in the summer. Type H. bico- 

 lorana Fuessl. 



H. bicolorana Fuessl. (= prasina Poda nee prasinana L., prasinana F ., nee L., quercana Schiff.) (53 m). bicolorana. 

 Forewing bright apple green; the costal edge yellowish white; inner margin narrowly white; inner and outer 

 lines finely yellowish white, oblique, the outer from costa before apex; hindwing white; fringe white in both 

 wings; in subsp. conspersa subsp. nov. (53 m), from Amasia, the ground colour is blue green, densely covered eonspersa. 

 with pale scales; the costal edge and lines white. Larva green, smooth; the 3rd segment with a yellow tipped 

 dorsal hump; subdorsal and spiracular lines yellow; some pale yellow lateral stripes; feeding on oak. Occurs 

 throughout Europe and in Western Asia: Armenia, Asia Minor, Syria.
