318 SYNEGIA. By L. B. Peoxtt. 



pusaria. C. pusaria L. (15 g, as pusata). White with slight grey dusting and fine grey lines, on forewing 3 



■ ablataria. (the first curved), on hindwing 2. — ab. ablataria Fuchs (= monotonica Strand, striaria Hbn. praeocc.) has the 



heveraria. lines almost or entirely obsolete. — ab. heveraria H.-Schdff. (= melania Oh.) is a rare form in which the 



rotundaria. grey dusting densely covers almost the entire wmgs. England, Germany and Austria. — ab. rotundaria Hmv. 



(= confinaria Frr.) is a rounder-winged form with the first lines strongly approximated. Said to be the 



product of under-feedmg the larvae. — Larva elongate, with rather flattened head; green with purplish brown 



or blackish dorsal spots, or grey mixed with reddish, or sometimes yellowish; verj' variable. On birch and 



alder. Pupa compact, brown, the wings olive-green; hibernating. On the wing through a great part of 



the summer, irregularly double-brooded. Europe, generally abundant, Transcaucasia, N. Persia and E. Si- 



~ fleicheri. beria. — hybr. fletcheri Tutt (pusaria ^J x exanthemata $) is just intermediate between the parent forms, 



rather pure white, the lines tinged with ochreous. 



exanthema- Q. exanthemata Sco'p. (= striaria Hbn.) (15 g) is sUghtly shorter-wmged, more tinged with ochreous, 



the irroration (which is generally stronger) and the lines being ochreous grey; lines rather more denticulate. 



arenosaria. — ab. arenosaria Haiv. (= nogentina Th.-Mieg) is darker, more strongly dusted, the lines sometinres scarcely 



approxi- _ or not at all differentiated. — • ab. approximaria Haw. has the first2 hnes closely approxunated, almost coales- 

 nelleararia ^^^^- — ^- pcllagraria Guen. is said to be larger, apex of forewing more produced, colour whiter, less irrorated, 



unicoloraia. lines perhaps less waved, both wings with a black discal dot. Lyons. — ab.' unicolorata Teich, almost unico- 

 lorous whits, is said to be a prevalent form in Livonia. — Egg oval, green, with fine reticulation. Larva 

 very variable, green or brown, usually with dark dorsal markings and sometimes with white dots. Perhaps 

 rather thicker than pusaria larva. On sallow, etc. Pupa similar to that of pusaria. Range nearly the same, 

 but apparently more distributed in Central Asia. 



schacjjeri. C. schaefferi Brem. (15 g) is, as Leech says, a separate species, characterized by the distinct yelloM' 



bands, which are not denticulate, ground-colour cleaner white; all the Imes of the forewing are curved 



sinicarki. basewards anteriorly. S. E. Siberia, Korea and Japan. — sinicaria Leech has the ground-colour more yellowish 

 white, thus at first sight more like exanthemata, but ^^■ith the lines as in schaefferi. "\V. China: Ta-chien-lu. 



purKs. C. purus Btlr. (15 g) is also very similar to exanthemata, the ground-colour cleaner white, the lines rather 



more markedly dentate, curving nearly as in schaefferi, from which it differs, apart from the dentate lines, 

 m having a fine grey irroration and on both wings a black discal dot. Japan and Korea. 



punckda. C. punctata Warr. (= candidaria Leech) (15 g). Structurally distinct in having the 1st subcostal vein 



stalked with the others, superficially in its macular bands, which are somewhat variable in distinctness. Ground- 

 colour chalky white. Japan: Oiwake. 



rjriseolim- C. griseolimbata Ob. (= straminea Btlr., ustulataiia Chr.) (15 g). Apparently not clearly related to 



«• ii^Q other species, but agreeing in structure. Superficiallj' more hke a Lomographa, very distinct in the reticu- 

 lated appearance, due to the dark veins, and in the broad dark border of the hindwing and of the posterior part 

 of the forewing. Ussuri district and Japan. 



rufojascla- C, ( ?) rufo?asciaria Leech. Also very distinct. Pale ochreous broAvnish with black discal dots, the forc- 



rla. \yiQg ^vith broad diffuse rufous outer band. Chang Yang, Central China, only the type larown, a $, aberrant 

 in its pectinate antenna and rather longer palpus. Perhaps a separate genus. 



24. Genus : ^iynegia G 



Men. 



Related to the precedmg group but differing in the longer palpus and altogether more slender build, 

 the cj abdomen bemg long and thm, anteima long, legs long and slender. (J antenna generally pectinated, 

 but variable. ^ retinaculum often modified either into a dense hairtuft or into a spatulate plate. 



lmdrxsn:i, S. hadassa Btlr. (15 g). ^ antenna with moderate, slender pectinations; retinaculum normal. Bright 



ochreous, irrorated with fuscous; both wings with black discal dot. Very variable. La the name-type the fus- 

 cous irroration is massed so as to form cloudy bands bordering the median area (the postmedian dentate) 

 and forming a dark proximal (and sometimes distal) shading to a dentate subterminal line of the ground- 

 inconspi- colour. — ab. inconspicua jB<?r. has the irroration more reddish, giving to the entire wmgs a brighter ochreous 

 . '''^"'- tone, the cloudy bands more or less weak. — ab. unicolor Wileman has the irroration coloured as in the 

 suffusa' type, but entirely lacks the bands. — suffusa fo)7n. nov. has the hindwing and a great part of the forewing 

 dark-suffused, leaving free the basal area, the cell and a narrowing streak from this to the apex, crossed 

 by the postmedian and subterminal dark bands, a still darker dentate postmedian line usually distinct. All 

 specimens from Kiushiu are of this form or transitions. — hadassa is distributed in Japan; also known 

 from Chang Yang, Chow-pin-sa and Mou-pin.
