398 BICHROMA; FIDONIA. By L. B. Peout. 



cretacea. I. cretacea Stgr. Unknown to me, perhaps not congeneric. Shape of carbonaria, pectinations much 



shorter. Forewing dirty chalk white with fine olive-grey dusting and 3 ill-developed dark bands, the two outer 

 approximated at hind-margin, diverging a little anteriorly, the distal running to the costa almost at apex; 

 distal margin with large black lunate spots; frmge with dark dividing line. Hindwing grey -white, towards the 

 distal margin somewhat darker. Transcaspia. 



limbaria. I, Hmbaria F. (= conspicuata Schiff., auroraria Hbn. part., circumdataria Vill., roraria Esp. nee F.) 



(23 d, e). Ground-colour above always bright yellow, lines entirely obsolete; very variable in the extent and 



arrangement of the dark dusting. Underside of forewmg without dark border, huadwing paler yellow, densely 



dusted so as to appear olivaceous or even fuscous, always with white of whitish streaks along the folds, or at 



least the radial one. The typical form has litl le dusting on the upperside of the forewing except along the costal 



quadripunc- margii:, but has a very conspicuous black distal border. — ab. quadripunctaria Fuchs has in addition distinct 



, /"'^"' black discal dots. — ab. fumata Matheiv has the yellow ground-colour more tmged with smoky and both wings 



delimbaria.densely dusted with blackish throughout. — delimbaria Stgr. is a small race with the black border narrowed, 



pedemonia- wanting on the hindwing, underside lighter. Digne. — pedemotitaria Stgr. is similar, but with the hindwing 



*"*?■ beneath almost unicolorous yellow. Piedmont and Alpes Maritimes. — anzascaria Star, is larger, paler at the 



margm, the wmgs ochraceous yellow, the black border either entirely wantmg on both wings or with \estiges 



rablensis. remaining on the forewing only. N. Piedmont: Val d'Anzasca.. — rablensis Z. has the ground-colour rather 



lighter than the type, more irrorated with black, the distal border in the $ dissolved into black irroration, 



styriaca. though still denser than on the rest of the wing. Carniola and Carintbia; also from Macugnaga. — styriaca 



Schwingenschus.s is somewhat smaller and narrower than rablensis, the (J more uniformly and densely irrorated 



and with less developed dark border, underside more whitish. Styria. — Larva green or brown, with light 



longitudinal lines and yellow lateral stripe. On broom. The pupa hibernates, the moth appearing in May, a 



second generation in July — August. Local in Central Europe. 



roraria. I. roraria F. {= adspersaria F., aiu-oraria Hbn. part., spartariaria Hbn., conspicuaria Esp., spartiaria 



Tr.) (23 e). Very similar to limbata rablensis but with the irroration more regularly distributed on the forewing 



above and especially on both wings beneath; forewmg aboA'C with broader distal border; hindwing beneath 



asqueatriga. without a trace of white streaks. — ab. aequestriga Hirschke lacks the dark border of the upperside. Silesia. 



— Larva very similar to that of limbaria, green with pale longitudinal luies. On Genista and Spartium. The 



pupa hibernates. Moth in June — July. Local in Central Europe, especially eastward, also recorded from 



Transcaucasia. 



;L46. Genus : ISichronia Gmpbg. 



•\ 



Related to Isturgia but with more protuberant face and especially distinguished by the foretibia, which 

 has a strong apical claw. Only one species. 



famula. B. famula Fsp. (= concordaria Hbn.) (23 e). A striking and very distinct species, perhaps least un- 



lUie some forms of atomaria ■^, but with stronger contrast between the colouring of the fore- and of the hind- 

 wing, larger cell-spot of the former, more slender lines of the latter, etc. Underside very prettily marked; fore- 

 wing orange to beyond the postmedian line, then with a row of large black spots, then concolorous with hind- 

 wing; hindwing white, latticed with brown. — Larva elongate, green with brownish head, dark dor.-al line and 

 broad whitish-yellow lateral stripe. On brooui. The pupa hibernates. Very local, Spain and Portugal to W. 

 ' Germany, Berlin, Central Italy, April— July, two generations m southern localities. 



147. Genus: Fidouia Tr. 



Also related to Isturgia but with the palpus longer, tongue wanting, antennal pectinations much longer. 

 Two species, inhabiting the Western Mediterranean countries. Probably Lbdekek was. justified in regarding 

 them as genera. . ■ . • 



A. li a i r }' c 1 o t h i n g ' n, o t more shag g y than i n Isturgia. Forewing with Idt — 2nd 



subcostal'short-stalk e'd (Athroolopha Led.). 



pennigera- F. pentligeraria Hbn. (23 c). , Recognizable at a glance by its large size and nearly uniform yellow 



'"'"' hindwing, only with quite narrow dark borders. The underside in a measure reverses the pattern, the forewing 



being yellow with dark costal (and at times distal) margin and dark apex, the hindwmg more mixed with 



fuscous, with a whitish postmedian band. Forewing above variable;, in the name-type the white bands are 



more dentate and inclined to break up into spots, the antemedian band is almost V-shaped. Distributed in 



chrysitaria. the Iberian Peninsula, S. W. France and N. .\frica. — chrysitaria Hb7i. (23 c) is on the whole' darker, the fore- 

 wing with distinct white stripes, tlie antemedian less acutely angulated in the cell and falling more perpendicularly 

 on the hindwing; hindwing with costal margin longer and free from fuscous shading. Underside of forewing 

 without dark discal mark, of hindwing vei-y variable, its pale band straighter. Probably a separate species
