396 SONGARICA; PYGMAENA; ITHYSIA; ATOMORPHA. By L. B. Prout. 



140. Genus : l^oug^arica Gmpbg. 



Structural characters unknown, as Gtjmppenbebg merely founds his genera on the M'ing-shape and 

 I am not acquamted with the species. „Costal margin arched, distal margin flexuous, all the angles distinct." 

 Antenna filiform, but the sex of the example is not indicated. 



inollioularia. S. mollicularia Ev. About the size of Cosymbia punctarin. Uniform, soft greyish fawn-colour, without 



dark shadings, only a rather broad median area (rather more than one-third the wing-length) slightly darker, 

 bounded by /ine whitish, very finely crenulate lines, which run parallel with the distal margin except near the 

 costa, where they are curved proximally; a fme whitish subbasal line also present. Hindwing with the post- 

 median line continued, curved parallel to the distal margm. Underside without markings, ground-colour nearly 

 as above. Noor-Zaisan. 



141. Genus : Pygniaeiia Bsd. 



Differs from Psodos in the more slender, narrower wings, those of the 9 extremely narrow (unfitted 

 for flight), (J antenna with short pectinations, forewing m the (J with a fovea. Only one species. 



fusca. P. fusca Thnbg. (= venetaria Hb7i., canitiaria Frr.) (:?3 d). (J dirty brown-grey to black-grey, $ rather 



lighter, both wings with black discal dot, forewing also with 2 Imes which vary much hi distinctness. ■ — ab. 



"TeMrla'aia unistrigata Strand lacks the antemedian line. — In ab. destrigata Strand both luies are wanting. — Larva short, 



thick, with transverse skin-folds; dark reddish brown, with black, yellow-edged dorsal stripe and yellow lateral 



stripe. On low plants, hibernating. Scandinavia, Finland and the highest Alps. 



142. Genus : Ithysia Hbn. 



Face with rough projectuig bans. Palpus rather short, rough-scaled. Tongue short. Antenna in ^ 

 bipectmate to apex, with short branches. Pectus hairy. Legs slightly (the ^ femora more stronglj') hairy. 

 Wings of (J long and narrow, forewing pointed, 1st subcostal anastomosing or connected with costal, 2nd 

 free. Only one species, no doubt related to the Nyssia group. 



pravaia. \. pravata Hbn. (23 d). ^ quite unmistakable on account of the curved white band of the forewmg 



from the base to near the apex and the white veins. $ light grey to yellowish, more yellow at the segment- 

 incisions, the thorax dorsally brown. — Larva smooth, nearly cylindrical, pale yellowish much dotted with red- 

 brown, dorsal line fine, double, extremely ill-defined, subdorsal and lateral lines and an mtermediate one pale, 

 continuous, fmely edged with red-brown, dorsal area somewhat darker, traversed by sunilar fme lines (from a 

 preserved larva in the British Museum). Sarepta, common in May. 



homochro- Liodes homochromata Mab. (25 h) as homogrammata), placed by Staudingbr between Ithysia and 



mata. jsiarraga, is probably not determinable untO the structure can b," exammed, although Mabille gives a good 

 figure. Small, wings not very broad, rather recalling a narrow-winged Dichronwdes, an appreciable bend at 

 the extremity of the 3rd radial of the hindwing. Antenna bipectinate. Forewing uniform shining blackish 

 grey with some iridescent yellowish scales. Fringe and hindwing paler. Underside similar, costa of forewmg 

 suffused with fulvous. Corsica: Bastia, t. smgle ^J believed to have been bred from Genista Corsica. 



143. Genus: Atoiuorpha Stgr. 



Face rounded. Palpus short. Antenna in ^ ciliated. Body relatively robust. Foretibia extremely 

 short, furnished with one or two terminal claws. Wings somewhat broader than m Narraga, distal margins 

 smooth. Forewing with cell rather long, 1st — 2nd subcostal coincident, connected by a bar with 3rcl — 4th. 

 Hindwmg with costal closely approximated to cell for some distance, sometimes anastomosing, 2nd subcostal 

 sometimes shortly stalked with 1st radial, 2nd radial wanting. 



An interestuig little genus, recalling Lithostege except m the neuration, but connected with the following 

 through the American Fernaldella, which has the foretibial cla-w- but is otherwise almost a Narraga. All the 

 species are Palearctic. I have seen very little material and do not know the type species falsaria. The genus 

 was described by Alpheeaky under the preoccupied name of Atomophora which Staudingek (probably by 

 oversight) changed to Atomorpha; the change was accepted by Alpheraky and is here m.aintained. 



falsaria. A. falsatia Alph. Rather longei-whiged (more Narmga-lHie) than the following, greyish white, coarsely 



dusted with brown, the large cell-spot and 2 Imes formed by agglomerations of the brown scales; antemedian 

 line broad, straight, vertical, postmedian still broader, forming a smuous band from costa about 2 mm. before 

 the a.pex to hitidmargin adjoming the anal angle. Hindwing regularly but in general rather less densely irro-
