68 SCOTOGRAMMA. By W. Warren. 



4. Genus: Scotogi'amma Smith. 



Differs from the two preceding genera in the frontal projection not being truncate, but simply 

 strongly protuberant. 



Type S. submurina Grate, from N. America. 



trifolii. S. trifolii Itott. (= chenopodii ScMff., verna Esp., treitschkei libit.) (15 g). Forewing grey, dark- 



speckled: costa black-spotted: claviform stigma small: orbicular round, pale, sometimes whitish: reniform 

 large, the lower lobe dark grey, all three finely black-edged; veins towards termen finely black; hindwing 

 dull whitish, with abroad border and the veins fuscous. — Common throughout Europe; in Algeria, Syria, 

 saucia. Siberia, Turkestan, Tibet, and Kashmir. — saucia Esp. (15 g) is the form showing a tendency to an 

 farkasii. ochreous tint; -- in ab. farkasii Tr. (15 h) the forewing is more variegated, light and dark, the larger pale 

 indistincta. orbicular stigma and a pale patch obliquely below it forming a prominent streak; — indistincta Tittt (15 g) 

 albifusa. has a uniform dull appearance, without speckling; — albifusa Walk:, described originally from a N.American 

 specimen, but probably a rare general aberration, has occurred at Portland, on the chalky South coast of 

 England: it is grey with a yellowish gloss, with a pale band as in farkasii, joined by a second pale oblique 

 band from apex. -- Larva varying from green to brown, thickly dark-dotted; dorsal line fine, pale, sub- 

 dorsal lines broader, all black-edged; spiracular stripe broad, yellow varied with reddish. On Atriplex and 

 Chenopodium. 



marmorosa. S. marmorosa Bkli. (— odontites Bad.) (15 h). Forewing dark brown; the orbicular stigma conspi- 



cuously pale, with a bifid pale patch obliquely below it; claviform stigma broad, rounded at end ; sub- 

 marginal line dentate, pale; veins 3. 4 and 7 broadly lined with pale to termen; hindwing dark brownish 

 fuscous, the fringe pale. — Occurs throughout S. Europe, in Spain, France, Switzerland, Germany, Austria, 

 microdot!. Hungary, and Russia: also in Turkestan, Mongolia, and Tibet in Central Asia; — microdon Guen. is a 

 much darker mountain form from the Alps and Pyrenees. — Larva violet-grey; dorsal line dark; subdorsal 

 and lateral lines yellow, edged with dark dots; on various plants, feeding up in early summer. 



implexa. S. implexa Him. (~ fallovi Oberth.) (15 k). Forewing ferruginous brown, dusted with whitish scales, 



especially along veins and costal area; the lines marked with white; two upper stigmata brown edged with 

 white; claviform absent; hindwing brown, paler towards base. — Found in Hungary and S. Russia in 

 Europe: in Syria, Armenia, and Transcaucasia in W. Asia; Oberthuk's fallovi was described from Algeria. 



dianthi. S. dianthi Tuusflt. (= dentigera F.r., actinobola Er.) (15 h). Forewing brownish-ochreous ; lines 



black strongly edged with pale; claviform brown, with linear pale centre; a broad pale streak above it 

 and shorter one beyond it; cell brown; the upper stigmata ochreous with paler edges, conversely oblique; 

 teeth of submarginal line produced to termen along veins 3, 4 and 7; hindwing dirty whitish, terminal half 

 blackish, with pale fringe. Hungarv and S. Russia in Europe; Asia Minor, Armenia and Turkestan in 

 W. Asia. 



treitsdtkci. S. treitschkei Bad. (= pugnax Hbn.) (18 a). Resembles S. trifolii, but the colouring and markings 



more conspicuous; claviform filled in with dark; the wedgeshaped black marks before the submarginal line 

 stronger. Found only in S. France. — Larva velvety black with four yellow lines; spiracles white; head 

 and forelegs black; venter and hindlegs reddish grey. On Hippocrepis and other low plants. 



sodne. S. sodae Rami. (15 h). Forewing dull drab; the small claviform and large reniform stigma consjDi- 



cuously dark with partial black edging; orbicular annular; irregular dark shading on each side of sub- 

 marginal line; all the lines indistinct; hindwing dingy pale grey becoming smoky fuscous towards termen; 

 the fringe pale. A mediterranean species occurring in autumn on the coasts of Greece, Italy, S. France, 

 Spain , and Algeria. - Larva green , with dark dorsal vessel ; each segment with a subdorsal dark streak 

 underlined with white; spiracles white, on dark triangles, above a 3 r ellow lateral line; feeding in May and 

 June on Salsola, Chenopodium maritimum and other coast plants. 



stigmosa. S. stigmosa Chr. (15b). Like sodae but the ground colour white, the lines and markings clearer; 



orbicular stigma more irregular; hindwing white, with the dark border subterminal, preceded by traces of 



grisescens. a postmedian line; --a smaller darker form, ab. grisescens ab. nov. has the ground colour of forewing grey, 



and the border of hindwing marginal, broad and well defined. — Sarepta in S. Russia, W. and E. Turkestan, 



Transcaspia, and Afghanistan. 



armata. S. armata Sigr. (18a). Forewing brownish-grey, with median area darker; veins white-lined; a 



dentate mark at base of vein 2; claviform stigma long, blackish, with pale linear centre; upper stigmala

 preceded by dentate black marks; hindwing fuscous with paler base. Occurs only in W. and
