124 IVELA; CARAGOLA; PANTANA. By Dr. E. Strand. 



In July. Larva black with a row of light dorsal spot and yellow lateral line. Segments 4 and 5 each with 

 a pair of united fleshy pointed tubercles. It lives on species of willow and poplar, hibernates, is often 

 noxious and pupates in a loose cocoon between leaves, the pupa being glossy black with white spots and 

 yellow tufts or hair. The moth appears in July and August. The (^(^ already begin to fly before dusk 

 in the evening and often swarm like snow-flakes round the poplars and willows at country-roads. 



flcvo- S. flavosulphurea Ersch. Closely allied to salicis, but forewing and thorax sulphur-yellow, the hind- 



sulphurea. ^^^^^^ .^j^^j abdomen lighter. Pectinations of antennae light. ^ 35 mm. Ferghana, Sarafshan district, and 

 cre/cM^a.perhaps near Ajigora. — The ^ of cretacea 67(//-. (22 d) is chalky white or greyish white, $ whitish. From 

 Issyk-kul. 



ochropoda. S. ochropoda Eversm. (22 d). White, with the forelegs, tarsi of hindlegs and palpi ochreous, the 



pectinations of the antennae being black. Forewing of $ with very slight sulphur-yellow suffusion. From 

 South-Estcrn Siberia and the Ussuri district. 



sarius. S. sartus Ersch. (21 d). Wings uniformly greyisli brown, body above slightly ligher. Antennae 



gi-eyish yellow. ^ 33, ? 35 mm. Sarafshan district, Ferghana, Issyk-kul, Tian-shan. 



c!i<ina. S. cygna Moore (= cymbicornis 5m//.) (20 b). ^ pure white, wings in life with a liright light 



green sheen and semitransparent, veins yellowish. Antenna boat-shaped, very long and with light brown- 

 ish yellow pectinations. Tips of palpi yellowish. Tibiae and tarsi of the fore and middle legs with black 

 spots on the outerside. 48 mm. East Asia. 



moorei. S. nioorei Leech, from C'hina, is almost like cygna, but the wings are shorter and the nuirgin is 



more rounded; the shaft of the antenna black with the exception of the base. $ pure white, wings with 

 glossy silvery white scales, which form numerous slightly raised transverse bands; forewing with small 

 black discocellular spot. Wings broader than in Arctornis alba Brem. 28 to 29 mm. 



12. Genus: Ivela Sirinh. 



So closely allied to Stilpnotia that the only species would perhaps be better placed in that genus. 

 The palpi are shorter than in t;V|3ical Slilpnotia as conceived by Hampson, but scarcely shorter than in 

 S. salicifi, i)orrect. In facies less robust, abdomen cylindrical and not extending beyond the anal angle, 

 costal margin of forewing convex, and the apex of the forewing more rounded than for instance in S. 

 salicis, margin convex, almost not oblic{ue and in this very distinctly differing from salicis, hindmargin 

 also romided. I do not find any other noticeable difference in the venation except that in the forewing 

 the stalk of veins 7 and 8 is considerably longer and also that of 8 and 9, vein 9 being therefore very 

 short (about as in S. comma Hutt., cf. Hampson, Fauna of Brit. India, I p. 487). It is not correct 

 that vein 10 originates at one-third before the end of the cell, as Svvinhoe states; its position is as. 

 in salicis. Areole absent. Hindwing broader and more obtusely rounded than in salicis. 



auripes. I. auripes Bull. (20 b). (J greyish white, forewing with silvery scales, especially on the veins, dust- 



ed with greyish brown and very slightly suffused with dark grey along the costal margin (most distinctly 

 below), and also along the veins; antennae longer than in Arctornis l-nigrum, with a black spot near the 

 base, and with black pectinations. Fringes almost imperceptibly darker than the wings and glossy. 

 Discocellular .spot absent. Forelegs golden-yellow, the others with yellowish tarsi. 50 to 63 mm. $ larger, 

 costal margin, veins and fringes scarcely darker, femora white below. Expanse 55 to 70 mm. Japan. I have 

 only compared specimens from Corea; they correspond to the smaller dimensions given. 



13. Genus: Caragola Moore. 



A genus consisting of few, mostly Indo-Malayan, medium-sized, white naoths with small porrect 

 palpi; hindtibia with only one pair of spurs, and antennae bipectinate. In the forewing vein 3 originates 

 rather far before the apex of the cell, and 5 from the apex, 6 from the anterior angle, 7, 8 and 9 stalked, 

 10 from the anterior margin of the cell without forming an areole (always ?). 



sericea. C. sericea Moore. $ pure silvery white. Palpi and inner side of forelegs black. Forewing without 



bands of raised scales. 38 mm. Kashmir, Sikkim, Masuri, Tibet. 



14. Genus: Paiitaiia Walk. 



This genus consists of a few exclusively South and East Asiatic moths of medium size, M'hich 

 are usually uniformly coloured and marked, of comparatively slender build, with large wings, the hind-
