106 THE ENTOMOLOGIST. 



Leiopiilus, Wallgn. 

 Tephradactylus, Huh. 

 (Plate II., Fig. 4.) 



Imago. — Expanse, 8-9 lines. Ground colour of fore wing whitish 

 brown, thickly sprinkled with dark grey scales, giving an ashy appear- 

 ance to the whole wing. Before the digital juncture are two small blackish 

 dots, that nearest the costa being slightly the largest. On the outer digit, 

 near the tip, are three small blackish dots arranged in a triangle. There 

 are also three blackish dots on the hind margin of inner digit. Fringes 

 grey. Tip of outei- digit subacute. Hind wing grey-brown ; fringes slightly 

 paler. Head and thorax whitish grey. Body pale yellowish grey, with 

 darker dorsal markings. June and July. 



Larva. — Length, 5 lines, attenuated at both ends. Head shining pale 

 yellowish brown ; mandibles reddish brown ; spot on each cheek black. 

 Ground colour green, with more or less of a yellowish tinge. Dorsal stripe 

 whitish, with a median area darker than ground colour. Subdorsal line 

 wavy interrupted yellowish. Tubercles, dorsal, two rows (four on each seg- 

 ment), whitish, with tufts of whitish hairs ; one hair from each of the 

 posterior warts longer than the rest, and the tip slightly reflexed. Sub- 

 dorsal, a row of small warts each with a single whitish hair. Spiracle 

 region, on the middle of each segment is a semitransparent wart, with a 

 tuft of moderately long whitish hairs ; and just above, on the posterior edge 

 of segment, is a smaller one, with short whitish hairs. Legs yellowish 

 green. Food, golden rod [SoUdago virgaurea), when young, boring into the 

 shoots; afterwards eats holes in the expanded leaves. May and June. 



Pupa. — Greenish, with warts and hairs as in larval stage ; an olive- 

 green stripe immediately under the dorsal row of tubercles, and under this 

 again is a pinkish shade. ^Ving-cases pale green, with a lateral fringe of 

 white hairs. Attached by the anal segment, head downwards, to the stems 

 of food-plant or sides of cage in confinement. June and July. 



Fig. 4, golden rod [SoUdago virgaurea) ; 4 a, larva ; 4fc, pupa ; 4 c, imago 

 of L. tephradactylus. 



The imago of Leioptilus tephradactylus runs very close to that 

 of L. Lienigianus in structure and coloration ; but the absence of 

 the costal spots at once separates it from the latter sjpecies. 



Young hybernatecl larvae may be found as soon as the food- 

 plant is above ground, eating the tender shoots, often three or 

 four larvae on one shoot. They are then about the size of a larva 

 of Arctia mendica just emerged from the egg, and in colour 

 whitish, with long grey hairs. 



On sunny days the larva rests on the lower part of stem or 

 under a leaf, but on dull days seems to feed at intervals all day.
