CELERIO GALLII. 173 



white stripe along each side, which is edged with black on the upper side, along the 

 thorax. The palpi are whitish beneath, and olive-brown above. The abdomen 

 is olive-brown, with a row of small white spots along the middle; the ist and 

 3rd segments are marked with black on the sides ; the 2nd, 4th and following 

 segments with white, some of them more or less suffused with pink. The underside 

 of. the thorax and the legs are of a dull yellowish-brown, and the abdomen is darker- 

 brown, with white lines along the edge of the segments. The forewings are olive- 

 brown, with a buff-coloured band extending from the hinder margin, near the base, 

 to the apex of the wing ; the lower edge of this band is slightly sinuous and the 

 upper is irregularly indented ; there is a black patch on the base of the wing and 

 another at the end of the cell, and the terminal space and fringes are olive-grey. 

 The hindwings are black, with a rose-red central band, which ends in a white spot 

 on the hinder margin ; the outer margin is narrowly edged with dull brown, which 

 is sometimes stained with reddish ; fringes white. Larva : The mature larva is 

 from 2§ins. to 3ms. long; the head is dull red, with a black stripe across the face; 

 the upper side of the body is deep olive-green and polished, with a pale yellowish 

 line along the middle of the back, terminating at the base of the caudal horn, and 

 there is a row of pale yellow spots on each side from the 3rd to the 12th segments 

 inclusive ; these spots are placed on a wide blackish band, which crosses the forward 

 part of each segment, and the sides of the body, below the spots, are thickly 

 sprinkled with minute yellowish dots ; the caudal horn is long, curved backwards, 

 red, tipped with black, and with the surface rough ; the spiracles are oval, yellow, 

 and margined with black. The underside is pale pinkish -green, the true legs" black, 

 while the prolegs are pink, with a black spot on the outside of each. Transforma- 

 tions subterranean. Foodplants : This larva feeds on the leaves of grape, 

 CEnothera biennis, Epilobium angustifolium, E. coloratum. Habits : Flies 

 about flowers in the twilight in June and July (Fernald), at wild plum bloom (Can. 

 Ent., xxxiii., p. 99). Distribution : Canada, Manitoba, Labrador, United States- 

 New England, &c. (Fernald). 



We have preferred to give Fernald's description of this insect, 

 and Kirby's original description merely as a footnote, as this author 

 states that his description was made from an old and faded example. 



Egglaying. — In confinement, the moth lays its eggs singly, 

 whilst hovering over bedstraw, willowherb, or fuchsia, holding, how- 

 ever, the plant with its legs during the process, but with its wings 

 vibrating all the time ; a few seconds suffices for laying an egg, 

 when it is immediately off to another sprig of its foodplant. The 

 egglaying period for a single moth often extends to three or four 

 weeks, the 2 appearing to develop eggs all the time, a total of 

 300 to 400 being reached for a single ? , if properly ted, but 

 if the weather be hot, and the feeding not up to their requirements, 

 they will not lay more than 40 or 50 eggs, and will die within 

 a week. The eggs are laid from early June until about the middle 

 of July, and hatch, under satisfactory conditions, in about a week. 

 The early-laid eggs often result in larvae and pupae that develop 

 autumnal imagines (Head, in litt.). Paget obtained eggs at Great 

 Yarmouth, in August, 1834, from which larvae hatched in due 

 course (Ent. Mag., ii., p. 435). May notes eggs laid in 1870 

 as hatching on August 16th (Ent., v., p. 201). Jenner had 

 eggs laid on August 24th, 1870, at Lewes (E.M.M., vii., p. 213). 

 Williams records that a worn ? laid about a dozen eggs at St. 

 Margaret's Bay, July, 1888, and that seven hatched before August 

 8th (Ent., xxi., p. 230), whilst Austen notes that three eggs laid by 

 a ? on July 29th, 1888, hatched August 8th, at Folkestone (I. c, 

 p. 231). 



Ovum. — Length almost rimm., width just under imm. A 

 flattened disc, inclining to circular in outline, exceedingly small for the 

 size of the moth ; a deep irregular depression on the upper surface ;
