7360 Insects. 



Leath. Egc/. — The female never flies until after copulation or depositing; lier eggs, 

 which she jiays around the stems of the food-plant, in May and June. The larvas 

 emerge in from fourteen to twenty-one days, feed during the summer and autumn, 

 undergo three clianges, aud then descend to the roots of heath, where they s])in 

 a slight weh, and so continue during the winter months. In the following spring 

 they again come forth, and feed during the summer, undergoing three or four further 

 changes of skin, and make up into pupae during August and September. Imago. — In 

 May and June of the subsequent year the perfect insect comes forth. Tlie females of 

 B. Callunae possess the peculiar power of attracting the male, which is a characteristic 

 of this family ; by this means numbers of males are captured. — W. Shipston (in 

 the ' Intelligencer^) ; 3, Lower Brunswick Street, Halifax, November 14, 1860. 



Description of ike Larva of Epione advenaria. — Eggs laid June 23. Oval ; yellow, 

 changing to red and then smoky. Hatched July 10: tried the larvae with several 

 plants; at last they began to feed on rose: afterwards procured bilberry for them, 

 which they refused. The bilberry does not grow in the wood where the perfect insects 

 are taken, but the comraou white burnet-rose abounds. At first dark brown, nearly 

 black, with four white bands, having a granulated appearance ; head black and white. 

 After first moult dull purplish brown, with yellowish white spots (two near dorsal line 

 the longest and most conspicuous), nearly forming a band on front of 6th segment; 

 two similarly coloured spots on 12ih segment, aud an undulated lateral line of same 

 colour, broadest behind, where it is mixed with the ground-colour, as that also is 

 freckled with yellowish ; head dull black, with two yellowish streaks. Full fed 

 darker, especially towards the head, marbled with gray ; whitish marks as before, but 

 less conspicuous. Went into pupa among moss drawn together by a few threads, 

 October 30. I always fed it with a smooth-leafed rose growing in the garden, as 

 nearly like the wood-rose as I could find, and it always ate freely. It will be seen by 

 comparing the dates that it was a long time in the larva state. I have tried the wood 

 where the perfect insect is taken for the larva, but in vain. — E. Horlon (in the ' Intel- 

 ligencer ') ; Wick, Worcester. 



Description of tke Larva of Odontopera bidentala. — A true Geometer, but having 

 eight claspers, the usual pairs on the 10th and 13th segments, and a pair each on the 

 8lh aud 9th segments; these last are perfectly formed in every respect, but are 

 extremely small, and totally useless in walking : the 12th segment is slightly humped, 

 the swollen portion crowned with two small warts, and there is a narrow oblique vel- 

 vety ridge, on each side of llie l'2lh segment, leading towards these warts : the head is 

 decidedly but not deeply notched on the crown : the body is a good deal wrinkled 

 transversely, and is of a dull brown colour inclining to purple, with scarcely ,auy 

 shading or variety of colour. I beat a considerable number of these larvae from 

 birch at the end of September, and on the 2nd of October they ceased eating, and, 

 hiding themselves in moss, changed to pup£e with scarcely any cocoon. — E. Newman. 



Description of tke Larva of lodis lactearia. — Body extremely long aud slender : 

 posture when at rest straight or curved, not uniformly the same. Head prone, with 

 the mouth bent under, the crown deeply divided, terminating in two sharp lobes ; pale 

 brown: 2ud segment bearing two sharp-pointed approximate humps on the back ; 

 none of the other segments bear either warts or humps : body pale delicate green, 

 with a dull red median spot, laterally bordered with yellow, on the interstices between 

 the segments following the '3xd. Feeds on oak: full fed September 16th to October 

 12th. Spins a lew threads across the leaves of its rood-])lant, and turns into a pupa 

 in the home thus formed : it remains in the pupa state all the winter. — Id.
