100 BEITISH BUTTEKFLIES. 



10. — With, the forewings above of a pale and golden brownish-yellow (which 

 might be designated cinnamon-brown, pale-chamois or buff, slightly iridescent) at 

 the base, in the cell, and along the inner margin. This colour insensibly shades off 

 into the normal tint as it approaches the apex and outer margin. Blachier Coll. 

 (Blachier, in lift.). 



11. — ? , with the right forewing pallid (ochreous), except at apex. Algeciras, 

 March 27th, 1901 (Yerbury) (Brit. Mus. Coll.). 



12. — With a pale patch on the outer margin of the right forewing. Taken at 

 Cuxton, May 6th, 1893 (Tutt coll.). 



13. — With a plate patch at the anal angle of the left forewing. Taken at 

 Cuxton, May 6th, 1893 (Tutt coll.). 



14-15. — Two specimens from St. Leonard's Forest, having a pale spot in each 

 forewing (Boyd, Proe. Ent. Soc. Lond., 1871, p. xix). [Possibly these refer simply 

 to examples with pale androconial patches, and are not pathological examples 

 at all.] 



Egglaying. — In 1896, Le Grice discovered the 2 s of C. rubi 

 ovipositing on Helianthemum vulgare in Folkestone Warren. He 

 observed that the imagines flying over brambles, elder, guelder-rose, 

 etc., were all $ s, and, following up a 2 flying low down and evidently 

 on egglaying intent, noticed that she selected the Helianthemum, laying 

 the green eggs, usually singly, on the upperside of a leaf, but some- 

 times on the stalk or flower-bud ; this plant seemed, at the time, to be 

 the only one selected. Prideaux later observed the 2 s laying on twigs 

 of Rhamnus catharticus, usually, although not invariably, at the base 

 of the calyx. He also notes eggs being laid freely, in confinement, on 

 shoots of gorse, the 2 s being confined with these in a glass jar placed 

 in the sun ; eggs laid June 10th, produced larvae on June 18th. In 

 1898, Filer also observed eggs being laid on the leaves of Helian- 

 themum vulgare, and later on the petals of TJlex europaeus. On April 

 10th, 1906, Chapman imprisoned a number of 2 s on Calycotome in a 

 sleeve, but failed a week after to find an egg; he continued, however, with 

 further insects and fresh plants, until, on the morning of April 17th, 

 he obtained some ten or twelve eggs. The butterfly, he says, is very 

 loth to lay, and would not oblige on heath or cistus, which had been 

 placed with the Calycotome. Their unwillingness may be due to the 

 unsuitable character of the plants given, owing to the peculiar habit 

 of the 2 in laying her eggs between two surfaces, for which purpose 

 the 2 ovipositor, chitinous, wedgeshaped, protrusible for a length of 

 lmm., free from scales, and with a slight fringe of terminal hairs, is 

 peculiarly adapted. All the eggs were found on a surface, with some 

 object close above it, which always touched and adhered to the upper 

 surface of the egg, though usually only to a small part of it. A 

 favourite place was between two or more flowerheads, but, in several 

 instances, the egg was on a leaf, but with another bit of leaf or some- 

 thing touching it, in one case on the new stem, beneath a bit of dead 

 leaf that adhered to it. In several cases, the egg was so buried as to 

 be nearly invisible, and could not be exposed without separating the 

 portion adhering to its upper surface. Buried like that of Cupido 

 minima, which, however, is easily seen by separating flowers, never 

 adhering but by its base, the egg was in no degree deformed by the 

 attachment, as those of many Noctuids are, except as regards the 

 surface sculpture. The egg itself is green, rather flat, the top plate 

 and the sculpture triangular, six ribs radiating from a raised point, 

 but not always going to another point. On April 25th, 1906, Chapman 

 found an eggshell on a twig of Calycotome : it was close (2-5mm.) to 

 the thorny point of the twig, and surrounded by three buds, now a
