270 THE entomologist's record. 



6, Court Road, West Norwood. Auf/iist 4:th, 1904. [The peculiarity 

 pointed out by Mr. Palmer has already been noted by Mr. Burrows 

 (Xatural Histori/ of the British Lepidoptcra, vol. iii., p. 208). It is 

 remarkable, as we have noted {op. cit., p. 207), that the primary green 

 tint of the egg is on maturity confined to an area beneath the surface, 

 the egg being somewhat opalescent, the green markings then ap- 

 pearing directly beneath the surface reticulation. — Ed.] 



Ovum of Pamphila sylvanus, Esp. — At midday, July 24th, 1904, 

 I saw a $ of this species deposit an egg on the underside of a blade of 

 Brachypodiuvi sylvaticimi. The egg was upright, would have been 

 spherical, but was much flattened at the base, vertical axis to hori- 

 zontal axis as 0-75 to 1. Under a lens the micropyle appeared as a 

 slight depression on the summit of the egg, with a minute raised point 

 in the centre. The general surface appeared smooth, but there were lines 

 running irregularly in all directions over it like veins in marble. When 

 first laid the colour of the ovum was grey, but in some lights it looked 

 green from the reflection of the leaf. It did not alter in colour. On 

 the sixth day a black spot appeared in the centre, and two days later 

 it hatched, the larva only being eight days in the egg. The weather 

 was very hot during the period. The larva was white, with large 

 black head and a narrow black thoracic plate. — Alfred Sigh, F.E.S., 

 Lausanne. Sci>U'mher lith, 1904. 



Egg of Phryxus livornica. — [Description made from an empty 

 egg-shell received from Mr. E. E. Bankes] . No doubt the egg when 

 laid is green, but of what tint and what further colourings it assumes 

 up to the time of hatching, the shell, of course, affords no information. 

 The shell is very perfect, there is a comparatively very small hole by 

 which the larva escaped, unfortunately, apparently involving the 

 micropyle, and there is, on one side, a shallow dent, which may be the 

 result -of an accident, but is more probably the sHght collapse that 

 affects so many eggs during the period of maturation, representing the 

 loss of fluid by evaporation, and corresponding in its nature to the air 

 at the end of a hen's egg. The following description is made from 

 the egg in this state. [Unluckily, when I had done with it and pro- 

 posed to lay it aside, I thought I might attempt to smooth out the 

 depression above noted, but the only result was to add others, so that 

 the specimen is not now so illustrative.] The egg is approximately 

 spherical, but departs from a globular form sufiiciently for the differ- 

 ence to be easily seen without measurement. The three diameters are 

 different from each other, the longest is l"16mni., the next, which may 

 be called the breadth, is 1-OOmm., and the height is 0-86mm. The 

 sculpturing is a very fine polygonal network, the lines of the network 

 are raised, with broad flat tops, of a width about equal to a fourth or 

 fifth of the diameters of the polygons they enclose, these are somewhat 

 irregular in form — hexagons, pentagons, and even squares — their dia- 

 meters are about 0-022mm.-0-025mm. The tops of the lines of net- 

 work are nearly smooth, but the flats of the enclosed polygons are 

 occupied by a number of round, nearly hemispherical, elevations, not 

 placed quite in lines, but of such a size that four to six in line may be 

 counted across one of the spaces, and so each polygon is occupied by 

 18 to 35 or so of these knobs. The size of the meshes of the network 

 is so small, and the lines of ribbing or network so flat and little raised, 

 that, without considerable magnification, the egg appears to be quite
