some 24-28 longitudinal ribs are recognisable, but so closely crossed by 

 transverse ribs at right angles as to almost destroy their character. About 

 twelve of the ribs come over the shoulder of the egg and die off in the 

 micropylar depression at the apex. The micropylar area is well- 

 defined, the micropyle central and forming a small stellate depression.

 Mr. Bacot, who will report on the eggs later. The difficulties attending 

 the Cossid egg have already been pointed out, antea, vol, xii.,

Notes on Eggs of Lepidoptera. — The following notes, made whilst 

 away from home, and without any proper appliances for making 

 detailed descriptions, are simply intended to supply certain lacunae in 

 our knowledge until more satisfactory descriptions are available. After 

 dealing with them I posted the eggs on to Mr. F. Noad Clark for the 

 purpose of photographing (but have since heard that at the time of 

 their arrival Mr. Clark was from home, and by the time he had 

 returned most of them had hatched). The eggs were all examined 

 under a two-thirds lens used as an eyeglass : — 



(Eneis aelln. — The egg is upright, circular in transverse, almost 

 oval in longitudinal, section, but rather flattened at base. Height : 

 width as about 5:4. Pale pearly-yellow (almost pearly- white) in 

 colour, with the micropylar area very distinctly marked off' at the apex 

 of the egg. The longitudinal ribs, eighteen in number, are very 

 distinctly marked, shining almost like silver in reflected light, and 

 appear to be wavy, this appearance being probably due to a number of 

 inconspicuous transverse ribs which seem to surround the egg and 

 cross the longitudinal ribs ; only in one instance do two of the longi- 

 tudinal ribs unite before passing over the shoulder of the egg, 

 most of them running quite separately over the shoulder, ending, 

 as ribs, on the margin of the apical area ; on the apical area they 

 appear to break up into series of raised points, finally forming a sort of 

 ring round the micropyle proper at the summit of the egs'. [Described 

 on August 17th, 1903, from an egg obtained by dissection of the body 

 of a $ captured the preceding day at AroUa.] 



Hpini'j/lieli' li/caon. — Yellow, inclining to orange, in colour; in shape 

 a truncated cone, rounded at the bottom ; height, very little more 

 than diameter ; 20 or 21 well-defined longitudinal ribs, extending 

 from base over the shoulder of the egg ; apical area flattened, with 

 a depressed ring just within the termination of the longitudinal ribs ; 

 the central area somewhat articulated, the immediate area around the 

 micropyle slightly raised ; no transverse ribs to be detected with the 

 power at disposal. [Described August 15th, 1903, from eggs dissected 

 from body of a $ taken at Useigne, August 13th.] 



Melainpias nielaiiipKH,- The egg is upright, of a pale creamy tint, 

 circular in transverse, and somewhat oval in longitudinal, section, but 

 rather broader at the base than at the apex, which is somewhat 

 flattened to form the micropylar area. Several (about 28) fairly- 

 marked longitudinal ribs run from apex towards shoulder, where many 

 anastomose, chiefly in pairs, and curve round into the apical area ; 

 this area (around the micropyle proper) appears to be minutely pitted, 

 but the structure of the micropyle is not to be made out under the 

 power at disposal. [This note was made August 10th, 1903, from an 

 egg obtained by dissecting a J captured at Arolla on August 8th.]
