depressed, the surfaci' very minutely pitted. Len,i,'th : breadth : height 

 apparently about 5:1:3. No further structure to be made out. 

 [Laul by $ taken at Chamonix, August 1-lth, 1902, described August 

 17th, 1902. J— J. W. TuTT. 



Anthrucera e.culans. — -Rather pale yellow ; almost regularly oval 

 except for a slight flattening at one end ; length : breadth as about 



: 8-^, the height apparently almost equal to width, the k^gg being very 

 full, without any depression, also uniformly yellow throughout, without 

 any pale pole as in the eggs of some other Anthrocerids. Surface 

 somewhat shiny, apparently finely pitted ; eggs laid regularly m rows 

 naturally, often in heaps in confinement. \]^gg laid August iHth, 

 1902, by a $ from the Montanvert. 



( rainbas niucheUus. — Small for size of moth ; oval iii outline, except 

 that one pole is slightly flatter than its nadir ('? micropylar); the length 

 : breadth as about 5:1; the longitudinal ribs well marked, four seen 

 on upper surface when egg is lying Hat on table, faint transverse ribbing 

 crossing longitudinal ribs at right angles. Laid loosely. 'Eggs laid 

 August 19th, 1902, by J taken same day on Brevent, at about 6700ft. j 



These eggs were described simply with a good hand lens, the only 

 apparatus I had with me at the time. — J. W. Tutt. 



Boarniia rlwiiiboidaria{<jeiiniiaiia). — These eggs are laid in batches of 

 from 5 to 12 on the small twigs of the foodplant. They are attached to 

 one another side to side, leaving the micropylar end uppermost. The egg 

 is remarkably beautiful and represents a high stage in the development 

 of the Geometrid group. Its shape is cylindrical, twice as long as 

 broad, and rounded off' equally suddenly at both ends. In colour it is 

 l)right arsenic-green when first laid ; three days after patches of pink 

 of a glorious shade appear. At the end of seven days the colour of the 

 egg was bright pink, slightly mottled with olive-green. On the tenth 

 ilay the whole was a dull slate-colour, and on the 12th day it hatched. 

 The egg is beautifully regular in shape, with a hard surface, not shiny, 

 except at each rib. These ribs are accurately vertical and horizontal. 

 The vertical ribs are very strong and thick. The horizontal ribs are 

 very sharp and ihin. There are 26 vertical ribs at the equator, only 

 fourteen of which run up to the stellate area, and there are 26 trans- 

 verse ribs from base to stellate area. The stellate area is truly 

 Geometrid in form, very large, and consisting of the usual honeycomb 

 pittings, with beads at the junction of each rib. These beads are very 

 large and very glowing white in this species. The micropyle is fairly 

 large in proportion to the egg and has nine curvilinear petals rapidly 

 descending to the central crater. The measurements of the egg are 

 given in mm., those of the micropyle in /m/a. (micro mm.), and are as 

 follows : Egg — total length, -oimm. ; total breadth, •27mm. ; 

 diameter of stellate area, •24mm. Micropyle — diameter, 50/^/y.; 

 longest petal, 21//)a. ; shortest petal, 23//-/U. ; diameter of central crater, 

 2-5/x/x. Described under |" obj. lens with 12" lens eye-piece on 

 August 4th, 1900. 



Zeuzeia pi/iina. — This egg is laid in a very irregular manner, 

 pushed by the ovipositor into crevices in the bark, and so frequently 

 crushed out of shape. In such cases the eggs are laid in a mass, but 

 where there is more room they are laid in long strings of from eight to 

 ten, some of them attached end to end, some side to side, and some 



1 ven end to side. In all cases they are a little crushed. The egg is
