■well-marked vertical ribs, which are carried right up to the outer 

 •edge of the micropylar area, and with numerous faint lateral rungs 

 between. The micropylar area is smooth, somewhat bulging, and 

 ■occupies the whole of the top of the egg. Colour pale yellow. 

 Maximum diameter -Gomm., and height -Smm. 



Apinthof/iaptis luteolata lays small batches on leaves and twigs of 

 hawthorn, etc., sometimes in a row side by side. I have one batch 

 of thirteen laid on the bye-pass key of a street lamp. They are 

 broadly oval in shape, inclining to be rectangular, flattened, and 

 with"^the shell covered with minute pits. The colour is pale yellow, 

 and red spots or blotches develop irregularly over the surface soon 

 after being laid, if the eggs are fertile. Found in Msij and June. 

 Length -Tmm., width -Smm., and thickness -SSmm. 



AnisoiAeryx ascularia. — I have several times come across the 

 curious egg-batches of this insect on hawthorn and sloe bushes 

 when searching for larvae in March and April. They are neatly 

 arranged in rows, closely packed together round the twig, and are 

 carefully covered over with hairs from the anal tuft of the parent. 

 As they appear to be attached to each other end to end, and to the 

 twig by one side, they must be classed as flat eggs. The shape is 

 spherical, slightly flattened at the ends, and with little or no 

 sculpturing on the shell. Colour, golden brown. Diameter -Gmm. 

 and thickness -Smm. 



Ni/ssia zunaria. — The only wild laid aggs of this species I have 

 had for examination were laid in a batch, down inside the fold of a 

 withered grass shoot. They were tucked away into the space avail- 

 able, with no appearance of arrangement or order, and numbered 

 85 in all. They were found in April. The egg is of the flat type, 

 oval in shape, and rather wider than its thickness. The colour is 

 pale green, darkening somewhat as development proceeds. The 

 surface of the shell is rough, being evenly pitted all over. Size 

 •9mm. long, -Gmm. wide, and -Smm. thick. 



Ematiirtfa atoniaria. — I have found these ova in June, on dead 

 flowers of heather, often in small batches, several eggs being tucked 

 away inside one floret. They are flat, oval, rather tapering towards 

 •one end, and have a roughened shell due to sculpturing in the 

 form of longitudinal rows of small pits all over. Colour yellowish- 

 green. Length -Gomm., maximum width •4mm., and thickness 

 '85mm. 



Trochilium crabrunifuniiis. — I once found a small batch of eleven 

 eggs of this species on the bark of a poplar-tree. They were laid 

 in two groups of six and five respectively, in adjoining crevices. As
