DESCRIPTION OP THE EGG OF COLEOPHORA 

 M UR INIPENNELLA . 



By T. a. Chapman, M.D., F.E.S., &c. 



Eggs of Coleophora murinipennella, laid in heads of Luzula 

 campestris, were received from Mr. A. Sich on May 17th, 1901. 

 The eggs are deposited at the base of the flower (or fruit) outside 

 the perianth, within the scale or glume from within which each 

 flower arises, occupying the little hollow between the scale and 

 the flower-stalk, if so short a stem can be so called. 



The egg is white, with pearly lustre. They vary a little in 

 size, from a length of 0'26 to 0"33 mm., and a width of 0*15 to 

 0*19 mm. These measurements may be to some extent in error, 

 since the egg is a very soft one, and moulds itself readily to the 

 position in which it is laid, and also appears to dry readily, and 

 show various hollows in consequence. Eggs placed in water for 

 a minute or two rounded up, and measured the full sizes just 

 noted. In looking for any sculpturing, the first things observed 

 were some very definite striae, very unlike, however, any ordinary 

 egg-sculpturing. These proved to be the impressions received 

 from the veins of the glume, within which the egg is laid. The 

 long axis is the micropylar one, and the other two were not 

 detected to be different ; no surface sculpturing was detected. 

 The micropylar area is a raised mammilla, about one-ninth of 

 the width of the egg in diameter, i. e. rather less than 0"02 mm., 

 and of half this height, or barely so. The whole so transparent 

 that its resetted structure was not very clear, but appeared to 

 give the little prominence a scolloped margin.
