50 THE ENTOMOLOGIST. 



that this species, in common with so many of the Tortrices, goes 

 through the greater portion of its larval existence in the autumn. 



A suburban garden does not at first sight seem a promising 

 scene of action in which to work out the life-history of a species 

 of which so little is known as is the case of C. unfascicma, but I 

 have known for some years that mine contained a fairly numerous 

 colony of this moth, and was therefore a favourable ground for 

 the purpose. This colony seemed centred amongst the fruit 

 trees of the kitchen garden, adjacent to which, however, were 

 a number of forest trees, and not having looked up what was 

 known of the larval habits, I at first assumed that the chosen 

 pabulum was the leaves of one or another of my fruit trees, and 

 females were netted and confined each year over sprays of all 

 those growing near when the individuals of the colony flew, 

 with an entirely negative result so far as the obtaining of ova 

 was concerned. In the year 1918, however, I found the moths 

 flying at dusk abundantly over a short privet hedge in one 

 corner of the kitchen garden, and this year the females obtained 

 were confined over sprays of this shrub. 



The result was that ova were deposited freely, and the resultant 

 larvae were reared without difficulty on its leaves. 



In my first attempts to obtain ova I confined the females 

 over apple, pear, plum, hornbeam, elm, oak, birch and Clematis- 

 vitalba. The successful attempt included, as well as privet, 

 golden rod and loganberry, both of which grew near by. This was 

 on July 28th, 1918. On August 1st, on examining the plants^ 

 I found six clusters of ova, all deposited upon privet leaves ; 

 these clusters each contained from six to twelve ova. They were 

 all fixed to the upper side of the leaves on the midrib ; each 

 ovum in a cluster overlapped the others, or was overlapped^ 

 as is usual in this group. 



The ovum is a very beautiful object ; it is silver-grey in 

 colour, not opalescent, but slightly glabrous. The surface con- 

 sists of a large number of figures divided by fine raised margins^ 

 as is usual amongst the Tortricidte, but the hind margins are 

 bolder and the figures are more uniform in size and shape than 

 any other Tortrix ovum with which I am acquainted. It is 

 circular in outline, about "83 mm. in diameter, and is evidently 

 very fluid when deposited, for there is a platform of the envelopes 

 around the clusters. This platform is about '17 mm. in width. 

 The ova themselves stand well up above the leaf to which they 

 are affixed — about '2 mm. above it. 



On August 4th the ova had a distinct nucleus, ochreous 

 yellow in colour, circular in outline, and for size about half the 

 extreme diameter of the ovum. Six days later the whole ovum 

 was reddish -brown in colour. 



Oo August 12th the larvae— or most of them — emerged. They 

 were 1'65 mm. in length. The head and prothoracic plate was
