of Gracillaria swederella this is particularly noticeable (PL II, 

 fig. 6). 



Bred from Paramcsia ferru/fana, October 23rd, 1914 ; 

 G. swederella, November Ist, 1915 ; and many times from 

 LWiocolletia cori/li, October lOtli to November 1st ; also from a 

 species of LitJiocolletis mining tlie under side of oak leaves. As 

 a hyper-parasite, I have obtained a chalcid named by Morley, 

 after comparison with the type in the British Museum, as 

 Eulophus eneuganms, Walker. 



A. callidus, Hal.* 



Distinguished from lateralis and vitnpennis by its dull 

 granulate coxae and narrow wings. 



I have never captured or bred this insect, the only specimens 

 I have seen being an ancient pair, without data, in Harwood's 

 collection ; probably they were at one time in the possession of 

 Fitch. Is recorded by Bignell as a gregarious parasite of 

 Abraxas grossulariata, but, although I have at various times 

 reared some hundreds of the larvte of this moth, and have 

 obtained ruimerous parasites of other species, A. callidus has 

 never occurred to me. 



A. lateralis, Hal.t 



Very similar to vitripennis, but differing in the rougher 

 metathorax and also the exserted terebra, which in this species 

 is almost half as long as the abdomen. Marshall tells us the 

 first abdominal segment is " almost smooth," although Haliday 

 says it is '^ punctulatum" 



I have found it to be a very common parasite of Sericoris 

 fahricana, preying on both spring and summer broods of that 

 insect. Harwood has a single specimen formerly in Fitch's 

 collection, and labelled by the latter, "Ex. S. fabriciaiia ?, 

 20/9/83, W.H.B.F." 



The cocoon is white and similar to that of vitripennis ,- 

 sometimes it is constructed within the well-known web made by 

 the host ; at others on the under side of a leaf of the food-plant. 



A. ritripe7inis, Hal. I 



A rather prettily marked species, the first three segments of 

 the abdomen being very noticeably edged with flavo testaceous ; 

 indeed, in some specimens these segments are entirely flavo 

 testaceous above, with the exception of a central isolated black 

 patch. Bignell tells us that this is often a gregarious parasite, 

 which does not agree with my experience. Marshall also, in
