segments, the two anal segments and also the six following the 

 head shrivelling up. 



The segments containing the cocoon are somewhat distended^ 

 so that the indurated skin takes the form of a crescent. This 

 construction is very firmly attached to a twig with the natural 

 glue I have already mentioned. Unlike some of the species 

 which weave nothing worthy of the name of cocoon within the 

 hardened skin of the host, grandls constructs a distinct, though 

 flimsy, pure white silken lining which is easily detached. In 

 the New Forest this is certainly not an uncommon parasite of 

 Amphipiira pyramidea ; the host larva is killed when rather more 

 than half grown, and my experience would seem to point to the 

 later cateVpillars only being attacked, though, of course, it is 

 possible that parasitised larvfe feed up less rapidly than their 

 more fortunate fellows. 



Cruentus, Nees.* 



A large, robust species with rufous thorax, the second 

 discoidal cell only half as long as the first, and antennse shorter 

 than the body. 



The only British specimen hitherto recorded was taken by 

 Morley on the Norfolk Broads in August, 1911. A very fine 

 female captured by Harwood near Colchester some few years ago 

 and now in his collection has 57-jointed antennse, and measures 

 9 mm. in length with an expanse of 15^ mm. The species is 

 said to have been bred on the continent from Dianthcecia 

 cucubalL 



Rugulosus, Nees.t 

 Another fine species not hitherto recorded as British. It has 

 the second cubital areolet subquadrate, and the third abdominal 

 segment strongly punctate at the base and longitudinally striate 

 towards the apex. In 1914 Col. C. G. Nurse sent me four 

 reared by him between June 20th and 23rd of that year from 

 Wicken larvte of Arsilonche alhovenosa. They were accompanied 

 by their cocoons, by which it could be seen that the host larv8& 

 had attained to something approaching half growth before 

 succumbing. Only the central segments of the caterpillars had 

 been made use of in constructing the cocoons, which greatly 

 resemble in shape those of R. firaiidis. On the continent it is 

 recorded as having been reared from Acronycta euphorhne and 

 A. abscondita. 



Prcetor, Rein.^ 



Probably the largest species we have and quite easy to 

 identify. Bright testaceous, with only the antennae (except
