192 IJanuaiy, 1880. 



species is double brooded, but this may refer only to the times o£ 

 appearance of the perfect insect. 



Grartner describes the larva of this species as " grey-green with 

 " bright yellow head, dorsal plate similar, divided, jaws darker, anterior 

 " feet brown-green. In May in a web on Etqjhorbia amygdaloides, 

 " lucida, and aquatica, boring into the stem. To become a pupa it 

 " leaves its habitation and goes into the earth." 



This does not agree very well with our larvae. I hear, however, 

 from Dr. Wood, that S. euphorhiana is found in the woods of Hereford- 

 shire, where its larva feeds on the w^ood-spurge {E. atm/gdaJoides). 



Sericoris littoralis, Curt. (Jittorana, Dbl.). There appears to be 

 no record by any continental writer of the larva of this species. Mr. 

 "Wilkinson simply says that it feeds on the common thrift, and it has 

 been reared from that plant by Mr. Hodgkinson and others occasionally, 

 but I think that no accurate description has been published. 



In April, 1S78, 1 found, on the coast-cliifs a few miles away, large 

 tufts of thrift (Anueria vulgaris), in which some of the leaves were 

 drooping and turning brown. A careful search enabled me to find the 

 larvae feeding in the hearts of the little shoots which grow close to- 

 gether to form the tuft, or sometimes in a tube of silk among the 

 green or brown leaves. 



This larva is very active, wriggling violently when disturbed, cy- 

 lindrical, colour dull pale greenish-grey, still paler when full grown, 

 spots hardly visible but with distinct hairs, head light brown, jaws 

 blackish, dorsal plate black, anal plate indistinct. 



Pupa light olive-brown, spun up among the leaves of the thrift 

 close to the eaten shoots, emerging in June. This summer (1879) I 

 again reared it from large tufts of thi'ift, generally found in sheltered 

 corners under the rocks at the top of the cliffs, and easily discovered 

 by the patches of dead leaves. 



Before Mr. E. Meyrick left England, he sent me a memoi*andum 

 of the rearing of this species in 1870 by Mr. Jenkinson, a most ener- 

 getic young entomologist, who stated that his larva? fed in the, floiver- 

 heads of the thrift, that they were dark chocolate-brown, and that they 

 spun the florets of the flower head all together in a mass, and assumed 

 the pupa state in a vertical cocoon, placed head upwards, in the spun- 

 up head. This appears circumstantial, and also perplexing, for I have 

 not found the larvae in the flowers at all, but it may possibly be tlie 

 habit of a second brood, which I know occurs on some coasts, but which 

 I have not seen here.
