PHYCITID/E—DIORYCTRIA 417 



Pupa apparently undescribed. This state is not, I think, 

 assumed in the fir cone in which the larva has fed. 



But little is known among us as to the habits of this 

 species, indeed it is itself not very generally recognised. 

 In 1877 and 1878 the habits of its larva were carefully 

 worked out in Herefordshire by Dr. J. H. Wood and 

 Mr. Buckler, under the name of ahietel/a, and ten years 

 later the details were published by the late Mr. H. T. 

 Stainton, with the remark that they seemed to be referable 

 to the present species. That is undoubtedly the case — two 

 of Dr. Wood's specimens are now before me. In 1887 a 

 larva was obtained in Norfolk in a j'oung green cone of 

 Pinus abics, by Lord Walsingham, when collecting those of 

 Cateremna terebrella, and the moth duly emerged in the 

 following June. Before this — in 1885 — attention had been 

 drawn in the Entomoloijistii Monthly Magazine to this species 

 by the late M. E. L. Eagonot, though without knowledge of 

 its existence as British ; and some suggestions are there 

 made with reference to its larva and habits ; yet, reluctant 

 though I am to dispute the accuracy of so high an authority 

 upon the present group, it seems impossible to escape from 

 the conclusion that he transposed the larvtc of the two 

 species. 



In June 1888 the Rev. C. T. Cruttwell drove me over to 

 Southwold, on the coast of Suffolk, and there, close to the 

 sea, in a district devoid of fir-trees of any kind, we secured 

 six specimens of this species — one by beating a hedge, 

 and the rest hiding under the edges and chinks of some 

 wooden buildings. Every inquiry was made as to possible 

 means for their introduction to this particular spot, but 

 without result, and the only feasible explanation seemed to 

 be that a small partial migration had taken place. A similar 

 explanation seems to account for the capture by Mr. J. 

 Gardner of a specimen flying over flowers at Hartlepool, 

 Durham. The insect is now becoming common in the New
