I do not propose at present to comment upon the foregoing 

 list, but I hope when I have got through the life-histories of our 

 British species to return to this subject, and shall also have a few 

 words to say about the present position of the group in the 

 Doubleday arrangement of British Lepidoptera. 



I said in my last paper that I would describe some of the 

 species in my next contribution, but no doubt your readers will 

 have observed at the head of the Exchange list, in the March 

 number of the ' Entomologist,' that it is intended to give plates 

 illustrative of the descriptions, showing figures of imago, pup^e, 

 larvffi, and food-plant. This will obviously necessitate some 

 little delay in the publication, which will proceed as fast as the 

 necessar}^ material for figuring comes to hand. 



It may be reasonabl}^ assumed, when more observers are at 

 •work on the Pterophori, and the larvae assiduously hunted for and 

 collected, that not only will some of the rarities be deprived of their 

 claim to be considered rare, but a new species or two may be added 

 to our list. As a guide I will refer to three of our rarer and one con- 

 tinental species of Pteropkoridce. The larva of Ptei-ophorus brachy- 

 dactylus is said to feed on Lactuca miiralis in June. I should, 

 however, think it more likely to be found on L. saligna. This 

 latter plant is not of such general distribution as L. muralis, but 

 it occurs in those few places where the insect in question has 

 been taken ; therefore I shall not be considered to draw 

 rash conclusions if I suppose the restricted range of P. brachy- 

 dactylus to be due to its predilection for the scarcer species of 

 Lactuca. I well know that "plume" larvae found upon one 

 species of a tribe of plants will also frequently feed upon other
