THE CANADIAN ENTOMOLOGIST. 287 



Riley might have confused two or more species, as that has been done by 

 many eminent entomologists, but to make figures with sufficient latitude 

 to include such distinct species as Hyphantria Punctatissima and Spilo- 

 soma Antigone would be much less excusable. I certainly appear to 

 have misunderstood Dr. Fyles on one if not two minor points. It is 

 strange that so many of us have misunderstood him. \A'hile I am con- 

 siderably younger than Dr. Fyles, which, however, is hardly releVant to 

 the controversy, I am perfectly aware of the meaning of " bilateral 

 symmetry," and in my copy of Smith & Abbot the figures of Punctatissima 

 are perfectly symmetrical and not at all as described by Dr. Fyles. 



But when an author illustrates the larva of a species on its food- 

 plant and figures the perfect insect on the same plate, does he really 

 thereby imply that all stages are to be found on the same plant at 

 one time ? And might Mr. Edwards's magnificent plate of Melitsea 

 Phaeton in But. N. A., Vol. II., be therefore properly described as 

 " quite a fancy sketch "? 



It is quite true that I have never had Dr. Fyles's specimen in my 

 possession, he having refused to allow me to take any of his specimens to 

 compare with Walker's types in the British Museum, but I have seen it 

 several times as well as other specimens of the same species which I 

 have seen in several museums which I have recently visited, and I have 

 had Mr. Winn's two specimens of the same form in my possession for 

 weeks together, he having kindly permitted me to carry them to New 

 York, Philadelphia and Washington, and just recently to the British 

 Museum. 



Internal and external are antithetic terms, but superficial was 

 quite properly used by me to denote a slight general resemblance in 

 maculation which, however, in my opinion disappears upon a more care- 

 ful study of the details. Henry H. Lyman.

Sir, — July 6th was a very hot day in Orillia, over go° in the shade, 

 and the night still remained very warm. I, as usual, was at my favourite 

 occupation of collecting ; I had made several trips to the places which I 

 keep regularly covered with rum and molasses during the season. This 

 evening there was literally no standing room for the myriads of moths 

 which crowded each other to get at the sweets. Hadena ardica was 

 swarming — never saw so many in my life, and I have had quite a Iq'h
