paper had cleared away all distinctions between the two 
forms. Mr. Bacot said that he had bred both species, and 
noted their distinctions very minutely. The larve were 
absolutely identical until after the third moult. Then 
T. biundularia had a V mark, but the point of the V was 
very distinctly open. T. crepuscularia also had a V mark, 
but this was nearly always closed, and the point consider- 
ably produced. Occasionally a gap did occur in this species, 
but it was never so wide as in T. biundularia, and always 
undoubtedly distinguishable. 
Mr. Hewett in reply said that he entered the discussion 
without prejudice, with the idea of unveiling the truth. He 
would say in reply to Mr. Bacot that Dr. Riding asserted 
that careful examination of the larvz showed no distinctions 
whatever. He thanked those gentlemen who had so readily 
come forward to his assistance, and expressed the pleasure 
it had been to him to read his paper before the Society.
