NOTE ON MR. GROTE!S REMARKS ON THE 
SATURN IANS. 
By Harrison G. Dyar. 
Mr. Grote’s reply to my criticism on his paper “ Die Saturniiden 
is disappointing. I had hoped that he would adopt my suggestion to take 
three or four entirely different characters, work each out independently 
in the same manner as he has done for vein IV 2 of primaries and let the 
evidence from these show whether his classification or mine was the 
nearest the natural one. Instead Mr. Grote defends his classification 
on the original grounds and misstates (unintentionally of course) and 
belittles the larval characters. The matter is certainly simplified by 
“setting down the loss of the pair of anal tubercles solely to the Cither- 
oniinse.” The only objection that I know to this ingenious solution 
is that it is not a statement of fact. But, seriously, it remains that the 
genealogical tree deduced by Mr. Grote is contradictory to the one that 
I have made on larval characters. My original statements are not af¬ 
fected, so far as I can see, by Mr. Grote’s insistance on the importance 
of his characters; it is open to me to insist equally on the importance 
of mine. Collateral evidence only can decide the question, and this 
Mr. Grote has not adduced. In reply to Mr. Grote’s kind wish to con¬ 
vert me to his views, I again point out the path to that end, or at least 
the path which must lead to the end of a mutual agreement, whether on 
Mr. Grote’s system or mine, or some other more natural one, which we 
neither have thought of.
