REPLY TO DR. DYAR’S. NOTE. 
By A. Radcliffe Grote. 
In reply to Dr. Dyar’s note, this Journal, V, 66, I would state that, 
having no preparations of the larvae, I may have failed to follow en¬ 
tirely Dr. Dyar’s remarks and any misstatement of them has arisen in 
this way. I would suggest that Dr. Dyar figure them in outline as I 
have done with the neuration. I consider the “ stinging spines ” as 
adaptive, secondary characters, unfit for classificatory purposes of this 
nature and not decisive of phylogeny. With regard to the anal tuber¬ 
cle, Dr. Dyar regards it as primary—of this I cannot judge, but natur¬ 
ally accept this dicta. And this is the only main point. I regard the pat¬ 
tern of neuration as “ primary ” and that it unites, in one phylogenetic 
group, Hemileuca and Saturnia and Automeris and Agha. As to other 
characters, the structure of the female antennae appears to fall in very 
well with my classification as also the specializations of the pupal en¬ 
velop. This whole case seems to converge into: anal tubercles vs. pat¬ 
tern of neuration. It is a test case and should be settled before we go 
any further. It appears to me a physiological impossibility that Agha 
should be derived from the Saturnian branch or that Hemileuca should 
be derived from the Aglian stem. From his point of view Dr. Dyar 
thinks the reverse and hence a settlement of the controversy, which 
should not be suffered to run into side issues, is very desirable. 
surmise as to the identity of Z. canadensis , H. S. with Z. asylas of Cramer met with 
their approval. I have just received the following reply contained in a letter written 
January 1st, 1898. 
“As desired, we have looked into the identity of Zeuzera asylas Cram, and Z m 
canadensis H. Sch., and have come to the conclusion that you are quite correct in 
the belief that both figures represent the same African species. We have nothing ap¬ 
proaching it from any temperate country and all the species of this type appear to be 
inhabitants of the tropical parts of the old world.’ ’ 
I accept it then as established that Zeuzera canadensis H. Sch. is a synonym for 
Z. asylas Cram., and the species should be stricken from our lists of North American, 
species. Herrich-Schaefer’s locality “ Quebeck ” was evidently an error.
