134 THE CANADIAN ENTOMOLOGIST. 



knowledge regarding this interesting subject, for the tree-cocooning habit 

 in this instance seems to be rather abnormal, and raises the question as to 

 whether it is in that locality rather behind in adopting the terrestrial habit 

 of cocooning, or in advance in abandoning that and adopting that of 

 cocooning in the trees inhabited by the larvae. This will also aid Mr. 

 Cockle in solving his equally interesting puzzle as how to account for the 

 same insect in his locality cocooning after the manner of C. promethea. 

 And this last gentleman can also do science a lasting service if he can 

 throw any light on the interrelation of the species and the woodpeckers in 

 his locality. We have in these notes some very interesting facts relative 

 to the habits of some of our common species of Attaci, but we cannot 

 without further observation and more facts decide whether these 

 phenomena are due to natural selection and a change of habit or whether 

 they are perplexing coincidences. Then, too, possibly others may have 

 some observations to offer that will help us in getting more light on the 

 subject. 



A COUPLE OF QUERIES. 



BY REV. G. W. TAYLOR, WELLINGTON, B. C. 



In his Monograph of the Geometrid Moths, Dr. Packard described 

 and figured two moths as Metanema quercivoraria, Guene'e, and 

 E7idropia textrinaria, Grote and Robinson. He placed them in 

 different genera and had apparently no doubts as to their distinctness. 



With regard to M. quercivoraria (page 544), he does not state what 



material he had before him, but his figure, pi. XII., fig. 39, clearly 



represents a female with simple antennae. In giving the dimensions of 



the moth, however, he speaks only of the male. Packard suggests that 



M. aeliaria of Walker may be a synonym, and Hulst (Ent. News, VI., 

 14), from an examination of the type, confirms this. M. aeliaria was 

 described from the female only. 



M. quercivoraria is also figured by Holland in the Moth-book, pi. 

 XLV., fig. 28, and again it is the ? that is represented. 



Endropia textrinaria was described and figured by Grote and 

 Robinson from the male only. Packard (Mon., 507), redescribes it from 

 3 $ specimens. His figure is also oi z. $ , and he makes no mention of 

 tiie female. 



Hulst, in his "Classification " (Trans. Am. Ent.Soc, XXIII., p. 378), 

 brings the two insects together, placing them side by side in the genus 

 Metanema. 



Both forms have the same range, and both occur with us in British 

 Columbia.
