. THE CANADIAN ENTOMOLOGIST. 99 



Prof. Riley, but I refer to my statements in print and to the fact that the 

 line of continuous breeding is yet unfixed, while it is the primary object 

 to be ascertained by practical entomologists. On page 56 of this volume, 

 Mr. Smith "dissents from the idea" that certain Sphingidas or Hawk 

 Moths determined from our territory by Mr. Edwards should be taken 

 into our fauna in papers on our fauna. He demands that the right 

 should be made clear by ascertaining that the insect breeds within our 

 territory. I agree with Mr. Edwards that we should take all species 

 found within our territory into our lists and treat them as belonging to 

 our southern fauna, until it is proved that they do not breed with us ; 

 and then with the remark that they do not breed, but are merely wind- 

 visitors as moths. How can we pass over such a fact, as their being 

 found with us, in silence? Again, seeing the large extent both of our 

 territory and of our ignorance of the conditions under which our moths 

 live, how can we pronounce whether or no these moths may not be 

 summer breeders, or occasional breeders ? Who knows that Philampelus 

 typhon does not breed seasonally in Arizona ? Mexican moths are 

 probably more often found in Texas than we have yet any idea ; and 

 Cuban in Florida. Mr. Roland Thaxter has bred the Spanish moth, 

 Euthisanotia timais in Florida. This is quite a pronounced tropical 

 form. The moth in numbers is beaten by the wind into the light-houses 

 on the coast at least as far north as New Jersey, probably much higher 

 up. We must keep a busy record of the habits of these moths to under- 

 stand their geographical distribution and their habits. Any ignoring of 

 them in monographic works will tell against the completeness of such 

 works, while the moths, unhindered by the defects in our literature, will 

 wing their way northward and become at least adopted citizens of our 

 domains every summer. As to the Hawk Moths, the Blue and Green 

 Hawk (labruscce) has been taken in Missouri and in New Jersey. 

 Tropical species of the Owlet Moths allied to Erebus odora have been 

 taken so far north as Wisconsin, coming up the valley of the Mississippi. 

 I refer the student to my general paper on the Geographical Distribution 

 of our Moths in these pages, and I earnestly hope that all our wind- 

 visitors will be catalogued, described and put on record, since it seems 

 to me we can get no complete picture of our fauna without them. The 

 limit of their continuous breeding must be ascertained, as also of their 

 summer migrations. Do not our ornithologists take into their works and
