facies. Still, ihe difference was not nearly so marked as the variations 

 found in many of our beetles, and, relying upon the golden spots upon 

 the abdomen as the test of the species, I remained of opinion that my 

 insect belonged to it. 



On October 27th last, Mr. Fletcher and I made a hunt in Dow's 

 Swamp (near the Experimental Farm), on the borders of which I had 

 found the specimen in 1892, and while digging around the roots of trees 

 for such beetles as might have gone into winter quarters, it was my good 

 fortune to obtain two specimens, and around the same stump were taken 

 about a dozen examples of hadipes. Both specimens when alive showed 

 beautifully the golden spots on the abdomen, but when they were taken 

 out of the bottle of sawdust, in which they were killed, it was found that 

 the spots had mostly been rubbed off. With this new material I was 

 anxious to definitely settle the question of species, and accordingly sent 

 one to Dr. Hamilton, who replied that : — " The insect you sent is a good 

 example of S. erythropteriis. I have five examples of both eryth'opteriis 

 and ccesareus from Sweden, and there is no difficulty whatever in the 

 determination by comparison. Ccp.sareus is much larger, and has the 

 thorax and head much more coarsely punctured. The golden abdominal 

 spots are about the same in both, but seemingly more readily lost in 



erythropterus, one half of mine having them about as in yours." 



An early fall of snow prevented us from searching for more material 

 until ■to-day(Nov. 17th), when I spent about two hours carefully searching 

 in the swamp, which was very wet, and more or less covered with snow, 

 and was rewarded by obtaining one specimen, also at the root of a tree 

 under moss, etc., four or five inches beneath the surface. 



The American record for S. erythropterus will, therefore, rest on the 

 specimen from Detroit, U. S., and my four specimens from Ottawa, Can,, 

 the species being apparently able to perpetuate itself in this country, and 

 inhabiting swamps. 



The record for 6". ccesareus will rest on Mr. Ulke's example taken in 

 Canada (locality not quote 1), and possibly that specimen, if re-examined, 

 might prove to belong to the preceding species. 



I regret that Dr. Hamilton's new edition of his catalogue is printed, 

 and that, therefore, the records therein cannot be amended.
