190 THE CANADIAN ENTOMOLOGIST. 



lists after species unknown to me in nature. In my paper in July No., 



the locality, " West Coast," belongs to the preceding species perelegans, 



and a dash should follow Vancouverensis, as to the synonymy of which, as 



well as its validity as a species, I was indebted to Mr. Hy. Edwards for 



information. As will be seen by the absence of the dash after perelegans, 



as well as the wrong position given by me to Vancouver etisis, the locality 



has been misplaced, as I give no locahty to species unknown to me in this 



last list. Mr. Edwards quite naturally was our authority as to the Cali- 



fornian species. Since Mr. Butler considers the various Asiatic forms of 



Triptogon as local, rather than true species, I thought it might be so with 



Occident alls ; but it may well be a mere variety, as Mr. Holland considers 



it. If I remember, Mr. Edwards originally described it as a geographical 



variety of modesta, which may be true if no typical modesta occur in 



California, and although this var. occidetitalis may also be found in the 



East. This species will have then received four names (two applied to 



varieties) since Cablei from Louisiana, the larva on water plants, seems 



nothing but modesta, which its author did not know. 



Mr. Holland's note on Hemaris uniformis is exceedingly opportune ; 

 from the data it may well be that it is a more northern form. But, if so, 

 what are we to make of Mr. Hulst's assertion (for he had no material) 

 that Floridensis is a large variety of Thysbe ? — naturally, of course, of 

 uniformis, for the band is not dentate in the Florida species. And why 

 do we not find dentate Buffaloensis ? if this is only a " small " variety, 

 naturally, also, of uni/ormis. That Prof Lintner describes the larva of 

 Buffaloe7isis and appears to regard it as distinct (in letters Prof Lintner 

 kindly informed me he considered the imagos distinguishable) does not 

 seem to have had any weight with Mr. Hulst, whose discovery of the 

 relationship between uniformis and thysbe seems to have affected his 

 proper study of these forms. I believe we may find that these are distinct 

 species. 



In view of this paper of Mr. Holland's, my list in July No. must be 

 amended by referring occidentalis. No. 54, as a var. to modesta, No. 53. 

 Further, No. 79, oreodapJme Hy. Ed., may be referred as a var. min. to 

 No. 78, chersis; while the position of No. 82 must be changed to follow 

 No. 76, drupiferarum, the name followed by a dash, as I do not know 

 the species of which Vashti may well be a synonym, as Strecker's figure 

 of Imperialis does not also quite agree with specimens of occidentalis, yet
