80 THE CANADIAN ENTOMOLOGIST. 



Dear Sir : In connection with the article entitled " The Colias Con- 

 troversy," by Mr. R. H. Stretch (Can. Ent., vol. i8, p. 54-56), I would 

 like to call attention to the fact that early in the year 1884, Mr, Stretch 

 wrote Mr. W. H. Edwards that he knew nothing about the " purposely 

 prepared" CoHas (cf. Papilio, vol. 4, p. 170), but that on the 9th of 

 December, 1885, he requires about two and a half pages of printed mat- 

 ter " to state in a concise manner " what he knows about it. Mr. Stretch 

 quotes from his note-book, ^'- July 4th,* took very fine series of Colias 

 (3 forms)," and adds, "it" (the specimen under discussion) "might 

 have been either one of these or some other." The " purposely pre- 

 pared " Colias was taken at Umatala, June 25, so that we can all agree 

 that it was " some other." Under the circumstances, I am unable to hold 

 in high esteem Mr. Stretch's assertion that I have stated " the case 

 exactly," or allow that he is able to add any facts to " The Colias Con- 

 troversy." Saml. Henshaw. 



OUT EARLY. 



Dear Sir : Belostoma Americanum, the " Electric Light Bug," as it 

 is popularly called here, and its usual companion, Dytiscus jnarginalis, the 

 " Water Tiger," were out abundantly this evening at the electric lamps, as 

 last summer. The toads also put in an appearance at the same time and. 

 place as they were accustomed to do last year. E. W. Claypole.

instance of retarded development, AUG. IITH, 1 883, CASSIA, FLA. 



Dear Sir: About June 15th, I collected nine chrysaHds of Papilio 

 cresphontes from orange trees. They were newly made. From June 22nd 

 to June 27th all but one gave imagines; this, on subsequent examination, 

 was found to be alive, and (Aug. nth) gave also its imago, a large $, 

 thus being retarded in development about 45 days — the conditions of 

 environment being the same for all.
