Orleans cotton exposiiion of 1S84-5, '^'•''^ '^^^ investigations by Professor 

 Morgan show that it is most prevalent in an orchard into which citrus 

 plants from Brazil have been introduced, and that from this nursery nearly 

 all the orange plants in the City of New Orleans have been sent out. 

 This indicates a South American introduction into Louisiana independent 

 of the West Indian introduction into Florida. Late advices show that it 

 has established itself at Galveston Island, Texas. We have also seen 

 specimens from Tampico, Mexico. 



STAPHYLINUS CESAREUS, CEDERH., AND S. ERYTHROP- 



TERUS, LINN., IN CANADA. 



BY W, HAGUE HARRINGTON, F. R. S. C., OTTAWA. 



Staphylinus erythropterus, Linn. This beetle has been but once 

 recorded in America, the specimen being noted from Detroit. I have 

 now to record it as inhabiting this section of Canada, and, at the same 

 time, to correct an error which has been put in circulation through my 

 agency. When Dr. LeConte visited me in July, 1883, he named a beetle 

 for me as S. ccesareus, Cederh. {ornaticauda, Lee), remarking that it has 

 only Dnce been found in America. The species was, therefore, inserted 

 in my list of Ottawa Coleoptera (Ott. Field. Nat. Club, Trans., vii., p. 191), 

 and in my Additions to Canadian Lists of Coleoptera (Can. Ent. xvi., p. 

 46). These records are quoted by Dr. Hamilton in his catalogue of the 

 Coleoptera common to North America, Northern Asia and Europe. The' 

 capture of examples of S. badhis (not on my list) proved to me that a 

 slip had been made by Dr. LeConte (his examination of my collection 

 having necessarily been hurried), and that the insect labelled ccesareus 

 was only really badipes. I, therefore, determined to strike the name off 

 my list, and to take the first opportunity of correcting the error, but soon 

 after, by a curious coincidence, I found (Apl. 23rd, 1892) under a stone 

 at the margin of a swamp a Staphylinus, which seemed to be a genuine 

 ccesareus. My determination was made by Dr. Horn's monograph of the 

 genus (Trans. Am. Ent. Soc. vii., p. 191), in which, following the descrip- 

 tion of the species, he says : — " Easily known from every other species at 

 present occurring in our fauna, by the spots of golden pubescence at the 

 sides of ventral segments above and beneath." On informing Dr. Hamil- 

 ton of my capture, he kindly sent to me a ccesareus from Europe for com- 

 parison. This was much larger, and had the elytra more pubescent, and 

 the abdomen more coarsely sculptured and hairy, giving the beetle a coarse
