94 THE CANADIAN ENTOMOLOGIST 



SOME RECORDS OF CANADIAN MYRIOPODS. 



BY RALPH V. CHAMBERLIN, 

 Cambridge, Mass. 



These notes are based upon a small collection of chilopods and diplo{)ods 

 chiefly from the region of Ottawa and Quebec City, Canada, made by Mr. 

 Frits Johansen and by him sent to me for identification. The collection is 

 especially interesting in containing representatives of two European diplopods 

 not previously known to occur in America, Blaniiihts giiihdat-us and Julus fallax. 

 It seems desirable to place on record this first known appearance of these forms 

 on this side of the Atlantic, occasion being also taken to list the other species 

 represented in the collection. All specimens were collected in 1919. 



DiPLOPODA. 



1. Polydesmus moniliaris Koch. 



This is a comparatively common form in the eastern United States north- 

 ward from Pennsylvania through New York and New England. In the col- 

 lection are two specimens from Ottawa, and one from Quebec City. 



2. Polydesmus serratus Say. 



A species abundant in the United States in the eastern portion and west- 

 ward to the Mississippi valley. Six specimens, adult males and females, 

 were taken at Ottawa. 



3. Blaniulus ^uttulatus Bosc. 



This interesting julid occurs throughout Europe, but is most abundant in 

 the western parts, as in France, Belgium and Germany. In those countries it 

 has been regarded as an injurious form, attacking various vegetables such as 

 beans, potatoes, beets, cucumbers and gourds.* Numerous specimens of this 

 form were taken at Quebec City in Sept., 1919. 



4. Julus coeruleocinctus Wood. 



This species is abundant from Pennsylvania northward through New York 

 and New England. In New York particularly it has frequently been accused 

 or suspected of damaging vegetable crops. It is represented in the collection 

 by specirnens from Ottawa and Quebec City. 



5. Julus fallax Meinert. 



One adult female of this species was taken at Ottawa. It is a common 

 European form, well-known both upon the continent and in England and Ireland. 

 It has also made its way by ship as far as New Zealand, from where I lia\e a 

 number of specimens. 



6. Farajulus canadensis Newport. 



One specimen irom Ottawa. Described originally trom Canada, this 

 species has also been found to occur widely in the northeastern Ihiited States. 



7. Farajulus venustus WOod. 



In the collection is a male from Alexander Bay, '^i1ou^^and Islands, N.Y., 

 taken Sept. 1, 1919. It is somewhat darker than is usual in the more t>pical 

 specimens from the middle western United States, and the gonopods are also 

 slightly variant.
