NOTES UPON SOME MYRIAPODS BELONGING TO THE U. S. NA- 

 TIONAL MUSEUM. 



BY CHARLES H. BOLLMAN. 



Through the kindness of Dr. Charles V. Riley, I have received for 

 examination the unidentified lot of myriapoda contained in the collec- 

 tion of the U. S. National Museum. 



This lot contains both foreign and domestic species, but in this paper 

 I have only given notes upon the forms found in the United States. 



In addition, I have included several notes upon some material sent to 

 me by Prof. L. M. Underwood, of Syracuse, X. Y. 



These specimens originally belonged to a collection, the remainder 

 of which he had presented to the Museum, and has been sent to me 

 among the material received from Dr. Eiley. 



I desire to tender my thanks to Dr. C. V. Eiley, Mr. J. B. Smith, and 

 to Prof. L. M. Underwood for various favors. 



1. Polyzcnium rosalbum (Cope). Marquette, Mich. E. A. Schwarz. 



This specimen, a female, differs from any I have seen in having the gen- 

 eral coloration more intensified. Dorsal ydates reddish-brown, paler 

 posteriorly and along margins ; antenna? almost black ; face and legs 

 mottled with a purplish shade. 



2. Platydesmus lecontii (Wood). Ace. 19542, 9, Tallulah, Ga.; L. M. Underwood. 

 Segments 89-49. 



3. Spirobolus hebes (Bollman). Ace. 14530, San Diego, Cal. 

 Segments 47, $ . 



4. Spirobolus marginatum (Say). (?) Virginia, Kuebling. Ace. 19542, 13, Tallu- 

 lah, Ga. ; L. M. Underwood. Ace. 19542, 12, Macon, Ga. ; L. M. Underwood. Seg- 

 ments of males 53-55, segments of females 52-57. 



5. Spirobolus spinigerus (Wood). Ace. 19343, Cape Romano, Fla. ; F. B. Meek. 

 Segments of female, 47-49. 



6. Spirostrepus montezumae (Saussure). El Paso, Tex. ; Potts. 



The specimen before me seems to agree in all respects with the de- 

 scriptions of S. montezumae, which has only been found in the provinces 

 of Vera Cruz and Orizoba, Mexico. This is the first record of any spe- 

 cies of this genus from the United States. 



7. Parajulus canadensis (Newport). Luray, Va. ; L. M. Underwood. 



These specimens agree in all respects with the females of canadensis, 

 but a male might show some secondary sexual differences. Segments 

 48-53. Last segment only completely mucrouate in about half the 

 specimens. 



8. Parajulus venustus (Wood). West Cliffe, Colo. ; T. D. A. Cockerell. 



9. Parajulus impressus (Say). Ace. 19542, 7, Tallulah, Ga. ; L. M. Underwood. 

 Ace. 19542, 17, Indian Springs, Ga. ; L. M. Underwood. Segments 55.
