THE MYRIAPODA OF NORTH AMERICA. 183 



1. Parajulus venustus Wood. 



Julus veitHxtitx Wood. Proc. Phila. Acacl. Xat. Sci., 10, 1864 (Illinois). 

 JithiK retinntKx Preudhommo <!< I'.onv. Ann. Soe. Ent. Beljj., 62, 18M. 

 Julus impressus Wood, etc. 



In this paper I have regarded the Julux rcn until* of Wood as repre- 

 senting a valid species and not identical with />///m'.s-\/(.v, as Wood him- 

 self and otlier writers have later held. 



In the Trans. Ainer. Phil. Sue., 11M>, lS(i."i, V\'ood makes rnuiHtiiti 

 and intprcHsiiH the same, and mentions a specimen from Georgia. I 

 regard the specimens from Georgia as the true ////;;>V.VM.V, which is found 

 in Indiana, Georgia, and Florida, while rrmuitux is found in Colorado, 

 Kansas, Minnesota, Michigan, Illinois, and Indiana. 



2. Parajulus diversifrons (Wood;. 

 Common. 



3. Parajulus ellipticus Hollmau. 



This is a very common species, if not even abundant. 



4. Lysiopetalum lactarium (Say). 

 Several specimens were sent in the last collection. 



5. Campodes flavicornis Koch. 



Not uncommon. Most of specimens sent were very young. 

 6. Craspedosoma atroliueatum Bollmun. 



A single female from here seems to agree in all the principal char- 

 acters with the types of C. a/ro/inctitiiiiij which are from British 

 Columbia. 



7. Leptodesmus borealis, sji. n<>\. 



Anterior parts of segments reticulated with black, posterior border, 

 lateral carinse, legs and antenna' yellow, an indistinct, broad, black 

 median, dorsal line. Body robust, narrow, strongly snbterete. Vertex 

 smooth, stilcus extending to base of antenna-, setigerous fmeohe. An- 

 teniipe short and filiform. First segment semicircular, sides slightly 

 margined, posterior border somewhat emarginate. Other segments 

 more or less corrugate, especially above lateral carina-. Lateral carin;e 

 small, thick, anterior border not prominent, rounded, posterior scarcely 

 angulated, but produced posteriorly into thick, short, rounded lobes. 

 Mucro of last segment large and thick. TJepugnatorial pores moder- 

 ately large, lateral and subapieal. Legs moderately long, extending 

 beyond sides of body. Length of body 9 , 12.">. ">"""; width and height, 

 3 inm ; length of antenna', L'.4' 



l,f'l>t<>(l<'NinnN Itori'iil/x differs from all the species found in Eastern 

 United States by its thick lateral carina' and the strongly terete body. 

 It approaches more to L. <nn- (\Yood) from Oregon. 



The above description is based on a female, which was collected near 

 Winona by Prof. Hol/iuger in the fall of 1S87.
