THE MYRIAPODA OF NORTH AMERICA. 197 



5. Orthomorpha karschi, sp.no v. Habitat: East Indies and part of Polynesia. 



6. Orthomorpha gracilis (Koch). Habitat: Austria (only found in a few hothouses, 



and seems to have been introduced). 



7. Orthomorpha dasys Bolluian. Habitat: Baltimore, Maryland (introd'-^ed, 



found only in hothouses). 



11. Polylepis klugii (Brandt). 



(Polylepis, nom. gen. nov. for Pachyurus Saussure, which is preoccupied by 

 Pachyurus Agass., Pisces, 1829.) 

 Ace. 18478, Guanajuato, Mexico; Duges, o. 



The two American species should now stand thus : 



1. Polylepis klugii (Brandt). * 



2. Polylepis abstrusus (Karsch). 



12. Fontaria fraterna (Saussure). 



1859. — Polydesmus fraternus Saussure. Linn.Ent., 322 (Mexico). 



1881. — Polydesmus (Fontaria) augelus Karsch. Troschel's Archiv f. Naturgesch., 39 



(Puebla, Mexico). 



Ace. 17139, Puebla, Mexico; male and female. 



These specimens agree in all points with Saussure's description of 

 fraternus. 



P. angel its may be different (1. 50 mm ), but its copulation foot is iden- 

 tical with that of the specimens before me, which are the same size of 

 fraternus. 



13. Fontaria otomita (Saussure). 



1859. — Polydesmus otomitus Saussure. Linn. Ent., 322 (Cord, ra, Mexico) 

 Ace. 1X478, Guanajuato, Mexico; Duges; 4 males, 1 female. 



Copulation foot of male subsimilar to that of fraterna. Apex bifid; 

 angle between them greater than a right; the upper lobe smallest and 

 pointed; the lower recurved, broader, subtruncate, and is the branch 

 through which the spermatozoa are conveyed ; not far below the apex 

 on the interior side is a small triangular spine. Basal spine rather 

 short, cylindrical, its apex curved upwards, separated from rest of foot 

 by a wide angle. Basal part of foot with short, almost spine-like hairs; 

 a few at the upper interior angle much longer. 



14. Linotcenia chionophila (Wood). 

 No. 83, U. S. Nat. Museum; Bering Island; Stejneger. 



One small broken male, which I have been unable to separate from 

 the American species. Pairs of legs, 43. 



15. Scolopendra morsitans Linnaeus. 

 Ace. 14150, Paramaribo, Surinam; U. S. Fish Commission.
