NOTES UPON THE NORTH AMERICAN MYRIAPODS DESCRIBED BY 



C. L. KOCH. 



BY CHAKLKS n. nOLI.MAN. 



As l)r, Koch's papers* nUatin^' t<> tlio Nortli Aniorican myriapods 

 seem to liav«' been overlooked hy jnevioiis authors, I have tlioujjht it 

 best to briii^j: togetlier in a ])aper luy notes relating- to his species. 



The second of Dr. Koch' works is merely a more extended account of 

 the species mentioned in his first work, with ]tlates of eacli. 



Of tlie fourteen new species described by Koch only five are good. 

 I desire to exjuess my thanks to Dr. Lucien M. Tnderwood, of Syr- 

 acuse, N. Y., for the privilege of exanuning a coi>y of Koch's "Die 

 Myriapoden." 



1. Spirostreptua nutans Koch. Syst. Mvr.. 101. 1S47 (Xorlh Aniiriv<i); Die Myr., i. 



11, pi. 7, lig. 14, 1S(;:!. 



As the descrii)tions and figures of this species plainly show, it should 

 be referred to Parnjuhia caniKlcnsis (Newport). 



2. Spirostreptua clavipes Kooli. Syst. Myr., 105, IHIT (Penutiyh-ania); Die Myr., ii. 



ICS, pi. ll.->, tig. 22H, 1863. 



This species, described from a male speciinen, is identical with the 

 preceding. The differences Koch draws between them are sexual. 

 His figure of the first pair of legs .seems to indicate that his specimens 

 were not full grown. 



3. Campodes flavicornis Koch. Syst. Myr., 12(5. 1847 (Pennsiilrania)', Die Myr., ii, 



17, pi. ()8, lig. 140, ISiK^. 



This species, the type of the genus Campodes, has been well de- 

 sciibed by Koch. It is the same as Spiroslreplion ('a'Hi(>annuIatii.s Wood 

 and the Pseudotremia viidil of Cope. Campoden Koch { = (JryptotrichuH 

 I'ackard). 



4. Cainpod='s fuscicornis Koeh. Syst. Myr., 127, 1847 (Pennsylrania); Die Myr., ii, 



16, pi. 68. fifj. 1.^9, 1863. 



This new species, as Koch has liinted, " VieUfiehi nur Ahart der 

 rorifien,'''' is only a slight c(dor variety of the preceding, and is not 

 worthy of specific or subspecific rank. 



5. Scytonotus scabrioollis Koch. .Syst. Myr., 130, 1847 (Fennsjilrania) ; Die Myr., ii, 



41, pi. 80, tig. 16.->, 1863.
