Known only from California, where it is commonest in the southern portion 

 of the state. It has not been recorded from north of Stanford. The species is 

 closest to the following one: 



Otocryptops mundus sp. nov. 

 (Figure 1.^.(1. A. B. K. F) 



Head mostly smooth, finely punctate, es))ecially over caudal and caudo-lateral 

 portions. Margined caudo-lateral and also to some extent laterally. .\11 articles 

 of antenna- pubescent or the first article smooth dorsally as in gracilis. Dorsal 

 plates 5-'i\l strongly margined laterally, the fourth more weakly so, the twenty- 

 third weakly so. Median furrows on dorsal jilates much as in gracilis. Last 

 dorsal j)late but slightly njirrowed caudad. caudal border less extended than in 

 gracilis, the lateral angles rounded and wholly without indications of spinous 

 point. Prosternum without teeth. Ventral plates from one to twenty-one with 

 a longitudinal median furrow. Last ventral plate rather deeply excavated 

 caudally. Pseudopleurn' with conspiciious, |>ointed caudal prcx-esses, decidedly 

 longer than in preceding species. Anal legs very long and stout; Iwth ventral 

 and inner spine of ))refen\ur stout and conspicuous. Brown: head and last seg- 

 ments reddish; legs and antenna- yellowish or yellowish brown, anal legs 

 darker. Length ad fiO mm. 



Kendrick, Idaho (Mann), is the only known locality thus far. 



The species is very close to the preei-ding and might even be with nason re- 

 garded as a subspecies to it. 



Otocryptops sexspinosus Say 



Brownish to deep rust red. Antenna- usually with the first two articles 

 glabrous and shining, the others densely hirsute. The prosternal margin nearly 

 straight and smooth, without any indications of teeth. Prefemur of anal legs 

 with both ventral and inner spine conspicuous. Pseudopleural processes large. 

 \'entral plates smooth, without median furrow. No median dorsal furrow or line. 



One of the commonest of all chilopods throughout most of the state but becom-
