Lithohius manni var. pia var. nov. 



Similar to the preceding in general ; but all specimens examined from 

 the type locality differ in having several more articles to the antennae (21 — 23), 

 in having the spining of the anal legs uniformly 1, 3, 2, 0, and in a few minor 

 points. The ocelli in one specimen ranged thus, 1 — 4, 5, 4, 2. Coxal pores 3, 

 4, 4, 3. Lateral spines of 14th coxx much smaller than those of the 15th. 



Monterey (author). 



Lithobius paradoxus Stuxberg. 



Brown, head and antennae darker ; ventral plates and legs, especially the 

 caudal ones paler. Spines of first legs 1, 2, 1. Claw of penult legs with one 

 accessory spine. Claw of anal legs unarmed. Antennae about half the length 

 of the body. Ocelli 8 in two series. Anal legs of male crassate. 



San Pedro (G. Eisen). Probably based on a young specimen. 

 Lithobius remex Chamberlin. 



Brown ; legs paler. Ocelli on each side 6 in two series, deeply pigmented. 

 Spines of first legs 1, 2, 1 ; of anal legs 1, 3, 2, 0, the claw unarmed. Anal 

 legs in male flattened sublaterally, the plane of compression becoming nearly 

 horizontal distad. 



Shasta Springs (author). 



Lithobius kochii Stuxberg. 



Testaceous brown. Antennae short, but little more than one-third the length 

 of the body. Ocelli about 9, arranged in three series. Coxal pores 2, 3, 3, 3. 

 Spines of first legs 0, 1, 1. Anal legs short, about equalling the antennae in 

 length, in male not crassate. Claw of anal legs armed with a single claw.

Coll.). 



Lithobius sastianus Chamberlin. 



Dorsally brown, the major scuta darker along the caudal margins ; antennae 

 paler distad. Ocelli 12 in three series. Spines of first legs 1,2, 1 ; of penult 

 1, 3, 3, 1, the claw with one spine. Coxal pores very small, 2, 2, 3, 3 — 3, 3, 4, 3. 

 Lithobius utaheiisis Chamberlin. 



Yellow to brown, the legs and antennae paler. Antennae and anal legs 

 about equal in length (2.5 to 3 mm.). Spines of first legs 1, 2, 1 — 2, 3, 2; 

 of penult 1, 3, 3, 1—1, 3, 3, 2. Coxal pores 2, 2, 2, 2—2, 3, 3, 3. Length 

 7.5 — 11 mm. Rarely the anal .legs of male lack the excavation on femur indi- 

 cated in the key. 



Abundant in LItah and among the author's notes recorded from Cal. In. 

 Cal., however, it occurs chiefly as the following variety. 



Lithobius ulahcnsis var. tigaiius var. nov. 



Differing from the species apparently in never having the anal legs of 



male modified as described for that form. Specimens from Pacific Grove, 



etc., agree as follows : Last two coxa laterally armed. Spines of first legs 



1, 3, 2 ; of penult 1, 3, 3, 2, the claw armed with a single spine ; of anal 1, 3, 2, 



9, the claw unarmed. Ocelli 5 — 7 in two series. Coxal pores 3, 4, 3, 3 — 3, 4, 



4, 3, small.
