 4, 5, 5, 4 — 4, 5, 5, 5. L. pitophihis Chamberl. 



Lithobius paucidens Wood. 

 This is a large species quite readily recognized by the characters given

 g'onopods of fenial entire ; basal spines 2 — 2 to 3 — 3. The femur in anal legs 

 of male generally flattened dorsally and laterally extended for part of its 

 length. 



L. paucidens is evidently common in the southern part of the state, the 

 author having collected numerous specimens at Los Angeles, Santa Monica, 

 Laurel Canyon, San Bernardino, Santa Barbara, etc. 

 Lithobius angelits Chamberlin. 

 A species of medium size. General color reddish brown. Antennae with 

 26 — 28 articles. Spines of 1st legs 1, 3, 1 — 1, 3, 2: of penult 1, 3, 3, 1, the claw

 legs longer than antennae (ad 10 mm. and 8 mm. respectively). 



A common Mexican species reported by Bollman from the state but not 

 found by the author in any collections from the region. It is quite likely, 

 however, that it occurs in the southern parts.
