instead of being squarely truncate (the anterior plates in Chamber- 

 lin's drawing appear united to the lateral plates) ; lateral plates 

 more acute at apex, Avith the upper half of the posterior margin pro- 

 duced inward and forward. Posterior gonopods erect, rather slender, 

 hollowed in front to near the rounded apex from which numerous 

 papillate hairs curve backward; anterior ectal margin with a tri- 

 angular process directed forward. 



Penultimate joint of male legs 6 and 7 with a conical prominence 

 on the inner side larger than in N. hurhei and with the apex squarely 

 truncate and hollow (fig. 14, 5) 



First male legs sunilar to those of hurhei as shown in Chamberlin's 

 drawings previously referred to. 



Legs behind the genitalia with a long cavity in the ventral surface

Collected by Dr. O. F. Cook in the following California localities: 

 Many specimens of both sexes south of Atascadero, the type locality, 

 January 1, 1928; one female from Tejon Pass, December 14, 1927; 

 one male and many females from Grapevine, below Fort Tejon, 

 February 28, 1929. Two males, lacking one molt of maturity, from 

 Medford, Oreg., June 15, 1937, and a similar male from Chico, Calif., 

 June 24, 1937, collected by L. D. Christenson and L. S. Jones and sent 

 to me by the U. S. Bureau of Entomology and Plant Quarantine, 

 have been identified as this species. The type is a male, U.S.N.M. no. 

 1308. 



Descnption. — This species is very closel)^ related to N. minor, from 

 which it differs most evidently in the following particulars: Body 

 of the same proportion, but sometimes reaching a length of 20 mm ; 

 segments as many as 51; ocelli in fully developed specimens in four 

 series containing 18 to 22 ocelli. 



Body distinctly pigmented with violaceous-brown, maculate with 

 colorless spots. Head with vertex colored and maculate with many 

 small light spots, which sometimes are confluent; in front of this 

 area the color is unevenly peppered over the surface, becoming lighter 

 toward the front margin of the head; a very large, transverse, oval, 

 colorless area on each side between the antennae; above and slightly 

 mesad of these are two smaller rounded areas. First segment witli 

 a very large oval area mottled with light blotches on each side of the 

 fine dark median line ; these areas bounded by a solid band of color, 

 broad at the middle of both the front and hind margin and still 

 broader near the hind angles ; outside of this band the margins of the 

 segment are colorless and semitransparent, the anterior colorless 

 margin much broader than that behind. Other segments with the
