spicuously narrowed from third fourth of length ccphalnd and ahniptly narrowed 

 caudad; the head relatively very small. The eeplmlic plate is relatively wide, 

 Well rounded in front, almost completely concealing the |)rehensorial feet from 

 above. The flat anteiuiw are short, contiguous at base and pointed distad. Claw 

 of prehensorial feet not att-iining front margin of head. Ventral pores in n 

 sharply delimited median area which varies from circular to transversely elliptical 

 in outline. Last ventral plate very wide, the numerous small coxopleural pores 

 aggregated mostly along its edges. 



Specimens have been seen by the author from Stanford, Claremout and Los 

 Angeles. It is also known from .^au l)ii-;j(i ;in<l .M;irgarita Island. 



Notobius inermis Wimd 



L'nder the name llimaiilarium inermis. Wood described an individual from 

 the Santa Crux Mountains. lie states that it is very similar to teniopsis but 

 differs in having only one hundred and fifteen pairs of legs. The head is described 

 as tri:ingul:ir and moder.'itely wide, the .-intennu- short and said not to be acuminate. 

 l''ecl robust, short. 



Genus Gosiphilus ^vii. nov. 



Body much flattened dorso-ventrally, Labruni deeply incised at middle. The 

 coxostermnn of first maxilln* deei)ly incised at median line but co.xa- not separated 

 pruxiinally. Dentate jilate of mandible rather narrow. Paratergites or suprn- 

 scutella absent. Last ventnil i)late wide. Coxopleural ])ores few, mostly covered. 

 Anal legs dawless. 



Apjiarently most closely allied with Uaplophilus. Established for three 

 sj)ecies, all of which wcur in California and two of them known from nowhere 

 else.

Gosiphilus minor sp. nov. 



Cephalic plate widest caudad. conspicuously narrowed .'interiorly, sub-trian- 

 gular, wholly covering the prehensorial feet; caudal margin weakly produced from 

 lateral corners to a very obtuse angle at middle; much wider than long (as 31 :2,S). 

 Basal plate very wide, narrowed from its anterior end caudad, two and one-half 

 times wider than long. Antennae short, thick, contiguous at base. Prosternuin 

 much wider than long (^8:17); chifinous lines very strongly developed. Prehen- 

 sorial feet weak, joints unarmed, claws not attaining front margin of head. 

 Spiracles all circular, the first considerably larger than the second. Ventral jwrcs 

 in a sharjily defined transversely cllijitical area. Last ventral plate very wide, 

 almost wholly covering the coxopleura-, sulxju.adrate, the sides but slightly con- 

 verging caudad. Coxopleural pores few, partly covered. Anal legs in male
