chitinous lines; its anterior median margin armed witli two stout conical teeth. 

 Stipraseutella absent. Ventral pores absent. Antenna' flattened but of equal 

 width from base to ajiex, being not at all attenuated. Pores of coxopleurae scat- 

 tered. 



This family is evidently very close to the Gonibregmatidae, a family occur- 

 ring in the Phili|)i)incs and East Indies, with which it forms a natural group. 

 One genus .-it present known. 



Genus Tampiya gen. nov. 



Lateral portions of the labrum concave, each pectinate with few lightly 

 chitinized processes or spines, the middle portion protruding caudad and distally 

 truncate, bearing a row of stout, conical, highly chitinized teeth. Lappets of 

 first maxillae very long. The claw of palpus of second maxillas long, smooth. 

 Cephalic plate not wholly covering the prehensorial feet. Basal plate short, 

 wider than cephalic plate. Chitinous lines very strongly developed. Anal legs 

 with large claws. Hypopharynx strongly developed, bifurcate anteriorly. 

 Spiracles all circular. Last ventral plate moderate; jiores scattered over 

 coxopleurje. 



Type. — Tampiya pi/lonis sp. nov., the only species thus far known. 



Tampiya pylorus sp. nov. 



Cephalic plate truncate caudad, the sides conspicuously convex, anterior 

 portion sub-triangular ; about equal in length and breadth. Antennae rather 

 narrow, flattened, of uniform width throughout. Palpi of second maxilla con- 

 spicuously flattened. Basal plate very wide, wider than head, about three and 

 a half times, or a little more, wider than long. Prehensors when closed with 

 claws almost even with front margin of head; joints all unarmed. Anterior 

 median margin of prosternum armed with two stout conical teeth. Spiracles all 

 circular, the first not specially enlarged, those of ultimate segments becoming 

 very small. Last ventral plate rather narrow, short, caudal margin a little 

 incurved. Coxojjleural )K)res large, eight or more on each side, mostly scattered 

 over coxopleura, free from ))late but a few covered by edge of the latter. Anal 

 legs short, ending in stout claws. Pairs of legs, one hundred and twenty-five. 



Locality. — Sausalito. 



Family Geophilidas 



In this family the labrum is tripartite, the middle piece varying in relative 

 size. The mandible bears but a single pectinate lamella and no dentate lamella. 

 The coxae of the first maxilla" are coalesced at the middle. No suprascutella are 

 present. The subfamilies represented in California may be distinguished b_v 

 means of tiie following key:

 on each side a strongly chitinized suture running from the ecto-caudal 

 angle cei)halo-mesad (pleuro-sternal suture). Subfamily Chilenophilinae
