• ieiiiis Tampiya j,'cii, ikiv. 



Lateral portions of the l.ihrum eone.ive. e.ieh pictinati- with few lij;htly 

 chitini/ed prin-csses or spines, the middle portion protruding caudad and distally 

 truncate, bearing a row of stout, conical, highly cliitini/.ed teeth. I.n))pets of 

 first maxilla- very long. The claw of palpus of second niaxillii* long, smooth. 

 Cephalic plate not wholly covering the prehensorial feet. Hasal ))lati- short, 

 wider than cephalic pl.ite. Chitinous lines very strongly developed. Anal legs 

 with large claws. I ly poph.irynx strongly devehiped. bifurcate anteriorly, 

 ."spiracles all circul.ir. L.ist vnitr.il pl.it<- nioder;ite; pores sc.ittered over 

 coxopliuru'. 



Type. — Tiiiiipifia pi/liiriis sp. nov., the only species thus f;ir known. 



Tampiya pylorus sj). ikiv. 



C"ephalic plate trunc.ite c.iud;id. the sides conspicuinisly convex, anti-rior 

 portion sub-triangular; .'iboiit equal in length .and bre.-idth. Antennii- rather 

 n.irrow, flattened, of uniform width throughout. I'.alpi of second maxilla' con- 

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

 a li;ilf 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 ])rosternuni armed with two stout conical teeth. Spiracles nil 

 circular, the first not spcci.-illy enlarged, those of ultimate segments becoming 

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

 incurved. Coxoplcural pores large, eight or more on each side, niostlv scattered 

 over coxopleura. free from plate but a few covered by edge of the latter. Anal 

 legs short, ending in stout claws. I';iirs of ligs. one hundred and twenty-Hv<-.

I'amily Geophilidae 



In this f.'imily the l.abrum is tripartite, the middle pii'ce varying in relative 

 size. Till- in.'indible be.irs but a single |)ectinate lamella and no dentate lamclln. 

 The coxip of the first maxillir are coalesced at the middle. No su|)r.'iseutella are 

 present. The subfamilies rej>resented in California may be distinguished by 

 means of the following key:
