Anal legs stouter and much longer than the penult, armed with a 

 long, stout claw; like the other legs, almost destitute of hair. 



Pairs of legs 79-81. 



Locality. — Southern California (Los Angeles, etc.). 



I am inclined to think this species the Strigamia cephalica of Wood. 

 But it is really a Geophilus, and a new name must under any conditions 

 be given to it, as the name cephalicus was previously given by Wood to 

 another species in this genus. 



Geophilus cayugae sp. nov. 



Body little attenuated anteriorly, strongly attenuated posteriorly. 



Cephalic plate with anterior and posterior margins truncate ; angles 

 well rounded; sides nearly straight, subparallel; longer than wide 

 (7.4 : 6.7). Frontal plate not distinctly separated. Basal plate two 

 and a half times wider than long. 



Claws of prchensorial feet when closed barely reaching the front 

 margin of head ; presternum with chitinous lines, front margin widely 

 angularly emarginate, unarmed; femur and claw also unarmed. 



First two spiracles large, subcircular, those following circular, gradu- 

 ally decreasing in size caudad, the last very small. 



Last ventral plate rather narrow; sides straight, converging pos- 

 teriorly. Last coxae enlarged, covered over entire exposed surface, 

 except posteriorly, with large and small pores, of which there are 30 or 

 more on each side. 



Anal pores distinct, of moderate size. 



First pair of legs much smaller and more slender than those following, 

 the second pair somewhat intermediate in size. Anal legs stouter and 

 much longer than the penult, each armed with a very long and slender 

 claw. 



Pairs of legs 65 ( ? ). Length 55 mm. 



Locality. — Ithaca, New York. 



Evidently close to lanius Br5l. In cayugw, however, the anal pores 

 are conspicuous, not concealed (absent?) as in lanius. Also the an- 

 tenna3 are relatively much shorter than in lanius, the cephalic plate is 

 of a different shape, the number of pleural pores is much larger and 

 cover the pleurse above as well as below and laterally, and the pairs of 

 legs number 65 ( 9 ) as against 57 ( 9 ) in lanius. 

 Mecistooephalus anomalus sp. nov. 



Body and legs waxy yellow; head pale, somewhat reddish brown; 

 antennae pale yellowish brown. 



Gradually attenuated from the head caudally. 



Cephalic plate longer than wide in ratio of 7 : 4.75; strongly nar-
