Mitopus dorsalis (M. dor-sa'lis). — In the second legs the tibia 

 is subequal to or shorter than the metatarsus; there is no false 

 articulation in the metatarsus of the 'first legs; the colour of the 

 body is gray and white. This is an Alaskan species. 



Mitopus montanus (M. mon-ta'nus.) — This species agrees, 

 with the preceding in having the tibia of the second legs subequal 

 to or shorter than the metatarsus; but differs in having two false 

 articulations in the metatarsus of the first legs and in being brown 

 or black and white. It occurs in New Hampshire. 



Genus LACINIUS (La-cin'i-us) 



In this and in the following genus there is a group of spinules 

 on the anterior margin of the carapace, the eye-tubercle is spinose, 

 the palpal claw is smooth, and the femur of the palpus is provided 

 with prominent spines. In this genus there are no false articula- 

 tions in the metatarsus of the first legs, and the eye-tubercle is 

 more remote from the anterior margin than in the following genus. 



Lacinius texanus (L. tex-a'nus). — The metatarsi of the first 

 and third legs are banded in the middle, and there are very promi- 

 nent spines at the tips "of the femora and patellae. Occurs in 

 Texas. 



Lacinius ohioensis (L. o-hi-o-en'sis). — The metatarsi of the 

 first and third legs are not banded; the legs are longer than in 

 the preceding species and the spines at the tips of the femora and 

 patellae are less prominent. Occurs in the Eastern and Middle 

 States. 



Genus OL1GOLOPHUS (Ol-i-gol'o-phus) 



There is a group of spinules on the anterior margin of the 

 cephalothorax and the eye-tubercle is spinose; the palpal claw is 

 smooth; the femur of the palpus is armed with prominent spines; 

 and there is at least one false articulation in the metatarsus 

 of the first leg. 



Oligolophus pictus — -The colour of the dorsum is mottled 

 ash-gray with a dark central band extending the whole length 

 of the body; this band is suddenly contracted near the posterior 

 margin of the cephalothorax, then gradually expanded until it 

 reaches the end of the anterior third of the abdomen, where it is 

 suddenly contracted; behind this point the band is again widened
