Description of new genera and species of North 

 American Myriopoda {Julidae) 



By C. II. Bollman. 



In examining the material ol this family in the Museum of the In 

 • lima University and my own collection, I have found that the following 

 species do not appear to be described. 



Fam. A. JULIDAE, Lead!. 

 Genus I. NANNOLENE, gen. nov. 



Antennae >hort, subdavate, joints longer than wide, second and sixth subequal, 

 the laiter enlarged as in Cambala. Mandibulary combs 6 (5). Guathochilarium 

 -urn -what spatulate, stipes separated attenuated at the base, men turn entire, exposed, 

 promentum divided almost as in Cambala or Iidfymorpha; lingual lobes denticulated. 

 Segments constricted in the middle, the anterior ten segments striate from the feel to 

 the pore, striae diminishing on the other-: at the junction of the anterior and poste 

 riot" parts of almost every segment are round impressions, larger than the repugna- 

 torial pore, which extend around all the segments except the anterior 6 S. Repu 

 gnatorial pore commencing on the sixth segment, placed in the posterior part, 

 fourth segment footless. Feet long and slender. Male: First pair of legs short. 

 usual number of joints, somewhat thickened, unarmed: penultimate joint of the sixth 

 and seventh pairs of legs produced on the inner side. 



This genus is related more to Cambala, than any other, although it 

 approaches Fulomorpha in the form ol the promentum. The following 

 species is the type. 



Nanolene burkei, >p. nov. Light brown, a lateral row ol huge brown spots, 

 a brown band between eye-. Slender, not smooth or pilose. Vertex smooth, a faint 

 median sulcus, setigerous foveolae absent. Antenna' equalling the width of body, 

 pilose. bye-, distinct, triangular: ocelli 2 to 5. Segments 50 or 5 1 . Side- <>l first 

 segment striate', others moderately striate beneath, posterior margin of each segment 

 with fine parallel striae, bast segment rounded; anal valves n t marginate, pilqse:
